Description
Technical field
The present invention relates to drug fields, and in particular to extract a kind of noval chemical compound 3 from centipede, 8- dihydroxy isoquinolin with
And application of the active material in anti-malarial activity, antibacterial activity and anti-tumor activity medicine.
Background technique
Malignant tumour is the primary killer of human health.Although traditional tumour treatment has certain curative effect, due to chemistry
The non-specific cytotoxicity of drug has biggish toxic side effect to patient, while being also easy to generate drug resistance, gives tumor patient
Bring great pain.Since proposing tumor vessel hyperplasia theory from Folkman in 1972, by inhibit tumor vessel hyperplasia come
The report for treating tumour emerges in multitude, and achieves immense success.Tumor Angiongesis is the morphology of growth and metastasis of tumours
Basis.Most malignant entity tumors such as oophoroma, liver cancer, cervical carcinoma and breast cancer etc. are all blood vessel dependent tumors.Newly
On the one hand angiogenic provides nutrition and oxygen, the important channel of another aspect or metastases for tumour growth.Therefore, inhibit
Tumor neogenetic blood vessels can effectively inhibit the generation, development and transfer of tumour.
Centipede is terrestrial arthropod, all totally 22 links.Head kermesinus or bronzing, slightly gloss, there is head plate
Covering, head plate subcircular, front end is slightly prominent, and gnathopodite a pair is posted in two sides, and front end two sides have feeler a pair of.The first backboard of trunk
Homochromy with head plate, remaining 20 backboard is brown-green or blackish green, has gloss, often has two from the 4th backboard to the 20th backboard
Longitudinal furrow lines；Abdomen is faint yellow or brown color, shrinkage；From the second section, every section two sides have step a pair of；Step yellow is reddish brown
Color occasionally has yellow-white, is in hooked, the last is to step shape of tail, therefore also known as uropodium, easy to fall off.Matter is crisp, and section has crack.Gas
Micro- raw meat, there is a special pungent foul smell, acrid flavour, micro- salty.Major function relieve the wind syndrome antispastic, function poison dissipating bind, removes obstruction in channels to relieve pain.It is frightened for children
Wind, spasm of twitching, middle air port is askew, hemiplegia, tetanus, rheumatoid arthritis stubborn, sore, scrofula, venomous snake bite.
Complicated component in centipede, the toxic component containing two kinds of similar bee venom, i.e. histamine sample substance and hemolytic protein；Still
Fatty oil, cholesterine, formic acid etc..δ-oxylysine was once isolated again；Amino acid has histidine, arginine, ornithine, relies
Propylhomoserin, glycine, alanine, valine, leucine, phenylalanine, serine, taurine, glutamic acid.Through Literature Consult, have
(the practical oncology of Primary Study [J] of the centipedes tissue extract anti-tumor activity such as Qu Aibing, Zhao Weicheng, Liang Liang is miscellaneous by researcher
Will, 2003,17 (1): 29-30) centipede tissue extract detected using mtt assay, find its to stomach cancer cell and liver cancer cells compared with
Strong cytotoxicity.There are also researchers (in Wang Shuo, Qin Wenhui Scolopndra subspinipes multidens (Newport) and Scolopendra subspinipes antitumor action research [J]
Pharmacology of traditional Chinese medical formulae magazine is tested by state, 2011,13:156-158) the even of the huge centipede of more spine and Scolopendpa Subspinipes Mutilans L. KOCH is detected using identical method
Effect of the slurries to Human hepatoma cell line Bel-7402, confirming two kinds of centipedes has stronger antitumor action.Liberation army the 4th
Five or eight hospitals are (when Han Li, Zhou Yongqin, Han Yu Scolopendra extract induce cervical cancer Hela cells apoptosis and its research [J] of mechanism
Precious traditional Chinese medical science traditional Chinese medicines, 2007,18 (9): 2109-2111) influence that centipede is proliferated cervical cancer Hela cells is observed in a similar fashion,
Prove that the ether of centipede, ethanol extract have significant anti tumor activity in vitro to Hela cell.Nanjing Normal University Jiangsu
Province molecular medicine biotechnology key lab is (in antibacterial activity [J] of the Scolopendra subspinipes water extract such as Ren Wenhua, Zhang Shuanquan
Medicinal material, 2007,01:10-14) it is extracted centipede water extract and determines it with certain antibacterial activity.But at present there has been no
Research has shown that there is which kind of substance is antitumor or antibacterial activity component be specifically in centipede, since the component of Scolopendra extract is multiple
It is miscellaneous, and may be also containing the toxic component similar to bee venom, therefore centipede is preparing answering in antitumor or antibacterials field
With being constantly subjected to limit.
It is mostly isoquinoline alkaloid in antineoplastic alkaloids, which is widely used, and structure has multiplicity
Property.Rexahn company (Lee Young Bok, Ahn Chang-Ho, Cho Won-Jea.Substituted 3- (hetero)
arylisquinolinamine derivatives for therapeutic applications.WO 2008063548
A2,2008.5.29) possess 5,6 or 7 substitution 3- aminoisoquinoline derivatives can produce antitumor action, can significantly press down
Make the growth of resistance to taxol (taxol) HCT-15 human colon cancer cell model of nude mice bearing tumor tumour.Chinese Patent Application No. is
201210098631.2, data of publication of application is that the patent application document on July 25th, 2012 discloses dihydroisoquinoliness chemical combination
Object and its as the application for preparing plants antimicrobial drug has synthesized a series of dihydroisoquinoliness compounds as planting in the invention
