Thiazolidine prodrugs as protective agents against gamma-radiation-induced toxicity and mutagenesis in V79 cells

Representatives of two classes of thiazolidine prodrug forms of the well-known radioprotective agents L-cysteine, cysteamine, and 2-[(aminopropyl)amino]ethanethiol (WR-1065) were synthesized by condensing the parent thiolamine with an appropriate carbonyl donor. Inherent toxicity of the prodrugs was assessed in V79 cells using a clonogenic survival assay. Protection against radiation-induced cell death was measured similarly after exposure to 0-8 Gy gamma (137Cs) radiation. Antimutagenic activity was determined at the hypoxanthine-guanine phosphoribosyltransferase (HGPRT) locus. All thiazolidine prodrugs exhibited less toxicity than their parent thiolamines, sometimes dramatically so. Protection against radiation-induced cell death was observed for the 2-alkylthiazolidine, 2(R,S)-D-ribo-(1?,2?,3?,4?-tetrahydroxybutyl) thiazolidine (RibCyst), which produced a protection factor at 8 Gy of 1.8; the cysteine analogue, 2(R,S)-D-ribo-(1?,2?,3?,4?-tetrahydroxybutyl) thiazolidine-4(R)-carboxylic acid (RibCys), was less active. RibCyst also exhibited excellent antimutational activity, rivaling that of WR-1065. The 2-oxothiazolidine analogues showed little activity in either determination under the conditions tested, perhaps due to their enhanced chemical and biochemical stability.

Acid-Catalyzed Synthesis of Thiazolidin-4-ones

A two-steps synthesis of thiazolidin-4-ones, from alpha-tetralone 6 or thiochroman-4-one 7, catalyzed by acids is described. The reactions of alpha-tetralone 6 or thiochroman-4-one 7, with substituted thiosemicarbazides, under AcOH or heteropolyacid (HPAs) catalysis afford thiosemicarbazones 8 and 9 in excellent yields. Condensations of the previous compounds 8 and 9 with alpha-bromoester, under sulfuric acid or heteropolyacid catalysis, yield the corresponding thiazolidin-4-ones 10 and 11.

Penultimate group effects in free radical telomerizations of acrylamides

The telomerization of several acrylamides, most containing chiral auxiliary groups, was investigated. The first-formed stereogenic center in the n = 2 telomer (the penultimate center) has a significant effect on the configuration of the second (ultimate) center in the product. The penultimate chiral center of oxazolidine-derived acrylamides directs the configuration of the ultimate center such that the erythro n = 2 product is preferred. Sultam-substituted acrylamides preferentially lead, on the other hand, to threo products or give products with little stereoselectivity.

Design, synthesis, and anticancer potential of the enzyme (PARP-1) inhibitor with computational studies of new triazole, thiazolidinone, – thieno [2, 3-d] pyrimidinones

Background: Thienopyrimidine, triazole and thiazolidinone derivatives have recently gained attention due to their effective pharmacological activities. They show antioxidant, antitumor, antimicrobial, antiviral, anti-inflammatory and analgesic properties. Objective: Synthesis of new ethyl 2-amino-4-isopropyl-5-methylthiophene-3-carboxylate (2) was used as a starting material to produce 2-mercapto-methylthienopyrimidinone (3), (4) and 2- hydrazinyl-methylthienopyrimidinone (5), through high yields and evaluating anticancer activities. Methods: A series of novel Schiff?s bases (6-9) were produced after treatment of (5) with aldehydes. Triazolopyrimidinones (6a, 7a, 8a, 9a) were produced from cyclization of benzylidene (6-9) using Br2 / AcOH or dry pyridine /Ac2O. Thiazolidinones (6b, 7b, 8b, 9b) were synthesized from benzylidene (6-9) with mercaptoacetic acid. Results: All the compounds were synthesized in good yields (55-85%) in a regularly actual system under mild condition. The new compounds have been established by means of diverse spectroscopic ways as IR, NMR and MS. The newly synthesized compounds were evaluated for their antiproliferative activity against the breast MCF-7 carcinoma cell line. Compound (7) showed promising anticancer activity with IC50 of 6.9 muM, and 40.8% of antioxidant effect as DPPH inhibition. Molecular docking of (7) showed deltaG values of-20.54 kcal/ mol and -25.60 kcal/ mol. Molecular dynamics simulation of (7) in complex with PARP-1 revealed RMSD of 3.00 a. Conclusion: The QSAR study confirmed the presence of a relationship between anticancer activity and subdivided surface area descriptors with coefficient r2 = 0.98 with high predictive power.

Recent advances in the discovery of HIF-1alpha-p300/CBP inhibitors as anti-cancer agents

Hypoxia-inducible factor-1 (HIF-1), a heterodimeric (containing alpha and beta subunits) transcription factor, is involved in hypoxia response pathway that regulates the expression of many tumor-related genes. The stabilized HIF-1 heterodimer couples to the general co-activators p300/CBP (CREB binding protein), forming an active transcription factor to initiate hypoxic responses. Inhibiting the transcription factor-coactivator HIF-1alpha-p300/CBP interaction represents an attractive approach for blocking hypoxia pathway in tumors. Recently, diverse HIF-1alpha-p300/CBP inhibitors have been designed and their anti-tumor activities have been evaluated. The developments of inhibitors of HIF-1alpha-p300/CBP are discussed in this review. An outline of structures and biological activities of these inhibitors can be traced, along with the approaches for inhibitors discovery. The challenges in identifying novel and selective potent inhibitors of HIF-1alpha-p300/CBP are also put forward.

Computational screening of drugbank database for novel cell cycle inhibitors

The cell cycle is governed by a family of proteins i.e. cyclin dependent kinases (CDKs) and their inhibitors (CDKIs) through activating and inactivating events. Cdks are heteromeric serine/threonine kinases that control progression through the cell cycle in concert with their regulatory subunits, the cyclins. CDK activity was found to increase in different types of human tumors as well as progression and/or invasiveness of some cancers such as breast, leukemia, and melanoma. Computer aided drug design was implemented to find novel compounds as possible CDK inhibitors. Screening of 1400 drugs from DrugBank database was carried out using Molegro software against various CDKs derived from Protein Data Bank. From the result, the best three drugs which exhibited high binding affinity against all targets are reported. The analysis against eight proteins resulted in 14 drugs and the top three drugs obtained are Olmesartan, Verteporfin and Atorvastatin.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 2682-49-7, you can also check out more blogs about2682-49-7

Glucosinolate hydrolysis products in the crucifer Barbarea vulgaris include a thiazolidine-2-one from a specific phenolic isomer as well as oxazolidine-2-thiones

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.
