Tambulin is an orally active flavonol compound found in Zanthoxylum armatum. Tambulin can inhibit cell proliferation, induce apoptosis and inhibit ROS production. Tambulin upregulates cleaved caspase-3, cleaved caspase-9, and Bax, downregulates Bcl-2 levels. Tambulin can stimulate glucose-dependent insulin secretion and induce endothelium-independent vasorelaxation. Tambulin binds to succinate dehydrogenase (SDH) (Ki = 11.02 μM) and shows significant ferric reducing power. Tambulin can enhances oxidative stress resistance, reduces, lipofuscin deposits, lipid levels, α-synuclein levels, improves locomotary behavior, and dopamine levels in in age-synchronized L1 hermaphrodite Caenorhabditis elegans models of ageing and Parkinson's disease. Tambulin can be used for the researches of Parkinson's disease, lung squamous cell carcinoma, and diabetes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
