Synthesis and biological evaluation of novel 1-O- and 14-O-derivatives of oridonin as potential anticancer drug candidates.


PMID 18644718

Abstract

Novel 1-O- and 14-O-derivatives of oridonin were synthesized and biologically evaluated. All of the derivatives exhibited stronger cytotoxicity against six cancer cell lines (BGC-7901, SW-480, HL-60, BEL-7402, A549, and B16) than oridonin in vitro, and some of them were more potent than oridonin and cyclophosphamide in vivo. Compounds Ib and IIg were the most potent with the IC(50) values of 0.84 microM for Ib in HL-60 cell and 1.00 microM for IIg in BEL-7402 cell.
