Restriction is good for inhibition! Tetrahydrobenzothiophene‐derived rigid mimics of the type II dehydroquinase (DHQ2)‐catalyzed reaction intermediate are reported. These derivatives fix the interaction with the tyrosine, the base that initiates the enzymatic reaction, in an inappropriate orientation for catalysis. Two competitive inhibitors in the series, 2‐propenyl derivative 5 e and 2‐cyclopropylethyl compound
限制对抑制有好处!据报道,由四氢苯并噻吩衍生的II型脱氢喹啉酶(DHQ2)催化反应中间体的刚性模拟物。这些衍生物在不适当的催化方向上固定了与酪氨酸的相互作用,酪氨酸是引发酶促反应的基础。该系列中的两种竞争性抑制剂2-丙烯基衍生物5 e和2-环丙基乙基化合物5 i(如图所示)与幽门螺杆菌的DHQ2形成了结晶,其X射线结构分别为1.95Å和1.85Å。。
