Webthe literature, these are described as noncompetitive inhibitors (16). AXSP0056BS (cpd-1) was identified as an allosteric GCH1 inhibitor in an enzymatic assay with half maximal inhibitory concentration (IC50) values of 4 μM. The 8-oxo-GTP, a tightly binding, substrate analog GCH1 inhibitor, and 7-deaza-GTP, a WebGTP cyclohydrolase I. GTP cyclohydrolase I ( GTPCH) ( EC 3.5.4.16) is a member of the GTP cyclohydrolase family of enzymes. GTPCH is part of the folate and biopterin biosynthesis pathways. It is responsible for the hydrolysis of guanosine triphosphate (GTP) to form 7,8-dihydroneopterin triphosphate (7,8-DHNP-3'-TP, 7,8-NH 2 -3'-TP).
