568-72-9 Usage
Description
Different sources of media describe the Description of 568-72-9 differently. You can refer to the following data:
1. Tanshinone IIA mainly exists in the roots of Salvia miltiorrhiza Bge. Traditional
Chinese medicine Danshen, slightly cold and bitter, is often used for activating
blood circulation and eliminating stasis in Chinese medicine. It can also promote
blood circulation, open the energy channels, calm the heart, cool the blood, relieve
swelling, remove twinge in the heart and stomach, and remove carbuncle and erysipelas. It is classified as high grade in Shen Nong’s Herbal Classic. It has been used
as a traditional Chinese medicine in clinical practice for thousands of years. And it
is not only recorded in the leading medical works through the ages but also in CP
and USP.
2. Tanshinone IIA (TSA) is a major lipophilic component of extracts from the root of S. miltiorrhiza, used widely in Chinese herbal medicine. It has anti-inflammatory activity, inhibiting production of TNF-α, IL-1β, IL-6, NO, INFγ, and expression of iNOS, and IL-12. It blocks human aortic smooth muscle cell migration, inhibits MMP-9 activity, and interferes with PI3K/Akt and ERK1/2 signaling pathways. It is cytotoxic to various cancer cells including A549 lung cancer cells and leukemia cells.Reduction of TSA by NAD(P)H:quinone oxidoreductase (NQO1) generates an unstable intermediate resulting in reactive oxygenase species-mediated apoptotic cell death.

Biochem/physiol Actions
Phenanthrenequinone constituent of Chinese medicinal herb Danshen (Salvia miltiorrhiza). Anti-inflammatory. Antioxidant. Cytotoxic against a variety of cell lines, inlcuding human glioma cells.
Pharmacology
Long-term researches show that tanshinone exhibits a variety of pharmacological
effects, such as the protection of the cardiovascular system, anti-infective effects,
and antioxidant effects.
As for the domestic pharmacological study of tanshinone IIA, it was first started
in the Shanghai Institute of Chinese Medicine. Professor Ding Guangsheng discussed the cardiovascular effects of tanshinone IIA.?He found that intraperitoneal
injection of tanshinone IIA sodium sulfonate (200?mg/kg) significantly prolonged
the survival time of mice under hypoxia atmosphere, and an increase in cardiac
output was observed in a dog under anesthesia with a one-time intravenous injection
of 20? mg/kg .
In recent years, the mechanism of tanshinone IIA is increasingly brought to further research. Tanshinone IIA can increase the activity of superoxide dismutase
(SOD) and interfere with the pathological process of many diseases, especially in
cardiovascular diseases. It can attenuate the damages from the reactive oxygen species to vascular endothelial cells, lower the risk of atherosclerosis, and reduce the
formation of atheromatous plaque.
tumor cells and the expression of various genes connected with the proliferation,
differentiation, and apoptosis of tumor cells. It may also have something to do with
the inhibition of telomerase activity in tumor cells, changes in antigen expression on
tumor cell surface, etc.
Clinical Use
Tanshinone IIA is a diterpenoid quinone liposoluble ingredient of high content, and
its chemical structure is the most representative in Danshen. In addition to tanshinone
IIA sodium sulfonate, there are a variety of preparations of Salvia common ketone
used clinically, such as tanshinone tablets, tanshinone capsules, tanshinone injection, Danshen Shuxin capsule, compound Danshen soft capsules, and compound
Danshen particles.
Cytotoxicity

Check Digit Verification of cas no
The CAS Registry Mumber 568-72-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 568-72:
(5*5)+(4*6)+(3*8)+(2*7)+(1*2)=89
89 % 10 = 9
So 568-72-9 is a valid CAS Registry Number.

This unique protocol exhibited atom-/step-economy, low cost, high efficiency and robust functional-group tolerance, which will greatly facilitate to diversify the A-ring of the bioactive natural product.
Atomatic Annulation Strategy for the Synthesis of Angularly-Fused Diterpenoid Quinones. Total Synthesis of (+)-Neocryptotanshinone, (-)-Cryptotanshinone, Tanshinone IIA, and (+/-)-Royleanone
Danheiser, Rick L.,Casebier, David S.,Firooznia, Fariborz
, p. 8341 - 8350 (2007/10/02)
The application of a photochemical aromatic annulation strategy in highly efficient total syntheses of several diterpenoid quinones isolated from the traditional Chinese medicine Dan Chen is reported.The pivotal step in each synthesis involves the assembly of the key tricyclic intermediate via the application of a recently developed "second generation" photochemical aromatic annulation method for the construction of highly substituted aromatic systems.In the total synthesis of neocryptotanchinone, the synthesis of the requisite diazo ketone anulation substrate 7 was achieved using paladium-mediated coupling reactions and an intramolecular Friedel-Crafts cyclization to form key carbon-carbon bonds.The pivotal aromatic annulation reaction was then accomplished by irradiating a solution of the diazo ketone 7 and the readily availabe siloxyalkyne 6 in benzene at room temperature.The desired tricyclic phenol 16 was produced in 58-65percent yield and was then converted to (+)-neocryptotanshinone (1) by treatment with tetra-n-butylammonium fluoride in the presence of oxygen.Cyclization to generate (-)-cryptotanshinone (2) was accomplished in high yield by brief exposure of 1 to an ethanolic solution of concentrated sulfuric acid, and dehydrogenation of 2 with DDQ furnished tanshinone IIA (3).As a further demonstration of the utility of the photochemical aromatic annulation strategy in the construction of angularly-fused diterpenes, the total synthesis of (+/-)-royleanone (4) was also investigated.Irradiation of a solution of the diazo ketone 18 and siloxyalkyne 25 produced the tricyclic intermediate 26, which was converted in two steps to royleanone by desilylation and oxidation.
