Bexarotene (LGD1069) is a high-affinity and selective retinoid X receptors (RXR) agonist withEC₅₀s of 33, 24, 25 nM forRXRα,RXRβ, andRXRγ, respectively. Bexarotene shows limited affinity for RAR receptors (EC₅₀ >10000 nM)^[1][2][3]. Bexarotene can be used for the research of cutaneous T-cell lymphoma.

Bexarotene selectively binds and activates RXR subtypes with K_d=14±2 nM, 21±4 nM, and 29±7 nM for RXRα, RXRβ, and RXRγ subtypes^[1].
Bexarotene is effective in limiting the proliferation of leukemic (HL-60) cells. Bexarotene inhibits the proliferation of HL-60 cells by 37% at 1 μM^[1].
Bexarotene monotherapy of cells shows an antiproliferative effect at a high dose, and the IC₅₀s aere 40.62±0.45 μM (PC3) and 50.20±4.10 μM (DU145)^[2].
Bexarotene (20 and 40 μM) and Docetaxel (5 and 10 μM) exhibit a synergistic effect on the inhibition of PC3 and DU145 cell proliferation^[2].
Bexarotene (20 and 40 μM) represses cyclin D1 and cyclin D3 expression in PC3 and DU145 cells^[2].

Bexarotene (1 mg/kg/day) is effective in blocking the development of behavioral deficits and dopamine neuron degeneration in a rat model of Parkinson’s disease (PD) producing significantly reduced changes in both triglycerides and T4 serum^[1].
Bexarotene is an effective preventive agent against lung tumor growth and progression. Bexarotene ((100 mg/kg by gavage) inhibits both tumor multiplicity and tumor volume in mice of all three genotypes (p53^wt/wtK-ras^wt/wt, p53^val135/wtK-ras^wt/wt, or p53^wt/wtK-ras^ko/wt). Bexarotene reduces the progression of adenoma to adenocarcinoma by ~50% in both p53^wt/wtK-ras^ko/wt and p53^wt/wtK-ras^wt/wt mice^[3].
