glutamate carboxypeptidase II (GCP II, EC 3.4.17.21). The inhibitory potency of these thiol-based compounds against GCP II was found to be dependent on the number of methylene units between the thiol group and pentanedioic acid. A comparison of the SAR of the thiol-based inhibitors to that of the phosphonate-based inhibitors provides insight into the role of each of the two zinc-binding groups in GCP
合成了一系列2-(硫代烷基)戊二酸,并将其评估为谷氨酸羧肽酶II的抑制剂(GCP II,EC 3.4.17.21)。发现这些基于硫醇的化合物对GCP II的抑制能力取决于硫醇基和戊二酸之间的亚甲基单元的数目。将基于硫醇的抑制剂的SAR与基于膦酸酯的抑制剂的SAR进行比较,可以洞悉两个锌结合基团各自在GCP II抑制中的作用。发现最有效的基于硫醇的抑制剂2-(3-巯基丙基)戊二酸(IC(50)= 90 nM)在大鼠中具有口服生物利用度,并且在口服后的神经性疼痛动物模型中表现出功效。
