Description

With 3S-tetrahydrochysene-β-Ka Lin-3-carboxylic acid is hybridization peptide, its preparation method and the application of connecting arm
Technical field
The present invention relates to a kind of hybridization peptide, relating in particular to 3S-tetrahydrochysene-β-Ka Lin-3-carboxylic acid is hybridization peptide, its preparation method of connecting arm, and the application that the invention still further relates to this hybridization peptide conduct and use thrombolytic agent belongs to field of medicaments.
Background technology
Medicine ubiquity systemic bleedings such as streptokinase, urokinase and the rt-PA tendency and the immunogenic response of the treatment acute thrombus embolism class diseases of present clinical use, seeking safely and effectively, thrombolytic agent is one of focus of new drug research.The contriver is first guide structure with fibrin degradation product (FDP) P6A (ARPAK), carries out structural modification by liquid phase is synthetic, has obtained a series of oligopeptides (contriver: Peng Shiqi, Zhao Ming, Wang Chao, the pivot Tang Dynasty, Wang Yinye; Denomination of invention: cardiovascular active polypeptide and their the synthetic and application in medical science; Granted publication number: CN1055479C; Granted publication day: on August 16th, 2000).These oligopeptides have clear and definite thrombus dissolving activity, become outstanding thrombus dissolving oligopeptides elder generation guide structure.When the metabolism of research P6A and analogue, the contriver uses LC/MS tracking P6A and analogue in the intravital variation of mouse, finds that P6A is Arg-Pro-Ala-Lys-OH, Pro-Ala-Lys-OH, Ala-Arg-Pro-Ala-OH and four kinds of meta-bolitess of Ala-Arg-Pro-OH at the mouse vivo degradation.The contriver has prepared this four kinds of meta-bolitess with liquid phase synthesizing method, their application prospect (Peng Shiqi on the rat suppository model, have been confirmed as thrombolytic agent, Zhao Ming, Wang Chao, Xu Youxuan, Wu Yanfen, the meta-bolites of P6A and the application in medical science thereof, number of patent application 01136780.6, Intellectual Property Right Bureau of the RPC).
P6A and analogue all have the inherent room for improvement as the meta-bolites of thrombus dissolving oligopeptides elder generation's guide structure and P6A as thrombus dissolving oligopeptides elder generation guide structure, be the albumen of existence in the body and the difficulty that polypeptide causes for their detection, and technology and financial difficulties that the LC/MS detection causes all have much room for improvement.The contriver notices that carboline carboxylate has outstanding antiplatelet aggregative activity (Yao Xinsheng etc., China's pharmaceutical chemistry magazine, 1995,5,134), the indole ring parent nucleus of carboline carboxylate has outstanding uv-absorbing character and has the potential application prospect as edible natural product simultaneously.The contriver adopts chemical process to synthesize carboline carboxylate, and carboline carboxylate is incorporated into preparation plan peptide in P6A and the correlated series as pharmacophore.The plan peptide that makes has comprised the thrombolysis activity of PAK sequence peptide, has also comprised the platelet aggregation inhibitory activity of carboline carboxylate, and has ultraviolet detectability (contriver: Peng Shiqi, Zhao Ming, Wang Chao, Wu Yanfen; Denomination of invention: contain the carboline carboxylate of P6A correlated series, their the synthetic and application in medical science; Granted publication number: CN1373139; Granted publication day: on October 9th, 2002).
Platelet aggregation plays an important role in thrombosis.Normal thrombocyte is activated under the inducing of thrombogen, adenosine diphosphate (ADP) or collagen, discharges arachidonic acid (AA).AA generates endoperoxide (PGH2) through cyclooxygenase catalysis.PGH2 generates thromboxane A2 (TXA2) under the effect of isomerase, cause platelet aggregation and adhesion.Behind the platelet activation, glycoprotein iib/iiia (GP IIb/IIIa) acceptor on surface exposes, and occurred conformation changes, and combines with Fibrinogen, causes thrombosis.In research GPIIb/IIIa acceptor and the scleroproein bonded process, find that the RGD sequence that exists among the scleroproein is mediation it self and GP IIb/IIIa bonded pass key sequence (Samanen J., et al., J.Med.Chem., 1991,34,3114).The contriver adopts liquid phase method to synthesize RGDS, RGDV and RGDF, and confirm that they can suppress thrombosis (what contain the RGD tetrapeptide synthesizes and function Acta Pharmaceutica Sinica, 1997,32,271 for Zhao Ming, Peng Shiqi).The contriver once reported, contained the tetrapeptide of RGD, for example RGDS, can be thrombolytic agent, for example urokinase is transported to the thrombosis position, has clear and definite target (Ling Shichang, Zhao Ming, Peng Shiqi, the liposome that RGDS modifies is as the research of pharmaceutical carrier targeting thrombolysis, journal of Beijing Medical University, 1994,26,174).

With scalp acupuncture with physiological saline (3ml/kg), the normal saline solution of urokinase (dosage is 20000IU/kg), respectively that the embodiment of the invention is prepared Ia, Ib, Ic, Id, Ie, If, Ig, Ih, Ii, Ij, Ik, Il, Im, In, Io, IIa, IIb, IIc, IId, IIe, IIf, IIg, IIh, IIi, IIj, IIk, IIl, IIm, IIn, the stage casing of the normal saline solution of IIo (dosage is 10nmol/kg) by bypass tube (containing fixedly spiral of the thrombus of accurately weighing), thrust away from the fixing nearly vein place of spiral of thrombus, open bulldog clamp, make blood flow flow to vein from artery by bypass duct, this is a rat arteriovenous shut Thrombolysis Model, slowly the liquid in the syringe is injected in the blood, make physiological saline (blank group), urokinase (positive controls) or Ia-o or II a-o (treatment group) are by blood circulation, and the sequential action of pressing vein-heart-artery is to thrombus.Timing during from start injection, behind the 1h from bypass duct the fixing spiral of removal of thromboses, accurately weigh.Ask fixedly of poor quality before and after the spiral administration of thrombus in every rat bypass duct, and thrombus quality difference of each group of statistics (X ± SD), and do the t check.
5) thrombus quality difference is listed table 1 in as a result.
