5-Fluoro- and 8-fluorotrimetoquinol: selective .beta.2-adrenoceptor agonists
摘要:
The 5-fluoro and 8-fluoro analogues of trimetoquinol, TMQ, have been synthesized and evaluated for beta 2- and beta 1-adrenoceptor activity in guinea pig trachea and atria, respectively. The fluoro analogues of TMQ maintained potent beta 2-adrenoceptor agonist activity but had reduced beta 1-adrenoceptor agonist activity. The changes in beta 1-activity of these compounds were correlated to differences in phenolic pKa's. The beta 1- and beta 2-adrenoceptor actions of 2 and 3 were blocked in a competitive manner by propranolol. The enhanced beta 2/beta 1 selectivity for the analogues was found to be 8-fluoro analogue 3 greater than 5-fluoro analogue 2 greater than trimetoquinol (1).
