title: Further studies on the antineoplastic activity of homo-aza-steroidal esters.
abstract: The modified steroidal alkylating agents, 17 beta-hydroxy-3-aza-A-homo-4 alpha-androsten-4- one(p-[bis(2-chloroethyl)amino]phenyl)butyrate(1),3 alpha-hydroxy- 13,17-seco-5 alpha- butyrate(2),3 beta-hydroxy-13,17-seco-5-androsten-17-oic- 13,17-lactam(p-[bis-(2-chloroethyl)amino]phenyl)butyrate(3) and and (p-[bis(2-chloroethyl)amino]phenyl)butyric acid(4) have been tested against L1210, P388, Ehrlich ascites tumors (EAT), Lewis lung (LL) carcinoma and adenocarcinoma CA-755. Of four compounds evaluated in L1210 leukemia, none displayed antileukemic activity. Almost all of the four compounds were more or less active against P388 leukemia. Compound 2 possesses a slight antitumor activity in EAT, while only compound 1 appears to be active in LL carcinoma. The antitumor activity of the three modified steroidal esters on adenocarcinoma CA-755 seems to be interesting.
