Synthesis, molecular modeling, selective aldose reductase inhibition and hypoglycemic activity of novel meglitinides

In the present study, a novel generation of selective aldose reductase ALR2 inhibitors with significant hypoglycemic activities was designed and modulated based on rhodanine scaffold joined to an acetamide linker in between two lipophilic moieties. The synthesis of the novel compounds was accomplished throughout simple chemical pathways. Molecular docking was performed on B-cell membrane protein SUR1, aldehyde reductase ALR1 and aldose reductase ALR2 active sites. Compounds 10B, 11B, 12B, 15C, 16C, 26F and 27F displayed the highest hypoglycemic activities with 80.7, 85.2, 87, 82.3, 83.5, 81.4 and 85.3% reduction in blood glucose levels, respectively. They were more potent than the standard hypoglycemic agent repaglinide with 65.4% reduction in blood glucose level. Compounds 12B and 15C with IC50 0.29 and 0.35 μM were more potent than the standard ALR2 inhibitor epalrestat with IC50 0.40 μM. They were selective towards ALR2 over ALR1 134 and 116 folds, respectively. Molecular docking studies matched with the in-vitro and in-vivo results to elucidate the dual activities of both compounds 12B and 15C as potent antagonists for ALR2 over ALR1 and good agonists for the SUR1 protein.

Synthesis, in-vitro cytotoxicity and antimicrobial evaluations of some novel thiazole based heterocycles

Condensation of rhodanine (1) with pyrazol-3(2H)-one derivatives (2a-f) gave 5-substituted-2-thioxo-1,3- thiazolidin-4-one derivatives (3a-f). Reaction of compound (1) with 2-arylmethylidene-malononitrile (4a-d) yielded the unexpected derivatives (5a-d). The latter compounds were subjected to cyclization reactions with malononitrile under different basic conditions, hydroxylamine hydrochloride and/or thiourea to furnish the fused thiazole derivatives (6a-d) and (8-10a-d). Coupling of (1) with diazotized aromatic amines (11a-c) in pyridine afforded the arylhydrazones (12a-c). Fusion of latter compounds with malononitrile afforded the thiazolopyridazine derivatives (13a-c). The structures of the newly synthesized compounds were elucidated via spectral data and elemental analyses. The in-vitro cytotoxic activity of compounds (3a-f) against the cell line MCF-7 was evaluated. Also, the synthesized products were investigated for their antibacterial and antifungal activities against six standard organisms including the G- bacteria, Staphylococcus aureus and Bacillus subtilis, G+ bacteria, Escherichia coli and Proteus vulgaris in addition to fungi, Candida albicans and Aspergillus flavus.

Introducing broadened antibacterial activity to rhodanine derivatives targeting enoyl-acyl carrier protein reductase

Broadened antibacterial activity was introduced to rhodanine derivatives targeting Mycobacterial tuberculosis enoyl-acyl carrier protein reductase (Mtb InhA) by recruiting feature of xacins to bring DNA Gyrase B inhibitory capability. This is significant for preventing further bacterial injections in the tuberculosis treatment. The most potent compound Cy14 suggested comparable bioactivity (IC50=3.18μM for Mtb InhA; IC50=10nM for DNA Gyrase B) with positive controls. Structure–activity relationship discussion and molecular docking model revealed the significance of rhodanine moiety and derived methoxyl on meta-position, pointing out orientations for future modification.

Solid acid TS-1 catalyst: an efficient catalyst in Knoevenagel condensation for the synthesis of 5-arylidene-2,4-thiazolidinediones/Rhodanines in aqueous medium

Abstract: TS-1 zeolite was prepared for the synthesis of 5-arylidene-2,4-thiazolidinediones/Rhodanines in aqueous medium by incorporating titanium(IV) cations in a silicate-1 framework using hydrothermal treatment and characterized by using XRD, EDX, BET, FT-IR and SEM techniques. The catalytic activity of the catalyst was tested for Knoevenagel condensation reaction. The condensation of active ethylene 2,4-thiazolidinedione with substituted aryl aldehydes under aqueous medium at 90?°C afforded the corresponding product in excellent yield up to 92% within 30?min. The present method offers several advantages over the reported methods such as easy separation of catalyst, simple work-up procedure, and an excellent yield of desired product. Furthermore, the catalyst could be reused without significant loss in activity. Graphical abstract: [Figure not available: see fulltext.]

Green synthesis of 5 arylidene-2,4-thiazolidinedione, 5-benzylidene rhodanine and dihydrothiophene derivatives catalyzed by hydrated ionic liquid tetrabutylammonium hydroxide in aqueous medium

An efficient synthesis of 5 arylidene-2,4-thiazolidinediones and 5-benzylidene rhodanines by the Knoevenagel condensation of 2,4- thiazolidinedione or rhodanine with aromatic aldehydes was studied. It proceeded smoothly in the presence of tetrabutylammonium hydroxide/H2O-EtOH to afford the corresponding products in high yields at 50C. Also, a series of dihydrothiophene derivatives were synthesized via the four-component reaction of aldehyde, malonitrile, 2,4-thiazolidinedione, and piperidine in the presence of Bu4NOH as a basic ionic liquid in aqueous medium. This new method offers several advantages, such as excellent yields, short reaction times, and simple procedure(Equation presented). 2013

Urea/thiourea catalyzed, solvent-free synthesis of 5-arylidenethiazolidine- 2,4-diones and 5-arylidene-2-thioxothiazolidin-4-ones

An efficient and organo-catalyzed method has been developed for the synthesis of 5-arylidenethiazolidine-2,4-diones and 5-arylidene-2- thioxothiazolidin-4-ones via Knoevenagel condensation of arylaldehydes 1 and 2,4-thiazolidinedione 2a/2-thioxothiazolidin-4-one 2b under mild conditions. Urea-adduct 4 and azomethine 5 also afford arylidene-products 3 by reacting with 2a-b via addition-elimination reaction. This protocol has the features of use of inexpensive, ecofriendly readily available, effective catalyst system viz. urea/thiourea, avoidance of volatile solvents, excellent yield and simple work-up procedure.
