These newly isolated organisms will allow us to obtain a better understanding of the biochemistry and genetics of acetanilide herbicide catabolism by microorganism and will provide new tools for the bioremediation of environments affected by these herbicides. MATERIALS AND METHODS Chemicals. Metolachlor was a gift from Syngenta Crop Protection, Greensboro, NC. Uniformly ring labeled metolachlor was graciously supplied by Syngenta Crop Protection. Acetochlor and alachlor werepurchased fromChemService. Uniformlyring labeled alachlor was gra ciously supplied by Monsanto Corp. The metolachlor standard for LC MS analysis was obtained from Chem Service. Stock solutions of metolachlor, acetochlor, and alachlor were prepared in water and stored at 4 C until used.

All Apoptosis other chemicals were obtained from Fischer Scientific, Pittsburgh, PA. Growth Conditions and Isolation of Microorganisms. Silty clay soils from Spain, which had 10 and 2 year histories of metolachlor and S metolachlor application, respectively, were used in this study. These soils received 3. 75 kg/ha of metolachlor once per year. Microorganisms were obtained from the soil following enrichment for 5 days inminimal medium using metolachloras the sole sourceof C for growth. The metolachlor was added after autoclaving,and the pHwas adjusted to 7. 0. The same procedure was used for media containing acetochlor and alachlor. All of the experiments were conducted at 30 C, because the isolated yeast had difficulties growing at lower temperatures. Cultures were incubated for up to 3 days, and microorganisms were isolated using a dilution plating technique and by picking isolate colonies.

Presumptive metolachlor degrading microorgan isms were restreaked for purity, several times, Angiogenesis on the same medium and examined microscopically following gram staining. The MM was amended with 0. 04% yeast extract, 0. 05% sucrose, or both to enhance the growth of microorganisms at the beginning of the exponential phase of growth. Microbial Identification. DNA was extracted from bacterial and yeastcellsbyusingafreeze thawandsonicationtechnique. Forthebacteria, the 16S rRNA gene was amplified by PCR using universal bacterial primers 8F 5 GAGTT and 92R 5 TACCTT as described by Polz and Cavanaugh. These primers were also used for sequencing. For the yeast, three different regions of 18S rRNA were amplified and sequenced.

The universal fungal primers 1F 5 AACCTGGTT and 1772R 5 TGATCCTT were used for the amplification and se quencingofthe 18S rRNAgene. The sequences ofthe ITS1 5. 8S ITS2 regions were determined using primers ITS1 and ITS4. Primers NL1 5 CATATCA and NL4 CFTR 5 GTCCGTGT were used for amplification of the D1/D2 seg ment of 26S rDNA. PCR reactions were carried out using an iCycler thermocycler, using different protocols depending on the primers used. For the 16S amplification, an initial denaturation step of 3 min at 94 C was followed by 35 cycles of amplification consisting of 1 min at 94 C, 1 min at 50 C, and 2 min at 72 C. For amplification of 18S rRNA gene samples were denatured for 10 min at 95 C, followed by 30 cycles of denaturation at 95 C for 15 s, 15 s at 50 C, and elongation at 72 C for 2 min, with a final extension step of 10 min at 72 C.

c-Met Signaling Pathway The ITS region was amplified using ITS1/ITS2 primers and an initial denaturation step of 10minat95 C. Thiswas followedby30cyclesofdenaturationat94 Cfor 30 s, 30 s at 58 C, elongation at 72 C for 30 s, and a final extension step of 10 min at 72 C. For amplification of the 26S rRNA gene with NL1/NL4 primers, the reaction was initiated with an initial denaturation at 94 C for 10 min. This was followed with 36 cycles of 30 s at 94 C, 30 s at 52 C, and 1 min at 72 C, with a final extension at 72 C for 5 min. DNA sequencing was done at the University of Minnesota BioMedical Genomics Center. All PCR products were purified by using a QIAquick PurificationKit priortosequencing. Sequences were analyzed with Applied Biosystems Sequence Scanner software v1.

0 and were assembled HSP by using Clustal W2. Sequence identity was determined by using BLAST. Species identification was obtained by using BLAST, sequence match software of the Ribosomal Database Project RDP II and the CBS Yeast Database. Additional biochemical tests were performed to more accurately assign species status to the isolated yeast. The yeast was grown in the presence of a discriminatory carbon source, in MM containing glucose, sucrose, D xylose, trehalose, maltose, starch, rhamnose, galactose, inositol, lactose, D arabinose, or D mannitol. Plateswereincubatedat30 Cinthedark, and growth was recorded 24 96 h after inoculation. Microbial Growth. The influence of metolachlor on the growth kinetics of the isolated yeast and bacterium was determined. Cells were grown at 30 C in 250 mL flasks containing 100 mL of MM medium and 50 g mL metolachlor, pH 7. 0, with or without 0. 05% sucrose, 0. 04% yeast extract, or both.

Initial results have been reported from a phase I study using a 33 escalation design with a single dose of GDC 0941 and a 1 week washout, followed by GDC 0941 QD administered on a 3 week on, 1 week off schedule. A doseproportional increase in drug exposure was observed from 15 to 450mg.  phosphorylation in platelet rich plasma at doses above 80mg and a decrease ABT-737 in RPS6 immunostaining in tumours. In addition, objective decreases in metabolic activity as measured by positron emission tomography of fluorodeoxyglucose have been observed in patients, tumours at doses above 80mg. GDC 0941 was generally well tolerated and exhibited signs of antitumour activity in a variety of cancers including breast, ovarian cancer, gastro intestinal stromal tumour and melanoma patients. Toxicities include fatigue, nausea, diarrhea and rash. Transient hyperglyceamia has been described. GDC 0941 is being evaluated in non small cell lung cancer in combination with paclitaxel and carboplatin with or without bevacizumab.
So far, these combinations appear to be well tolerated and no sign of pharmacokinetic interaction have been observed. Dose escalation is ongoing and clinical activity has AZD8055 been recorded. A phase II study in breast cancer is recruiting In an initial phase 1 dose escalation study evaluating an intermittent dosing schedule, PX 866 was well tolerated with diarrhoea and nausea observed as main toxicities. PX 866 was rapidly converted to an active metabolite which demonstrated improved potency relative to parent compound in kinase and cellular assays. PX 866 was further evaluated using a continuous dosing schedule and has been well tolerated at 8??mg per day and associated with better disease control in heavily pre treated patients than intermittent dosing.
Clinical responses have been observed in pancreatic islet cell, colorectal, and prostate cancer. Predictive biomarkers are being explored. Patients were treated at 6 doses of BMK30 ranging from 12.5 mg to 150 mg. The maximum tolerated dose was 100 mg. Treatment related adverse events included rash, hyperglycaemia, diarrhoea, nausea, anorexia, pruritus, fatigue, mood alteration, malaise, vomiting, and mucositis. Preliminary pharmacokinetic analysis showed rapid absorption and low clearance from plasma leading to steady state drug exposure estimated to be potentially efficacious based on preclinical data. Downregulation of pS6 in skin was seen in all patients at 100/150 mg. At 100 mg, 8 of 10 evaluable patients showed metabolic partial response by FDG PET.
Clinical responses were observed in triple negative breast cancer, colorectal cancer, angiosarcoma and lung cancer. 5.2. Dual Pan Class I PI3K/mTOR Inhibitors The safety profile and tolerability of the dual pan PI3K/mTOR inhibitors generally appears to be similar to that of the paninhibitors. Several organizations are developing candidates with both profiles and it is currently unclear what the ideal PI3K family isoform selectivity profile or profiles in the clinic will be. Signs of clinical activity are also encouraging for the development of these agents. The first reports from clinical trials conducted in patients with solid tumours showed promising drug safety and tolerability for NVP BEZ235 with signs of clinical activity in patients with tumours bearing PI3K pathway alterations.

direct combustion of shell material is easier and less time consuming than acidification. In museum collections bivalve shells are traditionally dry stored, whereas soft tissues are preserved in 70% ethanol, sometimes after fixation with 10% formalin. However, often the whole animal is preserved in ethanol and shells are not stored separately. For the application of these preserved specimens in the investigation of past d N values it is essential to know if liquid preservation methods have an effect on the d N values of bivalve shells and if this effect is predictable. The effects of liquid preservation on the d N values of biological tissues have been examined in a variety of For testing the in uence of CaCO 3 content on d N measurements, different mixtures of acetanilide with inorganic pure CaCO 3 were made, containing between 0 and 10.

4 weight % N. Powder calcite samples were loaded into 4 _ 6 mm tin cups and weighed. d N values were measured using an elemental analyzer coupled via a CONFLO III to a ThermoFinnigan Delta V t isotope ratio mass spectrometer. An inline soda lime CO trap was used to scrub MLN8237 CO 2 from the gas stream entering the gas chromatography column of the EA. IAEA N1 was used as a standard, with an accepted value of 0. 4 _ 0. 2% Long term. standard reproducibility is better than 0. 1% for samples nature, even samples between 5 and mg N provided reasonable data. There is also an upper limit to the amount of shell material that can be loaded into the EA, but this was not evaluated here.

This method is robust because calcium carbonate com pletely decomposes around 8258C and the ash combustion Nilotinib in the EA was around 10208C, therefore, all N should be released from the matrix and carried to the IRMS. Moreover, previous studies have used an EA IRMS system to combust Fig. 2 that the narrow and near symmetrical peak shapes are similar for both shell carbonate and synthetic mixtures, which suggests that both matrices are reacting similarly in the EA IRMS. We therefore argue that it is possible to measure carbonates for d C analysis. It is clear from the traces in larger than 30 mg N. d N values are expressed in % vs. atmospheric nitrogen. Pure synthetic CaCO 3 had peaks similar to empty tin cups, empty tin cup 1/4 0. 49 Vs) and therefore did not contribute much to the calculated delta values. The acetanilide standard had a d N value of 2.

12 _ 0. 13% when it was run without PI3K Inhibitors synthetic CaCO 3 and was _2. 02 _ 0. 11% when it was run with 98. 4 to 66. 8% CaCO 3. These values are not significantly different. In addition, during a preliminary trial, we ran 0. 4 mg of the IAEA N1 ammonium sulfate SO 4) standard in. 72 mg CaCO 3 and found no offset from N1 standards run without CaCO3. Our results show that samples with as little as 20 mg N can provide accurate d N values. Prior acidification is not required to eliminate the carbonate matrix to produce accurate results, as has been previously reported. It should be noted that mollusks with very low organic matrix in their shells may require a pre concentration step to reduce the poorer precision of small samples. However, considering the large fractionations associated with nitrogen isotopes in Figure 1.

Mass Spectrom. 2011, 25, 675 680 Letter to the Editor tissue is subject to metabolic turnover and is thus repre sentative for a specific time window, see e. g., Paulet et al,. while the shell samples averaged at least 1 year of growth. This makes comparing soft tissues with shell organic matrix difficult. However, as shown in Delong and Thorp, tissues with slower turnover rates, such as the adductor muscle, are better for comparisons with metabolically inactive shells.

Most previous studies that report differences between skeletal d N and soft tissue d N do not take the different amounts of time being averaged into consider ation. Moreover, HSP many studies compare whole body tissue d N data to shell data while it is known that different organs can have quite different d N values, sometimes as much as 5% in the same animal. This may explain why Dtissue shell values for the same species of clam range from 0. 2 to 2. 4%, see ODonnell et al.. Soft tissue d N data from M. edulis specimens collected at three different periods in 2002 from Knokke show significant changes throughout the year, which would be averaged in the shell samples we analyzed. Taking the average of these 25 soft tissue data results in a Dtissue shell value of _1. 5 _ 1. 0%. In the future it is important to compare tissues and shells that represent the same time period.

xestobii wasalsoshownheretorapidlymineralizeup to 25% of metolachlor after 10 days of growth. Because differ ences in mineralization rates among microorganisms in soils are likely due to both biotic and abiotic factors, more studies are needed to assess the contribution of mineralization to loss of this herbicide in soils. Results of mass balance analyses indicated that 5% of metolachlor in the culture medium was present in C. xestobii and B. simplex cells following incubation with metolachlor. This result indicated that metolachlor was not significantly incorporated into biomass and, thus, metabolites that were not mineralized were likely released into the growth medium. Our results are in contrast to those reported in ref 17, which reported that 80% of ring labeled metolachlor added to a microbial community was removed from the medium and accumulated inside cells.

Mechanism of Degradation. The mechanism by which metola chlor is transformed by C. xestobii is not clear. Because Pazopanib analytical standards of possible metolachlor metabolites were not available, we used the University of Minnesota Biocatalysis/Biodegrada tion Database Pathway Prediction System to predict plausible pathways for the microbial degradation of metola chlor. The PPS identi fied 22 possible molecules with molecular ions 190. Comparison of the possible molecular ions from the total ion current plot of culture medium obtained following growth of C. xestobii on metolachlor resulted in no positive matches. Also, HPLC fractionation of the spent medium following growth of C.

xestobii in uniformly ring labeled metolachlor did not result in any peaks that had 2% of the applied C, other than the metolachlor Pazopanib peak, leading to difficulty in extrapolating a degra dation pathway. Although it is tempting to speculate that dechlorination was not a major mechanism for the degradation of metolachlor by the isolated yeast, too few data are available to accurately determine this. Consequently, the pathway by which metolachlor is transformed by C. xestobii is currently unknown and awaits further analyses. In summary, in this study we report on the isolation of a bacte rium and yeast that have the ability to catabolize metolachlor. We also show that the yeast C. xestobii uses metolachlor as a sole C and energy source for growth and is able to mineralize t. this compound under controlled laboratory conditions.

Although otherfungalandbacterialstrainshavebeenisolatedthatareableto Cannabinoid Receptor partially transform metolachlor, most attempts to isolate pure or mixed microbial cultures capable of mineralizing metolachlor have been unsuccessful. Whereas the degradation of metola chlor has been previously studied with a pure culture of the fungus Ch. globosum, which also used this herbicide as a sole source of C and energy, gas liquid chromatographic analysis of the concen trated extract from resting cell experiments with this fungus showed that at least eight extractable products were produced fromtheoriginalcompound. TiedjeandHagedorn reported that the major product of alachlor degradation by this fungus was likely 2,6 diethyl N aniline, and McGahen and Tiedje reported that the co metabolism of metolachlor by Ch.

globosum is thought to occur by removal of one or both R groups from the nitrogen atom and subsequent dehydrogenation of the ethyl substituent. These authors also postulated that the HDAC-42 fungus may eventually remove the chloro, methoxy, or ethoxy substituent from the R groups. In addition to fungi, bacteria have also been reported to transform alachlor. For example, Sette et al. reported that a Streptomycetes sp. strain degraded ??60 75% of the alachlor within days to produce indole and quinoline deriv atives, and Villareal et al. reported that Moraxella sp. strain DAK3 respired and grew on N substituted acylanilides containing methyl, ethyl, or isopropyl substitutions, but failed to grow on alachlor and metolachlor. In contrast to previous studies with fungi, the isolated C.

xestobii strain degraded 50% of metolachlor after 4 days of growth, and no metabolites, such as the ethanesulfonic acid and oxanilic acid, were detected in the growthmediumbyHPLCanalysis. A. flavus and A. terr ??cola PARP have been also described as metolachlor degrading fungi, reducing the half life of this herbicide from 189 to 3. 6 and 6. 4 days, respec tively. Coupled with data showing that some fungicides significantly reduce metolachlor dissipation in soils, results from our studies are consistent with the notion that soil yeast and other fungi may be responsible for significant transformation of metolachlor in soils. Moreover, because degradation of metola chlor by C. xestobii was fairly rapid and resulted in the miner alization of this herbicide, our data suggest that this yeast may eventually prove to be useful for metolachlor bioremediation efforts. More studies, however, are needed to determine whether this yeast is also able to metabolize and mineralize other aniline herbicide compounds and to identify metabolites produced dur ing the degradation process.

Nitrogen stable isotope ratios have successfully been applied in the study of trophic linkages, as well as of human impacts in aquatic ecosystems. Anthropogenic wastewater input typically elevates d N values in dissolved inorganic nitrogen and this N enrichment subsequently propagates throughout the food chain. Bivalve mollusks are of interest for studies of this human in uence since they are primary consumers and are known to trace environmen have, for example, been found to correlate with the fraction of residential development in watersheds around lakes and salt an ecosystem, before anthropogenic nitrogen input, d N records need to be extended into the past. Bivalve shells can be useful for this, since they are often abundant in archaeological deposits as well as historic museum collec tions.

A predictable relationship has been demonstrated between the d N values of shell organic matter and soft tal d N variability. The d N values of their soft tissues marshes. To determine the undisturbed d N values in tissues and d N values of this organic matrix indeed trace anthropogenic in uences. animals. Syva??ranta et al. found that neither formalin nor ethanol had a significant LY294002 effect on d N values of preserved zooplankton and macroinvertebrates. However, in fish muscle, enrichments of 0. 5 to 1. 4% have been found after fixation in formalin and subsequent preservation in etha studies, but generally preservation effects on tissue d N found that ethanol preservation lowered d N values of the soft tissues of the freshwater bivalve Corbicula uminea by 0. 39% after 6 months.

Similarly, in the freshwater mussel Amblema plicata, ethanol preservation for MEK Inhibitors 1 year caused a contrast, some other workers found higher d N values for liquid preserved mollusk tissue samples in comparison to frozen or dried samples. Ethanol preservation for 12 weeks resulted in a non significant enrichment in octopus and vulgata, tissue d N values increased up to 1. 1% and 1. 0%, respectively, after treatment with formalin for 2 days and ethanol for 6 24 months. In summary, wet preserved specimens typically exhibit a small enrichment in nol. Results on mollusks differ among values are small in short term studies. Sarakinos et al. change of _0. 23% in tissue d N values. In Littorinid tissues. In Mytilus galloprovincialis and Patella N, but this effect is variable between studies.

We report herein the evaluation of the method of simple combustion without acidification by testing the in uence of CaCO 3 content on d N values of different mixtures of acetanilide and synthetic pure CaCO 3. We also investigate the fractionation between tissue and shell organic matrix in the bivalve Mytilus edulis. Finally, we examine the effects of long term ethanol preser Neuronal Signaling vation on d N values of bivalve shell organic matrix. For the comparison of d N values of mantle tissue and shell organic matrix, three specimens of the blue mussel Mytilus edulis were collected in 2002 in Knokke, Belgium investigation of the long term effect of ethanol preservation, six shells from the Royal Belgian Institute of Natural Sciences collected at Dudzele on 27 March 1936 were selected.

DNA Damage Three individuals were stored dry and three individuals were preserved in ethanol along with whole soft tissues. In addition, dry stored shells from three individuals collected at a nearby site at Lissewege on 22 November 1938 were obtained from the same museum and one shell, collected on 3 June 1935 at Knokke, was obtained from the Dutch National Museum of Natural History, Naturalis. All shell samples were rinsed with deionized water and left to dry. The periostracum was completely removed with a Dremel abrasive buff. Calcite samples were taken from the outside of the shell with a hand drill, the inner aragonite layer was avoided. Between 10 and 20 mg of calcite powder was collected, covering an area of at least 1 year of the most recent growth.

The mantles from the ethanol preserved specimens were dissected, rinsed NSCLC with Milli Q grade water and dried overnight at 608C and pooled. An aliquot of the ethanol these specimens were preserved in. For the Various sample preparation techniques have been used to analyze d N values of skeletal organic matter, such as acidification or simple combustion of whole skeletal material. These methods are also used in analysis of organic matter. Animal soft tissue samples contain varying amounts of CaCO 3, which will introduce a bias in d C measurements. Therefore, samples are generally treated with an HCl solution before analysis. However, the acidification process in itself may in uence d N values, although some authors found no effect of typically avoid acidification of samples for d N analysis and will run one set of non acidified samples for d N and one CaCO 3 on d N analysis, then avoiding acidification would be the method of choice for d N analysis of shell organic matter.

Vertically aligned CNTs can be coupled with enzymes to provide a favorable surface orientation and act as an electrical connector between their redox center and the electrode surface. Figure 3 showed the assembly of the CNT electrically contacted WYE-354 GOx electrode. Plugging enzymes into the CNTs by this way. Different types of glucose biosensors have been developed in recent years. Tsai and co workers developed a nanobiocomposite film by incorporating functionalized MWCNTs and GOx into polypyrrole film for a highly sensitive glucose biosensor. The amperometric response of the optimized biosensor displayed a sensitivity of 95 nA/mM, a linear range up to 4 mM, and a response time of about 8 sec. Huang et al. loaded MWCNTs and GOx on a graphite disk using a LBL assembly technique to construct a glucose biosensor.
The current response to glucose was highly dependent on the number of layers and the maximum response was obtained at 6 layers of MWCNTs/GOx with the detection limit of 90 M. Liu and Lin also applied LBL assembly technique to construct a sandwich like structure, PDDA/GOx/PDDA/CNTs, for a reproducible and stable glucose biosensor GDC-0449 while Zhao and Ju added poly with PDDA to construct multilayer membranes. They modified gold electrode with 3 mercapto 1 propanesulfonic acid and then bilayers of the PDDA and PSS were formed on the modified Au surface. PDDA wrapped MWCNTs and GOx was then assembled through LBL technique. Wang et al. functionalized gold electrodes with the negatively charged 11 mercaptoundecanoic acid and then apply the LBL assembly of a positively charged redox polymer, poly, and the negatively charged GOx/SWCNTs for glucose sensor.
Liu et al. developed an amperometric glucose biosensor based on electrostatic assembly of GNPs/MWCNTs/GOx. Positively charged poly was used to connect them in a LBL pattern. The electrode showed an excellent electrocatalytic activity for glucose sensing at a relatively low potential. Xu et al. described an amperometric glucose biosensor based on an alternating electrostatic selfassembling GOx and dendrimer encapsulated Pt nanoparticles on MWCNTs. The excellent electrocatalytic activity of CNTs and Pt DENs toward H2O2 and special three dimensional structure of the enzyme electrode resulted in a low detection limit with a wide linear response range, a high sensitivity with a good precision, and an enhanced operational stability.
Shirsat et al. fabricated an amperometric glucose biosensor by applying a LBL assembly of SWCNTs and PPy multilayer film on a platinum coated with polyvinylidene fluoride membrane. GOx was immobilized on the film by cross linking through glutaraldehyde and a linear response range from 1 mM to 50 mM of glucose concentration with the sensitivity of 7.06 uA/mM was achieved. A glucose sensor based on the LBL assembly of functionalized MWCNTs and poly multilayer film was also suggested. This electrode showed a significant improvement of redox activity showing a synergic effect of excellent electron transfer capability of CNTs and PNR. Another type of glucose biosensor was constructed by immobilizing GOx onto the electrode surface using GA.

Glycyrrhizic acid present in the plant inhibits virus growth and inactivates virus particles. 5.1.2. Ocimum sanctum. O. sanctum, also known as Tulsi and Holy Basil, is an aromatic plant of the family Lamiaceae. The plant, as a whole, is a treasure house of potent compounds with its leaves, seeds, and roots, as well as flower being medicinally important and is considered divine by the Hindus. O. sanctum is considered E7080 to be an adaptogen par excellence. It harmonizes different processes in the body and is helpful in acclimatizing to stress. The main chemical constituents of O. sanctum are oleanolic acid, ursolic acid, rosmarinic acid, eugenol, carvacrol, linalool, and caryophyllene. The antiviral activity of eugenol has been reported. Ocimum extracts are used in ayurvedic remedies for common colds, headaches, stomach disorders, inflammation, heart disease, various forms of poisoning, and malaria.
Traditionally, O. sanctum is taken in many forms as herbal tea, dried powder, fresh leaf, or mixed with ghee. Essential oil extracted from Karpoora O. sanctum is mostly used for medicinal purposes and in herbal cosmetics, and is widely used in skin preparations due to its antimicrobial activity. Recent studies suggest that O. sanctum may be a COX 2 inhibitor, Epothilone A like many modern painkillers, due to its high concentration of eugenol. O. sanctum is reported to be an effective treatment for diabetes and high cholesterol. O. sanctum also shows promise for protection against radiation damage. O. sanctum leaves contain highest percentage of essential oils, infusion of which is given in malaria.
Juice of the leaves is taken internally and is very effective in skin diseases such as itches fungal infections. Fresh leaves also cure chronic fever and when mixed with honey and ginger juice, it is useful in cough and bronchitis. During the past decade the plant has been extensively investigated and has been shown to possess a range of biological activities such as antibacterial activity, antifungal activity, and antiviral activity. Nitric oxide production was induced by O. tenuiflorum extracts in stimulated peripheral blood mononuclear cells in vitro and the active component responsible for immunomodulatory action were identified. The extract was also used to stimulate the cells individually and in combination with mitogens as well. The antimicrobial properties of O. sanctum make it useful for the management of novel H1N1 flu.
5.1.3. Alium sativum. Alium sativum, also known as Lahsan and Garlic, belongs to family Alliaceae. A. sativum has been used throughout recorded chronicles for both culinary and medicinal purposes. It has a characteristic pungent, spicy flavor. A. sativum has been used for hundreds of years to treat fungal, parasitic, and viral infections, and has anti inflammatory properties that show promise for prevention of cardiovascular disease. It is known to kill influenza virus in vitro. Researchers are focusing on an extract of A. sativum called ajoene, which appears to protect CD cells from attack by HIV early in the viral life cycle. At low concentrations, the drug appears to have little toxicity, and its anti HIV activity is 45 times more powerful than the drug dextran sulfate. Ajoene is found only in fresh A. sativum and is not readily procurable.
