  • Patent number: 6506937
    Abstract: Benzenesulfonylureas and -thioureas of the formula I where R(1) is H or (fluoro)methyl, R(2) is H, Hal or (fluoro) (mercapto)alk(oxy)yl, E is O or S; Y is —[CR(3)2]n—, where R(3)=H or alkyl and n=1-4, X is H, Hal or alkyl and Z is Hal, NO3 or alk(yl)oxy, are described. The compounds I are used for treatment of disturbances in cardiac rhythm and prevention of sudden cardiac death caused by arrhythmia, and can therefore be used an antiarrhythmics. They are particularly suitable for those cases where arrhythmias are a consequence of a narrowing of a coronary vessel, such as angina pectoris or acute cardiac infarction.

  • Patent number: 5360808
    Abstract: Arylcarbonylaminoalkyl-dihydro-oxo-pyridines of Formula I ##STR1## are disclosed wherein aryl is an aromatic or heteroaromatic system, n is zero through 5; R and R(1), are hydrogen, or loweralkyl; W is hydrogen, (hetero)-(aryl)-loweralkyl; Z is hydrogen, CH.sub.2 OR(2.sub.), CHO, (CO)OR(2), (CO)NR(2).sub.2.Processes for the preparation of compound I are also disclosed.Compounds I are suitable for the treatment of disorders of the cardiovascular system, for example of hypertension, of cardiac insufficiency or of disturbances of blood flow in the coronary systems such as, for example, angina. Disturbances of cerebral and peripheral blood flow are likewise influenced beneficially. Furthermore, compounds I are able to influence smooth-muscle organs such as uterus, bronchi, intestines and biliary system, the urinary tract (ureter, bladder and urethra) in the sense of spasmolysis.
