boxyli c acid derivatives was prepared as angiotensin II (AII) receptor antagonists. When evaluated in an in vitro binding assay using COS cells transfected with a cDNA encoding a human AT1 angiotensin II receptor, the compounds in this series showed Ki values in the range of 0.4-4.0 nM. In anesthetized spontaneously hypertensive rats (SHRs), administration of the 6-propyl derivative 4d (1 mg/kg, i
制备了一系列新的6-烷基-7-氧代-4,7-二氢吡唑并[1,5-α-嘧啶-3-羧基]酸衍生物作为血管紧张素II(AII)受体拮抗剂。当在体外结合测定中使用转染了编码人AT1血管紧张素II受体的cDNA的COS细胞进行评估时,该系列化合物的Ki值在0.4-4.0 nM范围内。在麻醉的自发性高血压大鼠(SHRs)中,使用6-丙基衍生物4d(1 mg / kg,iv)可使平均血压(MBP)与正常值相比最多降低了30 mmHg以上。
