J. Ashby et al., SIMILAR ACTIVITY OF CHLORAMBUCIL AND ITS SPERMIDINE CONJUGATE IN THE MOUSE BONE-MARROW MICRONUCLEUS ASSAY, Mutagenesis, 9(4), 1994, pp. 391-392
The spermidine conjugate of the human carcinogen and cancer therapeuti
c agent chlorambucil has been evaluated in the mouse bone marrow micro
nucleus assay. It showed a similar level of activity to that of chlora
mbucil, indicating that the superior ability of the conjugate to cross
-link DNA in vitro is not expressed as enhanced genotoxicity in vivo.
