Cissus assamica (Laws.) Craib [Cissus assamica (Laws.) Craib] is Vitaceae (Vitaceae) Cissus (Cissus L.) plant, among the peoplely is used for the treatment of traumatic injury, sprains, rheumatic arthritis pain, fracture and carbuncle pyogenic infections from tumour or sore.Guangxi one band is used for the treatment of venom and has good effect.The extraction and the The Chemical Constituents of relevant this plant effective site are not appeared in the newspapers so far as yet.
Endothelin is a kind of bioactive substance of latest report in the world.The generation development and the Endothelin of many cardiovascular and cerebrovascular diseases have confidential relation, and as hypertension, coronary heart disease, cerebrovascular accident, heart failure etc., Endothelin participates in pathology, the physiological process of these diseases.Many countries are the pathological index of Endothelin as diseases such as hypertension, coronary heart disease, cerebrovascular accident, heart failure, and treat above-mentioned disease by the biological agent of regulating Endothelin.Therefore, screening is a kind of can the bioactive medicine of antagonism Endothelin be present extremely important and significant thing.
Stilbenes compound is that the structural formula parent nucleus is a compounds of stilbene.Its structural formula is a following general formula I:
Wherein 3,4,5,2 ', 3 ', 4 ', 5 ', 6 ' diverse location, the not isoplastic replacement on two phenyl ring constituted numerous stilbenes compounds.This compounds can be known as medicine, and still, up to the present, relevant this compounds of Shang Weijian is used to prepare the report that endothelin antagonist is used.
One of the object of the invention provides a kind of pharmaceutical preparation, and it contains the effective component extracts of Chinese herbal medicine Cissus assamica (Laws.) Craib.
Another object of the present invention provides Chinese herbal medicine Cissus assamica (Laws.) Craib extraction of effective components.
Another object of the present invention provides stilbenes compound and the application of derivant in the preparation endothelin antagonist thereof.
Furtherly, another object of the present invention provides 3, and 4 ', the application of 5-trihydroxy trans-stilben in the preparation endothelin antagonist.
We had once carried out the pharmacological research of antagonism Endothelin (ET) to the Cissus assamica (Laws.) Craib plant; find the contraction of the isolated aorta bar that its can antagonism be caused by ET; and to due to whole animal death have protective effect; and then it the extraction and the mask work of chemical constituent have been carried out; in the hope of the effective ingredient of discovery antagonism ET, thereby finished the present invention.
Pharmaceutical preparation of the present invention contains the effective extract part of Cissus assamica (Laws.) Craib plant for the treatment of effective dose.
Medicine of the present invention preferably contains effective extract part of the Cissus assamica (Laws.) Craib plant of 0.1-99.9% weight portion.

As can be seen from the above table, the pressor effect that heavy dose of CA-1201 (10mg/kg) causes ET-1 has tangible antagonism, compare this antagonism with matched group tangible dose dependent is arranged, but low dose of CA-1201 (5mg/kg) has the trend of the boosting of passivation ET-1, but does not have the significance meaning.Experimental example 4 CA-1201 are to the arrhythogenic antagonism of ET-1
The SD rat, body weight 250 ± 50g, after fasting was supplied water 18 hours, after 846 animal compound anesthetic intramuscular injection, back of the body position was fixing, and II leads the variation of recording ecg with the standard limbs.After treating that electrocardiogram is stable, intravenous injection ET-10.6nmol/kg, the electrocardiogram of record after the administration gives the CA-1201 of various dose group ( intravenous injection 10,30,90 and intramuscular injection 10 μ g/kg) then, observes and respectively organize Electrocardiographic variation in whole experiment (60 minutes).
CA-1201 has tangible antagonism to various types of arrhythmia that endothelin-1 causes, effect to ventricular arrhythmia is comparatively obvious, after the intramuscular injection, the also arrhythmia that causes of antagonism ET-1 effectively is better than intravenous injection to the antagonism trend of chamber property and atrial arrhythmia.
Accompanying drawing 1 is to be used to illustrate that the CA-1201 intravenous injection is to the influence of ET-1 boosting (n=5, x ± SD).
