Microsomal prostaglandin E2 synthase-1 (mPGES-1) is a potential therapeutic target for the treatment of inflammatory diseases and certain types of cancer. To identify novel scaffolds for mPGES-1 inhibition, we applied a virtual screening (VS) protocol that comprises molecular docking, fingerprints-based clustering with diversity-based selection, protein-ligand interactions fingerprints, and molecular
微粒体前列腺素E2合酶1(mPGES-1)是治疗炎性疾病和某些类型癌症的潜在治疗靶标。为了鉴定抑制mPGES-1的新型支架,我们应用了虚拟筛选(VS)方案,该方案包括分子对接,基于指纹的聚类和基于多样性的选择,蛋白质-配体相互作用指纹以及具有分子力学的分子动力学(MD)模拟Poisson-Boltzmann表面积(MM-PBSA)计算。仔细分析确定的命中,以确保选择新型支架,该支架与mPGES-1结合口袋中的关键残基建立稳定的相互作用,并抑制酶的催化活性。结果,我们发现了两种有前途的化学型,4-(2-氯苯基)-N-[(2-[((丙-2-基)氨磺酰基]甲基}苯基)甲基]哌嗪-1-羧酰胺(6)和N-(4-甲氧基-3- [4-(6-甲基-1,3-苯并噻唑-2-基)苯基]氨磺酰基}苯基)乙酰胺(8),作为非酸性mPGES-1抑制剂,IC50值分别为1.2和1.3μm。最小的8种结构优化产生了
