Cryptotanshinone (Tanshinone C)

製品コード：S2285 純度：99.75%

Cryptotanshinone (Tanshinone C) is a STAT3 inhibitor with IC50 of 4.6 μM in a cell-free assay, strongly inhibits phosphorylation of STAT3 Tyr705, with a small effect on STAT3 Ser727, but none against STAT1 nor STAT5. Cryptotanshinone induces ROS-dependent autophagy and mitochondria-mediated apoptosis.

STAT3 ^[1]
(HCT-116 cells)

4.6 μM

In Vitro
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]
Kinase Assay	STAT3-dependent dual-luciferase assay
Kinase 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.

	濃度	Dissolved in DMSO, final concentrations ~50 μM
	反応時間	24 or 48 hours
	実験の流れ	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.

In Vivo
In Vivo	Cryptotanshinone administration significantly reduces the body weight and food intake of ob/ob mice (C57BL/6J-Lep^ob) 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-Lep^ob), db/db mice (C57BL/KsJ-Lepr^db), and ZDF rats, which occur after 3 days and persist over the entirety of the monitoring period. ^[2]

よくある質問（FAQ）

質問1:
I want to use this compound for my mouse in vivo experiment, so how to reconstitute it?

回答
Cryptotanshinone can be dissolved in 2% DMSO/30% PEG 300/5% Tween 80/ddH2O at 2 mg/ml. But after stayed for about 0.5-1 hour, the precipitation went out. So if you are going to use this vehicle, it is recommended to be prepared just before use.
