Identification of new microsomal prostaglandin E2 synthase-1 (mPGES-1) inhibitors is currently sought for the treatment of cancer and inflammation. Here we show the results of a Fragment Virtual Screening campaign using the X-ray crystal structure of human mPGES-1 (PDB code: 4AL0). Among the fragments selected and biologically tested, 6 (9H-indeno [1,2-b] [1,2,5]oxadiazolo [3,4-e]pyrazin-9-one) showed
目前正在寻求鉴定新的微粒体前列腺素E 2合酶-1(mPGES-1)抑制剂以治疗癌症和炎症。在这里,我们展示了使用人类mPGES-1(PDB代码:4AL0)的X射线晶体结构进行的碎片虚拟筛选活动的结果。在选择并进行生物学测试的片段中,有6个(9H-茚并[1,2-b] [1,2,5]恶二唑并[3,4-e]吡嗪-9-一)显示出最有希望的mPGES-1抑制活性(在10μM时抑制约30%)。的最小的基于结构的优化6导致化合物15,20和21,具有抑制活性的有希望的增强(IC 50 = 4.6±0.2μM为15; IC 50 = 2.4±1.0μM为20 ; 对于21),IC 50 = 2.4±0.8μM 。前所未有的化学核心和合成新型衍生物的可能性揭示了开发具有潜在抗炎和抗癌特性的mPGES-1抑制剂的新的有吸引力的作用领域。
