α-Alkyl-α-[(phenoxypropylamino)propyl]benzeneacetonitrile derivatives containing various substituents on the ring of the benzeneacetonitrile moiety (A), the quaternary carbon atom and the ring of the phenoxy moiety (B) were prepared, and their Ca2+-antagonistic activities were evaluated. Among these compounds, the N-Me derivatives with a 3, 4, 5-(OMe)3 group on the A ring, an iso-Pr group on the quaternary carbon atom, and a m-OMe, 3, 5-(OMe)2, 3, 5-Me2 or 3, 4, 5-(OMe)3 group on the B ring were found to possess Ca2+-antagonistic activity higher than pA2=9. The effects of substitutions at the A ring, the quaternary carbon atom and the B ring are discussed.
含有不同取代基的α-烷基-α-[(苯氧丙胺)丙基]苯乙腈衍生物被合成,并评估了它们的Ca2+拮抗活性。在这些化合物中,具有在A环上带有3, 4, 5-(OMe)3基团、在四级碳原子上带有iso-Pr基团,以及在B环上带有m-OMe、3, 5-(OMe)2、3, 5-Me2或3, 4, 5-(OMe)3基团的N-Me衍生物被发现具有高于pA2=9的Ca2+拮抗活性。讨论了在A环、四级碳原子和B环上的取代效应。
