Cryptotanshinone - Reference Information
| plant source: | salvia miltiorrhiza |
| Overview | Cryptotanshinone (cryptotanshinone,CTS) is the main fat-soluble extract of Salvia miltiorrhiza. It is an orange needle-like crystal. It belongs to diterpene quinone compounds. Most of these components have a ternary or quaternary ring o-quinone or p-quinone structure on the skeleton, making most of them have anti-tumor, antioxidant, anti-inflammatory, antibacterial and other activities. In recent years, great progress has been made in the study of the pharmacological activity mechanism of this compound. |
| effect | 1) therapeutic effect on hepatobiliary cancer the anti-cancer target of cryptotanshinone is predicted by screening technology based on reverse efficacy. The results showed that cryptotanshinone could inhibit the proliferation of human liver cancer SMMC-7721 cells in cell experiments, which may be closely related to its reduction of MAP2K1 protein mRNA expression. In the experiment of human liver cancer HepG-2 cells, Xie Fei found that cryptotanshinone can inhibit Bcl-2 expression, promote Bax expression, regulate Bel-2/Bax ratio, and finally activate downstream effector easpase-3, thus inducing HepG-2 apoptosis. 2) Therapeutic effect on prostate cancer Prostate cancer (PCa) is a common clinical cancer, and androgen receptor (AR) is the main goal of treating PCa. Reducing androgen substances or preventing AR production is widely used to inhibit AR-mediated PCa cell growth. In vivo and in vitro experiments in mice, tanshinone (including cryptotanshinone, tanshinone I, and tanshinone IIA) can inhibit 130PCa cells, and its mechanism may be by blocking the cell cycle and inducing apoptosis, thereby inhibiting its growth. In addition, cryptotanshinone can inhibit PCa by inhibiting lysine-specific demethylase 1(LSD1), regulating the demethylation function of histone H3 lysine 9(H3K9), down-regulating AR signal and inhibiting its transcriptional activity. It not only affects AR function, but also significantly inhibits AR transcription activity and AR target gene expression at mRNA and protein levels. At the same time, it also blocks the interaction between AR and lysine specific demethylase 1LSD1), inhibits AR target gene promoter, and increases monomethylation and dimethylation of histone H3 lysine 9(H3K9). |
| Salvia miltiorrhiza active ingredient | Cryptotanshinone (cryptotanshinone) is a diterpene quinone extracted from the dried root and rhizome of Salvia miltiorrhiza, a plant in the family Lamiaceae.

HPLC method Determination of baicalin, cryptotanshinone and tanshinone ⅡA in Danqin dropping pills by HPLC. Preparation of 1.1 reference substance solution: 24, 10 and 12mg of baicalin, cryptotanshinone and tanshinone ⅡA reference substance are accurately weighed respectively, placed in a 100mL brown volumetric flask, dissolved with ethanol and diluted to scale, and shaken well. Accurately measure 5mL, place it in a 10mL brown volumetric flask, add ethanol to dilute to scale, shake well, and obtain a mixed reference solution containing 120 μg/mL of baicalin, 50 μg/mL of cryptotanshinone and 60 μg/mL of tanshinone Ⅱ A60μg/mL respectively. 1.2 Preparation of the test solution: Take 20 Danqin dripping pills, grind them evenly, weigh 125mg precisely, place them in a 50mL conical flask, add 25mL ethanol precisely, weigh them, dissolve them by ultrasound for 5min, dry the wall of the flask, make up the lost ethanol, shake well, and obtain the product. 1.3 chromatographic conditions and system applicability tests: MZC18 analytical column (250mm × 4.6mm,5 μm),C18 protective column (Beijing Analytical Instrument Factory, 5.0mm × 4.6mm,5 μm); Mobile phase A is 85% acetonitrile aqueous solution (containing 0.5% triethylamine, phosphoric acid adjusted pH3.0), mobile phase B is 10% acetonitrile aqueous solution (containing 0.5% triethylamine, phosphoric acid adjusted pH3.0), gradient elution, the program is 0 ~ 100%,B 80% ~ 0%; Volume flow rate: 1.0 mL/min; Detection wavelength: 270nm. Under this chromatographic condition, baicalin, cryptotanshinone, tanshinone ⅡA reference substance, negative samples (the mass ratio of PEG6000, PEG1000, and propylene glycol is heated and melted at 7: 63: 10) and Danqin Dropping Pills were measured. Figure 1. It can be seen that the retention times of baicalin, cryptotanshinone and tanshinone ⅡA are 6.7, 19.3 and 22.8min respectively, and the separation degree from their adjacent peaks is greater than 1.5. The theoretical plate number analysis is 3600, 7500 and 6300. 2. electrochemical method because cryptotanshinone molecule contains quinone structure and is easy to be redox, it can be detected by electroanalytical chemistry method. The electrochemical behavior of cryptotanshinone on the electrode was studied by cyclic voltammetry and a new method for the determination of cryptotanshinone by differential pulse voltammetry was established. In pH 4.0 acetate buffer, the oxidation peak current has a good linear relationship with the concentration of cryptotanshinone in the range of 3.0 × 10-8~2.0 × 10-7mol/L, and the detection limit is 2.0 × 10-9mol/L. Glassy carbon electrode can effectively eliminate the interference of other components in the sample to the determination of cryptotanshinone, and has been used for the direct determination of cryptotanshinone in actual samples. The method has high sensitivity and wide detection range. |
| preparation research | cryptotanshinone is insoluble in water, has low dissolution in vitro and low oral bioavailability. In order to improve the dissolution of cryptotanshinone, various preparations were studied. 1. Liposomes Cryptotanshinone nanoliposomes were prepared by ultrasonic-homogenate-freeze-drying method. Liposome as a new drug carrier has good effects in improving the dissolution rate of drugs, enhancing the targeting, slow release, controllability, low degree and intelligence of drugs. In addition, it can also activate the body's own immune function, reduce the therapeutic effect of drugs, and improve the patient's compliance. Cryptotanshinone nanoliposomes were prepared by freeze-drying method with a particle size of 20-80nm. With the decrease of the ratio of soybean lecithin to cryptotanshinone, the particle size gradually decreases and the encapsulation efficiency gradually decreases. In vitro drug release showed zero-order kinetic drug release characteristics. The best process conditions for preparation, the weight ratio of drug/carrier is 1:20, and the volume ratio of water/oil is 3:2. 2. Solid dispersion The solid dispersion of cryptotanshinone-PVP was prepared by solvent evaporation method, and the solid dispersion of cryptotanshinone-PEG was prepared by melting method. The properties of solid dispersion and its effect on dissolution were studied by in vitro dissolution, differential thermal analysis and microscopic observation. Results On the surface, the dissolution rates of PVP and PEG solid dispersions reached 9.7 times and 7.5 times of that of bulk drugs respectively in 45min. The characteristic melting peak of cryptotanshinone disappeared in DTA curve of solid dispersion. Both solid dispersions can significantly improve the dissolution of cryptotanshinone, while PVP solid dispersion has higher dissolution than PEG solid dispersion. |
| metabolism in vivo | within 3 hours after oral administration of cryptotanshinone in rats, the first metabolites in bile include tanshinone II-A in addition to the original drug, indicating that dehydrogenase in the intestine or liver may convert cryptotanshinone into tanshinone II-A. 1,2,3,4 and 5 metabolites with greater polarity than cryptotanshinone appeared in bile after 6 hours of oral administration of the drug in rats, indicating that the drug has undergone repeated hepatic and intestinal circulation and is catalyzed by liver microsomal drug enzymes., Gradually converted into corresponding metabolites. For example, hydroxytanshinone II-A may be catalyzed by hydroxylase, and the condensate of tanshinone II-A and glutamate may be converted by acyl-CoA and glutamate 2-N acyltransferase. Metabolites 2,3,5 and 6 were positive in vitro antibacterial tests, but the original drug (No. 6) was still the most active, so the original drug may still be the main pharmacological effect in animals. Figure 2 shows the possible pathways for the biotransformation of cryptotanshinone in animals. |
| use | used for content determination/identification/pharmacological experiments, etc. Pharmacological effects: It has anti-oxidation and anti-aging functions, and has a certain effect on the treatment of coronary heart disease, angina pectoris, and myocardial damage. Cryptotanshinone has antibacterial effect, 1 mg/ml has inhibitory effect on Staphylococcus aureus and Pseudomonas aeruginosa, and also has certain inhibitory effect on hemolytic streptococcus. a diterpenoid compound, is an effective STAT3 inhibitor. |
