Description
Technical Field
The invention belongs to the field of antitumor drugs, and in particular relates to a Salvianolic acid B and Rosavin combined antitumor pharmaceutical composition derived from natural plant sources.
Background
Salvianolic acid B the aromatic acid component of radix Salviae Miltiorrhizae has slightly bitter and astringent taste, and is effective in eliminating dampness. Is soluble in water, is one of the salvianolic acids which are studied more, and has important pharmacological actions on organs such as heart, brain, liver, kidney and the like. The product has effects of promoting blood circulation for removing blood stasis, dredging meridian passage, and can be used for treating ischemic apoplexy due to blood stasis blocking channels and collaterals, manifested by numbness of limbs, weakness, spasm pain, or movement disturbance, facial distortion, etc.
Rosavin is a natural component in the traditional Chinese medicine rhodiola rosea, and is mainly used for activating blood, stopping bleeding, clearing lung-heat, relieving cough, treating hemoptysis, cough due to pneumonia and leucorrhea of women. Anti-hypoxia, anti-fatigue and anti-cold; can improve the strength and flexibility of the organism and can quickly recover from fatigue; regulating immune system, and has bidirectional regulating effect on brain and organ function.
Modern pharmacological studies show that Salvianolic acid B has the effects of promoting blood circulation to remove blood stasis and treating blood vessels, while Rosavin has the effects of resisting oxidation, scavenging free radicals and improving the immune function of the organism.
In view of the success of the combined use of the anti-angiogenesis medicine and the tumor immunosuppression medicine in the clinical anti-tumor performance, the combination of two links of the traditional Chinese medicine is promoted to be excavated whether the synergistic anti-tumor effect can be achieved.
Disclosure of Invention
To better address the above considerations, the present invention combines Salvianolic acid B having anti-angiogenic effect and Rosavin having immunomodulatory effect, which are natural plant sources, in order to evaluate the combined anti-tumor effect of the compositions. Wherein Salvianolic acid B and Rosavin have the following specific structural formulas:

The anti-tumor beneficial effects are as follows: salvianolic acid B and Rosavin have wide sources, are easy to obtain, and have no obvious toxic or side effects on human bodies. According to the invention, the anti-tumor effect of the single drug Salvianolic acid B or Rosavin is obviously improved through the combination of Salvianolic acid B and Rosavin, the obvious inhibiting effect on the weight of a tested mouse is avoided, and the lung injury of the mouse caused by modeling can be improved, so that Salvianolic acid B and Rosavin are adopted to be combined to improve the anti-tumor curative effect, and the combined mode possibly plays a larger role in the future tumor treatment.
Specifically, in a mouse melanoma model, salvianolic acid B (80 mg/kg) and Rosavin (100 mg/kg) are combined, so that the tumor inhibition rate can be effectively increased, the tumor inhibition rate of subcutaneous transplantation tumor of a melanoma cell B16F10 mouse is 83.21%, the tumor inhibition rate is increased by 35.64% compared with 80mg/kg Salvianolic acid B alone, the tumor inhibition rate is increased by 10.97% compared with 100mg/kgRosavin alone, and the drug safety is good from the aspect of weight data.

Experimental data were analyzed using SPSS software (version 20.00), all data expressed in SD or SEM. Group difference analysis was performed using Prism 9.0 (Graph Pad Software Inc, san Diego, CA). The difference of P <0.05 is statistically significant.
1.5 Experimental procedure
1.5.1 Establishment of C57BL/6 subcutaneous melanoma animal model: B16F10 melanoma cells were resuspended in PBS to adjust cell concentration to 1 x 10 6 /mL. 200 mu L of cell suspension was inoculated to the right of C57BL/6 miceGroin measurement, and tumor volume reaching 50-100mm 3 At this time, model mice were randomly divided into 9 groups (n=10), and were dosed for about 2 weeks in the above-described experimental animal group and dose setting, and the body weight was weighed every 3 days during this period, and tumor volumes were measured and calculated (tumor volume=1/2×a×b 2 A is the major diameter of the tumor and b is the minor diameter of the tumor), and a tumor growth curve is plotted. About 2 weeks of treatment, mice were sacrificed, tumor tissues were dissected and organ tissues were photographed and weighed and saved as needed for subsequent experiments.
Based on the measured results, the relative tumor volume (relative tumor volume, RTV) is calculated as: rtv=vt/V0. Where V0 is the tumor volume measured at the time of divided cage administration (i.e., d 0), and Vt is the tumor volume at each measurement. The evaluation index of the anti-tumor activity is relative tumor proliferation rate T/C (%), and the calculation formula is as follows:
T RTV : treatment group RTV; c (C) RTV : negative control RTV
The tumor inhibition rate calculation formula is as follows:
T weight : average tumor weight in treatment group; c (C) weight : average tumor weight of the negative control group.
