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.
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.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
