PYRIDO(2,3-D)PYRIMIDIN-4(3H)-ONES OF THE GENERAL FORMULA
2-(R-O-)PYRIDO(2,3-D)PYRIMIDIN-4(3H)-ONE
WHEREIN R IS A STRAIGHT OR BRANCHED-CHAIN LOWER ALKYL, WHICH CAN BE SUBSTITUTED BY HYDROXYL GROUPS OR ALKOXY RADICALS, OR AN ALKENYL RADICAL, AND THE SALTS THEREOF WITH PYSIOLOGICALLY COMPATIBLE ACIDS AND BASES. THESE COMPOUNDS EXHIBIT LONG-LASTING DIURECTIC ACTION.
WHEREIN R1 IS ALKYL OF FROM 1 TO 6 CARBON ATOMS; AND R2 IS STRAIGHT-CHAINED OR BRANCHED ALKYL OF FROM 4 TO 10 CARBON ATOMS; CYCLOALKYL OR METHYLCYCLOALKYL WHEREIN THE CYCLOALKYL MOIETY CONTAINS FROM 3 TO 10 CARBON ATOMS, CYCLOALKYL-ALKYL WITH FROM 3 TO 10 CARBON ATOMS IN THE CYCLOALKYL GROUP AND FROM 1 TO 4 CARBON ATOMS IN THE ALKYL SIDE-CHAIN OR BICYCLOALKYL OF FROM 5 TO 7 CARBON ATOMS IN EACH RING; AND THE PHARMACOLOGICALLY COMPATIBLE SALTS THEREOF.
WHEREIN R IS AN UNSUBSTITUTED OR SUBSTITUTED PHENYL OR BENZYL RADICAL, THE SUBSTITUENTS BEING HALOGEN ATOMS OR LOWER ALKYL OR ALKOXY RADICALS, E.G., OF FROM 1 TO 6 CARBON ATOMS, AND N IS 1, 2 OR 3; AND THE PHRMACOLOGICALLY COMPATIBLE SALTS THEREOF. HAVE OUTSTANDING ANTI-EDEMATOUS ACTIVITY AND REDUCE INCREASED CAPILLARY PERMEABILITY.
