| Application: | Clofarabine has been used in a cell viability assay to analyze the sensitivity of the isogenic cell lines towards clofarabine. It is also used to study the interaction of anticancer drug clofarabine with human serum albumin and human α-1 acid glycoprotein. |
| Biochem/physiol Actions: | Clofarabine is a purine nucleoside antimetabolite. Clofarabine is toxic to nondividing lymphocytes and monocytes. |
| Biochem/physiol Actions: | Clofarabine is a second-generation nucleoside analog, used in cancer treatments. Clofarabine is metabolized to 5′-triphosphate and is known to block DNA synthesis. The human equilibrative nucleoside transporters (hENT1 and hENT2) and human concentrative nucleoside transporter (hCNT2 and hCNT3) mediates clofarabine transport into the cell. It also serves as a substrate for mitochondrial deoxyguanosine kinase. Clofarabine is an inhibitor of ribonucleotide reductase. It resists the phosphorolytic cleavage catalyzed by purine nucleoside phosphorylase of bacterias. Clofarabine also withstands deamination by adenosine deaminase. |
