Jolkinolide B is a bioactive diterpene isolated from the roots of Euphorbia fischeriana Steud with oral activity. Jolkinolide B downregulates XIAP, cIAP1, cIAP2, and phosphorylated Akt, upregulates Smac, activates caspase-3 and caspase-9, and inhibits NF-κB, TGFβ/smad3 and JAK/STAT3 pathways. Jolkinolide B exerts comprehensive biological effects including inducing cancer cell apoptosis, suppressing inflammatory responses, improving lung function, alleviating hepatic steatosis and eliminating intracellular Mycobacterium tuberculosis. Jolkinolide B can be used for the research of leukemia, histiocytic lymphoma, asthma, metabolic dysfunction-associated steatotic liver disease and tuberculosis.

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.
