Hydroxycarboxylic acid receptors

Formerly known as: Nicotinic acid receptor family

Overview

« Hide More detailed introduction

The hydroxycarboxylic acid family of receptors (ENSFM00500000271913, nomenclature as agreed by NC-IUPHAR Subcommittee on Hydroxycarboxylic acid receptors, [7]) respond to organic acids, including the endogenous hydroxy carboxylic acids 3-hydroxy butyric acid and L-lactic acid, as well as the lipid lowering agents nicotinic acid (niacin), acipimox and acifran [10,14-15]. These receptors were provisionally described as nicotinic acid receptors, although nicotinic acid shows submicromolar potency at HCA2 receptors only and is unlikely to be the natural ligand [14-15].
