Here we describe the SAR of a series of potent and selective mPGES-1 inhibitors based on an oxicam template. Compound 13j demonstrated low nanomolar mPGES-1 inhibition in an enzyme assay. In addition, it displayed PGE(2) inhibition in a cell-based assay (0.42microM) and had over 238-fold selectivity for mPGES-1 over COX-2 and over 200-fold selectivity for mPGES-1 over 6-keto PGF(1alpha).
在这里,我们描述了一系列基于昔布类模板的强效和选择性 mPGES-1 抑制剂的 SAR。化合物 13j 在酶测定中表现出对 mPGES-1 的低纳摩尔抑制作用。此外,它在基于细胞的测定中显示出对 PGE(2)的抑制作用(0.42μM),对 mPGES-1 的选择性超过 COX-2 238 倍以上,对 mPGES-1 的选择性超过 6-酮 PGF(1alpha)200 倍以上。
