Quinazoline derivatives of formula:
wherein r represents: 1) a straight or branched chain unsaturated hydrocarbon group, or 2) a straight or branched chain saturated or unsaturated hydrocarbon group which is substituted by at least one: heteroatom, the or each heteroatom being halogeno when R is a C1 hydrocarbon group; or saturated carbocyclic group; or group containing at least one heteroatom, the or each heteroatom being 0, N or S when R contains a cyclic group; and n is 0 or an integer of 1-4; X or, when n is an integer of at least 2, each X independently, represents a halogeno, C1-C4 alkyl, aryl or aralkyl group or a group including at least one heteroatom; and Y represents a group of formula:-
wherein m . 1 (poly-L-glutamates); and the pharmaceutically acceptable salts and esters thereof, which are suitable as anti-cancer agents.
式中的喹唑啉衍生物:
其中 r 代表1) 直链或支链不饱和烃基,或 2) 被至少一个杂原子取代的直链或支链饱和或不饱和烃基:杂原子,当 R 为 C1 烃基时,或每个杂原子为卤素;或饱和碳环基团;或含有至少一个杂原子的基团,当 R 含有环状基团时,或每个杂原子为 0、N 或 S;且 n 为 0 或 1-4 的整数;X 或当 n 为至少 2 的整数时,每个 X 独立地代表卤素、C1-C4 烷基、芳基或芳烷基或包含至少一个杂原子的基团;且 Y 代表式中的一个基团:- 1.
其中 m .1(聚-L-谷氨酸盐);及其药学上可接受的盐和酯,可用作抗癌剂。
