Cryptotanshinone 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 appr 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]. Cryptotanshinone significantly attenuates the in vitro hormonal effects of DEX on ovaries, as indicated by a significant decrease in T and an increase in P levels in the culture medium. Cryptotanshinone significantly increases the levels of phosphorylated AKT2 and GSK3β in the DEX-treated ovaries[2]. Cotreatment with imatinib and Cryptotanshinone shows a significant synergistic killing effect in both imatinib sensitive and resistant CML cell lines, as well as primary CML cells[3].

Detection of protein changes in STAT3 activity, FOXM1 and ATG7 levels, induced by icotinib in indicated cells with or without the treatments of IL-6 (10 ng/mL; 24 h) or Cryptotanshinone (CNT) (7 μM; 24 h). The results showed that Cryptotanshinone (CNT) remarkably inhibited the activation of STAT3 and abrogated the levels of FOXM1 and ATG7 during icotinib treatment.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 0.83 mg/mL (2.80 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 0.83 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.83 mg/mL (2.80 mM); Clear solution
This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
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.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The MTT assay is used for the assessment of cell growth inhibition as described previously. Cells are seeded at a density of 8000 cells per well in 96-well plates in RPMI-1640 containing 10% FBS. Different concentrations of imatinib and CPT are added and incubated for another 24 h. Then, 20 μL of MTT are added into each well and the absorbance at 570 nm is measured on an enzyme linked immunosorbent assay (ELISA) plate reader. The coefficient of drug interaction (CDI) between imatinib and CPT is determined according to a previous study. The calculated method is as follows: CDI/AB/(A × B). According to the absorbance of each group, AB is the ratio of the combination group to the control group; A or B is the ratio of the single agent group to the control group. CDI < 1 indicates a synergistic effect; CDI=1 indicates an additive effect; CDI > 1 indicates an antagonistic effect. In the combination treatment group, the concentrations of CPT are arbitrarily designated according to the 50% inhibitory concentration (IC50) value. Then, the cell viabilities are determined after treatment with different concentrations of imatinib plus CPT (constant CPT concentration for one cell type). Finally, the combination IC50 values of imatinib are calculated, and are represented in Table I. The primary CML cells CP1 to CP3 are isolated from patients in chronic phase, while BC1 and BC2 are isolated from patients in blast crisis. Three independent sets of experiments are performed. The IC50 values are presented as the mean±standard deviation (SD).
