Description: Ulodesine, also known as BCX4208, is a purine nucleoside phosphorylase (PNP) inhibitor in development as a once-daily oral, chronic treatment for gout. Ulodesine is currently being developed by Biocryst. Ulodesine acts upstream of xanthine oxidase in the purine metabolism pathway to reduce the production of serum uric acid (sUA). Ulodesine has an IC(50) of 0.5 nM to PNP. BCX-4208 is currently undergoing early clinical investigation in psoriasis and gout.
