• Canonical SMILES: CCOC(=O)C=C(C)C=CC=C(C)C=CC1=C(CCCC1(C)C)C
• Isomeric SMILES: CCOC(=O)/C=C(\C)/C=C/C=C(/C)\C=C\C1=C(CCCC1(C)C)C
• Uses: Ethyl 9-cis-retinoate 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.
