Novel compounds based on la were synthesized with the focus of obtaining agonists acting upon peripheral BRS-3. To identify potent anti-obesity compounds without adverse effects on the central nervous system (CNS), a carboxylic acid moiety and a labile carboxylic ester with an antedrug functionality were introduced. Through the extensive synthetic exploration and the pharmacokinetic studies of intravenous administration in mice, the ester 2b was selected owing to its most suitable pharmacological profile. In the evaluation of food intake suppression in C57BL/6N mice, 2b showed significant in vivo efficacy and no clear adverse effects on blood pressure change in dogs administered the compound by intravenous infusion.
