  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.

  As part of a program aimed at identifying novel analogues of diltiazem, we developed several synthetic routes for 3-alkylbenzazepinones, both in racemic and nonracemic form. Structure-activity relationship studies in this series have led to identification of several analogues as potent calcium channel blocking agents, both in vitro and in vivo. Analogues containing a 6-trifluoromethyl substituent (17a and 17b) are the most potent vasorelaxants in vitro. The oral antihypertensive activity of these compounds is comparable to its 3-acetoxy derivative 1 (X = 6-CF3) and 8-chlorodiltiazem (2b). The 3-allyl analogue 17c is a more potent antihypertensive agent than 17a, 17b, or 8-chlorodiltiazem (2b), and has a longer duration of action in vivo.
