Cardioselective Antiischemic ATP-Sensitive Potassium Channel (KATP) Openers. 6. Effect of Modifications at C6 of Benzopyranyl Cyanoguanidines
摘要:
The effect on potency and selectivity of modifications at the C6 position of the cardioprotective K-ATP Opener BMS-180448 (2) is described. Structure-activity studies show that a variety of electron-withdrawing groups (ketone, sulfone, sulfonamide, etc.) are tolerated for cardioprotective activity as measured by EC25 values for an increase in time to the onset of contracture in globally ischemic rat, hearts. Changes made to the sulfonamido substituent indicate that compounds derived from secondary lipophilic amines are preferred for good cardioprotective potency and selectivity. The diisobutyl analogue 27 (EC25 = 0.04 mu M) is the most potent compound of this series. The cardiac selectivity of 27 results from a combination of reduced vasorelaxant potency and enhanced cardioprotective potency relative to the potent vasodilating K-ATP openers (e.g., cromakalim). The diisobutylsulfonamide analogue 27 is over 4 orders of magnitude more cardiac selective than cromakalim (1), These results support the hypothesis that the cardioprotective and vasorelaxant properties of K-ATP openers follow distinct structure-activity relationships. The mechanism of action of 27 appears to involve opening of the cardiac K-ATP as its cardioprotective effects are abolished by the K-ATP blocker glyburide.

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.
