The synthesis and the in vivo evaluation against leukemias P388 and L1210 of six new alkylating steroidal esters are described. The esteric derivatives incorporating the 17 beta-acetamido-B-lactamic steroidal skeleton exhibited increased antileukemic activity and lower toxicity, compared to the 17 beta-acetamido-7-keto analogs. Among the 17 beta-acetamido-B-lactamic steroidal esters, the most potent compound afforded four out of six cures in leukemia P388 and was measured to be almost non-toxic, producing significant low levels of toxicity.
