Anti Cancer Drugs Mechanism of Action- Lecture Part 1

Anti Cancer Drug Mechanism Part 1-Alkylating Agents & Antimetabolite

Alkylating agents are reactive to DNA and cellular proteins and the primary mode of action is mostly through cross-linking of DNA strands, inhibiting replication of DNA and transcription of RNA. Some antimetabolites are structural analogs of normal molecular essentials for cell growth. After intaking into cells the analogues change to substances to interfere with DNA or RNA synthesis.
