Sodium tauroglycocholate

Sodium tauroglycocholate (CAS No.: 41945-48-6) is a bile salt derived from taurine conjugated bile acid chemistry and is broadly categorized as an amphiphilic biological surfactant and membrane permeability modulator used in pharmaceutical and biomedical research, particularly in drug delivery science, membrane transport studies, and bioanalytical method development. In experimental systems, it functions through physicochemical interactions with lipid and protein assemblies, including modulation of stratum corneum lipid organization, interaction with keratin associated structures, perturbation of epithelial barrier architecture, and micellar or reverse micellar encapsulation effects that can stabilize enzyme microenvironments in nonaqueous settings, thereby supporting mechanistic investigations of protein activity retention and transport behavior. Available evidence supports its use as a research tool for enhancing transmembrane flux of model compounds in in vitro permeation platforms and for probing hepatobiliary transport compatibility in cellular and animal based imaging related workflows, with reported activity generally described at low to moderate concentration ranges consistent with bile salt surfactant behavior, while quantitative potency metrics such as IC50 or EC50 are not consistently standardized for this reagent and are therefore commonly interpreted in context specific micromolar to higher experimental windows. In life sciences workflows, it is typically applied in cell based barrier models, ex vivo skin or membrane diffusion studies, and selected in vivo pharmacokinetic or imaging support experiments to evaluate absorption and transport phenomena, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
