Abstract :

Retinoid X receptor-alpha (RXRα) is implicated in the regulation of many biological processes and also represents a unique intracellular target for pharmacologic interventions. Efforts on discovery of small molecules targeting RXRα have been primarily focused on the molecules that bind to its classical ligand-binding pocket (LBP). Using structure-based approach and in collaboration with a multi-disciplinary team, we have identified novel RXRα modulators that use new binding mechanisms to mediate the biological functions of RXRα. The new compounds can effectively suppress AKT activation and promotes apoptosis of cancer cells in a RXRα-dependent manner by inhibiting the interaction between a truncated RXRα and the p85α subunit of PI3K.
