Abstract: Derivative of 1-hydroxy-benzo-2,3,1-diazaborines which are substituted in the 2-position by a sulfo group linked to a defined aliphatic radical like alkyl or alkenyl and which may be substituted on the benzene ring by one or more lower alkyl radicals and/or halogen atoms and salts of such compounds. The pharmaceutical compositions containing these diazaborines are highly effective against gram-negative bacteria. The new compounds are prepared by reacting o-formyl phenyl boric acid, which may be substituted, with the respective aliphatic sulfonic acid hydrazide or by reacting the respective (substituted) benzaldehyde sulfonylhydrazone with a boron trihalogenide.

Abstract: The invention relates to new cephalosporin derivatives, which are effective as antibacterial agents, methods for their production, and medicines containing these products. These compounds have high effectiveness against numerous pathogenic microorganisms, and particularly against gram negative bacilli. Beyond that, the compounds according to the invention are also suitable as intermediate products for the production of further .beta.-lactam antibiotics.

Abstract: Drug compositions including a lactam of the substituted ortho-sulfobenzoic acid imido pyrrolidone-2, piperidone-2, or caprolactam type.The drug compositions have valuable therapeutic properties: they are immunouppressive, sedative and have antitumor activity. The method of inducing sedation in warmblooded animals.

Abstract: Lactams of the substituted ortho-sulfobenzoic acid imido pyrrolidone-2, piperidone-2, or caprolactam type. The compounds are useful drugs having therapeutical properties. They are immunosuppressive, sedative, and have antitumor activity. They are produced, for instance, by reacting bromo-lactams with a metal salt of o-sulfobenzoic acid imide.
