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.
通式(A)代表的新型菲啶衍生物:
其中 R1 是取代或未取代的低级脂肪族烃基;R 是具有 2 至 6 个碳原子的脂肪族烃链,可任选被选自低级烷基、卤素和羟基的取代基取代;Y 和 Z 各自独立地代表氢、羟基或低级烷氧基;或 Y 和 Z 结合在一起形成亚甲基二氧基或苯基环;
X-是酸残基或氢酸残基,具有抗肿瘤活性,耐化学还原和生物代谢反应,因此有利于用作药物。
