β2AR agonist 2

β2AR agonist 2 (compound 8a) is an agonist of the β2-adrenergic receptor (β2AR). It is a saturated azacyclic compound featuring a 4- to 7-membered heterocycle. The compound has a chiral structure in the -R form by incorporating a carbon with a requisite hydroxyl group, which significantly stimulates glucose uptake in skeletal muscle cells, thereby enhancing cellular glucose uptake (GU). β2AR agonist 2 is applicable in the study of type 2 diabetes (T2D).
