Description

Hydrophobic sol, Preparation Method And The Use containing albumen or polypeptide
Technical field
The invention belongs to materia medica and pharmaceutical art, be related to the hydrophobic sol containing albumen or polypeptide, its preparation method and Purposes.
Background technology
Some have protein and peptide such as trypsase, chymotrypsin, insulin, the parathyroid hormone of important application Deng, all it is hydrophilic, its hydrophobization has many important applications, for example:The stability of hydrophilic substance can be improved, can The fat-soluble of protein and peptide drugs is improved, increases the ability that medicine passes through membranes barriers;Albumen or peptide drug can be extended The action time of thing molecule, realize slow controlled release drug administration;Hydrophobization is carried out to protease to fix, can be greatly enhanced yield, and Be conducive to the separation of product and the recovery of protease.
Zhang Haizhou et al. passes through oily bag alcohol system, has prepared ascorbic non-aqueous solution, can greatly improve vitamin The stability of C.But oily bag alcohol system is unstable, therefore, Zhang Haizhou et al. is with cetyl polyethylene/polypropylene glycol -1,0/1 two Methylsiloxane(ABIL EM90, viscosity 400-2000cS)Make emulsifying agent, prepare cream preparation, oleyl alcohol can be avoided to separate (Zhang Haizhou, etc., for the research of ascorbic oily polyol system in stable cosmetic, 2009《Daily chemical industry》39 (4):249-252;Patent CN200810100726.7).United States Patent (USP) US2011/0147259A1 is dystectic auxiliary by adding Material trihydroxy stearic acid(110~140C of fusing point)With 12- hydroxy stearic acids(Fusing point 80C)To increase system viscosity(K value is situated between In 2,000cp-3,000,000cp), and then increase the stability of oily bag alcohol.Above-mentioned technical proposal, is by increasing viscosity It is layered with the auxiliary material for overcoming different densities, the stability of the oily bag alcohol formulations of raising, cream preparation or 2,000cp-3,000, The oily bag alcohol system of 000cp, those skilled in the art know, and these systems are not the molten of clear homogeneous truly Liquid, emulsifying agent ABIL EM90 used are only limitted to be applied in cosmetics by the description of product, can not be medicinal, and 12- hydroxyls Base stearic acid is classified as indirect food additive by U.S. FDA(For food containers and packaging material), can not be directly as medicine Thing auxiliary material is used.In addition, containing substantial amounts of polyalcohol in CN200810100726.7(40-80wt%,), it is difficult to it is significant to improve It is ascorbic fat-soluble.
Patent CN98126744.0 and CN200910027809.2 are by way of gene mutation, protease to be carried out Transformation, produces the protease variant that can be stable in the presence of in non-aqueous media.M.Hashimoto is by palmitic acid covalently tying The mode of conjunction is connected on insulin molecule, is found by the insulin after modification, and fat-soluble and cross-film ability is dramatically increased(M. Hashimoto,etal.(1992)J.Pharm.Pharmacol.44:555-559).But, the general character of these technological means is Industrialization high cost, and with the change of medicines structure, this is possible to change toxicity, the pharmacology of drug molecule.Comparatively, By the means of preparation, increase the fat-soluble of hydrophilic molecules, with it is safe and efficient the characteristics of.
By liposome technology, or the compound of the materials such as medicine and phosphatide is formed, hydrophilic substance can be wrapped in thin In aqueous medium, so as to improve the fat-soluble and stability of drug molecule.Correlative study is see JP Colletier, et al. (2002)BMC Biotechnol.2:9-16;CN1421246A, Zhang Lei, etc., 2009,《Pharmacy and clinical research》17:81-84; F.D.Cui,et a l.(2006)J CONTROL RELEASE.114:242-250;D.Y.Lee,et al.(2007)J CONTROL RELEASE.123:39-45.But in these researchs, the hydroaropic substance such as protein, low molecular weight heparin, and It is not dissolved in hydrophobic phase really, and whole system is also presented with solid-state, rather than be a kind of single-phase, stable, clarification liquid Liquid solution.In addition, for technological process, above-mentioned technical proposal is required to be removed by means such as rotary evaporation, freeze-dryings Solvent, thus increased equipment cost and production cost.
Patent US5719039 obtains a kind of non-aqueous solution containing protease, and it is under the conditions of suitable pH, will to contain The aqueous solution and isooctane solution containing Aerosol OT for having protease mix, protease to be formed and surfactant from After sub- compound, water phase is removed by the method for extracting, the protease being dissolved in organic phase is combined with surface active agent ion Thing forms single phase soln of stabilization in after drying, being soluble in acetone and other organic solvent.But it is organic in field of medicaments Solvent has strict residual quantity to limit.
Technical scheme disclosed in patent CN01115327.X, is that the aqueous solution containing insulin is mixed with parents' material Close, it is final to obtain the oil-phase solution containing insulin.Similar AmaniElsayed will contain insulin-chitosan complexes The aqueous solution, with parents' material mixing, final oil-phase solution of the acquisition containing insulin.Amani Elsayed,et al.(2009) EUR.J.PHARM.BIOPHARM.73:269–279.Due to using water as hydroaropic substance(Such as insulin)Decentralized medium, And not the step of above-mentioned preparation does not remove moisture removal, it is seen that these preparations are simultaneously not belonging to the hydrophobic preparations of hydrophilic molecules, but Water-In-Oil(W/O)Type emulsion.
RRC knobs are in the technical scheme disclosed in patent CN97193180.1, CN97196069.0, and C.L.Li Research(C.L.Li,et al.(2004)J.Pharma.Pharmaco l.56:1101-1107), its hydroholic solution is able to Realization has two essential steps:With water as decentralized medium, hydroaropic substance is dissolved in water phase;Water with contain Parents' medium it is hydrophobic mix after, and by the drying means such as freeze-drying method remove moisture.From these preparation processes From the point of view of, the preparation method of above-mentioned hydrophobic sol is, by the moisture in w/o type preparation, water removal to be gone by means such as freeze-dryings Point, it is different that this has no two with the preparation method of the lyophilized emulsion formulation that those skilled in the art are understood.On the other hand, moisture removal is being removed During, freeze-drying high energy consumption and low production efficiency, and the drying means such as other spray drying processes, again can be to stabilization Property difference medicine(Such as protein)Impact.
A kind of preferable hydrophilic molecule hydrophobic preparations are preparation process is simples, without special installation, with low cost, and The auxiliary material for being used is the material that will not bring potential safety hazard.Importantly, hydrophilic molecule not with water or the aqueous solution as point Dispersion media, in hydrophobic preparations hydrophilic molecule activity will not only lose, and can in the period of more long in keep.
