bexarotene

Bexarotene (LGD1069) is a retinoid analogue that is used to treat the skin manifestations of cutaneous T cell lymphoma (CTCL).

Bexarotene D4 is a deuterium-labeled Bexarotene (LGD1069). Bexarotene is a selective RXR agonist used in the treatment of cutaneous T-cell lymphoma.

6-Hydroxy Bexarotene, an oxidative metabolite of bexarotene, serves as a high-affinity ligand for retinoid X receptors (RXRs), specifically binding to RXRα, RXRβ, and RXRγ, as well as to the retinoic acid receptor α (RARα) with dissociation constants (Kds) of 3.46, 4.21, 4.83, and 8.17 μM, respectively. It demonstrates selective activation of RXRα, RXRβ, and RXRγ over RARα, RARβ, and RARγ in vitro, with half-maximal effective concentrations (EC50s) of 398, 356, 420, 4,414, 2,121, and 2,043 nM, respectively.

Fluorobexarotene possesses an apparent RXR binding affinity that is 75% greater than Bexarotene. Fluorobexarotene  is a potent retinoid-X-receptor (RXR) agonist, with a Ki value of 12 nM and an EC50 value of 43 nM for RXRα receptor. Fluorobexarotene possesses an apparent RXR binding affinity that is 75% greater than Bexarotene.

OAB-14 is a Bexarotene derivative that improves Alzheimer's disease-related pathologies and cognitive impairments by increasing β-amyloid clearance in APP/PS1 mice. OAB-14 effectively ameliorates the dysfunction of the endosomal-autophagic-lysosomal(EAL) pathway in APP/PS1 transgenic mice [1] [2].
