Additional information

ZK 5180 (androstonolone acetate) did not show a mutagenic potential in a bacterial reverse mutation assay (Ames test in S. typhimurium strains TA98, TA 100, TA 1538, TA 1535 and TA1537) up to the highest tested concentration of 2.5 mg/plate (at which precipitation of test compound and cytotoxicity were observed) in the absence or presence of extrinsic metabolic activation (liver S9 mix from Aroclor 1254 -treated rats).
