A gene-directed enzyme pro-drug therapy (GDEPT) based on purine nucleoside phosphorylase (PNP), that converts the prodrug, fludarabine to 2-fluoroadenine, has been described, but studies are limited compared with other GDEPTs. We investigated the in vitro and in vivo efficacies of
Carbocyclic and acyclic nucleosides possessing 2-fluoroadenine, such as 2-fluoronoraristeromycin (6) and 2-fluoro-9-[(2S,3R)-2,3,4-trihydroxy-butyl-1-yl]adenine (8), were synthesized and their inhibitory activities against human and Plasmodium falciparum recombinant SAH hydrolase were investigated.
2-Fluoroadenine (F-Ade) is a metabolite of 9-beta-D-arabinofuranosyl-2-fluoroadenine (F-ara-A) that may be involved in the development of toxic side effects from this anticancer drug. The liberation of F-Ade from F-ara-A has been examined in different biological systems. Extracts of Escherichia coli

The production of isotopically labeled RNA remains critical to current NMR structural studies. One approach to obtain simple NMR spectra is to label with a nucleus that is not naturally occurring in RNA. Fluorine-19 can serve as a sensitive site-specific

A double mutant of human purine nucleoside phosphorylase (hDM) with the amino acid mutations Glu201Gln:Asn243Asp cleaves adenosine-based prodrugs to their corresponding cytotoxic drugs. When fused to an anti-tumor targeting component, hDM is targeted to tumor cells, where it effectively catalyzes
