A series of 1-and 3-(1-substituted 4-piperidinyl)-1, 2, 3, 4-tetrahydro-2-oxoquinazolines were synthesized and tested for antihypertensive activity. Among the compounds tested, 1-(2-hydroxy-2-phenethyl)-4-(1, 2, 3, 4-tetrahydro-2-oxo-3-quinazolinyl) piperidine derivatives were generally the most effective in lowering blood pressure in the spontaneous hypertensive rat model. Of these, 1-[2-(4-chlorophenyl)-2-hydroxyethyl]-4-(1, 2, 3, 4-tetrahydro-2-oxo-3-quinazolinyl) piperidine (26) (KF5908) seemed the most promising.
合成了一系列1-和3-(1-取代4-哌啶基)-1, 2, 3, 4-四氢-2-酮喹唑啉,并测试了它们的抗高血压活性。在测试的化合物中,1-(2-羟基-2-苯乙基)-4-(1, 2, 3, 4-四氢-2-酮-3-喹唑啉基)哌啶衍生物通常在自发性高血压大鼠模型中降低血压的效果最佳。其中,1-[2-(4-氯苯基)-2-羟基乙基]-4-(1, 2, 3, 4-四氢-2-酮-3-喹唑啉基)哌啶(26)(KF5908)似乎最具前景。
