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.

A condensed pyrimidine derivative of the formula (I):
wherein the ring A stands for an optionally substituted 5-membered ring; B stands for an optionally substituted divalent 5- or 6-membered homo- or hetero-cyclic group; X stands for, among others, amino group; Y stands for, among others, hydrogen atom, halogen atom or amino group; Z stands for a divalent aliphatic group having five or less atoms forming straight chain, optionally having nitrogen, whose chain portion may optionally have a hetero-atom; W stands for, among others, -NH-CO-or -CO-NH-; R¹ stands for an optionally substituted cyclic or chain-like group ; COOR² stands for an optionally esterified carboxyl group; and p denotes an integer of 1 to 4, provided that when -W-R¹ denotes a moiety represented by the formula:
wherein COOR¹⁶ and COOR¹⁷ are, independently, an optionally esterified carboxyl group and n denotes an integer of 1 to 5, p denotes 1, 3 or 4, or a salt thereof, exhibiting highly specific toxicities to various tumor cells and excellent therapeutic effects on methotrexate-resistant tumor cells as well.
