branch point of de novo purine nucleotide biosynthesis makes this enzyme an attractive probe for the discovery of antiviral compounds. Introduction of unsaturation at the 2-position of IMP, the natural substrate for IMPDH, produces Michael acceptors at that position, which results in these compounds being inhibitors of IMPDH. Consistent with this mechanism-based molecular design, some of the parent nucleosides
肌苷单磷酸脱氢酶 (IMPDH) 在嘌呤核苷酸从头生物合成的代谢分支点上的作用使该酶成为发现抗病毒化合物的有吸引力的探针。在 IMP(IMPDH 的天然底物)的 2 位引入不饱和度,在该位置产生迈克尔受体,这导致这些化合物成为 IMPDH 的抑制剂。与这种基于机制的分子设计一致,一些母核苷表现出抗病毒活性。
