The compounds of the formula, ##STR1## wherein the ring A is a pyrrole ring which may be hydrogenated; --B-- is a divalent cyclic or chain group which may be substituted; one of Q.sup.1 and Q.sup.2 is N, with the other being N or CH; W is a halogen or hydrogen atom or a group bonded to the bonding line with a carbon, nitrogen, oxygen or sulfur atom, provided that W is not --NH.sub.2 ; X is an amino, hydroxyl or mercapto group; Y is a hydrogen atom or a hydroxyl or amino 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 carbon atoms which each may be substituted and one hetero atom which may be substituted; --COOR.sup.1 and --COOR.sup.2 each is the same as or different from the other and represents a carboxyl group which may be esterified, or salts thereof are provided. The compounds are produced by reacting compounds of the formula, ##STR2## wherein A, --B--, W, W, X, Y, Q.sup.1 and Q.sup.2 are the same as defined above, with compounds of the formula, ##STR3## wherein --COOR.sup.1 and --COOR.sup.2 are the same as defined above, and useful as anti-tumor agents.
化合物的公式为##STR1## 其中环A是吡咯环,可以氢化; --B--是一个二价的环状或链状基团,可以被取代; Q1和Q2中的一个是N,另一个是N或CH; W是卤素或氢原子或与碳、氮、氧或硫原子成键的基团,前提是W不是--NH2; X是氨基、羟基或巯基; Y是氢原子或羟基或氨基; Z是由碳原子组成的直链二价基团,每个碳原子可以被取代,或者是由碳原子和一个可以被取代的杂原子组成的碳链,--COOR1和--COOR2分别与另一个相同或不同,表示可以酯化的羧基,或其盐。该化合物通过将公式##STR2##中的化合物与公式##STR3##中的化合物反应而制得,其中A、-B-、W、W、X、Y、Q1和Q2如上所定义,并可用作抗肿瘤剂。
