Background

Tocofersolan is a nonionic surfactant and derivative of vitamin E.¹ It has a critical micelle concentration (CMC) of 0.02 mM at room temperature. Tocofersolan inhibits P-glycoprotein (P-gp), also known as multidrug resistance protein 1 (MDR1), substrate-induced ATPase activity in cell-free assays (IC₅₀s = 0.4-3.25 ?M).² It reverses locomotor deficits induced by the polycyclic aromatic hydrocarbon benzo[a]pyrene in zebrafish larvae when used at a concentration of 1 ?M.³ Intravenous administration of nanocrystals containing tocofersolan (50 mg/kg) and paclitaxel reduces tumor growth in an NCI/ADR-RES mouse xenograft model.⁴
