Abstract

Various 5-aminobenzofuran derivatives were prepared from khellin and screened intravenously in the dog for their potential antiarrhythmic activity against ouabain-induced ventricular arrhythmia and in the Harris test. From systematic structural variations it was found that two methoxy groups in positions 4 and 7 on the benzofuran ring, a tertiary aminoethoxy side chain in position 6, and a N-methylurea group in position 5 led to the ...
