| Use | A selective agonist of retinoid X receptors |
| In vitro study | In CTCL cell lines (MJ,HUT78, and 11h), Bexarotene(1 mM and 10 mM) treatment for 96 H increased cellular subg1 population and annexin V binding in a dose-dependent manner. In CTCL cell lines (MJ,HUT78 and 11h), Bexarotene treatment inhibited the expression of retinoid X receptor α and retinoic acid receptor α proteins. Bexarotene treatment reduces survival protein levels, activates caspase-3 and cleaves poly (ADP-ribose) polymerase, however, there was no significant effect on the expression of Fas/ Fas ligand and bcl-2 protein in these three cells.

| In vivo study | In animal models, Bexarotene significantly prevents ER-negative breast tumor formation with lower toxicity than naturally occurring retinoids. In MMTV-erbB2 mice, Bexarotene inhibits the development of pre-invasive breast lesions such as hyperplasia and carcinoma. |

SR 11247 - Preparation Method
Open Data Verified Data
aluminum trichloride was suspended in 1,2-= ethyl chloride, and 1.2,3,4-tetrahydro-1 was added at room temperature under protection of ammonia gas. 1,4,4,6-pentamethylnaphthalene and 1,2-= chloroethyl ether containing 4-methoxycarbonyl benzoyl chloride, stirred. Ice water was added and extracted with ethyl acetate in hexane. The extract was washed with saturated sodium bicarbonate and brine, dried, filtered and concentrated, and the obtained compound was obtained by column chromatography [4-(5,6,7, 8-tetrahydro-3, 5,5,8,8-pentamethyl-2-aryl) carbonyl] benzoic acid methyl ester. To a suspension of methyltriphenylphosphine bromide in benzene was added a solution of potassium hexamethyldisilazide in toluene at room temperature and under protection with ammonia, and the mixture was stirred. Add a benzene solution containing methyl [4-(5,6,7, 8-tetrahydro-3, 5,5,8, 8-pentamethyl-2-naphthyl) carbonyl] benzoate, stir at room temperature. It was then filtered through silica gel and washed with ethyl acetate in hexane. The filtrate was concentrated and the obtained substance was subjected to column chromatography to obtain 4-[1-(5,6,7.8-tetrahydro-3, 5,5,8,8-pentamethyl-2-naphthyl)-1-vinyl] benzoic acid methyl ester. This compound was suspended in aqueous methanol, potassium hydroxide was added, cooled to room temperature, acidified with hydrochloric acid, and extracted with ethyl acetate in hexane. The extract was dried, concentrated and recrystallized from dichloromethane-hexane to obtain beasarodine.

SR 11247 - Use
Open Data Verified Data
It was developed by Ligand Pharmaceutical Company of the United States and was first listed in the United States on January 15, 2000. Retinoid agonists. The product can selectively bind to and activate retinoic acid class X receptor subtypes (RXRa, RBP, RXR7). RXR can form a heterodimer with a variety of receptors, such as vitamin A receptor (RAR), vitamin D receptor, thyroxine receptor. It is used as a topical treatment for skin lesions in patients with refractory early stage cutaneous T-cell lymphoma (CTCL), or in patients with lymphoma who have failed other treatments.

SR 11247 - Reference Information
| Pharmacological effects | Besarodin has an inhibitory effect on lung and breast tumors. The side effects are hypertriglyceridemia and hypercholesterolemia. The researchers optimized the formulation of sprayed bezarotin using a clinically relevant solvent system. The optimized preparation has good chemoprevention effect on lung squamous cell carcinoma and lung adenocarcinoma mouse models, and does not cause obvious toxic symptoms, nor does it increase plasma triglyceride or cholesterol concentration. Nebulized bezarodin can be evenly distributed in the lung parenchyma of mice and regulate the microenvironment in vivo by increasing the number of tumor infiltrating T cells. RNA sequencing of lung cancer cell lines shows that bezarotin can regulate various pathways of cancer. |
| biological activity | Bexarotene (Targretin, LGD1069) is a retinoic acid, which specifically selectively acts on retinoic acid X receptor and is used as an oral anti-tumor drug to treat cutaneous T-cell lymphoma. |
