Here we report on novel, potent 3,3-dimethyl substituted N-aryl piperidine inhibitors of microsomal prostaglandin E synthases-1(mPGES-1). Example 14 potently inhibited PGE2 synthesis in an ex vivo human whole blood (HWB) assay with an IC50 of 7nM. In addition, 14 had no activity in human COX-1 or COX-2 assays at 30μM, and failed to inhibit human mPGES-2 at 62.5μM in a microsomal prep assay. These data
在这里我们报告新型,有效的微粒体前列腺素E合酶-1(mPGES-1)的3,3-二甲基取代的N-芳基哌啶抑制剂。实施例14在离体人全血(HWB)测定中有效抑制PGE 2合成,IC 50为7nM。此外,有14种在30μM的人COX-1或COX-2分析中没有活性,并且在微粒体制备分析中未能抑制62.5μM的人mPGES-2。这些数据与选择性mPGES-1介导的PGE2减少相一致。在狗中,有14剂的口服生物利用度(74%),清除率(3.62mL /(min * kg))和分布体积(Vd,ss = 1.6L / kg)值在我们的目标范围内。由于这些原因,选择了14个进行进一步研究。
