2-Ethynylbenzenealkanamines. A new class of calcium entry blockers
摘要:
A series of 2-(aryl- or alkylethynyl)benzenealkanamines were synthesized. They exhibit antihypertensive activity in spontaneously hypertensive rats and coronary vasodilator activity with minimal negative inotropic activity in the "Langendorff" guinea pig heart in vitro. They have been shown to exert their activity by inhibition of Ca2+ influx across cell membranes. Optimal activity is found among the N-(arylethyl)-5-methoxy-alpha-methyl-2-(phenylethynyl)ben zeneethanamines and -propanamines.

A method for synthesizing a tri-substituted phenyl compound (I) by using a 1,2-addition followed by a 1,4-addition to 1,4-benzoquinone (II):
wherein X is hydroxy, alkoxy or alkanoyloxy, Ar¹ is an organic group and R is an unsubstituted or substituted alkyl group.
一种通过对 1,4-苯醌(II)进行 1,2-加成后再进行 1,4-加成来合成三取代苯基化合物(I)的方法:
其中 X 是羟基、烷氧基或烷酰氧基,Ar¹ 是有机基团,R 是未取代或取代的烷基。
