  Discovery and structure–activity relationships of a novel series of benzopyran-based KATP openers for urge urinary incontinence

  摘要：

  A novel series of benzopyran derivatives were synthesized and evaluated as K(ATP) channel openers. Structure-activity relationships were investigated around 4-position of the benzopyran nucleus. Optimization of 4-substituent with some heterocyclic rings led to compound 13b bearing a benzo[d] isoxazol-3-one moiety as a potent and selective KATP channel opener in vitro. In two anesthetized rat models of myogenic bladder overactivity, compound 13b was found to inhibit spontaneous bladder contractions. (C) 2008 Elsevier Ltd. All rights reserved.
