MedKoo CAT#: 406727

CAS#: 297730-05-3

Description: VX-148 is a novel, uncompetitive IMPDH inhibitor with a K(i) value of 6 nM against IMPDH type II enzyme. VX-148 is slightly more potent than mycophenolic acid and VX-497 in inhibiting the proliferation of mitogen-stimulated primary human lymphocytes (IC(50) value of ~80 nM). The inhibitory activity of VX-148 is alleviated in the presence of exogenous guanosine. VX-148 does not inhibit proliferation of nonlymphoid cell types such as fibroblasts, indicating selectivity for inhibition of IMPDH activity. VX-148 is orally bioavailable in rats and mice; oral administration of VX-148 inhibits primary antibody response in mice in a dose-dependent manner with an ED(50) value of 38 mg/kg b.i.d. VX-148 significantly prolongs skin graft survival at 100 mg/kg b.i.d. in mice.
