Alitretinoin, or 9-cis-retinoic acid, is a form of vitamin A. It is also used in medicine as an antineoplastic (anti-cancer) agent developed by Ligand Pharmaceuticals. Alitretinoin (9-cis-retinoic acid) is a naturally-occurring endogenous retinoid indicated for topical treatment of cutaneous lesions in patients with AIDS-related Kaposi's sarcoma. Alitretinoin inhibits the growth of Kaposi's sarcoma (KS) cells in vitro. Alitretinoin binds to and activates all known intracellular retinoid receptor subtypes (RARa, RARb, RARg, RXRa, RXRb and RXRg). Once activated these receptors function as transcription factors that regulate the expression of genes that control the process of cellular differentiation and proliferation in both normal and neoplastic cells. In the United States, topical alitretinoin (in the form of a gel; trade name Panretin) is indicated for the treatment of skin lesions in AIDS-related Kaposi's sarcoma.

VTP-194204 (NRX 194204, IRX4204) is a second-generation retinoid X receptor (RXR) agonist that has no cross-reactivity with retinoic acid receptors, farnesoid X receptor, liver X receptors or peroxisome proliferator-activated receptor PPARγ. Rexinoid NRX 194204 selectively binds to and activates RXRs. Because RXRs can form heterodimers with several nuclear receptors (NRs), RXR activation by this agent may result in a broad range of gene expression depending on the effector DNA response elements activated. Rexinoid NRX 194204 may inhibit the tumour-necrosis factor (TNF)-mediated release of nitric oxide (NO) and interleukin 6 (IL6) and may inhibit tumour cell proliferation. This agent appears to be less toxic than RAR-selective ligands. VTP-194204 (IRX-4204) is in phase II clinical trials by Io Therapeutics for the treatment of prostate cancer. It is also in preclinical trials for the treatment of Alzheimer's disease, autoimmune diseases and multiple sclerosis.

HX630 is a synthetic RXR pan-agonist. HX-630 has bein shown to exert anti-proliferative and pro-apoptotic effects in murine pituitary corticotroph tumor AtT20 cells, making HX-630 a new therapeutic candidate for Cushing’s disease. It might also serve as potential pharmacological tool for treating retina degenerative diseases and Alzheimer's disease.
