TARGETING PPAR-gamma TO DESIGN AND SYNTHESIZE ANTIDIABETIC THIAZOLIDINES

A series of thiazolidine derivatives were designed by docking into PPAR-y active site. The structure of target was obtained from the protein data bank (PDB ID P37231). A library of 200 molecules was prepared on random basis. Molecular docking studies were performed using VLife MDS 4.3 software. After molecular docking studies, the 4-substituted-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid N-[4-(2,4-dioxo-thiazolidin-5-ylidenemethyp-phenyl]-hydrazides (4a-4h) were selected for synthesis. The progress of reaction and purity of the synthesized compounds were monitored by TLC and melting point. Structures of title compounds were confirmed by elemental analysis, IR, H-1 NMR and mass spectral data. The antidiabetic activity of title compounds was performed using the Wistar rats by alloxan-induced method. The compounds have shown antidiabetic activity comparable with the standard drug pioglitazone. These findings suggest that potent antidiabetics can be generated by substituting nonpolar, electron withdrawing substituents at the fourth position of pyrimidine skeleton and hydrogen bond acceptor at the nitrogen of the thiazolidine nucleus, to inhibit peroxisome proliferator-activated receptor-gamma.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6118-51-0 help many people in the next few years. Application In Synthesis of exo-3,6-Epoxy-1,2,3,6-tetrahydrophthalic Anhydride.

Thiazolidin-2-cyanamides derivatives as novel potent Escherichia coli beta-glucuronidase inhibitors and their structure-inhibitory activity relationships

Gut microbial beta-glucuronidases have the ability to deconjugate glucuronides of some drugs, thus have been considered as an important drug target to alleviate the drug metabolites-induced gastrointestinal toxicity. In this study, thiazolidin-2-cyanamide derivatives containing 5-phenyl-2-furan moiety (1-13) were evaluated for inhibitory activity againstEscherichia coli beta-glucuronidase (EcGUS). All of them showed more potent inhibition than a commonly used positive control,d-saccharic acid 1,4-lactone, with the IC(50)values ranging from 1.2 mu M to 23.1 mu M. Inhibition kinetics studies indicated that compound1-3were competitive type inhibitors for EcGUS. Molecular docking studies were performed and predicted the potential molecular determinants for their potent inhibitory effects towards EcGUS. Structure-inhibitory activity relationship study revealed that chloro substitution on the phenyl moiety was essential for EcGUS inhibition, which would help researchers to design and develop more effective thiazolidin-2-cyanamide type inhibitors against EcGUS.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 29681-57-0, you can contact me at any time and look forward to more communication. SDS of cas: 29681-57-0.

Breslow Intermediates from a Thiazolin-2-ylidene and Fluorinated Aldehydes: XRD and Solution-Phase NMR Spectroscopic Characterization

The first generation and X-ray diffraction (XRD) analysis of a crystalline Breslow intermediate (BI) derived from a thiazolin-2-ylidene, that is, the aromatic heterocycle present in vitamin B-1, is reported. Key to success was the combined use of pentafluorobenzaldehyde and a thiazolin-2-ylidene carrying an enol-stabilizing dispersion energy donor as N-substituent. A so-called primary intermediate (PI) could be isolated in protonated form (pPI) as well and analyzed by XRD. Furthermore, the first stable BI derived from an aromatic thiazolin-2-ylidene and an aliphatic aldehyde (trifluoroacetaldehyde) was prepared and characterized by NMR spectroscopy in solution. When switching to a saturated thiazolidin-2-ylidene, reaction with pentafluorobenzaldehyde afforded a new BI in solution (NMR spectroscopy). Attempts to crystallize the latter BI resulted in the isolation of a novel thiazolidin-2-ylidene dimer that had undergone rearrangement to a hexahydro[1,4]-thiazino[3,2-b]-1,4-thiazine.

Preparation of thiazolidin-4-one derivatives using ZnO-NiO-NiFe(2)O(4)nano-composite system

The hydrothermal synthesis of ZnO-NiO-NiFe(2)O(4)nano-composite is reported. The sample was utilized to characterize via XRD, FE-SEM, EDS, FT-IR, UV-Vis, and BET techniques. The sample consisted of three different phases as ZnO (hexagonal), NiO (cubic), and NiFe2O4(cubic) with the average particle size as 34 nm and specific surface area, average pore diameter, and pore volume as 64.35 m(2) g(-1), 13.02 nm, and 0.201 cm(3) g(-1), respectively. Catalytic behavior of the nano-composite was investigated on the synthesis of thiazolidin-4-one derivatives under thermal and ultrasonic irradiation condition. Our results show that the catalytic activity of ZnO-NiO-NiFe(2)O(4)nano-composite is much higher than ZnO, NiO, and NiFe(2)O(4)metal oxides. All products were prepared in high yields with short reaction times. In addition, the catalyst was recovered for at least five times.

An interesting hybrid molecular framework comprising of benzylidenethiazolidin-4-one, chalcone and fibrate was designed and synthesized (BRF1-12) in order to develop safe and efficacious compounds for the treatment of dyslipidemia, and related complications such as atherosclerosis. The synthesized derivatives were characterized by Fourier transform infrared spectroscopy, mass, and nuclear magnetic resonance spectral studies and evaluated for their antihyperlipidemic potential, using in vivo and in silico methods. All the synthesized compounds exhibited promising antidyslipidemic activity comparable to, and sometimes better than that of, the standard drug-fenofibrate at the tested dose of 30 mg/kg body weight. The most active compounds of the series, BRF4 and BRF6, demonstrated significant antidyslipidemic profile by lowering low density lipoprotein cholesterol, very low density lipoprotein cholesterol, and triglyceride and increasing the level of high density lipoprotein cholesterol, thereby decreasing the atherogenic index. Overall, these effects of BRF4 and BRF6 were found to be more potent than fenofibrate, in lipid lowering activity and reducing atherogenic index. Structure-activity relationship studies conclusively established that the presence of N-acetic acid methyl ester at 3rd position of the thiazolidin-4-one nucleus, and a C-3 fibric acid moiety at benzene nucleus were instrumental for enhanced biological activity. The binding mode of benzylidenethiazolidin-4-one fibrate class of compounds, showing crucial hydrogen bonds and pi-pi stacking interactions with the key amino acid residues Phe118, His440, and Tyr464 at the active site of PPAR alpha receptor, was assessed by molecular docking studies.

Discovery of benzo[cd]indol-2-one and benzylidene-thiazolidine-2,4-dione as new classes of NLRP3 inflammasome inhibitors via ER-beta structure based virtual screening

The structure-guided virtual screening (VS) has proved to be successful strategy in identification of new scaffolds for biological targets. The overactivity of NLRP3 inflammasome has been implicated in variety of inflammatory diseases including Alzheimer’s disease. The up-regulation of estrogen-receptor beta (ER-beta) activity has been directly linked with inhibition of NLRP3 inflammasome activity. In the present study, we report discovery of new NLRP3 inflammasome inhibitors via ER-beta crystal structure (PDB: 5TOA) guided virtual screening of 20,000 compound library. For experimental validation, top 10 ligands were selected based on structure novelty, docking score, prime MMGB/SA binding affinity and interaction pattern analysis. Amongst the tested compounds, three thiazolidin-4-ones IIIM-1268, IIIM-1269 and IIIM-1270 and benzo[cd]indol-2-one IIIM-1266 have shown 73, 69, 75 and 77% suppression of IL-1 beta release in mouse macrophages (J774A.1 cells) at 10 mu M. Benzylidene-thiazolidine-2,4-diones IIIM-1268 and IIIM-1270 inhibited IL-1 beta release with IC50 of 2.3 and 3.5 mu M and also significantly decreased the protein expression level of mature form of IL-1 beta in western-blot analysis. IIIM-1266 and IIIM-1270 displayed bidentate H-bonding with Arg 346 and Glu 305 residues in the active site of ER-beta; and they also strongly occupied the ADP-binding site of NLRP3 protein. The results presented herein, indicate that ER-beta guided VS can be successfully used to identify new NLRP3 inflammasome inhibitors, which may have potential in the development of novel anti-Alzheimer agents.

Organocatalytic Enantioselective alpha-Amination of Thiazol-4-one-5-carboxylates with Azodicarboxylates

An effective method for the asymmetric synthesis of 5-hydrazinothiazol-4-one-5-carboxylates was developed. The tetrasubstituted chiral carbon center was generated by asymmetric amination of thiazol-4-one-5-carboxylate with azodicarboxylate catalyzed by a bifunctional squaramide-based (1R,2R)-cyclohexane-1,2-diamine backbone in good to excellent yields (40-96%) with high levels of enantioselectivity (92-98% ee). A representative transformation of the amination product to a biologically important 1,3,4-oxadiazol-2(3H)-one is achieved without any appreciable loss in enantioselectivity.
