Description

Application

2-Fluoroadenine-9-β-D-arabinofuranoside (F-ara-A) has been used:

• to assess its interaction with kinase inhibitor UCN-01 in human leukemia cells (U937 and HL-60) and primary patient samples
• to assess its influence on endothelial cells by apoptosis assay and human microvascular endothelial cells (HMECs) by cytotoxicity assay
• in comparative cytotoxicity studies with Alemtuzumab CDC in 17p13- chronic lymphocytic leukemia (CLL) patients

Biochem/physiol Actions

Fludarabine (the 5′-phosphate) is a prodrug that is converted to F-ara-A, which enters cells and accumulates primarily as the 5′-triphosphate. F-ara-A interferes with DNA synthesis and repair and induces apoptosis of cancer cells.

Fludarabine (the 5′-phosphate) is a prodrug that is converted to F-ara-A, which enters cells and accumulates primarily as the 5′-triphosphate. F-ara-A interferes with DNA synthesis and repair and induces apoptosis of cancer cells. F-ara-A also strongly inhibits DNA methylation, particularly methylation of cytosine in CpG dinucleotide sequences.

Disclaimer

The name fludarabine refers to 9-β-D-arabinofuranosyl-2-fluoroadenine 5′-phosphate, but is sometimes erroneously used for this compound, which lacks the phosphate.
