A compound represented by formula (I) or a salt thereof;
wherein R1 and R2, which may be the same or different, each represent a hydrogen atom, a halogen atom, a hydroxy group, an alkoxy group, an amino group, an alkylamino group, an aryl group or an alkyl group; R3 and R4, which may be the same, or different, each represent a hydrogen atom, a halogen atom, an alkoxy group, an amino group, an alkylamino group, an aryl group or an alkyl group; R5 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or an arylalkyl group; Q represents an amidino group, a cycloalkyl group, a phenyl group or amonocyclic heterocyclic group except a pyrimidinyl group bonded to the N atom at its 2-position; G represents a nitrogen-containing saturated heterocyclic structure represented by formula:
wherein X1 represents a nitrogen atom or CH,
in which the ring may have a keto group and may have one or more substituents; Z represents a phenyl or heterocyclic group which may have one or more substituents, in which two substituents on the phenyl or heterocyclic group may be connected to each other to form a ring to provide a condensed bicyclic structure as a whole; the substituent on Z and the substituent on G may be connected to each other to form a condensed tricyclic or tetracyclic structure as a whole, and an antitumor agent containing the compound or a salt thereof as an active ingredient.
式 (I) 所代表的化合物或其盐;
其中 R1 和 R2 可以相同或不同,各自代表氢原子、卤素原子、羟基、烷氧基、氨基、烷基氨基、芳基或烷基; R3 和 R4 可以相同或不同,各自代表氢原子、卤素原子、烷氧基、氨基、烷基氨基、芳基或烷基;R5 代表氢原子、烷基、烯基、炔基、芳基或芳烷基; Q 代表脒基、环烷基、苯基或胺环杂环基团,但在 2 位与 N 原子键合的嘧啶基除外; G 代表由式表示的含氮饱和杂环结构:
其中 X1 代表氮原子或 CH、
其中环可具有酮基,并可具有一个或多个取代基; Z代表苯基或杂环基团,可具有一个或多个取代基,其中苯基或杂环基团上的两个取代基可相互连接形成一个环,以提供一个整体的缩合双环结构;Z上的取代基和G上的取代基可以相互连接,形成一个缩合的三环或四环结构整体,以及含有该化合物或其盐作为活性成分的抗肿瘤剂。
