Example Embodiment

[0034] In the present invention, the method for preparing the puffer fish liver oil preferably includes the following steps: mixing the puffer fish liver with water, decoction for 2 to 2.5 hours, and collecting the upper layer of puffer fish liver oil. In the present invention, the decocting time is preferably 2.2h.

[0035] In the present invention, the mixing mass ratio of the puffer fish liver and water is (3-5):1, more preferably 4:1. In the present invention, the decoction temperature is 120°C to 130°C, more preferably 125°C. After decocting, the oil yield is about 75%, and the oil is yellow. After collecting the upper layer of puffer fish liver oil, the present invention preferably adopts a mesh screen to remove the oil residue and refrigerates. In the present invention, the size of the mesh screen is preferably 40 mesh. In the present invention, the temperature of the refrigeration is preferably 4°C.

[0036] The present invention also provides a preparation method of the...

Example Embodiment

[0043] Example 1

[0044] Preparation of tetrodotoxin mother liquid: weigh 50 μg of tetrodotoxin with a purity of 99% and dissolve it in 1 mL of puffer fish liver oil to prepare a medicine mother liquid.

[0045] Put the puffer fish liver into the pot, add 25% water according to the weight of the liver, simmer for 2 hours on a direct fire at 120°C, the oil yield is about 75%, and the oil is dark yellow. After collection, it is removed with a 40-mesh sieve Put the oil residue in a refrigerator at 4°C for later use.

[0046] Prepare a medicinal solution containing 1μg / mL of tetrodotoxin. First prepare 98mL of basic carrier, weigh 85mL of puffer fish liver oil, then add 3mL of turmeric oil, 2mL of geraniol oil, 2mL of sweet almond oil, 2mL of wheat germ oil, 4mL of Brucea javanica oil, and use a heated magnetic stirrer to heat the basic carrier to 60 After temperature, add 2 mL of mother liquor containing tetrodotoxin, stir for 90 minutes at a constant temperature of 60°C at 100 rpm t...

Abstract

The invention relates to applications of tetrodotoxin in preparation of drugs used for inhibiting lung cancer cell migration and propagation, and belongs to the technical field of medicine science medicine development. The drugs capable of inhibiting lung cancer cell migration and propagation comprise 0.5 to 2<mu>g/ml of tetrodotoxin and a drug carrier, and are capable of reducing lung cancer cellmigration and propagation capacity effectively, and promoting cell apoptosis.

Description

technical field [0001] The invention relates to the technical field of research and development of medical drugs, in particular to the application of tetrodotoxin in the preparation of drugs for inhibiting lung cancer cell migration and proliferation. Background technique [0002] Currently in China, cancer has become the number one cause of death, and the morbidity and mortality are still rising, posing a huge threat to public health. In 2016, more than 2.8 million people died of cancer in China, an average of 7,500 people per day. About 570,000 patients died of lung cancer, and the survival rate of lung cancer patients was only 16.1%. Therefore, lung cancer is known as "the world's number one cancer killer" with its high lethality. Among them, the invasion and metastasis of lung cancer as a highly metastatic malignant tumor to distant tissues and organs is an important cause of death of cancer patients. Therefore, the ability to control invasion and metastasis has becom...
