Elacytarabine | CP-4055 | CAS#188181-42-2

MedKoo Cat#: 201195 | Name: Elacytarabine

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Elacytarabine, also known as CP-4055, is the lipophilic 5'-elaidic acid ester of the deoxycytidine analog cytosine arabinoside (cytarabine; Ara-C) with potential antineoplastic activity. As a prodrug, CP-4055 is converted intracellularly into cytarabine triphosphate by deoxycytidine kinase and subsequently competes with cytidine for incorporation into DNA, thereby inhibiting DNA synthesis. Compared to cytarabine, CP-4055 shows increased cellular uptake and retention, resulting in increased activation by deoxycytidine kinase to cytarabine triphosphate, decreased deamination and deactivation by deoxycytidine deaminase, and increased inhibition of DNA synthesis. This agent also inhibits RNA synthesis, an effect not seen with cytarabine.
