III. Mechanism
- First-generation platinum based, alkylating Antineoplastic Agent
- Inorganic, water based compund
- Derived drugs include Carboplatin
- Components
- Platinum atom
- Ammonia groups (2)
- Activated via hydrolysis intracellularly to highly reactive, charged platinum complexes
- Binds DNA (e.g. GC rich regions)
- Results in DNA cross-links
- Results in cell growth inhibition (G2 Cell Cycle arrest), apoptosis and cell death
- Unique features
- Penetrates Testes barrier
- Partially penetrates blood brain barrier
