Abstract
CTP synthase (CTPS) catalyzes the conversion of UTP to CTP and is a recognized target for the development of anticancer, antiviral, and antiprotozoal agents. Xanthine and related compounds inhibit CTPS activity (IC50 = 0.16–0.58 mM). The presence of an 8-oxo function (i.e., uric acids) enhances inhibition (IC50 = 0.060–0.121 mM). An intact purine ring with anionic character favors inhibition. In general, methylation of the purine does not significantly affect inhibition.
