Anticancer thiopyrano[2,3-d][1,3]thiazol-2-ones with norbornane moiety. Synthesis, cytotoxicity, physico-chemical properties, and computational studies
摘要:
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.

for synthesis of novel dispirooxindolecyclo[pyrrolo[1,2-c]thiazole-6,5'-thiazolidine] derivatives without any catalysts under ultrasonic condition has been developed. Combining with the advantages of sonochemistry, such as mild reaction conditions, good yield and short reaction times, we have made a progress on construction of novel disiproheterocyclic compounds via the 1,3-dipolarcycloaddition of

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
