Summary: A series of new hybrid compounds containing 1,2,3-triazole and oxadiazolyl, Phthalimidyl or indolyl groups were synthesized. The reaction between the starting compound 5-phenyl-1-(aryl)-1H-1,2,3-triazole-4-carbohydrazides (5) and 5-nitrofuran-2-carboxylic acid (6) yielded 2-nitro-5-(5-phenyl-1-(aryl)-1H-1,2,3-triazol-4-yl)-1,3,4-oxadiazoles 7a-c in good yields. Treatment of 5 with phthalic anhydride (8) afforded N-(1,3-dioxoisoindolin-2-yl)-5-phenyl-1-(aryl)-1H-1,2,3-triazole-4-carboxamide 9a-d, while the reaction with isatin resulted in N'-(2-oxoindolin-3-ylidene)-5-phenyl-1-(aryl)-1H-1,2,3-triazole-4-carbohydrazides 11a-d in 88-90% yields. The chemical structures of the novel compounds were confirmed by NMR spectroscopy and single crystal x-ray diffraction. Some of the synthesized compounds showed promising antiproliferative activity against various human cancer cell lines (HCT-116, HepG2, and MCF-7). (c) 2022 Elsevier B.V. All rights reserved.
