Biological Activity: Carboxymethyl-β-cyclodextrin sodium salt is a negatively charged β-cyclodextrin derivative, as well as a metal ion chelator and solubilizing reagent. Carboxymethyl-β-cyclodextrin sodium salt forms stable aqueous complexes with Ba²⁺, Ca²⁺, Cd²⁺, Ni²⁺, Pb²⁺, Sr²⁺, and Zn²⁺ ions. Carboxymethyl-β-cyclodextrin sodium salt derived hydrogel carriers support oral insulin delivery via paracellular permeation across Caco-2 monolayers and produce sustained hypoglycemic effects in diabetic mice. Carboxymethyl-β-cyclodextrin sodium salt can be conjugated onto folate-modified BSA nanoparticles to boost folate receptor-mediated endocytosis, elevate intracellular anticancer drug uptake and trigger cell apoptosis. Carboxymethyl-β-cyclodextrin sodium salt can be utilized for chiral separation in capillary electrophoresis, development of nanoscale drug carriers and nucleic acid transfection research^[1][2][3].
