Relationship between Stereochemistry and the β<sub>3</sub>-Adrenoceptor Agonistic Activity of 4‘-Hydroxynorephedrine Derivative as an Agent for Treatment of Frequent Urination and Urinary Incontinence
were synthesized via oxazolidinone prepared by intracyclization involving inversion of the beta-hydroxy group. The in vitro assays using rat atria for beta(1)-AR, rat uteri for beta(2)-AR, and ferret detrusor for beta(3)-AR showed that 1a possessed potent beta(3)-AR agonistic activity (EC(50) = 3.85 nM) and 3700- and 1700-fold selectivity for beta(3)-AR relative to beta(1)- and beta(2)-AR, respectively
