Abstract
Four new chemicals, the homo-aza-steroidal esters of m-N,N-bis(2-chloroethyl)aminocinnamic acid, originaly synthesized to be used as antineoplastic agents, were tested for their mutagenic activity in the Ames test. 3 beta-Hydroxy-13 alpha-amino-13,17-seco-5-androsten-17-oic-13,17- lactam ester (ACALE3) and 3 alpha-hydroxy-13 alpha-amino-13,17-seco-5 alpha-androstan-17-oic-13,17-lactam ester of m-N,N-bis(2-chloroethyl)aminocinnamic acid (ACALE4) were found to induce base-pair substitutions, causing dose-dependent increases in his+ revertants in strains TA100 and TA1535, while no dose-dependent relations were established when 3 beta-hydroxy-13 alpha-amino-13,17-seco-5 alpha-androstan-17-oic-13,17-lactam ester (ACALE1) and 17 beta-hydroxy-3-aza-A-homo-4 alpha-androsten-4-one ester of m-N,N-bis(2-chloroethyl)aminocinnamic acid (ACALE2) were tested. The presence of metabolic activation enzymes in the test system had no effect in his+ revertants in strains TA100 and TA1535. The chemicals tested although having the same alkylating moiety and a similar chemical structure exhibited different mutagenic activities.
