  • Patent number: 4399145
    Abstract: The invention relates to new lactam compounds, pharmaceutical compositions containing them (especially those for oral or rectal application) and to processes for the preparation of these compounds and compositions. The new compounds have the general formula ##STR1## wherein X represents a straight or branched alkyl radical with 1 to 4 carbon atoms, preferably a methyl group. The new compounds of formula (I) have sedating-tranquilizing properties. In higher dosages some of them also act as hypno-anesthetics. Moreover the derivative in which X represents the methyl group has anticonvulsant activities. The valuable compounds of formula (I) are prepared in a manner known per se e.g. by reacting an 3-alkyl-3-halogen-2-oxopiperidine (the alkyl having 1-4 carbon atoms) with a metal derivative of 2,3-dihydro-3-oxo-1,2-benzisothiazoldioxid-(1,1) or by reacting an 3-alkyl-3-amino-2-oxopiperidine with o-sulfobenzoic acid dichloride or dibromide or with an o-halomercaptobenzoylhalide, followed by oxydation.

  • Patent number: 4199573
    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.
