Under the effect of a catalytic amount of Au(I) complex, 4-O-(2-cyclopropylethynyl)benzoyl-(epi)-podophyllotoxins, easily prepared via dehydrative condensation between (epi)-podophyllotoxin and ortho-cyclopropylethynylbenzoic acid, could efficiently coupl

A series of carbamate derivatives of 4′-demethylepipodophyllotoxin have been synthesized, and their cytotoxicities against several human cancer cell lines, including HeLa, A549, HCT-8, and HL-60 cells, evaluated. Some of these compounds exhibited higher levels of cytotoxicity than the anticancer drug etoposide. 4β-4′-Demethylepipodophyllotoxin 1-(4-nitrophenyl) piperazinyl carbamate (19) was found to be the most potent compound of those synthesized in the current study, and induced cell cycle arrest in the G2/M phase in HeLa cells, which was accompanied by apoptosis. Furthermore, this compound activated the expression of Bax, p53 and caspase-3 in HeLa cells, leading to changes in the conformation of calf thymus DNA from the B-form to a more compact C-form.
