WebFeb 1, 2024 · Biotin has been used as an appropriate targeting agent because biotin receptors overexpressed on the surface of different cancer cells can target biotin into these cells [ 37 ]. Excitingly, a novel strategy for designing next-generation anticancer metal agents involves combining metal ion and ligand with anticancer activity [8, 26, 31 ]. WebBiotin is a coenzyme for carboxylase enzymes and biotin is required for the synthesis of these molecules: fatty acids, isoleucine, and valine. Biotin is also involved in gluconeogenesis. Once biotin is attached to a molecule, the biotin tag can be used to facilitate affinity purification of that molecule using an immobilized biotin-binding protein.
