title: Steroidal derivatives. Part 1: some novel steroidal thiosemicarbazones. Their synthesis, anticancer and endocrinological activities.
abstract: The synthesis of several novel thiosemicarbazone derivatives of steroids, including estrogens and androgens, is described. Evaluation of the products in P 388 Lymphocytic Leukemia indicated no anticancer activity. The endocrinological screening showed that estrogenicity is slightly reduced but not abolished in the thiosemicarbazones derived from estrone-3-methyl ether (compounds 1, 2 and 4). The androgenic activity of the thiosemicarbazones derived from testosterone (compounds 7--9) was more pronounced than that of testosterone. Among the same thiosemicarbazone derivatives 7--9, only o-tolyl derivative 8 exhibited anabolic activity.
