Biological Activity
Description Cryptotanshinone (CPT) is a STAT3 inhibitor with IC50 of 4.6 μM.
Targets STAT3
IC50 4.6 μM [1]
In Vitro Cryptotanshinone, a natural compound isolated from the roots of Salvia miltiorrhiza Bunge (Danshen), significantly inhibits STAT3-dependent luciferase activity, the STAT3 Tyr705 phosphorylation and the dimerization of STAT3, compared to tanshinone IIA which exhibits no activity. Cryptotanshinone (7 μM) dramatically blocks STAT3 Tyr705 phosphorylation but not STAT3 Ser727 phosphorylation in DU145 cells, and significantly inhibits JAK2 phosphorylation with IC50 of ~5 μM without affecting the phosphorylation of upstream kinases c-Src and EGFR, suggesting the inhibition of STAT3 Tyr705 phosphorylation might due to a direct mechanism probably by binding to the SH2 domain of STAT3. Cryptotanshinone significantly inhibits the proliferation of DU145 prostate cancer cells harboring constitutively active STAT3 with GI50 of 7 μM by blocking STAT3 activity, which leads to the down-regulation of cyclin D1, Bcl-xL, and survivin, subsequently the accumulation in the G0-G1 phase. Cryptotanshinone exhibits less growth inhibitory effect on PC3, LNCaP and MDA-MB-468 cells. [1]
In Vivo Cryptotanshinone administration significantly reduces the body weight and food intake of ob/ob mice (C57BL/6J-Lepob) and diet-induced obese (DIO) mice in a dose-dependent manner. Cryptotanshinone causes noticeably less fat in the adipose tissues, significant reductions of serum triglycerides and cholesterol levels, and 2.5- to 3-fold higher AMPK activity of the skeletal muscles than in the control mice. Oral administration of Cryptotanshinone at 600 mg/kg/day produces dramatic reductions in blood glucose levels of ob/ob mice (C57BL/6J-Lepob), db/db mice (C57BL/KsJ-Leprdb), and ZDF rats, which occur after 3 days and persist over the entirety of the monitoring period. [2]
Clinical Trials A clinical study to determine whether Cryptotanshinone may prove effective in eradicating Polycystic Ovary Syndrome (PCOS) symptomatology is ongoing.
Features
Protocol
Kinase Assay [1]
STAT3-dependent dual-luciferase assay HCT-116 cells are transiently transfected with reporter plasmid having the STAT3-binding element for regulating luciferase assay. Cells are treated with Cryptotanshinone for 24 hours at a concentration range of 0.2 to 50 μM. After treatment, cells are harvested in 20 μL of passive lysis buffer and luciferase activity is evaluated by the Dual Luciferase Reporter Assay kit on Wallac Victor2. The concentration of Cryptotanshinone that inhibits the luciferase activity by 50% represents IC50 value.
Cell Assay [1]
Cell Lines KATO III, DU145, PC3, LNCaP, MDA-MB-231, MDA-MB-468, MDA-MB-453, MCF-7, MCF-10A, HeLa and HCT-116
Concentrations Dissolved in DMSO, final concentrations ~50 μM
Incubation Time 24 or 48 hours
Methods Cells are exposed to Cryptotanshinone for 24 or 48 hours. For the determination of cell proliferation, the cell proliferation reagent WST-1 is added and WST-1 formazan is quantitatively measured at 450 nm using an ELISA reader.
Animal Study [2]
Animal Models Zucker Diabetic Fatty (ZDF) (male) type 2 diabetic rat, ob/ob mice (C57BL/6J-Lepob), db/db mice (C57BL/KsJ-Leprdb) and male C57BL/6J mice with high-fat diet-induced obesity
Formulation Dissolved in 0.1% solution of sodium lauryl sulfate
Doses ~600 mg/kg/day
Administration Orally

Biochem/physiol Actions
Cryptotanshinone is an antibacterial and anti-inflammatory compound originally extracted from the roots of Salvia miltiorrhiaz (danshen). Cryptotanshinone has been found to inhibit HIF activation1 and to inhibit macrophage migration negatively regulate the PI3K pathway.2,3 It has demonstrated activity against several strains of Staphylococcus aureus.4

Biochem/physiol Actions
Cryptotanshinone is a quinoid diterpene isolated from the root of the Asian medicinal plant, Salvia miotiorrhiza bunge. Recently it was discovered that the compound is a potent STAT3 inhibitor. Cryptotanshinone rapidly inhibited STAT3 Tyr705 phosphorylation through a JAK2-independent mechanism. Cryptotanshinone selectively inhibits STAT3-activated cell lines through binding to monomer STAT3, subsequently blocking the dimerization and inhibiting STAT3 transcriptional regulatory activity. Previously, it was reported that the compound counteracts inflammation through the inhibition of cyclooxygenase II activity and endothelin-1 expression. In traditional oriental medicine dried roots of Salvia Miltiorrhiza Bunge (Danshen) have commonly been used for the treatment of circulatory disorders, liver disease, coronary heart disease, hepatitis, and chronic renal failure.
