  Synthesis and selective cyclooxygenase-2 (COX-2) inhibitory activity of a series of novel bicyclic pyrazoles

  摘要：

  Novel series of pyrazolo[5, 1-b] 1,3-oxazolidines, pyrazolo[5, 1-b] 1,3-oxazines and imidazolidino[1,2-d]pyrazoles were synthesized. These compounds were evaluated in vitro for their ability to inhibit cyclo oxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) in human whole blood (HWB). Several of the compounds were found to be novel and selective COX-2 inhibitors, the most potent and selective being 1-(5-cyclohexyl (2H, 3 H -pyrazolo [5, 1-b]-1, 3-oxazolidin-6-yl)-4-(methylsulfonyl)benzene, 7a (IC50 for COX-1 > 100 muM; for COX-2 = 1.3 M).
