title: (R)-3-[(S)-1-carboxy-5-(4-piperidyl)pentyl]amino-4-oxo-2,3,4,5- tetrahydro-1,5-benzothiazepine-5-acetic acid (CV-5975): a new potent and long-lasting inhibitor of angiotensin converting enzyme.
abstract: The synthetic design and the biological activities of structurally new angiotensin converting enzyme (ACE) inhibitors, (R)-3-amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzothiazepine-5-acetic acid derivatives, are described. A number of compounds in this series showed potent ACE inhibitory activity in vitro and in vivo. Structure-activity studies indicated that a piperidyl moiety on the amino group at the 3-position in this series conferred long-lasting ACE inhibitory activity and that the duration of activity depended on the length of the carbon chain in the 1-carboxy-omega-(4-piperidyl)alkyl group. (R)-3-[(S)-1-carboxy-5-(4-piperidyl)-pentyl]amino-4-oxo-2,3,4,5-tetrahydro- 1,5-benzothiazepine-5-acetic acid (CV-5975) was selected as the most promising ACE inhibitor for further studies because of its marked inhibitory activity.
