L-755, 507 was previously characterized as a potent and selective β3 adrenergic receptor partial agonist with EC50 ~0.43 nM. It has > 1000 fold selectivity overβ1- and β2-adrenoceptors (EC50 ~ 580 nM and >10000 nM forβ1- and β2-adrenoceptors respectively). It stimulates lipolysis in rhesus adipocytes in vitro (EC50 = 3.9 nM). In a recent study, L-755, 507 was identified to enhance CRISPR-mediated homology-directed repair (HDR) efficiency in human induced pluripotent stem cells (iPSCs) and other cell types.
