4-Oxo-Dimeric-Isotretinoin is a derivative of 9-cis-Retinoic Acid (R245000) which is an endogenous retinoic acid isomer, which is capable of binding to both retinoic acid receptors (RAR) and retinoid X receptors (RXR). A biologically active ligand for members of the RAR and RXR subfamilies, implying that it may play a critical role in regulating retinoid-responsive pathways.
