Description：LXR-623 is a brain-penetrant partial LXRα and full LXRβ agonist, with IC50s of 24 nM and 179 nM, respectively.

In Vitro：LXR-623 potently kills U87EGFRvIII and GBM39 cells in vitro while completely sparing NHAs. LXR-623 also increases ABCA1 protein and decreases LDLR protein levels in all three cell lines. LXR-623 suppresses LDLR expression, increases expression of the ABCA1 efflux transporter, and induces substantial cell death in all of the GBM samples tested. LXR-623 (5 μM) also induces GBM cell death through activation of LXRβ[1]. LXR-623 treatment of human PBMC in vitro significantly increases transcription of ABCA1 and ABCG1[4].

In Vivo：LXR-623 (400 mg/kg, p.o.) crosses the blood-brain barrier, induces target gene expression, and achieves therapeutic levels in GBM cells in the brain with minimal activity in the periphery. LXR-623 inhibits tumor growth, promotes tumor cell death, and prolongs the survival of mice bearing intracranial patient-derived GBMs[1]. LXR-623 (1.5, 5 mg/kg/day) significantly reduces progression of atherosclerosis in animals compared with the placebo group[2]. WAY-252623 (15 and 50 mg/kg) results in a significant reduction of atherosclerosis in a dose-dependent manner. WAY-252623 (20, 60, and 120 mg/kg/day, p.o.) displays neutral lipid effects in this CETP-expressing Syrian hamster[3]. Moreover, LXR-623 (50 mg/kg) induces gene expression in rodent peripheral blood cells in rat. LXR-623 (0, 15 and 50 mg/kg) dose-dependently upregulates transcription of ABCA1 and ABCG1 in monkey whole blood cells proportional to dose[4].

Animal Administration：Five-week-old female athymic nu/nu mice are used in the experiment. A total of 1×105 U87EGFRvIII IRFP720 or GBM39 IRFP720 cells in 5 μL of PBS is intracranially injected into the mouse brain. Tumors are allowed to establish over the course of 7-10 days and engraftment of tumors is quantitatively confirmed via FMT signal intensity. Tumor growth is monitored using an FMT 2500 fluorescence tomography system. For drug treatment studies, vehicle (0.5% methylcellulose, 2% Tween 80 in water) or LXR-623 (400 mg/kg) resuspended in vehicle are administered to mice via oral gavage daily starting at day 7 postinjection.
