The present invention relates to benzo\x9bc!phenanthridinium derivative of the general formula A: ##STR1## wherein M and N individually represent a hydroxyl or lower alkoxy group, or M and N simultaneously represent a hydrogen atom or together form a methylenedioxy group, X.sup.- represents an acid residue or a hydrogen acid residue, and R represents a lower alkyl group, and a process for preparing such derivatives. The compounds exhibit both potent antitumor activity and platelet aggregation inhibition activity, and are expected to be useful for the treatment of tumors. The process has good reproducibility and may be effected under moderate conditions, and therefore the process is practically useful. In addition, hydrogen salts of the present compounds have an enhanced stability, which is an advantage in formulating the same into pharmaceutical preparations.
本发明涉及一般式A的苯并[中文字符]菲啉衍生物:其中M和N分别代表一个羟基或较低的烷氧基团,或者M和N同时代表一个氢原子或一起形成一个亚甲二氧基基团,X.sup.-代表一个酸残基或一个氢酸残基,R代表一个较低的烷基团,以及制备这种衍生物的方法。这些化合物表现出强大的抗肿瘤活性和抑制血小板聚集活性,预计对肿瘤治疗有用。该方法具有良好的可重复性,可以在适中条件下实施,因此该方法在实际中是有用的。此外,本化合物的氢盐具有增强的稳定性,这是将其配制成药物制剂的优势。
