Binds preferentially to double-stranded oligonucleotide direct repeats having the consensus half-site sequence 5'-AGGTCA-3' and 4-nt spacing (DR-4). Regulates cholesterol uptake through MYLIP-dependent ubiquitination of LDLR, VLDLR and LRP8 (By similarity). Publication Abstract from PubMed Discovery and optimization of selective liver X receptor beta (LXRbeta) agonists are challenging due to the high homology of LXRalpha and LXRbeta in the ligand-binding domain. There is only one different residue (Val versus Ile) at the ligand-binding pocket of LXRs. With machine learning methods, we identified pan LXR agonists with a novel scaffold (spiro[pyrrolidine-3,3'-oxindole]). Then, we figured out the mechanism of LXR isoform selectivity from co-crystal structures. Based on the mechanism and the new scaffold, LXRbeta selective agonists were designed and synthesized. This led to the discovery of LXRbeta agonists 4-7rr, 4-13 and 4-13rr with IC50 values ranging from 1.78 to 6.36 muM against glioblastoma in vitro. Treatment with 50 mg/kg/day of 4-13 for 15 days significantly reduced tumor growth using an in vivo xenograft glioblastoma model.
