Biological Activity

Cryptotanshinone was originally isolated from the dried roots of Salvia militorrhiza, an herb that is used extensively in Asian medicine and that is known to exert beneficial effects on the circulatory system.Cryptotanshinone rapidly inhibited STAT3 Tyr705 phosphorylation in DU145 prostate cancer cells and the growth of the cells through 96 hours of the treatment.Cryptotanshinone significantly attenuated atherosclerotic plaque formation and enhanced plaque stability in ApoE-/- mice by inhibiting lectin-like oxLDL receptor-1 (LOX-1) and matrix metalloproteinase-9 (MMP-9) expression, as well as inhibiting reactive oxygen species (ROS) generation and nuclear factor- kappa B (NF-κB) activation.In vitro,Cryptotanshinone decreased oxLDL-induced LOX-1 mRNA and protein expression, and thereby, inhibited LOX-1-mediated monocytes adhesion to HUVECs through reducing the expression of adhesion molecules (ICAM-1 and VCAM-1).Cryptotanshinone inhibited NADPH oxidase subunit 4 (NOX4)-mediated ROS generation and consequent activation of NF-κB in HUVECs.

Cell Experiment
Cell lines KATO III, DU145, PC3, LNCaP, MDA-MB-231, MDA-MB-468, MDA-MB-453, MCF-7, MCF-10A, HeLa and HCT-116
Preparation method Exposing cells to Cryptotanshinone for 24 or 48 hours. For the determination of cell proliferation, adding the cell proliferation reagent WST-1 and using an ELISA reader to measure WST-1 formazan quantitatively at 450 nm.
Concentrations Dissolved in DMSO, final concentrations ~50 μM
Incubation time 24 or 48 hours
Animal Experiment
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
Dosages ~600 mg/kg/day
Administration Orally
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
