The present invention addresses the need to identify new antiarrhythmic treatments for both atrial and ventricular arrhythmias. [Solution] Formula (IA): [Wherein R 3 , R 4 and R 5 are independently selected from hydrogen, hydroxy and C 1 -C 6 alkoxy, provided that R 3 , R 4 and R 5 cannot all be hydrogen. Includes their isolated enantiomers, diastereomers and geometric isomers, and mixtures thereof) Or solvates, pharmaceutically acceptable salts, esters, amides, complexes, chelates, stereoisomers, stereoisomer mixtures, geometric isomers, crystalline or amorphous forms, metabolites, metabolism Precursor or prodrug. [Selection figure] None |
