Enzyme essential: Feeding studies with Dreschlera ravenelii show that labeled dihydroisocoumarin 1 is metabolized into monocerin (2) in exceptionally high levels. These results provide evidence for the role of 1 as the first enzyme-free intermediate in the monocerin biosynthesis pathway and, thus, as the final product of the polyketide synthase (PKS) catalyzed part of the pathway. Compound 1 may therefore be of use in further studies to isolate and sequence the monocerin PKS gene.

Two isomeric phenolic glucosinolates, m- and p-hydroxyl derivatives of epiglucobarbarin [(R)-2-hydroxy-2-phenylethylglucosinolate], co-occur in an eastern chemotype (P-type) of the crucifer Barbarea vulgaris along with epiglucobarbarin itself. Levels of the phenolic derivatives in B. vulgaris were low in summer but higher during fall and winter, allowing isolation of all three glucosinolates. Hydrolysis in vitro, catalyzed by Sinapis alba myrosinase at near neutral pH, resulted in expectable oxazolidine-2-thione type hydrolysis products of epiglucobarbarin and its m-hydroxyl derivative. In contrast, a thiazolidine-2-one type product was formed in vitro from p-hydroxy epiglucobarbarin and characterized by UV, IR, MS/MS and 2D NMR. Maceration of leaf material resulted in disappearance of the glucosinolates and formation of the same oxazolidine-2-thione and thiazolidine-2-one products as found in vitro. The detected amounts were comparable to initial amounts of precursor glucosinolates. The corresponding oxazolidine-2-thione type product was also detected quantitatively from glucobarbarin in foliage of a western genotype (G-type). We suggest that p-hydroxy epiglucobarbarin is initially converted into the conventional oxazolidine-2-thione, which would further rearrange to a thiazolidine-2-one due to the activating effect of the p-hydroxyl group. We conclude that a subtle difference between isomeric phenolic glucosinolates results in significantly different natural hydrolysis products.

In a article, 2682-49-7, molcular formula is C3H5NOS, introducing its new discovery.

A series of four compounds which contain thiazolidine-4-one ring were synthesized and preliminarily assessed as anti-inflammatory agents with anticipated selectivity against COX-2 enzyme. The synthesized compounds structures have been recognised according to their spectral FT-IR and 1H NMR data. GOLD software was used to perform molecular docking study. The crystallographic structure of the molecular target cyclo-oxygenase enzyme-2 (COX-2) was taken from PDB database however, the celecoxib and naproxen were selected as a positive controls. The docking results of the newly synthesized compounds shown that they can enter the substrate-binding area of the active site .The compound (Ia) showed the highest PLP fitness,while compound (Ic) appeared to have the lowest binding ability compared to celecoxib which may be due to the presence of para nitro group that deactivates the ring system. Whereas In vivo acute anti-inflammatory effects of the synthesized compounds were evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant decrease in the paw edema with respect to the effect of propylene glycol 50%v/v (control group). Compounds Ia,b,d showed potent anti-inflammatory effect than naproxen (50mg/kg, i.p.) at 180 min., while compound Ic exhibited lower anti-inflammatory effect.

Bromodomain-containing protein 4 (BRD4) is a member of the bromodomain and extra-terminal domain (BET) family of proteins. It epigentically regulates the transcription of growth-promoting genes and has become an attractive target for the development of anticancer and anti-inflammatory agents. In the current study, we performed an in silico screening of a small-molecule chemical library against the acetyl?lysine binding site of the first bromodomain (BD1) in BRD4 protein. Potential inhibitors identified through virtual screening were further studied through molecular dynamics simulations, water entrapment analysis and Molecular Mechanics (MM)/Poisson?Boltzmann surface area (PBSA) binding free energy calculations. Many of the identified compounds exhibit better G-score (?11.64 kcal?mol?1 to ?10.31 kcal?mol?1) and predicted binding affinity (?9.66 kcal?mol?1 to ?6.63 kcal?mol?1) values towards BRD4-BD1 than that of the reference compound (+)-JQ1. Molecular dynamics simulation studies show that in free-form BRD4 the reported conserved water molecules are not retained at their specific positoins due to flexibiliy in the ZA-loop. In BRD4?ligand complexes the number and positions of conserved water molecules depends on the bound ligand. Identified potential inhibitors bind stably at the acetyl?lysine binding pocket of BRD4 and form direct and water-mediated hydrogen bonds with higher occupancy which may contribute to ligand specificity towards BRD4-BD1. Further, through MM/PBSA we calculated the binding free energies of selected compounds, which shows that they have comparable energies to that of (+)-JQ1, while NSC744713 shows better binding free energy.

The increasing incidence of microbial resistance and newly emerging pathogens have become a serious challenge for public health. More and more efforts have been directed to the development of new antimicrobial agents with distinct mechanisms from the well-known classes of clinical drugs. The extensive clinical utilization of azole-based medicinal drugs has evoked numerous attentions, and their researches and developments have been a quite rapid developing and active highlight topic with an infinite space. Consideration of our researches on azole compounds and other literature in recent three years, this review scientifically reviewed the new progress of azole derivatives as antibacterial, antifungal, antitubercular and antiviral agents, including mono-nitrogen azoles (oxazoles, thiazoles and carbazoles), bis-nitrogen azoles (imidazoles, pyrazoles and benzimidazoles) and tri-nitrogen azoles (triazoles and benzotriazoles) as well as tetrazole derivatives. It was hoped that this review would be helpful for the design and development of highly efficient azole derivatives with high bioactivity and low toxicity.

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine “pro-drug” L-2-oxothiazolidine-4-carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

There is considerable interest in discovering drugs with the potential to protect inner ear hair cells (HCs) from damage. One means of discovery is to screen compound libraries. Excellent screening protocols have been developed employing cell lines derived from the cochlea and zebrafish larvae. However, these do not address the differentiated mammalian hair cell. We have developed a screening method employing micro-explants of the mammalian organ of Corti (oC) to identify compounds with the ability to influence aminoglycoside-induced HC loss. The assay is based on short segments of the neonatal mouse oC, containing ~80 HCs which selectively express green fluorescent protein (GFP). This allows the screening of hundreds of potential protectants in an assay that includes both inner and outer HCs. This review article describes various screening methods, including the micro-explant assay. In addition, two micro-explant screening studies in which antioxidant and kinase inhibitor libraries were evaluated are reviewed. The results from these screens are related to current models of HC damage and protection.
