Description
Technical field
The present invention relates to the combination medicine of a kind of floral leaf containing industrial hemp extract and artemisine compounds, the joints
With the therapeutic agent that drug is for the cancer of the esophagus.Belong to pharmaceutical technology field.
Background technique
Tumour is a kind of uncontrolled cell proliferation class disease, and reason is complicated, is involved in multiple genetic, epigenetic, cell
And the exception in tissue level.Height variability on genome and apparent gene group level, it is multiple from transcript to albumen etc.
The extreme of biological level is heterogeneous and to the extremely strong adaptability of environment, is the root for the difficult severe that tumour becomes diagnosis and treatment art the most weary
This reason.
The cancer of the esophagus is common tumor in digestive tract, and there are about 300,000 people to die of the cancer of the esophagus every year in the whole world.Its disease incidence and dead
The various countries Wang Shuai are widely different.China is one of Esophageal Cancer area in the world, and every annual is died of illness about 150,000 people.Male is more than
Female, age of onset is mostly at 40 years old or more.The Crowds Distribute of the cancer of the esophagus and age, gender, occupation, race, region, living environment,
Dietary life habits, genetic predisposition etc. have certain relationship.Cancer of the esophagus early symptom is often unobvious, but when swallowing thick and stiff food
May have it is different degrees of it is uncomfortable feel, weight when symptom is light is made slow progress.The typical symptom of middle and advanced stage is swallowed tired for progressive
Difficulty, the food of difficult dry throat before this, after but semiliquid diet, last water and saliva can not swallow.Mucoid phlegm often is spat, under
The saliva of pharynx and the secretion of oesophagus.Patient is gradually thin, is dehydrated, is powerless.Continue pectoralgia or backache is expressed as advanced stage symptom, cancer
It has invaded outside oesophagus and has organized.Operation excision is to treat the prefered method of the cancer of the esophagus, when knurl is less big and with major organs it is close
It cannot then be cut off when being adhered；Chemotherapy, radiotherapy will inspect periodically patient's blood picture and hepatic and renal function, and pay attention to drug response.Thus grind
Sending is effective, the lower anti-tumor drug of toxic side effect is significant and the urgent need of clinical treatment.
Industrial hemp floral leaf extract is extracted from cannabis plant flower, leaf and is obtained, containing there are two types of main components: tetrahydro hemp
Phenol (THC) and cannabidiol (CBD).THC (tetrahydrocannabinol) psychotropic activity is high, and it is that drugs are big that Central nervous effect is extremely strong
The major toxicity ingredient of fiber crops;And CBD can hinder influence of the THC to nerve system of human body, not have psychotropic activity and additive, peace
Full tolerance is good.In addition, CBD also shows the pharmacological activity such as anti-spasm, antianxiety, anti-inflammatory, anticancer, antidepression, in epilepsy, suppression
Huge application potential and industrial hemp are shown in the treatment of a variety of diseases such as strongly fragrant, parkinsonism, cancer becomes one kind
Important bio-pharmaceuticals raw material.
Qinghaosu extracts isolated one kind from compositae plant artemisia annua (Atemisia annua L.) leaf and contained
The Sesquiterpene lactones compound of oxygen bridge structure is the active drug for the world control malaria prevalence that WHO assert.Due to qinghaosu
In the presence of water-soluble and fat-soluble difference, difficulty is made suitable preparation and causes the problems such as bioavilability is low and re-ignition is high, in qinghaosu
On the basis of derive several common drugs again through chemical improvement, such as dihydroartemisinine, Artemether, arteether, Artesunate.This
A little artemisinin derivatives not only have efficient antimalarial, and low toxicity works the advantages that rapid, also in antitumor, immunosupress such as erythema
Lupus, anti parasitic are anti-inflammatory etc. to achieve compared with good therapeutic effect.Artemisine compounds mainly pass through inhibition freely
The generation of base plays the effect of anti esophageal cancer.
Industrial hemp floral leaf extract is united and applied in the cancer of the esophagus with artemisine compounds and explored by the present invention, with
Industrial hemp floral leaf extract and qinghaosu chlorins compound are widened in the clinical value of medicinal aspect.Inventor passes through pharmacodynamics
The study found that industrial hemp floral leaf extract joint artemisine compounds can effectively inhibit tumour growth, the especially cancer of the esophagus.
It can be seen that industrial hemp floral leaf extract and artemisinin derivatives, which are used in combination, is preparing anti esophageal cancer field with fine
Application prospect.
