Antidiabetic activity of some synthesized 2-(substituted phenyl)-3-(naphthalen-1-yl)thiazolidin-4-ones

The title compounds (Tz(1-10)) were synthesized by the reaction of thioglycollic acid on Schiff’s bases (L1-10) formed with 1-naphthylamine and substituted benzaldehydes. These were characterized on the basis of IR, NMR, Mass spectral and elemental analyses. The compounds were then evaluated for their antidiabetic activity using streptozotocin induced diabetes method. On screening, compounds Tz(1), Tz(4), Tz(5) and Tz(6) exhibited good antidiabetic activity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 141-84-4, in my other articles. Safety of Rhodanine.

Synthesis of Novel Fluorine Compounds Substituted-4-thiazolidinones Derived from Rhodanine Drug as Highly Bioactive Probes

Aim and Objective: It is known that rhodanine drug has various biocidal activities. The aim of this work was to improve the structure of rhodanine drug via alkylation at N, S, and O- centers in addition to the introduction of fluorine atoms. The new fluorinated modified rhodanines 2-16 were evaluated as enzymatic probes for cellobiase activity produced by fungi and as CDK2 inhibitors of tumor cells. Materials and Methods: Novel fluorine substituted N-alkyl, S-alkyl and amino-rhodanines were obtained via Hydroxy methylation, Mannich reactions, chlorination and amination of 5-(4′-fluorophenylene)-2-thioxo-thiazolidin-4-one, and the enzymatic effects of cellobiase produced by fungi and /or CDK2 inhibition of tumor cells were evaluated. Results: Most of the targets were obtained in high yield and in the form of very pure crystals with characteristic colors. Only compounds 5, 8, 10, 13, and 14 exhibited a higher activity as cellobiase while compounds 2 and 5 showed a highly enzymatic effect on tumor cells. In addition, compounds 2 and 10 can be used as Olomoucine (standard referees). Conclusion: Various N, S and O-alkyl derivatives of fluorine-substituted rhodanines were prepared via a simple method and used as enzymatic probes for cellobiase activity produced by fungi and CDK2 inhibitors for tumor cells. The more bioactive compounds had rich fluorine atoms as p-fluorophenyl and p-fluorobenzoyl bearing N, S, O-alkyl rhodanine. The highly active compounds may be used as enzymatic materials for various biological transformations in the future.

5-Adamantan thiadiazole-based thiazolidinones as antimicrobial agents. Design, synthesis, molecular docking and evaluation

In continuation of our efforts to develop new compounds with antimicrobial properties we describe design, synthesis, molecular docking study and evaluation of antimicrobial activity of seventeen novel 2-{[5-(adamantan-1-yl)-1,3,4-thiadiazol-2-yl] imino}-5-arylidene-1,3-thiazolidin-4-ones. All compounds showed antibacterial activity against eight Gram positive and Gram negative bacterial species. Twelve out of seventeen compounds were more potent than streptomycin and all compounds exhibited higher potency than ampicillin. Compounds were also tested against three resistant bacterial strains: MRSA, P. aeruginosa and E. coll. The best antibacterial potential against ATCC and resistant strains was observed for compound 8 (2-{ [5-(adamantan-1yl)-1,3,4-thiadiazol-2-yl]-imino} 5 (4 nitrobenzylidene)-1,3thiazolidin-4-one). The most sensitive bacterium appeared to be S. typhimirium, followed by B. cereus while L. monocitogenes and M. flavus were the most resistant. Compounds were also tested for their antifungal activity against eight fungal species. All compounds exhibited antifungal activity better than the reference drugs bifonazole and ketokonazole (3-115 times). It was found that compound 8 appeared again to be the most potent. Molecular docking studies on E. toll MurB, MurA as well as C. albicans CYP 51 and dihydrofolate reductase were used for the prediction of mechanism of antibacterial and antifungal activities confirming the experimental results.

Development of quinoline-based hybrid as inhibitor of methionine aminopeptidase 1 fromLeishmania donovani

Methionine aminopeptidase 1 (MetAP1) is a target for drug discovery against many adversaries and a potential antileishmanial target for its role in N-terminal methionine processing. As an effort towards new inhibitor discovery against methionine aminopeptidase 1 fromLeishmania donovani(LdMetAP1), we have synthesized a series of quinoline-based hybrids, that is (Z)-5-((Z)-benzylidine)-2-(quinolin-3-ylimino)thiazolidin-4-ones (QYT-4a-i) whose in vitro screening led to the discovery of a novel inhibitor molecule (QYT-4h) againstLdMetAP1. The compound QYT-4h showed nearly 20-fold less potency for human MetAP1 and had drug-like features. Time-course kinetic assays suggested QYT-4h acting through a competitive mode by binding to the metal-activated catalytic site. Notably, QYT-4h was most potent against the physiologically relevant Mn(II) and Fe(II) supplemented forms ofLdMetAP1 and less potent against Co(II) supplemented form. Surface plasmon resonance and fluorescence spectroscopy demonstrated high affinity of QYT-4h forLdMetAP1. Through molecular modelling and docking studies, we found QYT-4h binding at theLdMetAP1 catalytic pocket occupying both the catalytic and substrate binding sites mostly with hydrogen bonding and hydrophobic interactions which provide structural basis for its promising potency. These results demonstrate the feasibility of employing small-molecule inhibitors for selective targeting ofLdMetAP1 which may find use to effectively eliminate leishmaniasis.

Spirobifluorene based small molecules as an alternative to traditional fullerene acceptors for organic solar cells

Four new three-dimensional (3D) acceptor-acceptor-donor (A-A-D) type of small molecule acceptors (Ml, M2, M3 and M4) were designed for better optoelectronic properties in organic solar cells. These molecules contain spirobifluorene as a 3D core unit, flanked with 2,1,3- benzothiadiazole (BT) units linked with the end-capped acceptor groups 2-(4-oxo-4,5-dihydrocyclopenta-b-thiophene-6-ylidene)malononitrile (M1), 2-(3-oxo-2,3-dihydro-1H-indene-1-indene-1-ylidene)malononitrile (M2), 2-(5,6-difluoro-3-oxo-2,3-dihydroindene-1-ylidene) malononitrile (M3) and 2-(5,6-dimethyl-3-oxo-2,3-dihydroindene-1-ylidene)malononitrile (M4). The optoelectronic properties of M1 -M4 were compared with the well-known reference molecule R, which has the same central BT-spirobifluorene-BT structure as Ml-M4 but is end-capped with the 2-(2-dicyanomethylene)-3-ethyl-4-oxo-thiazolidin-5-ylidenemethyl group. Among these molecules, M3 has the most appropriate frontier molecular orbital diagram for optoelectronic properties as deduced from MPW1PW91 calculations and also shows the maximum absorption peak at longest wavelength (569 nm) by TD-MPW1PW91 calculations with a polarizable continuum model for chloroform solution. These properties are due to the strong electron-withdrawing end-capped acceptor group which causes a red shift in the absorption spectrum. Computed reorganization energies indicate that the electron mobilities for M1 -M4 are higher compared to that of reference R.

Bis(benzofuran-thiazolidinone)s and bis(benzofuran-thiazinanone)s as inhibiting agents for chikungunya virus

There are currently still no approved antiviral drugs to treat or prevent chikungunya virus (CHIKV) infections despite the fact that this arbovirus continues to cause outbreaks in Africa, Asia, and South- and Central-America. Thus 20 new conjugated compounds in the families of bis(benzofuran-1,3-thiazolidin-4-one)s and bis(benzofuran-1,3-thiazinan-4-one)s were designed based on the structural features of suramin. These new compounds were synthesized by chemical methods and their structures were confirmed spectroscopically. In CPE reduction assays, six of these new bis-conjugates inhibited CHIKV replication in Vero E6 cells with EC50 in the range of 1.9-2.7 mu M and selectivity index values of 75 or higher. These results and compounds provide a starting point for further optimization, design, and synthesis of new antiviral agents for this (re)emerging disease. (C) 2017 Elsevier B.V.

Design, synthesis and characterization of novel quinacrine analogs that preferentially kill cancer over non-cancer cells through the down-regulation of Bcl-2 and up-regulation of Bax and Bad

Both quinacrine, which contains a 9-aminoacridine scaffold, and thiazolidin-4-one are promising anticancer leads. In an attempt to develop effective and potentially safe anticancer agents, we synthesized 23 novel hybrid compounds by linking the main structural unit of the 9-aminoacridine ring with the thiazolidin-4-one ring system, followed by examination of their anticancer effects against three human breast tumor cell lines and matching non-cancer cells. Most of the hybrid compounds showed good activities, and many of them possessed the preferential killing property against cancer over non-cancer cells. In particular, 343-(6-chloro-2-methoxy-acridin-9-ylamino)-propy1]-2-(2,6-difluoro-pheny1)-thiazolidin-4-one (11; VR118) effectively killed/inhibited proliferation of cancer cells at IC50 values in the range of 1.2. -2.4 mu M. Furthermore, unlike quinacrine or cisplatin, compound 11 showed strong selectivity for cancer cell killing, as it could kill cancer cells 7.6-fold (MDA-MB231 vs MCF10A) to 14.7-fold (MCF7 vs MCF10A) more effectively than matching non-cancer cells. Data from flow cytometry, TUNEL and Western blot assays showed that compound 11 kills cancer cells by apoptosis through the down-regulation of Bc1-2 (but not Bcl-X-L) survival protein and up-regulation of Bad and Bax pro-apoptotic proteins. Thus, compound 11 is a highly promising lead for an effective and potentially anticancer therapy. (C) 2017 Elsevier Masson SAS. All rights reserved.

In Vitro Effects of the Endocrine Disruptor p,p ‘-DDT on Human Follitropin Receptor

BACKGROUND: 1-chloro-4-[2,2,2-trichloro-1-(4-chlorophenyl) ethyl] benzene (p,p’-DDT) is a persistent environmental endocrine disruptor (ED). Several studies have shown an association between p,p’-DDT exposure and reproductive abnormalities. OBJECTIVES: To investigate the putative effects of p, p’-DDT on the human follitropin receptor (FSHR) function. METHODS AND RESULTS: We used Chinese hamster ovary (CHO) cells stably expressing human FSHR to investigate the impact of p,p’-DDT on FSHR activity and its interaction with the receptor. At a concentration of 5 mu M p, p’-DDT increased the maximum response of the FSHR to follitropin by 32 +/- 7.45%. However, 5 mu M p,p’-DDT decreased the basal activity and did not influence the maximal response of the closely related LH/hCG receptor to human chorionic gonadotropin (hCG). The potentiating effect of p,p’-DDT was specific for the FSHR. Moreover, in cells that did not express FSHR, p,p’-DDT had no effect on cAMP response. Thus, the potentiating effect of p,p’-DDT was dependent on the FSHR. In addition, p,p’-DDT increased the sensitivity of FSHR to hCG and to a low molecular weight agonist of the FSHR, 3-((5methyl)-2-(4-benzyloxyphenyl)- 5-{[2-[3-ethoxy-4-methoxy-phenyl)-ethylcarbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)benzamide (16a). Basal activity in response to p,p’-DDT and potentiation of the FSHR response to FSH by p,p’-DDT varied among FSHR mutants with altered transmembrane domains (TMDs), consistent with an effect of p,p’-DDT via TMD binding. This finding was corroborated by the results of simultaneously docking p, p’-DDT and 16a into the FSHR transmembrane bundle. CONCLUSION: p,p’-DDT acted as a positive allosteric modulator of the FSHR in our experimental model. These findings suggest that G protein-coupled receptors are additional targets of-endocrine disruptors.
