3-chloro-5-hydroxy BA is a GPR81 agonist.

GPR81 (HCA1) is a member of G-protein-coupled receptors (GPCRs). GPR81 is predominantly expressed on adipocytes and is activated by the endogenous ligands 2-hydroxypropanoate (lactate). Stimulation of GPR81 in adipose tissue lead to a decrease in the lipolysis of triglycerides by hormone-sensitive lipase, which resulted in reduced transport of fatty acids to the liver and a decrease in hepatic triglycerides [1].

In vitro: In the hGPR81 assay, 3-chloro-5-hydroxybenzoic acid showed the potency against GPR81 with an EC50 of 16 μM. The EC50 of 3-chloro-5-hydroxybenzoic acid against monkey GPR81, dog GPR81, rat GPR81, mouse GPR81, and hamster GPR81 was 17 μM, 67 μM, 7 μM, 22 μM and 27 μM, respectively [1]. 3-chloro-5-hydroxy BA blocked basal ghrelin secretion by primary gastric mucosal cells [2].

In vivo: In mice, oral administration of 3-chloro-5-hydroxybenzoic acid at 30 mg/kg provided a Cmax of 67 μM at approximately 3-fold over the in vitro EC50 with an AUCinf of 54 h μM and a short t1/2 of 1.5 h, and the 100 mg/kg p.o dose attained a Cmax of 342 μM at greater than 15-fold over the observed in vitro EC50 [1].
