Xanthosine monophosphate is an intermediate in purine metabolism, formed from IMP, and forming GMP.

Clinical significance

Xanthylic acid can be used in quantitative measurements of the inosine monophosphate dehydrogenase enzyme activities in purine metabolism, as recommended to ensure optimal thiopurine therapy for children with acute lymphoblastic leukaemia (ALL).1
