Imp dehydrogenase activity
WitrynaIn enzyme pattern-targeted chemotherapy, tiazofurin inhibits IMP dehydrogenase activity in cancer cells and allopurinol-induced high serum hypoxanthine levels inhibit HGPRT activity ... IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of de novo GTP biosynthesis, is a promising target in antileukemic chemotherapy. WitrynaInosine monophosphate dehydrogenase (IMPDH) catalyzes an essential step in the de novo biosynthesis of guanine nucleotide, namely, the conversion of IMP to XMP. The depletion of the intracellular GTP and dGTP pools is the major event occurring in the cells exposed to the inhibitors such as mycophenolic acid.
