title: [Synthesis of analogs of cephalotaxine esters and their antitumor activities].
abstract: Four analogs of cephalotaxine esters (C1Z, C2E, C3E, C4E) were synthesized. The ratio of the Z, E isomers of the side chain alpha, beta-unsaturated ester carboxylic acids is reported. The Z isomer was easy to transform to the E isomer. Compound C1Z showed significant activity of inducing cancer cell HL-60 differentiation. It also showed inhibitory activity on Leukemia L1210.
