competitive binding assay and three had beta 1-receptor selectivity. Compared to sotalol, a reference class II/IIIagent, arylpiperazine 7a (4-[(methylsulfonyl)amino]-N-[(4- phenylpiperazin-2-yl)methyl]benzamide) demonstrated beta 1-selectivity and was 1 order of magnitude more potent in the in vitro classIII and the beta 1-receptor screens. Compound 7a was evaluated further and found to be effective in
