  Synthesis and Structure−Activity Relationships of a Novel Series of 2,3,5,6,7,9-Hexahydrothieno[3,2-b]quinolin-8(4H)-one 1,1-Dioxide K_ATP Channel Openers:  Discovery of (−)-(9S)-9-(3-Bromo-4-fluorophenyl)-2,3,5,6,7,9- hexahydrothieno[3,2-b]quinolin-8(4H)-one 1,1-Dioxide (A-278637), a Potent K_ATP Opener That Selectively Inhibits Spontaneous Bladder Contractions

  摘要：

  Structure-activity relationships were investigated on a novel series of sulfonyldihydropyridine-containing K-ATP openers. Ring sizes, absolute stereochemistry, and aromatic substitution were evaluated for K-ATP activity in guinea pig bladder cells using a fluorescence-based membrane potential assay and in a pig bladder strip assay. The inhibition of spontaneous bladder contractions in vitro was also examined for a select group of compounds. All compounds studied showed greater potency to inhibit spontaneous bladder contractions relative to their potencies to inhibit contractions elicited by electrical stimulation. In an anesthetized pig model of myogenic bladder overactivity, compound 14 and (-)-cromakalim 1 were found to inhibit spontaneous bladder contractions in vivo at plasma concentrations lower than those that affected hemodynamic parameters. Compound 14 showed approximately 5-fold greater selectivity than I in vivo and supports the concept that bladder-selective K-ATP channel openers may have utility in the treatment of overactive bladder.

  from NaIO 4 and either I 2 or KI in concentrated H 2 SO 4 (minimum 95% by weight). In general a small excess of the dark brown iodinating solution was used (1.1/1.5 equivalents, for nitrobenzene two equivalents was required). The iodinations were conducted at 25-30 °C with a reaction time of 1-2 hours using either a 'direct' or an 'inverse' method of aromatic iodination to give mono- or diiodinated pure
