compounds were evaluated for their preliminary in vitro antimicrobial and cytotoxic activities. The investigation of antimicrobialactivity profile revealed that compounds 4d, 4f, 4g, and 4h exhibited marked activity against S. aureus and E. faecalis as compared with the standard while compounds 4d and 4h exhibited good antifungal activities against C. albicans, A. flavus, A. niger and C. neoformans

A simple green synthesis of (<i>Z</i>)-5-arylmethylene-4- thioxothiazolidines and thiopyrano[2,3-<i>d</i>]thiazolidine-2-thiones in PEG-400 under catalyst-free conditions
A series of novel 9-substituted-3,7-dithia-5-azatetracyclo[9.2.1.0(2,10).O-4,O-8]tetradecen-4(8)-ones-6 have been synthesized by a stereoselective hetero-Diels-Alder reaction of 5-ylidene-4-thioxo-2-thiazolidone derivatives with norbornene-2. All the compounds have been evaluated for antitumor activity in in vitro human tumor cell lines, and 10 of them possessed significant and selective cytotoxicity (MGM logGI(50) similar to -4.17 to -4.98, for individual cell lines logGI(50) up to -8). COMPARE analyses of differential growth inhibition patterns of compounds at the GI(50) level showed high correlations with some of the antitubulin agents. The lipophilicity of the compounds was studied by RP-TLC and found to correlate well with calculated log P values. Docking and structure-activity relationship studies produced seven QSAR models with 2 or 3 variables, with correlation coefficients r(2) > 0.9 and leave-one-out cross-validation correlation coefficients, q(2) > 0.8.
