Dược Lực Học :
CP-4055 is a fatty acid derivative of cytarabine, an approved cytotoxic cancer drug. Cytarabine has limitations such as minimal uptake in solid tumours and is only used to treat leukaemia. CP-4055 is designed to overcome this limitation and has shown considerable uptake in solid tumour cells. CP-4055 is a patented new chemical entity of the nucleoside analog class, with improved biological properties and the potential to treat solid tumours such as non-small cell lung cancer, malignant melanoma and ovarian cancer.

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.
Chỉ Định :
Investigated for use/treatment in leukemia (unspecified) and melanoma.
