A series of (R)-3-amino-4-oxo-2, 3, 4, 5-tetrahydro-1, 5-benzothiazepine-5-acetic acids (4 and 13)and (S)-3-amino-4-oxo-2, 3, 4, 5-tetrahydro-1, 5-benzoxazepine-5-acetic acids (5 and 14) having an(S)-ω-amino-1-carboxyalkylamino group at the 3-position was prepared as part of our search for long-acting angiotensin converting enzyme (ACE) inhibitors. A number of derivatives had potent in vitro and in vivo ACE inhibitory activities. The structure-activity relationship of the series indicated that the duration of in vivo ACE inhibitory activity depends on the length of the carbon chain in the ω-aminoalkylamino substituent at the 3-position. The most prolonged activity was observed with (S)-8-amino-1-carboxyoctylamino derivatives (4d and 5d).
一系列具有(S)-ω-氨基-1-羧基烷胺基的(R)-3-氨基-4-氧代-2,3,4,5-四氢-1,5-苯并噻二嗪-5-乙酸(4和13)以及(S)-3-氨基-4-氧代-2,3,4,5-四氢-1,5-苯并噁二嗪-5-乙酸(5和14)作为我们寻找长效血管紧张素转换酶(ACE)抑制剂的一部分被合成。多个衍生物显示出强大的体外和体内ACE抑制活性。该系列化合物的结构-活性关系表明,体内ACE抑制活性的持续时间取决于3-位上ω-氨基烷胺取代基的碳链长度。具有最长活性的是(S)-8-氨基-1-羧基辛胺基衍生物(4d和5d)。
