prepared a new series of 6-arylimidazo[4,5-c]pyridine derivatives. Variation of phenyl groups at the 4-, 6- or 7-position of imidazo[4,5-c]pyridine showed that substitution at the 6-position resulted in receptor-binding activity almost as potent as that of DuP 753. This led to synthesis and evaluation of an extensive series of 6-aryl-imidazo[4,5-c]pyridine derivatives. Some of them were 4-fold more potent
从最近报道的非肽类血管紧张素II(AII)受体拮抗剂开始,我们设计并制备了一系列新的6芳基咪唑并[4,5-c]吡啶衍生物。咪唑并[4,5-c]吡啶的4-,6-或7-位苯基的变化表明,在6-位的取代产生的受体结合活性几乎与DuP 753相同。合成和评估一系列广泛的6-芳基-咪唑并[4,5-c]吡啶衍生物。其中一些在体外的效力比DuP 753强4倍,但当口服给予大鼠时其体内仅显示弱的降压活性。
