The nitroacridine derivative 9-[3-(N,N-dimethylamino)propylamino]- 1-nitroacridine (nitracrine) is a potent hypoxia-selective cytotoxin for tumor cells in culture. Modifications of the acridine ring result in altered DNA binding properties. This has sugge

The present invention relates to optionally substituted pyrido[2,3-d]pyrimidine-2,4(1H,3H)-diones or optionally substituted pyrido[2,3-d]pyrimidine-2(1H,3H)-ones, i.e., compounds of Formula I: STR1 wherein: Y is --CH2 -- or --C(O)--; R1 is hydrogen or --(CH2)n --R7, wherein: R7 is aryl or heteroaryl, and n is 1 or 2, provided that when Y is --C(O)--, R7 is heteroaryl; and R2, R3, R4, R5 and R6 are hydrogen, or one is selected from lower alkyl, halo, carboxy, methoxycarbonyl, carbamoyl, methylcarbamoyl, di-methylcarbamoyl, methylcarbonyl, methylthio, methylsulfinyl, methylsulfonyl, hydroxymethyl, amino, trifluoromethyl, cyano or nitro; or R2, R3, R4 and R5 are independently selected from hydrogen, lower alkyl, nitro, chloro, fluoro, methoxycarbonyl or methylcarbonyl, provided at least one is hydrogen, and R6 is hydrogen; or a pharmaceutically acceptable ester, ether or salt thereof.
