Chlorambucil is a nitrogen mustard alkylating agent [1]
Chlorambucil is a chemotherapy medication commonly used for the treatment of chronic lymphocytic leukemia (CLL). Chlorambucil forms intra- and inter-strand crosslinks in DNA, the latter of which prevents DNA replication and transcription leading to cell death [1]
In embryonic mouse limb buds directly exposed to chlorambucil at 1 ~ 2 μg/ml, the number of affected cells reached a plateau at 48 hr after treatment and decreased significantly by 72 hr, at which time exposure to a second dose of chlorambucil showed little or no effect. Chlorambucil-induced cell death was restricted almost exclusively to regions of undifferentiated mesenchymal cells [2].
In CLL patients, chlorambucil treatment (0.9 mg/kg given over 3 days) induced greater decrease in lymphocyte count against the control group [3]. In pharmacokinetic studies in tumor-bearing dogs receiving 4 mg/m2 metronomic chlorambucil, the LD50 and IC50 of chlorambucil were 270 μM and 114 μM for SF767 cells, and 390 μM and 96 μM for U87-MG cells, respectively. In human microvascular endothelial cells and human progenitor derived endothelial colony forming cells, the IC50 of chlorambucil was 0.53 μM and 145 μM, correspondingly [4].
