Novel pyrrolo[2,3-d]pyrimidine antifolates (1a, b and 2a, b) with a nitrogen atom in the bridge chain between the 2,4-diaminopyrrolo[2,3-d]pyrimidine and phenylene rings were designed and efficiently synthesized. These compounds exhibited more potent inhi

A compound of the formula (I) wherein the ring A?may be hydrogenated, X is an amino, hydroxyl or mercapto group, Y is a hydrogen atom or a hydroxyl group, R1, R2, R4 and R5 are each a hydrogen atom, a lower hydrocarbon radical or a chemical bond, Z is -O-, a group of the formula -S(O)n- (n is 0 to 2), or a group of the formula in which R3 is a hydrogen atom, a lower hydrocarbon radical optionally having substituent(s), a group attached through -CO- or -S(O)m (m is 1 or 2) or a chemical bond, -B?- is a divalent cyclic group optionally having substituent(s) or a lower alkylene group optionally having substituent(s), -COOR6 and -COOR7 are each a carboxyl group optionally esterified, and i and j are an integer of 0 to 3 provided that i + j= 1 to 3, or its salt, which is useful as antitumor agent.
