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.
