Synthesis and cytotoxicity evaluation of a novel justicidin G analogue and its phosphate ester

Abstract The novel justicidin G analogue 13 and its phosphate ester 15 were synthesized as potential anticancer agents in several steps starting from commercially available methyl gallate and veratraldehyde. The cytotoxicity of the intermediates was tested against HCT-8, BEL-7402, KETR3, HELA, BGC-823, KB and MCF-7 cell lines by the MTT test, and compound 15 exhibited significant cytotoxicity in HELA and KB cell lines.
