Webguanine (N7) Depurination. Removal of purines, strand breakae, and cleavage of the purine ring occur. Alkylating Agents MOA. Drugs start as prodrugs and become activated when a Cl atom is extracted, forming a carbonium ion. This ion is very electrophilic and will attack any pair of free electrons. This attack results in bonding between the drug ... WebAlkylating Agents. Alkylating agents (ATC code L01A) are highly reactive compounds that easily attach to DNA and cellular proteins. The primary mode of action for most alkylating drugs is via cross-linking of DNA strands. They can be classified as either monofunctional alkylating agents, implying reactions with only one strand of DNA, or ...
