, (2008/06/13)
A novel pyrimidine derivative having an excellent antitumor activity, which is represented by the following general formula (I) or a pharmacologically acceptable salt thereof: STR1 wherein R1 represents a hydroxyl or amino group; R2 represents a phenylene, pyridinediyl, thiendiyl, furandiyl or thiazoldiyl group, --CO2 R5 and --CO2 R6 may be the same or different from each other and each represents a carboxyl group or a carboxylic acid ester, the part STR2 A represents an oxygen atom, a group represented by the formula: STR3 (wherein R3 and R4 may be the same or different from each other and each represents a hydrogen or halogen atom or a hydrocarbon group which may be substituted, or alternatively R3 and R4 may be united to form an alkylidene group which may be substituted) or a group represented by the formula: STR4 (wherein R70 represents a hydrogen atom or a hydrocarbon group), and n is an integer of 1 to 3, provided that the compound in which R1 represents oxygen, and hydrogen is attached to nitrogen at 3-position is included in the above shown definition, a process for preparation the same, and an antitumor drug containing the same.
Synthesis and antitumor activities of novel 6-5 fused ring heterocycle antifolates: N-[4-[ω-(2-amino-4-substituted-6,7- dihydrocyclopenta[d]pyrimidin-5-yl)alkyl]benzoyl]-L-glutamic acids
