- BACKGROUND/AIM: Cancer is a leading cause of death. Hence, this study aimed at the optimization of niclosamide derivatives for the development of new potential anticancer agents.MATERIALS AND METHODS: Niclosamide derivatives were synthesized and tested against a panel of human cancer cells: MDA and MCF7 breast cancer cells, PC3 and DU-145 prostate cancer cells, Hela cervical cancer cells, and HL-60 acute promyelocytic leukemia cells. They were also tested in nuclear factor-ĸappa B (NFĸB), V-Ki-ras2 Kirsten rat sarcoma viral oncogene (KRAS), and mitochondria transmembrane potential (MTP) assays.RESULTS: N-(3,5-Bis(trifluoromethyl)phenyl)-5-chloro-2-hydroxybenzamide exhibited the most significant cytotoxicity against HL-60 cells, while 5-chloro-N-(2-chlorophenyl)-2-hydroxybenzamide was the most active in the NFĸB assay and 5-chloro-N-(3,5-difluorophenyl)-2-hydroxybenzamide in the MTP assay. 5-chloro-N-(2-chloro-4-(trifluoromethyl) phenyl)-2-hydroxybenzamide and 5-chloro-2-hydroxy-N-(4-hydroxyphenyl)benzamide inhibited both HL-60 cell proliferation and NFĸB.CONCLUSION: In-depth study of the most promising compounds is highly encouraged to further develop into potential anticancer agents those derivatives found to be significantly active.
