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
[0039] [Example 1]: N-(1,6,6-trimethyl-10,11-dioxo-6,7,8,9,10,11-hexahydrophenanthrene[1,2-b] Preparation of furan-2-ylsulfonyl)acetamide sodium salt
[0040] Step 1: Preparation of Intermediate-1 Tanshinone IIA Sulfonyl Chloride
[0041] Tanshinone IIA (10 g, 33 mmol) was added dropwise into 150 mL of sulfuryl chloride, and refluxed for 1 hour. The temperature of the reaction system was lowered to room temperature, and the unconsumed sulfuryl chloride 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] Step 2: Preparation of Tanshinone IIA Sulfonamide
[0043] The product obtained in Step 1 (1 g, 2.55 mmol) was dissolved in 10 mL of THF, and added dropwise to vigorously stirred 0-degree ammonia water (10 mL). After the dropwise addition was complete, stir at room...

Embodiment 1
[0049] According to the preparation method of Example [1], replace acetyl chloride with propionyl chloride to obtain N-(1,6,6-trimethyl-10,11-dioxo-6,7,8,9,10,11 - Hexahydrophenanthrene[1,2-b]furan-2-ylsulfonyl)propionamide sodium salt. 1 H NMR (400MHz, D 2 O) δ7.90-7.86(m, 2H), 3.20(m, 2H), 2.52(s, 3H), 2.01(m, 2H), 1.60(m, 2H), 1.53(m, 2H), 1.29( s, 6H), 1.11(t, 3H), LCMS m / z, 428.1(M-1) +

Abstract
The invention relates to tanshinone IIA derivatives. The structure of the tanshinone IIA derivatives are carbonylated and acylated products of tanshinone IIA furan ring 2-position sulfonamide as show in a formula (I), wherein R is C1-6 alkyl, cycloalkyl, alkenyl, alkynyl, aryl and aromatic heterocycle and M is a metal ion such as a sodium salt. According to the compounds, on the basis that the activity and water solubility of sodium tanshinone IIA sulfonate are maintained, the acidity of the compounds is reduced; when sodium tanshinone IIA sulfonate is injected, the stimulation to patients is reduced and the stability of the compounds is improved.
