摘要:
COMPOUNDS ARE OF THE CLASS OF ARYL-SUBSTITUTED-1-SUBSTITUTED-4-ARYL-PYRIDO(2,3,-D)PYRIMIDIN-2-ONES, WHICH ARE USEFUL AS ANTI-INFLAMMATORY AGENTS. INTERMEDIATES FOR PREPARATION INCLUDE THE CORRESPONDING 1-UNSUBSTITUTED-4-ARYLPYRIDO(2,3-D)PYRIMIDIN-2-ONES, COMPOUNDS WHICH ARE PYRIDYL-PHENYL KETONE IMINES AND COMPOUNDS WHICH ARE ARYL-SUBSTITUTED-2-AMINO-NICOTINONITRILES OF WHICH THE LATTER ARE ALSO USEFUL AS ANTI-INFLAMMATORY AGENTS.

7-HYDROXYLAMINO-1,3,5-TRIAZAADAMANTANE AND PROCESS FOR PRODUCTION THEREOF BY REACTING TRIS(HYDROXYMETHYL) NITROMETHANE WITH AMMONIA TO PRODUCE THE NITRO-ADAMANTANE DERIVATIVE, AND REDUCING SAME IN THE PRESENCE OF A PALLADIUM CATALYST TO PRODUCE THE HYDROXYLAMINO DERIVATIVE. THE COMPOUNDS HAVE UTILITY AS BACTERIOSTATS AND FUNGISTATS.
WHEREIN R1 and R2, which may be identical to or different from each other, are each morpholino, thiomorpholino, 1-oxidothiomorpholino, 1,1-dioxido-thiomorpholino or piperidino, where each of these may optionally have a lower alkyl substituent attached thereto; piperazino; N''-acyl-piperazino; N''-carbamoylpiperazino; N''-lower alkyl-piperazino; dialkanol-amino; or alkylenediamino; and R3 is hydrogen or methyl; AND THEIR NON-TOXIC, PHARMACOLOGICALLY ACCEPTABLE ACID ADDITION SALTS; THE COMPOUNDS AS WELL AS THEIR SALTS ARE USEFUL AS INHIBITORS OF THROMBOCYTE AGGREGATION AND ADHESIVENESS.

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.

Novel 2,4,7-trisubstituted-pyrido(2,3-d)pyrimidine-6carboxamides have been produced which have central nervous system depressant activity and are useful pharmacological agents in the calming of animals.
摘要:
WHEREIN R1 stands for hydrogen or a lower alkyl radical; R2 stands for hydrogen, a lower alkyl radical, hydroxyl group, a halogen atom, a lower alkoxy radical, an amino radical or a lower alkylthio radical; R3 stands for hydrogen, a lower alkyl radical, hydroxyl group, a lower alkoxy radical, a lower alkylthio radical or a radical represented by the formula (WHEREIN R'' stands for hydrogen, an alkyl radical, a cycloalkyl radical, an amino radical, a hydroxyalkyl group or an alkyl substituted amino alkyl radical, and R'''' stands for hydrogen or an alkyl radical, R'' and R'''' may be the same or a different radical and R'' and R'''' may bond together to form a 5- or 6membered heterocyclic ring containing a nitrogen hetero atom); and R4 stands for hydrogen or an alkyl group. Such derivatives are useful as antibacterial agents. A 5,8-dihydro-5-oxopyrido (2,3-d) pyrimidine derivative represented by the following formula
摘要:
THE DISCLOSURE IS DIRECTED TO 5,6,7,-TETAHYDRO-5-OXOPYRIDO(2,3-D)PYRIMIDINE-6-CARBONITRILES AND TO 4-((2CYANOETHYL)ALKYLAMINO)-5-PRIMIDINE CARBOXYLIC ACID ESTERS WHICH ARE INTERMEDIATES IN THEIR PREPARATION. BOTH THE FINAL PRODUCTS AND THE INTERMEDIATES HAVE CENTRAL NERVOUS SYSTEM ACTIVITY AS DEPRESSANTS.
