  α-[(Phenoxyethylamino) propyy]-α-phenylacetonitrile derivatives possessing various substituents on the benzene ring (A ring) at the phenylacetonitrile moiety, on the quaternary carbon atom and on the benzene ring (B ring) at the phenoxy moiety, and exhibiting various degrees of ablocking activity, were prepared. The variations in the activity were analyzed qualitatively as well as quantitatively by using physicochemical substituent parameters and a regression technique. The effect of substituents on the A ring was rationalized in terms of a parabolic function of their hydrophobic parameter. As regards substituents on the quaternary carbon atom, alkyl groups were desirable for high activity. The effects of substituents on the B ring were such that an optimum hydrophobic condition exists and that an alkoxy substituent at the o-position as well as smaller substituents at the m-and p-positions are favorable for high activity. The analysis for the combined series of analogs where substituents on the A and B rings are varied showed the existence of an optimum hydrophobicity for the whole molecule for the transport process of the molecule, besides above-mentioned various position-specific structural effects.

  合成了α-[(苯氧乙基氨基)丙基]-α-苯基乙腈衍生物，这些衍生物在苯乙腈部分的苯环（A环）上、在四面体碳原子上，以及在苯氧部分的苯环（B环）上，具有不同的取代基，并表现出各种程度的α-阻断活性。采用物理化学取代基参数及回归技术，对活性的变化进行了定性和定量分析。A环上取代基的影响根据其疏水参数的抛物线函数进行合理化。至于四面体碳原子上的取代基，烷基基团被认为是高活性的理想选择。B环上取代基的影响表明，存在一个最佳的疏水条件，并且在邻位的烷氧取代基以及在间位和对位的较小取代基有利于高活性。针对A环和B环取代基变化的综合系列类似物的分析显示，在分子的运输过程中，整个分子的最佳疏水性存在，此外也考虑了上述不同位置特异的结构效应。

  α-Isopropyl-α-[3-[3-(3-methoxyphenoxy) propylamino] propyl] -α-phenylacetonitrile derivatives containing various substituents on the benzene ring (A ring) at the phenylacetonitrile moiety were prepared, and their Ca2+-antagonistic activity was evaluated. Among these compounds, the N-Me derivatives with m-OMe, p-F, p-Cl, 3, 4-(OMe) 2 and 3, 5-(OMe) 2 substituents on the A ring were found to show higher Ca2+-antagonistic activity than verapamil. The effect of substituents on the A ring was examined quantitatively using physicochemical substituent parameters and regression analysis. The analysis showed that substituents with a π value close to zero are favorable to the activity and that optimum steric conditions exist for m-and p-substituents, corresponding to those of m-OMe and p-F or p-Cl. The analysis for the whole series of analogs where substituents on the A ring, the benzene ring (B ring) at the phenoxy moiety and the quaternary carbon atom are simultaneously varied suggested that there is an optimum molecular hydrophobicity, perhaps participating in the transport process to the site of action, besides position-specific steric and hydrophobic effects.

  制备了α-异丙基-α-[3-[3-(3-甲氧基苯氧基)丙氨基]丙基]-α-苯乙腈衍生物，并评估了它们的 Ca2+ 拮抗活性。在这些化合物中，发现在 A 环上具有 m-OMe、p-F、p-Cl、3，4-(OMe) 2 和 3，5-(OMe) 2 取代基的 N-Me 衍生物比维拉帕米具有更高的 Ca2+ 拮抗活性。利用物理化学取代基参数和回归分析对 A 环上取代基的影响进行了定量研究。分析结果表明，π值接近于零的取代基对活性有利，而 m 和 p 取代基存在最佳立体条件，相当于 m-OMe 和 p-F 或 p-Cl。对同时改变 A 环、苯氧基苯环（B 环）和季碳原子上的取代基的全系列类似物进行的分析表明，除了特定位置的立体效应和疏水效应外，还存在最佳的分子疏水性，这可能参与了向作用部位的迁移过程。

  2-Isopropyl-2-phenyl-5-1N-methyl-2-phenylethylaminol- valeronitrile derivatives of the general formula I wherein R is a methyl, chlorine, bromine, C1 to C4 alkoxyl or methylthio group, preferably administered in the form of soluble acid addition salts, notablythe 2-methylphenyl analog as its hydrochloride, possess significant calcium-antagonistic and cardiac antiarrythmic activity. Preparation is by alkylation of the corresponding butyroni- triie derivative (obtained from the respective substituted benzyicyanide by alkylation with isopropylbromide) by 3,3-diethoxypropylchloride, subsequent acidic hydrolysis of the 5,5-diethoxy-2-isopropyl-2-phenylvaleronitrile derivative obtained to the appropriate aldehyde, and reductive alkylation of this aldehyde with N-methylhomoveratrylamine by catalytic hydrogenation over a platinum or palladium catalyst or chemical reduction using formic acid. The resulting base is optionally neutralized with a pharmaceutically acceptable organic or inorganic acid, e.g. hydrochloric or fumaric acid, into the corresponding acid addition salt.
