A novel phenanthridinium derivative represented by general formula (A):
wherein R1 is a substituted or unsubstituted lower aliphatic hydrocarbon group; R is an aliphatic hydrocarbon chain having 2 to 6 carbon atoms which may optionally be substituted with a substituent selected from the group consisting of a lower alkyl group, a halogen and a hydroxy group; each of Y and Z independently represents a hydrogen, a hydroxy or a lower alkoxy group; or Y and Z are combined together to form methylenedioxy or a phenyl ring;
and, X− is an acid residue or a hydrogen acid residue, exhibits an antitumor activity and has resistance to chemical reduction as well as biological metabolic reactions and is thus advantageous for use as a medicine.
一种新的苯并三氮杂环衍生物,其通式表示为(A):其中R1是取代或未取代的低级脂肪烃基;R是具有2至6个碳原子的脂肪烃链,可以选择性地被取代为来自以下组的取代基:低级烷基,卤素和羟基;每个Y和Z独立地表示氢,羟基或低级烷氧基;或Y和Z组合成亚甲二氧基或苯环;而X-是酸残基或氢酸残基。该化合物具有抗肿瘤活性,具有抗化学还原和生物代谢反应的抵抗力,因此适用于作为药物。
