Abstract:
This invention concerns 5-arylbenzo(b) (1,7)naphthyridine derivatives which have pharmacological activity as antitubercular agents. Certain compounds also possess amebacidal or central nervous system depressant activity.
Abstract:
THE DISCLOSURE IS DIRECTED TO NOVEL 3,4-DIHYDROACRIDIN2(1H)-ONE DERIVATIVES OBTAINED BY THE REACTION OF OAMINOCARBONYL DERIVATIVES WITH CYCLOHEXANE-1,4-DIONE IN THE PRESENCE OF A STRONG ACID. THE COMPOUNDS ARE USEFUL AS CENTRAL NERVOUS SYSTEM DEPRESSANTS IN THAT THEY PRODUCE A CALMING EFFECT IN THE HOST.
Abstract:
THIS INVENTION CONCERNS 2-HALO-3-SUBSTITUTED INDOLES WHICH ARE USEFUL AS BRONCHODILATORS. FURTHER, IT RELATES TO THE PROCESS OF PREPARING SOME OF THESE COMPOUNDS BY THE HALOGENATION OF APPROPRATE 3-SBUSTITUTED INDOLES.
Abstract:
Ortho-mercaptoaroylamides and pharmaceutically acceptable salts thereof exhibit hypoglycemic activity in warm-blooded animals. The compounds may be prepared directly by the reaction of a secondary amine with a 2-imino-1,3-benzothiazin-4-one or indirectly by the reaction of the desired amine with (ochlorocarbonylphenyl) dithioether followed by reduction of the disulfide linkage.
Abstract:
This invention concerns 2-amido-6-aminopenicillanic acids, 2amido-6-haloimidopenicillins, 2-amido-6-alkoxyimidopenicillins, 2-amido-7-amino-cephalosporanic acids, 2-amido-7-haloimidocephalosporins and 2-amido-7-alkoxyimido-cephalosporins which are useful as intermediates in the preparation of synthetic penicillins and cephalosporins having potent antibiotic activity. Further, it relates to a process for the preparation of these intermediates from penicillins and cephalosporins. Still further, it concerns the preparation of 6-aminopenicillanic acid and 7aminocephalosporanic acid by the respective hydrolysis of 2amido-6-aminopenicillanic acids and 2-amido-7aminocephalosporanic acids.
Abstract:
This invention concerns pyrrolo (1,2,3-de)quinoxalin-2(3H)-ones and related compounds which are pharmacologically active as central nervous system depressants.
Abstract:
This invention concerns 2-amido-6-aminopenicillanic acids, 2amido-6-haloimidopenicillins, 2-amido-6-alkoxyimidopenicillins, 2-amido-7-aminocephalosporanic acids, 2-amido-7haloimidocephalosporins and 2-amido-7-alkoxyimidocephalosporins which are useful as intermediates in the preparation of synthetic penicillins and cephalosporins having potent antibiotic activity. Further, it relates to a process for the preparation of these intermediates from penicillins and cephalosporins. Still further, it concerns the preparation of 6-aminopenicillanic acid and 7aminocephalosporanic acid by the respective hydrolysis of 2amido-6-aminopenicillanic acids and 2-amido-7aminocephalosporanic acids.
Abstract:
NOVEL PENICILLANIC ACID DERIVATIVE POSSESSING ANTIBACTERIAL ACTIVITY HAVE BEEN PREPARED BY THE REACTION OF AN ENAMINE WITH 6-ISOCYANATOPENICILLANIC ACID TRIMETHYLSILYL ESTER.
