Abstract

Valtrate, didrovaltrate and deoxido-didrovaltrate were compared for toxicity on cultured rat hepatoma cells (HTC strain) and for their effects on the synthesis of DNA and proteins.

Despite lacking the epoxide function in C8-C11 position in its molecular structure, deoxido-didrovaltrate has a similar cytotoxicity to didrovaltrate. The toxicity of both these drugs is two times lower than that of valtrate.

Incorporation tests with 3H-thymidine and 3H-leucine on cultured HTC cells revealed that a low dose of valtrate, rapidly and extensively inhibits the synthesis of both DNA and proteins.

Didrovaltrate and deoxido-didrovaltrate have the same effect, but at double the dose.
