Biological Activity for (R)-Shikonin
(R)-Shikonin is a PTEN and inflammasome inhibitor. Inhibits PTEN's phosphatase activity (IC50 = 2.7 μM) and NLRP3 activation. Also blocks TNF-α and NF-κB signaling. Attenuates HIV-1 replication at nanomolar concentrations. Suppresses glycolysis in cancer cells by inhibiting tumor-specific pyruvate kinase M2 (PKM2) (IC50 = 0.3 μM). Induces necroptosis in MCF-7 and HEK293 cancer cell lines. Displays anti-inflammatory activity in a mouse model of collagen-induced arthritis.
