LXR-623
LXR-623 is an agonist of liver X-receptor with IC50 values of 179nM and 24nM for LXR-α and LXR-β, respectively [1].
LXR-623 is a partial agonist of LXR which regulates the transcription of genes involved in cellular cholesterol homeostasis. As the LXR agonist, LXR-623 is used to enhance reverse cholesterol transport through up-regulating cholesterol transporters. To rodents, orally dosed LXR-623 increases the transcription level of ABCA1 and ABCG1 in peripheral blood cells. To human, LXR-623 also significantly increases ABCA1 and ABCG1 both in PBMC cells and in T- and B-cells. In addition, in mouse model of atherosclerosis, LXR-623 is found to up-regulate intestinal ABCG5 and ABCG8. In cynomolgus monkeys, LXR-623 up-regulates ABCA1 and ABCG1 in whole blood. Besides that, LXR-623 is proposed to be used in treatment of Alzheimer’s disease since it can lower the level of amyloid-βin brain [1, 2].
