Clofarabine-5'-triphosphate trisodium is the trisodium salt form of Clofarabine-5'-triphosphate. Clofarabine-5'-triphosphate trisodium is the metabolite of Clofarabine by deoxycytidine kinase (dCK) phosphorylation. Clofarabine-5'-triphosphate trisodium exhibits cytotoxicity in cancer cells through inhibition of DNA synthesis and DNA repair.
