  Benzazepinone calcium channel blockers. 4. Structure-activity overview and intracellular binding site

  摘要：

  We have synthesized a series of benzazepinones (2) in order to determine the structure-activity relationships (SAR) for calcium channel blockers related to diltiazem. A prerequisite for calcium channel blocking activity in vitro and in vivo is the presence of two pharmacophores: a 4'-aryl methyl ether and a basic substituent appended to N1 with a pK(a) in the physiological range. When these constraints are satisfied, a wide variety of substitution is tolerated at C6, C7, and C3. The presence of an electron-withdrawing group at C6 appears to enhance potency in vitro and in vivo. For such benzazepinones, activity is primarily dependent upon lipophilicity, as measured by log P. We believe these compounds must partition into the cell membrane in order to access their receptor. The quaternary methiodide 15k was used to demonstrate that the binding site for benzazepinones is on the intracellular face of the membrane. This work represents the first comprehensive SAR of diltiazem-like calcium channel blockers.

  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。
