摘要:
1,7-Dialkyl-1,2-dihydro-4-hydroxy-1,8-naphthyridine-3-carboxylic acid alkyl esters are prepared by cyclization of 2-((2alkoxycarbonylethyl)alkylamino)-6-alkylnicotinic acid alkyl esters. The compounds so produced exhibit in vivo antibacterial activity.
IN WHICH R, R1 AND R2 ARE INDEPENDENTLY SELECTED FROM THE GROUP, CONSISTING OF -H AND LOWER ALKYL RADICALS, R3 AND R4 ARE INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF -H, LOWER ALKYL AND LOWER PERFLUOROALKYL RADICALS, X IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF -CN AND
1H-TETRAZOL-5-YL
RADICALS, AND PHARMACEUTICALLY ACCEPTABLE ACID ADDITION SALTS THEREOF, POSSESS CENTRAL NERVOUS SYSTEM DEPRESSANT AND ANTI-INFLAMMATORY PROPERTIES WHEN ADMINISTERED TO WARM BLOODED ANIMALS.
摘要:
THE DISCLOSURE IS DIRECTED TO SUBSTITUTED 2-PHENYL-5HPYRROLO(2,3-D)PYRIMIDINE-5,6-(7H)DIONES, AND A PROCESS FOR THEIR PREPARATION, HAVING THE STRUCTURAL FORMULA:
R1 IS HYDROGEN OR LOWER ALKYL, R5 IS PHENYL, HALOPHENYL, LOWER ALKYLPHENYL OR LOWER ALKOXYPHENYL; AND R6 IS METHYL OR ETHYL.
THE COMPOUNDS HAVE PHARMACOLOGICAL ACTIVITY AS CENTRAL NERVOUS SYSTEM DEPRESSANTS IN THAT THEY DECREASE MOTOR ACTIVITY AND DECREASE RESPIRATION IN A HOST.
