Mechanism of Action
Gemcitabine is a synthetic pyrimidine nucleoside and cytarabine analogue which is metabolised intracellularly to active diphosphate and triphosphate nucleosides. It inhibits DNA synthesis by inhibiting DNA polymerase and ribonucleotide reductase. It also induces apoptosis and is primarily active against cells in the S-phase, but may also arrest cells at the G1-S border.
