Pan-RAR Agonist/AP-1 Inhibitor LGD 1550

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** An orally-active synthetic aromatic retinoic acid agent with potential antineoplastic and chemopreventive activities. LGD 1550 selectively binds to all three retinoic acid receptors (RAR-alpha, RAR-beta, and RAR-gamma), resulting in alterations in the expression of genes responsible for cell differentiation and proliferation. This agent also acts as an inhibitor of activator protein 1 (AP-1), a protein that mediates trophic responses and malignant transformation. (NCI04)
