Substituted Benzoylguanidines, method for their preparation, their use as antiarrhythmic agents.

摘要

Benzoylguanidines of the formula I where R(1) is hydrogen, Hal, -NO2, -CN, -CF3, R(4)-SOm or R(5)R(6)N-SO2-, where m is zero to 2, R(4) and R(5) are alk(en)yl or -CnH2n-R(7), n is zero to 4, with R(5) also having the meaning of H, and R(6) is H or (C1-C4)-alkyl, with R(5) and R(6) together being able to be 4 or 5 methylene groups, R(2) is -SR(10), -OR(10), -NHR(10), -NR(10)R(11), -CHR(10)R(12), with R(10) and R(11) being identical or different and being -[CHR(16)]s-(CH2)p-(CHOH)q-(CH2)r-(CH2OH)t-R(21) or -(CH2)p-O(CH2-CH2O)q-R(21), R(12) and R(13) being hydrogen or alkyl, or forming a cycloalkyl together with the carbon atom carrying them, R(14) being H, (cyclo)alkyl or -CnH2n-R(15), R(3) is defined as R(1) or is alkyl, hydrogen or -X-R(22), where X is oxygen, S or NR(16), are described, as are the pharmaceutically tolerated salts thereof. The compounds I possess very good anti-arrhythmic properties but do not have any undesirable salidiuretic properties. In addition to this, they are notable for their strong inhibitory effect on the proliferation of cells.
