Comparison of current alkylating agents with a homo-aza-steroidal ester for antineoplastic activity.

The modified steroidal alkylating agent, 17 beta-hydroxy-3-aza-A-homo-4 alpha-androsten-4-one-p-bis(2-chloroethyl)aminophenoxyacetate++ + has been tested against L1210 and P388 leukemias, and Lewis lung cancer, on DNA synthesis of EAT, L1210, P388, and BHK cell cultures, and on the induction of sister chromatid exchange. Comparable studies in vivo and in vitro were also done with p-bis(2-chloroethyl)aminophenoxyacetic acid, cyclophosphamide, melphalan, and chlorambucil.
