Inosine 5′‐monophosphate dehydrogenase (IMPDH) catalyzes a crucial step in the biosynthesis of guanine nucleotides. Being a validated target for immunosuppressive, antiviral, and anticancer drug development, lately it has been exploited as a promising target for antimicrobial therapy. Extending our previous work on Mycobacterium tuberculosis IMPDH, GuaB2, inhibitor development, we screened a set of
肌苷5'-单磷酸脱氢酶(IMPDH)催化鸟嘌呤核苷酸生物合成中的关键步骤。作为免疫抑制,抗病毒和抗癌药物开发的有效靶标,最近它已被用作抗菌治疗的有希望的靶标。扩展了我们先前关于结核分枝杆菌IMPDH,GuaB2,抑制剂开发的工作,我们筛选了23种新的化学实体(NCE),它们被取代的黄酮(系列1)和1,2,3-三唑(系列2)核心结构所取代。体外幽门螺杆菌IMPDH(Hp IMPDH)和人IMPDH2(h IMPDH2)的抑制活性。所有NCE都具有可接受的分子,物理化学和毒性特性。的范围在10μM浓度下,Hp IMPDH和h IMPDH2的抑制分别为9–99.9%和16–57%。最有效的Hp IMPDH抑制剂25c的IC 50值为1.27μM ,无h IMPDH2抑制活性。中等强度,结构新颖的命中分子25c可作为进一步设计和开发高效Hp IMPDH抑制剂的先导。
