epithelial ion transport

GSK137647A (GSK 137647) is a selective agonist of FFA4.

ARN23765 is an F508del-CFTR corrector with an EC50 of 38 pM in human bronchial epithelial cells. It enhances the maturation and function of F508del-CFTR at the cell membrane, influencing ion transport and secretion, thereby addressing the pathological mechanisms of cystic fibrosis (CF).

Butyrylcholine is a novel colonic ion transport regulator produced by colonic epithelial cells that stimulates nicotine and muscarinic receptors.

20-carboxy Arachidonic acid (20-COOH-AA) is the major metabolite of 20-HETE that is produced in renal tubular epithelial, endothelial, and microvascular smooth muscle cell cultures. This ω-oxidation conversion can take place using purified alcohol dehydrogenases three and four or by microsomes containing recombinant human CYP4F3B. Like 20-HETE, 20-COOH-AA inhibits ion transport in the kidneys. It also produces vasorelaxation of porcine coronary microvessels constricted with endothelin. 20-COOH-AA binds to isolated ligand binding domains of peroxisome proliferator-activated receptor α (PPARα) (Kd = 0.87 ± 0.12 μM) and PPARγ (Kd = 1.7 ± 0.5 μM), and is a dual activator of PPARα and PPARγ in a transiently transfected COS-7 cell reporter system.
