描述 | LXRs (Liver X receptors) are ligand-activated transcription factors of the nuclear receptor superfamily, consist of two LXR isoforms termed alpha and beta. It is characterized as key transcriptional regulators of lipid and carbohydrate metabolism. LXR-623 is a brain permeable synthetic ligand for LXRs with IC50 values of 179 and 24 nM for LXRα and LXRβ, respectively. LXR-623 could upregulate the expression of LXR target gene ABCA1 and stimulate cholesterol efflux with EC50 values of 0.3–1.2 uM in acLDL- loaded foam cell macrophages. Dose of LXR-623 at 15 mg/kg for 8 weeks resulted in a significant reduction of atherosclerotic lesion by 37% in high fat diet mice[1]. Treatment with 2μM LXR-623 for 16h significantly increase the expression of LXR target gene ABCA1, ABCG1 and PLTP in human PBMCs[2]. The highly brain permeability of LXR-623 facilitated its therapeutic in brain cancers. Treatment with LXR-623 at concentration of 2.5μM and 5μM for 3 or 5 days selectively killed GBM cells in an LXRβ- and cholesterol-dependent fashion. Daily oral administration of LXR-623 at 400 mg/kg for 5 weeks inhibited tumor growth, promoted tumor cell death, and prolonged the survival of mice bearing intracranial patient-derived GBMs[3]. |
