Abstract Cyclophosphamide (CO) and two of its known metabolites, 4-hydroxycyclophosphamide (4-OHCP) and phosphoramide mustard (PAM), were analyzed for their ability to induce sister chromatid exchanges (SCEs) in mouse peripheral blood lymphocytes (PBLs) in vitro and in vivo. It is concluded that at equimolar concentrations, CP is a more potent SCE inducer in vivo than PAM and that PAM and 4-OHCP induce equal numbers of SCEs in a dose-dependent manner. The present study also shows that these metabolites of CP are more potent SCE inducers than CP itself in vitro. This relationship might be explained by the differences in pharmacokinetics of these compounds. (Copyright (c) 1989 Elsevier Science Publishers. B.V. (Biomedical Division).)
