However, due to the strong acidity of the sulfonic acid group, the pH of the injection is low, and the product is very irritating, which brings pain to the patient.
And because of its poor stability, it is easy to remove sulfonate groups during the drug placement process to form tanshinone IIA, which is precipitated in the injection

Embodiment 1
[0035] Example 1: (2-((1,6,6-trimethyl-10,11-dioxo-6,7,8,9,10,11-hexahydrophenanthrene[1,2-b] Preparation of furan)-2-sulfonamido)ethyl)phosphoric acid (DP-1)
[0038] Tanshinone IIA (10 g, 33 mmol) was added dropwise into 150 mL of sulfurylchloride, and refluxed for 1 hour. The temperature of the reaction system was lowered to room temperature, and the unconsumed sulfurylchloride was distilled off under reduced pressure. The remaining black oily liquid was dried under reduced pressure with an oil pump for 2 hours under the condition of avoiding light, and the obtained black oily liquid was directly used in the next reaction.

[0042] Example 2: (2-((1,6,6-trimethyl-10,11-dioxo-6,7,8,9,10,11-hexahydrophenanthrene[1,2-b] Preparation of furan)-2-sulfonamido)ethyl)trisodium phosphate (DP-1-S)
[0043]
[0044] DP-1 (100 mg, 0.20 mmol) was placed in 5 mL of methanol, sodiumbicarbonate (50 mg) was added thereto, stirred at room temperature for 30 minutes, filtered, and the filtrate was evaporated to dryness to obtain DP-1-S, 110 mg, with a quantitative yield.

[0048]
[0049] step 1 : Formyltanshinone IIA( intermediate IN-B) preparation of
[0050] Tanshinone IIA (30 g, 0.01 mol) was dissolved in 300 mL of DMF, 30 mL of phosphorus oxychloride was added dropwise at room temperature, and stirred at room temperature for 2 hours. After the reaction was completed, the reaction solution was poured into 1000 mL of ice-water mixture, stirred slowly, and a light yellow solid was precipitated, filtered with suction, and the filter cake was washed with cold water three times, 100 mL each time. The filter cake was collected and vacuum-dried to obtain 32 g of tanshinone IIA-2-carbaldehyde (light yellow solid), and the yield was quantitative.

Abstract
The invention discloses a tanshinone IIAphosphoric acid derivative and synthesis and use thereof as a medicine for treatment. In particular, the present invention provides a novel derivative shown as a general formula (I) and a pharmaceutically acceptable salt thereof or a pharmaceutical composition containing the novel derivative shown as the general formula (I), and a method for preparing the novel derivative shown as the general formula (I). The invention also discloses use of the novel derivative, the pharmaceutically acceptable salt thereof or the pharmaceutical composition containing the novel derivative in preparation of medicines for treatment of coronary heart disease, angina, myocardial infarction, viral myocarditis, arrhythmia, cerebrovascular disease, hepatitis, pulmonary heart disease, bronchial asthma, cancer, kidneydisease, eye disease, thromboangiitis obliterans, hypertension, fractures, burns, surgical operations or behcet ' s syndrome. On the basis of ensurance of the activity of tanshinone IIA, the novel derivative, the water solubility of the pharmaceutically acceptable salt thereof or the pharmaceutical composition containing the novel derivative can be improved. Compared with tanshinone IIAsodiumsulfonate, the stability is improved, and because the acidity of the pharmaceutically acceptable salt thereof or the pharmaceutical composition containing the novel derivative is reduced obviously, injection stimulation can be avoided. All substituents of the general formula (I) are as defined in the specification.
