Description and Uses
Bexarotene was launched in the US for the treatment of manifestations of cutaneous T-cell lymphoma in patients who are refractory to at least one prior systemic therapy. The four step synthesis of bexarotene involves a double Friedel-Craft alkylation of toluene with 2,5-dichloro-2,5-dimethylhexane followed by acylation with monomethylterephthalic acid chloride, then Wittig methylidenation. Bexarotene is the first retinoid X receptor (RXR) agonist to be selective versus retinoid A receptors (RAR). Its activation of the three RXRα, β, γ isoforms induces cell differentiation and apoptosis and inhibits cell proliferation in several models of cancer. In phase ll/lll clinical trials, 48% of patients with refractory or persistent early-stage cutaneous T-cell lymphoma achieved a complete or partial response when treated with 300 mg/m2/day of bexarotene. It was shown in phase I trials that this second-generation retinoid was substantially less toxic than the broad-spectrum or RARselective retinoids.
Bexarotene is used as a Synthetic retinoid analog with specific affinity for the retinoid X receptor, an antineoplastic agent, already approved as an oral antineoplastic agent for cutaneous T cell lymphoma and being investigated against other cancers. A study has found that bexarotene in a mouse Alzheimer?s model lowered the most toxic form of β-amyloid peptide and increased cognitive ability.
