  discover potent antihypertensive analogues of diltiazem (3a), we prepared 1-benzazepin-2-ones (4). Benzazepinones competitively displace radiolabeled diltiazem, and show the same absolute stereochemical preferences at the calcium channel receptor protein. Derivatives of 4 containing a trifluoromethyl substituent in the fused aromatic ring show potent and long-acting antihypertensive activity. Studies

  作为发现地尔硫卓有效降压类似物的程序的一部分，我们制备了1-benzazepin-2-ones（4）。苯并ze庚因酮竞争性地取代了放射性标记的地尔硫卓，并在钙通道受体蛋白上表现出相同的绝对立体化学偏好。在稠合的芳族环中含有三氟甲基取代基的4的衍生物表现出有效的长效降压活性。对4的代谢的研究导致了代谢稳定的降压钙通道阻滞剂5a和5c。与第二代地尔硫卓类似物TA-3090（3e）相比，苯并ze庚酮5a是更长效且更有效的降压药。

  We have shown that the pyrrolidinylmethyl substituent on the lactam nitrogen (Nl) of benzazepinone and benzothiazepinone calcium channel blocking agents is resistant to metabolic deamination and generally increases the duration and potency of antihypertensive activity in spontaneously hypertensive rats (SHR) relative to (N,N-dimethylamino) ethyl analogs. Additionally, compounds possessing a substituent on the fused aromatic ring are more resistant to metabolic deacylation of the C3 hydroxy function, which may explain why aromatic substituents also frequently increase the potency and/or duration of antihypertensive activity. Our data also indicate the in antihypertensive activity associated with these structural modifications is independent of any effects of potency in vitro. Overall, we interpret these results to indicate that these structural modifications improve antihypertensive activity as a result of increased metabolic stability and, consequently, oral bioavailability.
