Synthesis of Some C-5 Substituted 4-Phenylimino-Thiazolidin-2-Ones as Possible Anti-Inflammatory Agents

Based on the Knoevenagel condensation, nitrosation, and azo coupling reactions, the synthesis of some C-5 substituted 4-phenylimino-thiazolidin-2-ones was carried out. The chemical structures of the synthesized products have been determined by H-1 NMR spectroscopy and elemental analysis.

An expedient synthesis of new imino-thiazolidinone grafted dispiro-pyrrolidine-oxindole/indeno hybrids via a multicomponent [3+2] cycloaddition reaction in a deep eutectic solvent

An expedient, one-pot regio- and stereo-selective synthesis of new imino-thiazolidinone grafted dispiro-pyrrolidine hybrids has been accomplished successfully by a green and sustainable method. The synthesis included a three component [3+2] cycloaddition reaction of 2-(arylimino)thiazolidin-5-ylidenes, substituted isatin/ninhydrin and sarcosine using choline chloride (ChCl) : urea (1 : 2) as a deep eutectic solvent (DES) in a single step. Among the variety of reaction conditions, the utilization of choline chloride : urea (1 : 2) at 80 degrees C was found to be the most effective reaction condition to achieve desired dispiropyrrolidines in excellent yield with high regio- and stereo-selectivity. This method is operationally simple with cleaner conversion to afford the target compounds in short reaction times and avoids the use of environmentally hazardous solvents, which make this globally putative. Moreover, the ChCl : urea (1 : 2) can be reused for over three repeated cycles without any noteworthy loss of activity.

The present paper is designed to explore the potential of an important class of heterocycles coumarinylthiazolyl iminothiazolidinone to inhibit jack bean urease. The final products 6a-j were prepared by condensation of substituted aldehydes with intermediate 5 in sodium methoxide/methanol mixture. The synthesized compounds were characterized by their FTIR, H-1, C-13 NMR and mass spectral data. The synthesized coumarinylthiazolyl iminothiazolidinone hybrids 6 a-j were evaluated for their potential to inhibit urease activity. All the synthesized derivatives showed remarkable inhibitory activity with IC50 ranging 8 to 34 nM, while IC50 of standard thiourea is 18.5 nM. The compound 5-(2,4-Dichlorobenzylidene)-2-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl imino) thiazolidin-4-one 6 h bearing 2,4-di-chloro substituted phenyl ring exhibited excellent activity with IC50 value 8 nM. In silico molecular docking studies was performed against urease enzyme PDBID 4H9 M and predicted possible binding modes in catalytic site for these active compounds. The thiazole nitrogen in compound 6 h formed a strong hydrogen bonding interaction with side chain Gln635 having distance 2.01 angstrom and rest part of this inhibitor is present close to Val640. The most potent derivative 6 h have highest binding affinity with binding energy -6.178 kcal/mol. It is concluded based upon our results that 6 a and 6 h are most promising compounds from this series and provide a basis for rationale design of most potent urease inhibitors.
