9-cis-Retinoic acid (Alitretinoin, ALRT 1057) is an active metabolite of vitamin A that functions as a high-affinity ligand for retinoid X receptors (RXRs) and also activates retinoic acid receptors (RARs). It inhibits adipogenesis by activating RXR while simultaneously decreasing RXRα and PPARγ levels in an RXR activation-independent manner.
