Abstract
1,237,788. Pyrimido[5,4-d]pyrimidines. DR. KARL THOMAE G.m.b.H. 31 July, 1969 [31 July, 1968; 1 July, 1969 (2)], No. 38447/69. Heading C2C. The invention comprises compounds of formula wherein R 1 is C 1-3 alkyl, allyl or benzyl, R 2 is C 1-3 alkyl or allyl (or NR 1 R 2 is piperidino substituted by 1 or 2 Me or Et groups in the 2,3 and/or 6-positions, or is 1,2,5,6-tetrahydropyridino, hexamethyleneimino, heptamethyleneimino, 3,6 - ethylenehexamethyleneimino, indolino or 1,2,3,4-tetrahydroisoquinolino), and R 3 , R 4 are each C 2-3 -hydroxyalkyl. These compounds are prepared by (1) oxidizing the corresponding 1,2,3,4-tetrahydropyrimido[5,4-d]- pyrimidines (formed by reducing compounds of the above formula having additionally a 4- NR 1 R 2 group), or (2) reacting a compound of the above formula, having a replaceable substituent in place of one or more of the amino groups shown, with HNR 1 R 2 or HNR 3 R 4 . Therapeutic compositions for oral, parenteral or rectal administration comprise compounds of the above formula, which are physiologically active on the heart and circulation, and inhibit thrombocyte aggregation.
