Description
Technical field
The present invention relates to field of medicaments Chinese medicine carrier, particularly a kind of pulullan polysaccharide carrier material and preparation method thereof with cancer target effect.This carrier material is a biotinylation pulullan polysaccharide derivant.
Background technology
Pulullan polysaccharide (Pullulan) Chinese also is translated into pullulan, pullulan, general poly-polysaccharide or pulullan.It is the extracellular polysaccharide of the mould generation of falx of sprouting, and with α-1, it is main that the 6-glycosidic bond constitutes the homotype polysaccharide in conjunction with maltose, be glucose by α-1, the 4-glycosidic bond is combined into maltotriose, two ends are again with α-1, the 6-glycosidic bond is with other maltotriose combination, and macromolecule polysaccharide so repeatedly is formed by connecting.α-1,4-glycosidic bond same α-1, the ratio of 6-glycosidic bond is 2: 1, the degree of polymerization (D.P) is 100-5000.Commodity pulullan mean molecule quantity 2X10
5, approximately form by 480 maltotrioses.This material is nontoxic, no mutagenic action, and colorless and odorless, edible, have excellent biological compatibility, can be degraded by the body endo-amylase, be a kind of excellent drug carrier material.Its aqueous solution viscosity is starkly lower than other polysaccharide solution, makes it more help practical application.Research shows that also pulullan polysaccharide can combine with the galactosylated acceptor of surface of hepatocytes, can be the medicine liver target new material is provided.But, because the water solublity of pulullan polysaccharide is extremely strong, so want in aqueous solution, to prepare can medicine carrying microgranule, must in preparation process, add cross-linking agent, as glutaraldehyde etc., these deleterious cross-linking agent are difficult to thoroughly remove at last handling process, will cause final product to have certain toxicity.In recent years, synthetic hydrophobically modified pulullan polysaccharide derivant has been widely used in the delivery system of number of chemical medicine, protein drug and genomic medicine as pharmaceutical carrier.
Biotin (biotin) claims biotin again, molecular formula C
10H
16N
2O
3S, chemical structural formula:
Biotin is a kind of water soluble vitamins of needed by human, but human body can not self be synthetic, must replenish by extraneous.Studies show that further the nearly all cell surface of human body all has biotin receptor expression, especially tumor cell.Tumor cell increases fast needs a large amount of trophic factors, and the biological example element is so cell surface meeting overexpression can form one like this and more normally organize the higher relatively zone in conjunction with biotin in conjunction with the receptor of biotin around tumor cell.Utilize these characteristics can be with the target spot of biotin receptor, by making material have the tumor cell targeting in conjunction with biological rope as a kind of specific recognition.
As micromolecular biotin, the advantage that more traditional tumor targeted molecular antibody has is its Stability Analysis of Structures, and non-immunogenicity has strong specific bond ability with cell surface, enters cell by receptor-mediated endocytosis by cell membrane.
Summary of the invention
The present invention aims to provide a kind of pulullan polysaccharide carrier material with cancer target effect and preparation method thereof, and this carrier material is a kind of biotinylation pulullan polysaccharide derivant that can the target tumor cell.The present invention is the characteristics in conjunction with pulullan polysaccharide and biotin, by in conjunction with biotin, reduced the water solublity of pulullan polysaccharide, make it be easy in water solublity, form microgranule, the ability of their specific bond cell makes this derivant become a kind of carrier material with cancer target effect simultaneously.
Pulullan polysaccharide carrier material with cancer target effect provided by the invention is the pulullan polysaccharide derivant that biotin and pulullan polysaccharide reaction obtain, the biotin substitution value is 20-85%, it is in organic solvent, biotin, dicyclohexylcarbodiimide and 4-dimethylamino pyridine and pulullan polysaccharide reaction prepare through dialysis.Concrete preparation method is as follows:
1) biotin under the room temperature, dicyclohexylcarbodiimide (DCC) and 4-dimethylamino pyridine (DMAP) are dissolved in the organic solvent, react 1-3 hour;
2) under agitation pulullan polysaccharide is added in the above-mentioned reactant liquor, reacted 3-10 days;
3) with reacting liquid filtering, remove DCU, filtrate is put into bag filter, and dialysis is 3-10 days in 1-10L water dialysis solution, changes liquid every half an hour;
4) white depositions after will dialysing is filtered and is collected, and washs 3-5 time respectively with organic solvent and water, and drying obtains the white solid powder.
Described organic solvent is dimethyl sulfoxide (DMSO).
Described biotin: DCC: DMAP: pulullan polysaccharide=1: 0.1~10: 0.01~10: 0.0001~0.001 (mol ratio).
Total reactant concentration is 0.1~25% in the described organic reagent.
The required organic reagent of described washing is: dichloromethane.
The molecular weight of described pulullan polysaccharide is (20,000-200,000) (1.2 * 10
-4-1.2 * 10
-3).Bag filter molecular cut off 2,000-40,000; Dialysis solution is a deionized water.
Pulullan polysaccharide carrier material with cancer target effect provided by the invention is the characteristics in conjunction with pulullan polysaccharide and biotin, by in conjunction with biotin, reduced the water solublity of pulullan polysaccharide, make it be easy in water solublity, form microgranule, the ability of their specific bond cell makes this derivant become a kind of carrier material with cancer target effect simultaneously.The synthetic pulullan polysaccharide carrier material of the present invention is a biotinylation pulullan polysaccharide derivant, and preparation method is simple, favorable reproducibility.
