Mycophenolicacid sodium is a potent uncompetitive inhibitor of inosine monophosphate dehydrogenase (IMPDH), exhibiting an EC50 of 0.24 μM. It has broad antiviral activity against RNA viruses, including influenza. Additionally, mycophenolicacid sodium possesses immunosuppressive properties and exerts antiangiogenic and antitumor effects [1][2].
Methyl mycophenolate can be used to synthesize mycophenolicacid β-D-glucuronide and phenolic glycosides. (E Z)-Methyl mycophenolate is a racemic compound of (Z)-Methyl mycophenolate and (E)-Methyl mycophenolate isomers. Methyl mycophenolate is a methyl e
VX-148是一种新型、非竞争性的IMPDH抑制剂,对IMPDH II型酶具有6 nM的K(i)值。在抑制原发性人类淋巴细胞(IC(50)值约为80 nM)的增殖方面,VX-148比麦考酚酸和VX-497略为有效。外源性鸟苷的存在可以缓解VX-148的抑制活性。VX-148不抑制如成纤维细胞等非淋巴细胞类型的增殖,显示出对IMPDH活性的选择性抑制。VX-148在大鼠和小鼠中具有口服生物利用度;口服VX-148以剂量依赖性抑制小鼠的初级抗体反应,ED(50)值为38 mg kg b.i.d。在小鼠中,VX-148以100 mg kg b.i.d.的剂量显著延长皮肤移植的存活时间。
