摘要

By studying the structural similarity of analgesic imidazolines and 2-phenylnitronyl nitroxides, 20 1-hydroxyl-2-substituted phenyl-4, 4, 5, 5-tetramethylimidazolines (2a–t) were newly synthesized as selective antagonists of prostacyclin receptor (IP receptor). In the in vivo tail-flick assay, 2a–t (dose, 0.13 mmol/kg) receiving mice showed increased pain thresholds ranging from 20.52±7.25% to 90.94±11.97%, which were significantly higher ...
