Derivatives of the thiazolidine-2,4-dione core represent a heterocyclic class with several correlated properties. In this context, the synthesis of structural analogues of these bioactive substances becomes attractive in the field of medicinal chemistry. These analogues act as antimicrobial agents against Gram-positives pathogens. The present work aimed to synthesize 10 different derivatives of 5-arylidene-thiazolidine-2,4-dione, employing urea as the catalyst in a solvent-free reaction medium, with yields that ranged from 45 to 99percent. The compounds obtained were submitted to an antimicrobial assay against S. aureus ATCC 29213. Two compounds presented minimum inhibitory concentration of 62.5 and 32.5 μg mL-1 and minimum bactericidal concentration -1, demonstrating their antibacterial potential. Principal component analysis was carried out to discriminate the compounds in active and inactive classes. Four geometric and electronic molecular descriptors were required to completely discriminate the compounds. The selected descriptors can guide us in designing new 5-arylidene-thiazolidine-2,4-dione derivatives with enhanced activity.

experimental part, p. 5388 - 5391 (2012/09/22)
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.
