Concrete, the optional organic polymer polymerization carrying cation group of the carrier material of described band cation group Thing, the polysaccharide of band cation group, the polypeptide of band cation group, the albumen of band cation group and cation lipid The combination of one or more in body etc..
Described organic high molecular polymer refers specifically to construction unit (a kind of construction unit or the various structures identical by many Unit) high-molecular weight compounds that is formed by connecting is repeated by covalent bond, in an embodiment of the present invention, the most available Organic high molecular polymer with cation group includes but not limited to: polymine, tree-like daiamid macromolecule, sun from In sub-polyester (object lesson such as cation poly phosphate, poly-phosphoramide, polymethacrylates etc.), polyvinylpyridine etc. The combination of one or more.
Described polysaccharide refers specifically to generate multiple monosaccharide, more specifically more than ten monosaccharide during a part hydrolysis Sugar, the polysaccharide of described band cation group can be the polysaccharide of band cation group own, it is also possible to be to be obtained by modification The polysaccharide with cation group obtained.Polysaccharide is modified so that it is this area with the technology of cation group Prior art, can be specifically the method such as grafted amino group on side chain.In an embodiment of the present invention, the most available Polysaccharide with cation group includes but not limited to: Chitosan-phospholipid complex (object lesson such as chitosan quaternary ammonium salt, low takes For degree carboxymethyl chitosan, N-trimethyl chitosan TMC, containing imidazole radicals chitosan, Chitosan-Thiolated Polymers etc.), cationic starch and derivative One in thing (object lesson such as the cyclodextrin etc. with cation group) and other polysaccharides with cation group Or multiple combination.
The polypeptide of described band cation group or albumen can be the polypeptide per se with cation group or albumen, it is possible to To be the polypeptide with cation group or albumen obtained by modification.In an embodiment of the present invention, specifically can be selected for The polypeptide of band cation group or albumen include but not limited to: polylysine or poly arginine and their derivant are (concrete The example of derivant is such as: introduce PEG, galactose, lactose, folic acid, transferrins etc. on polypeptide), collagen, gelatin, serum white The combination of one or more in albumen etc..Due to some albumen (such as collagen, gelatin, serum albumin etc.) at various ph values Both it had been possibly shown as positively charged, it is also possible to be shown as electronegative (with positive charge under the pH value less than isoelectric point, IP, at height With negative charge under the pH value of isoelectric point, IP), so this type of material can not only be used for cationic layer, it is possible to as anion layer.
Described cationic-liposome can be selected for the various cationic-liposome in this area, concrete available example include but not It is limited to: with the cationic-liposome that DOTMA is similar to body, prepared by DOTAP, spennidine cholesterol.
In medicine carrying tissue adhesive film provided by the present invention, the carrier material of described band anionic group be per se with Negative charge or be dissolved in after solvent ionizes the material with negative charge, can be dissolved in water in an embodiment of the present invention After ionizing, with the material of negative charge.
The carrier material of described band anionic group preferably can the biocompatible materials of vivo degradation.
Concrete, the optional organic polymer polymerization carrying anionic group of the carrier material of described band anionic group Thing, the polysaccharide of band anionic group, the polypeptide of band anionic group, the albumen of band anionic group and anion lipid The combination of one or more in body etc..
In an embodiment of the present invention, the organic high molecular polymer of concrete available band anionic group include but It is not limited to: such as the anion being made up of dicarboxylic acids be given in CN1524184A.
The polysaccharide of described band anionic group can be the polysaccharide of band anionic group own, it is also possible to be by changing Property obtain the polysaccharide with anionic group.Polysaccharide is modified so that its with anionic group technology for this The prior art in field, is specially such as (more specifically example such as carboxymethyl starches etc.) such as anionic starch.Real in the present invention one Executing in mode, the polysaccharide of concrete available band anionic group includes but not limited to: carboxymethyl cellulose, carboxymethyl chitosan Sugar, hyaluronic acid, alginic acid, carboxymethyl starch, chondroitin sulfate, heparin and their derivant and other with the moon from The combination of one or more in the polysaccharide of subbase group etc..
