Novel α-isopropyl-α-[(phenoxyalkylamino)alkyl]benzeneacetonitrile derivatives, the phenoxyalkylamino moiety of which was introduced in place of the phenethylamino moiety of verapamil (known to be an excellent Ca2+-antagonist), were synthesized and their pharmacological activities were evaluated. These compounds exhibited α-bloking activity along with Ca2+-antagonistic activity, and their activities were influenced by the substituent on the amino nitrogen atom and by the number of carbons between the nitrogen atom and the benzeneacetonitrile moiety (m) as well as that between it and the pheoxy moiety (n). Among these compounds, the N-methyl derivative (2h) where m=n=3, was found to possess a high Ca2+-antagonistic activity and the N-H derivative (2c) in which m=3 and n=2 possessed a high α-blocking activity.
新型α-异丙基-α-[(苯氧烷基氨基)烷基]苯乙腈衍生物的合成,其中苯氧烷基氨基部分取代了维拉帕米(已知为优秀的钙通道拮抗剂)的苯乙基氨基部分,并对其药理活性进行了评估。这些化合物表现出α-受体拮抗活性以及钙通道拮抗活性,其活性受氨基氮原子上的取代基和氮原子与苯乙腈部分之间的碳数(m),以及氮原子与苯氧部分之间的碳数(n)影响。在这些化合物中,N-甲基衍生物(2h),其中m=n=3,表现出较高的钙通道拮抗活性,而N-H衍生物(2c),其中m=3和n=2,则表现出较高的α-拮抗活性。
