Scaffold Hopping Provides Liver X Receptor Agonist With Preference for the β Subtype

open access: yesChemMedChem, Volume 21, Issue 19, 14 October 2026.
A scaffold hopping strategy was pursued to enhance the binding pocket engagement and β‐subtype selectivity of liver X receptor agonist 2. The resulting spirocyclic lead compound, (S)‐7, demonstrates superior potency, enhanced potency‐based selectivity for LXRβ, and improved microsomal stability over the existing scaffold.
