It has been found that the novel compounds of the formula
wherein R, is phenyl substituted with 1 to 3 lower alkoxy groups or 1 to 3 halogens, R2 is hydroxy, lower alkoxv. lower alkanovloxv. lower cvcloalkvlcarbonvloxv.
R3 and R, are, independently, lower alkyl, phenyl lower alkyl or, taken together, form a piperidine or pyrrolidine ring, n is 2 to 4 and m is 1 to 2,
and pharmaceutically acceptable acid addition salts thereof have activity as calcium channel blockers and, accordingly, are useful as agents for treating ischemia and as agents for lowering blood pressure. They can be prepared by reacting a compound of the formula
with a compound of the formula
and optionally converting the compound thus obtained to a compound wherein R2 is other than hydroxy.
发现式中的新型化合物
其中 R 是被 1 至 3 个低级烷氧基或 1 至 3 个卤素取代的苯基,R2 是羟基、低级烷氧基、低级烷烃氧基、低级环烷烃氧基、低级环羰基氧基。
R3和R, 独立地是低级烷基、苯基低级烷基,或共同形成哌啶或吡咯烷环,n为2至4,m为1至2、
及其药学上可接受的酸加成盐具有钙通道阻滞剂的活性,因此可用作治疗缺血和降低血压的药物。它们可以通过将式
与式
并选择性地将由此得到的化合物转化为 R2 为羟基以外的化合物。
