alkylating drug

Quick Reference

A cytotoxic drug that damages DNA: the addition of alkyl groups to guanine can lead to fragmentation during frustrated repair; nucleotides may be cross-bridged, blocking strand separation; mispairing can cause mutation during replication. There are six groups of alkylating agents: nitrogen mustards, ethylenimes, alkylsulphonates, triazenes, piperazines, and nitrosureas. Examples include cyclophosphamide, dacarbazine, ifosfamide, procarbazine, and temozolomide.
