  • Patent number: 5989882
    Abstract: The invention relates to acarviosyl transferase from actinomycetes, mainly from Actinoplanes sp. SE 50/110 and its mutants, to a process for isolating, purifying and characterizing the enzyme, to the isolation and characterization of the acbD gene encoding the acarviosyl transferase, to the expression of the acarviosyl transferase in a heterologous host organism, to the use of the acarviosyl transferase for converting acarbose minor constituents into acarbose or for preparing acarbose homologues, to the use of the acarviosyl transferase in acarbose purification, and also to the preparation of production mutants in which formation of minor constituents is reduced by means of inactivation of the acarviosyl transferase gene.

  • Patent number: 5328931
    Abstract: N-alkylated 1,4-dihydropyridinedicarboxylic acid esters can be prepared either by reaction of aldehydes with acetoacetic esters and amines, optionally with isolation of the corresponding ylidene compounds, or by reaction of aminocrotonic acid esters with ylidene compounds and subsequent alkylation of the NH function. The N-alkylated 1,4-dihydropyridinedicarboxylic acid esters can be employed as active compounds in medicaments, in particular as cerebral therapeutics.

  • Patent number: 5223517
    Abstract: Heterocyclically substituted cycloalkano[b]-indolesulphonamides can be prepared by reaction of appropriate N-unsubstituted indoles with acrylonitrile, followed by hydrolysis, esterification or amidation, or by reaction of heterocyclically substituted hydrazines with cycloalkanones or by subsequent introduction of the heterocyclic group into appropriate indole derivatives. The heterocyclically substituted cycloalkano[b]-indolesulphonamides can be employed for the treatment of thromboembolic disorders, ischaemias, arteriosclerosis, asthma, allergies and for the prophylaxis of myocardial infarcts.
