potent, highly selective, non-toxic, and irreversible inhibitor of γ-glutamyl transpeptidase (GGT) was substantially improved. This route furnishes GGsTop in four steps with an overall yield of 32% from inexpensive starting materials, i.e., the yield is increased approximately sixfold relative to the previous protocol. The synthesis and inhibitory activity evaluation of potential hydrolysis products of
先前报道的合成方法可合成2-氨基-4-[3-(羧甲基)苯氧基](甲氧基)磷酸基}丁酸(GGsTop),这是一种有效,选择性高,无毒且不可逆的γ-谷氨酰转肽酶抑制剂(GGT)得到了显着改善。该路线分四个步骤提供了GGsTop,其价格便宜,起始原料的总产率为32%,即,相对于先前的方案,产率提高了大约六倍。GGsTop潜在水解产物的合成和抑制活性评估清楚地表明GGsTop是活性抑制剂,可以想到的水解产物几乎不影响人类GGT的活性。
