(Z)-5-benzylidene-2-iminothiazolidin-4-one scaffold was used as lead in rational design of novel inhibitors. Besides, we further designed, synthesized, and evaluated 5-((1,3-diphenyl-1H-pyrazol-4-yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-triones and structurally related derivatives for their in vitro inhibitory activities. According to in vitro activity assays, a number of these compounds were capable of
人类mPGES-1已成为探索下一代抗炎药的有希望的靶标,因为预期选择性mPGES-1抑制剂可以区别性地抑制诱导的PGE 2的产生,而不会阻止其他前列腺素的正常生物合成,包括稳态PGE 2。因此,据信这种治疗方法可减少与传统非甾体抗炎药(tNSAIDs)和选择性COX-2抑制剂(coxibs)的应用相关的不良反应。从基于结构的美德筛选中鉴定出,具有(Z)-5-亚苄基-2-亚氨基噻唑烷-4-酮骨架的化合物被用作新型抑制剂合理设计的先导。此外,我们进一步设计,合成和评估了5-((1,3-diphenyl-1H-吡唑-4-基)亚甲基)嘧啶-2,4,6(1 H,3 H,5 H)-三酮及其结构相关的衍生物具有体外抑制活性。根据体外活性测定,许多这些化合物能够抑制人mPGES-1,对mPGES-1的选择性比COX同工酶高。
