highly efficient method for the synthesis of 2-imino-4-(trifluoromethyl)thiazolidin-4-ol derivatives has been achieved by the one-pot, three-componentreactions of primary amines, aryl isothiocyanates, and 3-bromo-1,1,1-trifluoropropanone. The reactions go via symmetrical and unsymmetrical thiourea intermediates. Subsequent reactions of the products allow the synthesis of various scaffolds, including

in, we report a novel series of adamantyl/cycloheptyl indoleamide derivatives bearing sulfonamide and triazole pharmacophores adopting different chemical modifications and evaluated them for antiplasmodial activity in vitro. Among all the indoleamides, compounds 22, 24, 26 and 30 with sulfonamide pharmacophore showed promising activity with IC50 of 1.87, 1.93, 2.00, 2.17 μM against CQ sensitive Pf3D7

isoxazole-linked benzothiazole/benzoxazole derivatives were synthesized and evaluated for their anticancer activity against human cancer cell lines, such as HeLa (cervical), and A549 (lung) cell lines, with HEK-293 cell line used as a control. Among them, conjugates 8a, 8f, 13g, 13h and 13j displayed significant cytotoxic activity against human cancer cell lines. Furthermore, these active conjugates induced

A new series of fluoro 1,2,3-triazole tagged amino bis (benzothiazole) derivatives 8, 9 were prepared starting from 2-amino benzothiazole in four steps via amination, cyclization, alkylation followed by reaction with various azides under sharpless conditions through click chemistry approach. All newly synthesized compounds were screened for their antimicrobial and cytotoxic activity against four human cancer cell lines (U937, THP-1, Colo205, and A549), and promising compounds have been identified.
