Peldesine (BCX 34) dihydrochloride is a potent, competitive, reversible, and orally active inhibitor of purine nucleoside phosphorylase (PNP), exhibiting IC50 values of 36 nM, 5 nM, and 32 nM against human, rat, and mouse red blood cell (RBC) PNP, respectively. Additionally, it acts as an inhibitor of T-cell proliferation with an IC50 of 800 nM. This compound shows promise for research into cutaneous T-cell lymphoma, psoriasis, and HIV infection [1] [2] [3] [4].
