We have discovered a novel series of N-[2-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-naphthalen-1-yl] amides that are potent openers of K-ATP channels and investigated structure-activity relationships (SAR) around the 1,2-disubstituted naphthyl core. A-151892, a prototype compound of this series, was found to be a potent and efficacious potassium channel opener in vitro in transfected Kir6.2/SUR2B cells and pig bladder strips. Additionally, A-151892 was found to selectively inhibit unstable bladder contractions in vivo in an obstructed rat model of myogenic bladder function. (C) 2003 Elsevier Science Ltd.
