1-Isopropyl-1H-1,2,3-benzotriazole-5-carboxylic acid Structural

What is 1-Isopropyl-1H-1,2,3-benzotriazole-5-carboxylic acid?

Description

IPBT-5CA (306935-41-1) is a highly selective agonist for the human orphan G-protein-coupled receptor GPR109b (EC50 = 400 nM). No activity was reported at the highly homologous high-affinity niacin receptor GPR109a.

What are the applications of Application

IBC 293 is a selective HM74/GPR109b receptor agonist

Definition

ChEBI: 1-propan-2-yl-5-benzotriazolecarboxylic acid is a member of benzotriazoles.

Biological Activity

Highly selective agonist for GPR109B (HM74), the human orphan G-protein-coupled receptor expressed in adipocytes. Selective for GPR109B over closely related niacin receptor GPR109A (HM74A); EC 50 values are 400 nM and > 1 μ M respectively. In vitro, inhibits isoproterenol-stimulated lipolysis in isolated human adipocytes.
