Novel compounds of the formula:
wherein the ring A is a 5-membered ring, provided that, in the case where the ring A is a pyrrole or pyrroline ring, (i) the N atom in the ring has no active proton or (ii) the ring bonds to Z at the -position of the ring;
B is a divalent cyclic or chain group which may be substituted; one of Q¹ and Q² is N, with the other being N or CH; Y is a hydrogen or halogen atom or a group which bonds to the bonding line with a carbon, nitrogen, oxygen or sulfur atom; X is an amino, hydroxyl or mercapto group;
Z is a straight-chain divalent group having a number of atoms of 2 to 5 composed of carbon atoms which each may be substituted, or of carbon atoms which each may be substituted and one hetero atom which may be substituted;
-COOR¹ and -COOR² each is the same as or different from the other and represents a carboxyl group which may be esterified or its salts are produced by reacting compounds of the formula,
wherein A, B, Q¹, Q², X, Y, and Z are the same as defined above, with compounds of the formula,
wherein -COOR¹ and -COOR² are the same as defined above.The compounds are useful as an antitumor agent.
根据以下公式的新化合物:其中环A是一个5元环,前提是,在环A为吡咯或吡咯烯环的情况下,(i)环中的N原子没有活性质子或(ii)环与Z在环的位置结合;B是可能被取代的二价环或链基团;Q¹和Q²中的一个是N,另一个是N或CH;Y是氢原子或卤素原子,或与碳、氮、氧或硫原子形成键合线的基团;X是氨基、羟基或巯基基团;Z是直链二价基团,由2到5个碳原子组成,每个碳原子可能被取代,或由每个可能被取代的碳原子和一个可能被取代的杂原子组成;-COOR¹和-COOR²分别与另一个相同或不同,并表示可以酯化的羧基或其盐,通过将具有上述定义的A、B、Q¹、Q²、X、Y和Z的化合物与具有上述定义的-COOR¹和-COOR²的化合物反应而产生。这些化合物可用作抗肿瘤剂。
