The 5HT.sub.2 receptor antagonizing effect of 2'-\x9b2-(1-methyl-2-piperidyl) ethyl! cinnamanilide, a racemic mixture (R S-MPEC) of S-MPEC and R-MPEC isomers is found to be provided practically entirely by the S-MPEC isomer, the R-MPEC being effectively an impurity. Disclosed are pure S-MPEC, mixtures thereof with up to about 10% of R-MPEC, a novel method of resolving the S-MPEC involving a novel intermediate compound, therapeutic compositions containing S-MPEC, and uses thereof for administration to animals, especially humans, in need of 5HT.sub.2 receptor blockage, as for hemorrhoids, varicose veins, venous and coronary insufficiencies, wound healing, and as analgesic or local anesthetic agents.
2'-\x9b2-(1-甲基-2-哌嗪基)乙基!肉桂酰亚胺(S-MPEC和R-MPEC异构体的混合物(R S-MPEC)中,5HT.sub.2受体拮抗作用实际上完全由S-MPEC异构体提供,R-MPEC有效地是杂质。公开的是纯S-MPEC,其中包含多达约10%的R-MPEC混合物,涉及一种新的分离S-MPEC的方法,其中包括一种新的中间化合物,含有S-MPEC的治疗组合物,以及将其用于需要5HT.sub.2受体阻滞的动物,特别是人类,例如用于痔疮,静脉曲张,静脉和冠状动脉不足,伤口愈合以及作为镇痛或局部麻醉剂的用途。
