Mechanism of action

ARA-C is a nucleoside analog that mimics cytidine and is phosphorylated intracellularly to its active triphosphate form. This active metabolite competes with natural deoxycytidine triphosphate for incorporation into DNA during replication. Once incorporated, it causes chain termination and prevents further DNA synthesis, triggering apoptosis in rapidly dividing cells, particularly hematopoietic malignancies.
