This product is a pyrimidine anti-metabolite drug that mainly acts on cells in the S proliferation phase. It interferes with cell proliferation by inhibiting the synthesis of cell DNA. After entering the human body, cytarabine is phosphorylated by kinase and converted into cytarabine triphosphate and cytarabine diphosphate. The former can strongly inhibit the synthesis of DNA polymerase, and the latter can inhibit the conversion of cytidine diphosphate to deoxycytidine diphosphate, thereby inhibiting cell DNA polymerization and synthesis. This product is a cell cycle-specific drug, which is most sensitive to cells in the S proliferation phase, and has a weaker effect on inhibiting RNA and protein synthesis.
