Fused ring compounds of formula (I):
(where R1-R4, X1 and X2 represent hydrogen or various substituents, n and m are 1-3 and 2-7 respectively, the dotted lines are double or single bonds and Y is one oxygen or two hydrogens) have magnificent anti-arrhythmic activity, diuretic activity and the ability to improve brain function. For pharmaceutical use they may be formulated with carriers or diluents. They may be prepared by a ring-closing reaction of an indole derivative.
式 (I) 的熔环化合物:
(其中 R1-R4、X1 和 X2 代表氢或各种取代基,n 和 m 分别为 1-3 和 2-7,虚线为双键或单键,Y 为一个氧或两个氢)具有很强的抗心律失常活性、利尿活性和改善大脑功能的能力。用于制药时,它们可与载体或稀释剂一起配制。它们可以通过吲哚衍生物的闭环反应制备。
