Abstract
A new series of novel substituted 3,4-dihydronaphthalene incorporated to benzo[h]quinoline, benzo[g]indazole, thiazolidin-4-one, pyrazolo[3,4-d]thiazol and thiazolo[4,5-b]pyridine ring systems were synthesized and evaluated for their cytotoxicity against selected human cancer cell lines. Some of the tested compounds exhibited promising carcinoma growth inhibition. The detailed synthesis, spectroscopic data and biological activities of the tested compounds were reported.
