3-CHLORO-5-HYDROXY-BENZOIC ACID Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
GPR81, also known as hydroxycarboxylic acid receptor 1 (HCAR1), is a recently de-orphanized receptor that is activated by lactic acid (EC50 ~ 1.5 mM) but not by other hydroxycarboxylic acids. 3-chloro-5-hydroxy Benzoic Acid (3-chloro-5-hydroxy BA) is an agonist of GPR81 (EC50 = 16 μM) that is inactive against the related GPR109a (HCAR2) receptor. It is similarly effective at GPR81 receptors from a variety of mammalian species and is bioavailable, stimulating lipolysis (increased serum free fatty acids) in mice fed high fat chow for 10 weeks. 3-chloro-5-hydroxy BA, like lactate, blocks basal ghrelin secretion by primary gastric mucosal cells.[Cayman Chemical]
Verwenden
5-Chloro-m-salicylic Acid was studied as a potential selective lactate receptor (GPR81) agonists with antilipolytic effects.
Biologische Aktivität
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].
