Background:

D-Kynurenine is an antagonist of hydroxycarboxylic acid receptor 3 HCA3/GPR109B (EC50 = 2.61 μM in a luciferase reporter assay) and a metabolite of D-tryptophan.1 It increases levels of intracellular calcium and decreases forskolin-stimulated production of cAMP in CHO cells expressing human HCA3/GPR109B when used at concentrations of 10 and 100, or 1,000 μM, respectively. D-Kynurenine (10 μM) increases expression of vimentin and decreases expression of E-cadherin in 95D lung cancer cells.2 It has been used as a substrate in fluorometric assays for D-amino acid oxidase activity.3,4
