Bexarotene (Ro26-445; LGD-1069; SR-11247; Ro-26 445; Targretin Ro 26-44) is a synthetic retinoid analog and selective agonist of RXR-retinoid X receptors with potential anticancer chemopreventive, teratogenic and embryotoxic properties. Bexarotene has been approved as an oral anticancer agent for the treatment of cutaneous T-cell lymphoma. Bexarotene selectively binds to and activates retinoid X receptors, thereby inducing changes in gene expression that lead to cell differentiation, decreased cell proliferation, apoptosis of some cancer cell types, and tumor regression.
ln Vitro |
Bexarotene preferentially binds and activates RXR isoforms with Kd=14±2 nM, 21±4 nM and 29±7 nM for RXRα, RXRβ and RXRγ isoforms [1]. Bexarotene efficiently reduces the proliferation of leukemia (HL-60) cells. Bexarotene inhibits HL-60 cell proliferation by 37% at 1 μM [1]. Bexarotene treated cells as a single agent displayed anti-proliferative effects at high doses, with IC50s of 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) show synergistic effects on the suppression of PC3 and DU145 cell growth [2]. Bexarotene (20 and 40 μM) suppresses cyclin D1 and cyclin D3 expression in PC3 and DU145 cells [2].

ln Vivo |
In a rat model of Parkinson's disease (PD), bexarotene (1 mg/kg/day) effectively prevents the development of behavioral deficits and dopamine neuron degeneration, thereby significantly reducing changes in serum T4 and triglycerides [1]. One medication that works well at stopping the development and spread of lung tumors is bexarotene. In mice of all three genotypes (p53wt/wtK-raswt/wt, p53val135/wtK-raswt/wt, or p53wt/wtK-rasko/wt), bexarotene (100?mg/kg by gavage) inhibits tumor diversity and tumor volume. Bexarotene decreased the progression of adenoma to adenocarcinoma in p53wt/wtK-rasko/wt by about 50%. and mice that were p53wt/wtK-raswt/wt [3].

Cell Assay |
Cell Proliferation Assay[2]
Cell Types: The human PCa androgen-independent cell lines PC3 and DU145 Tested Concentrations: 5, 10, 20, 30, 40 μM for PC3 cells; 1, 5, 10, 20, 40 μM for DU145 cells. Incubation Duration: 24 and 48 hrs (hours) Experimental Results: demonstrated an antiproliferative effect with the IC50s were 40.62±0.45 µM (PC3) and 50.20±4.10 µM (DU145). Cell Viability Assay[2] Cell Types: PC3 and DU145 cells Tested Concentrations: 20 and 40 µM Incubation Duration: 24 or 48 hrs (hours) Experimental Results: diminished cyclin D1, and cyclin E2 after 24 hrs (hours) treatment. Not only diminished the expression of cyclin D1 and cyclin E2 but repressed cyclin B1 and CDK1 expression after 48 hrs (hours) treatment. |

Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
