Disclosed are novel 1,2,4-triazin-5-one biphenyl derivatives having structural formula (I) useful as non-peptide antagonists of angiotensin II receptor: ##STR1## where R.sub.1 represents alkyl, cycloalkyl, or substituted or unsubstituted aryl; R.sub.2 represents alkyl, substituted or unsubstituted aryl, or arylalkyl; A and D independently represent C--R.sub.3, N, NH or C.dbd.O, wherein when A and D independently denote C--R.sub.3 or N, b and c are independently a double bond, and when A and D independently denote NH or C.dbd.O, b and c are independently a single bond; provided that b and c are not both double bonds; and R.sub.3 is hydrogen, dialkylphosphonate or halogen; and pharmaceutically acceptable salts thereof. Also disclosed is the use of the compounds of formula (I) as non-peptide antagonists of angiotensin II receptor, in the treatment of cardiovascular diseases, in particular hypertension and congestive heart failure.
本文披露了具有结构式(I)的新型1,2,4-三嗪-5-酮联苯衍生物,其可用作血管紧张素II受体的非肽拮抗剂:其中R.sub.1代表烷基、环烷基或取代或未取代芳基;R.sub.2代表烷基、取代或未取代芳基或芳基烷基;A和D独立地表示C--R.sub.3、N、NH或C.dbd.O,其中当A和D独立地表示C--R.sub.3或N时,b和c独立地表示双键,当A和D独立地表示NH或C.dbd.O时,b和c独立地表示单键;但要求b和c不同时为双键;R.sub.3为氢、二烷基磷酸酯或卤代素;及其药学上可接受的盐。还披露了将式(I)化合物用作血管紧张素II受体的非肽拮抗剂,用于治疗心血管疾病,特别是高血压和充血性心力衰竭。
