A series of semi-rigid analogs of phenethylamine was prepared as fixed transoid and cisoid analogs of mebeverine, and tested for spasmolytic activity in vitro. The fixed transoid analogs were more potent than the corresponding cisoid analogs. In this series, tetrahydro-2-napthylamine derivative (2a) which is presumed to take transoid conformation had the most potent activity, and tetrahydroisoquinoline derivatives (2g and 2h) which are presumed to take typical cisoid conformations were less active. These results suggested that the phenethylamine moiety of mebeverine takes the transoid conformation for the manifestation of the spasmolytic activity.
制备了一系列苯乙胺的半刚性类似物作为美贝维林的固定反式和顺式类似物,并测试了体外解痉活性。固定的反式类似物比相应的顺式类似物更有效。在该系列中,被认为具有反式构象的四氢-2-萘胺衍生物(2a)具有最强的活性,而被认为具有典型顺式构象的四氢异喹啉衍生物(2g和2h)活性较低。这些结果表明美贝维林的苯乙胺部分采用反式构象来表现解痉活性。
