Description

A kind of pharmaceutical composition containing the fusion protein for suppressing blood vessel hyperplasia and purposes
It is on 08 31st, 2010 the applying date that the application is, Application No. 201010267503.7 is entitled " a kind of The divisional application of pharmaceutical composition and purposes containing the fusion protein for suppressing blood vessel hyperplasia ".
Technical field
The present invention relates to field of pharmaceutical preparations, it is related to the egg merged comprising vegf receptor fragment and immunoglobulin Fc White pharmaceutical composition, and it is in application medically.
Background technology
With the development of INVENTIONModern cell molecular biology, cell factor and cell surface correlation molecule are in ophthalmology disease Effect is widely paid close attention to and is studied, and VEGF is that vascular endothelial cell mitogenesis element has increase vasopermeability Biological nature, particularly important in generations of the fetal period VEGF to blood vessel, level declines after birth.VEGF is in low under physiological status Horizontal expression state, the function for maintaining blood vessel is necessary.Newest result of study prompting, for senile retinal blood Pipe lesion (Age-related macular degeneration, referred to as AMD), diabetic retinopathy (Diabetic Retinopathy, DR) etc. the related disease of angiogenesis all play extensive and important effect.AMD is multiple be born in 45 years old with On, its illness rate increases with the growth at age, is the important diseases of current the elderly's blinding.Moist AMD is mainly glass The destruction of film, choroidal artery constitutes CNV under invading retina, occurs under macular area retinal pigment epithelium Or serosity or hemorrhagic disciform detachment under neural epithelium, machine scar is eventually become, effectively suppress to cause wet macular disease The blood vessel endothelial cell growth factor VEGF of change, blocking VEGF or vegf receptor so as to reach angiogenesis inhibiting have it is important There is important therapeutic action.In DR, the content of VEGF is higher than normal level in cell and body fluid.VEGF increases, and causes hair Thin vascular permeability is sexually revised, and causes retina to ooze out, bleeding and macular edema, induction of vascular generation element (Angiogenin) generation increases, and collaboration promotes the formation of retinal neovascularization, causes inpairment of vision.
Sat linkage, hydrogen bond, disulfide bond and hydrophobic effect are Protein requirement conformational stability active forces.It is metal ion, substrate, auxiliary Helping the factor and interaction of other low phases to molecular weight ligands makes protein conformation stabilization.Protein and other large biological molecules The especially effect of protein and fat.In vivo, protein often interacts to form compound with lipid or polysaccharide, shielding The hydrophobic region of protein surface, so as to dramatically increasing the stability of protein.Albumen is unstable mainly to be drawn by following factor Rise:(1) physical action:The polar water molecules contact with protein hydrophobic core adjusted by Brownian movement can cause protein unstable It is fixed.(2) chemical action:The oxidation of the amino acid residue of active site is one of most common mechanism of enzyme inactivation.Such as half Guang The sulfydryl of propylhomoserin and the indole ring of tryptophan, it is especially sensitive to aoxidizing.(3) biological action:Proteolytic enzyme is acted on.Micro- life Thing and foreign protein hydrolysis enzyme effect catalysis peptide bond hydrolysis.By genetic engineering bacterium purify eukaryotic polypeptide when yield it is low, be by Caused in external proteolysis.
Polymerization makes the hydrophobic amino acid residues of embedding exposed to aqueous solvent first, causes protein reversible to be denatured; Secondly, protein molecule associates each other, to reduce the unfavorable exposed of hydrophobic amino acid;Finally, if protein molecule contains half Cystine and cystine residue, then can occur intermolecular disulfide bond exchange reaction.Polymerization sometimes can be by reduction and oxygen again Change regeneration natural disulphide bonds, be re-activated protein.Polymerization and simple precipitation are distinguishing, and the latter occurs protein Significant conformation change.
The inventors have observed that an obvious problem is that pharmaceutical solutions easily forms solvable polymerization after long term storage How thing and insoluble particle, solve this problem, finds a kind of in physics and chemically all stable pharmaceutical composition, can Suppress polymer generation, and less soluble polymer and insoluble particles can be formed after long term storage.Further, since its group It is pharmaceutically acceptable component to divide, and can be used for treating eye disease, including intravitreal injection and topical administration.Additionally, The inventors discovered that the preparation prescription for obtaining compares in syringe more stablizing in the vial.
In the present invention using can angiogenesis inhibiting, by the cell of vascular endothelial growth factor (VEGF) acceptor 1 The extracellular domain 3 and 4 (KDR-3,4) of extracellular portion 2 (Flt-2) and vegf receptor 2 and human immunoglobulin(HIg) 1 (IG1) Fc The albumen (FP3 albumen) of fusion be to be expressed by the working cardial cell of recombinant technique and medicinal pure by reaching after purification Degree, suitable pharmaceutical preparation is obtained by changing liquid formulation packing.These preparation preferred liquid preparations or lyophilized formulations, it is adaptable to eye The treatment of eyeball disease, in particular for intravitreal injection.
, used as protein drug, its stability is more far short of what is expected than common small-molecule chemical medicine, compared to naturally occurring for FP3 albumen Immunoglobulin, its stability is also worse.Fusion protein described in Chinese patent is Chinese patent " vegf receptor fusion protein Prescription described in application in disease of eye is treated " (patent No. ZL200610066257.2) is needed in -20 DEG C of preservations, right The production of medicine, transport is preserved and application is proposed requirement higher.It is well known that the stabilization of the fusion protein of general restructuring Property it is all poor, can be influenceed by various environmental factors during preservation, such as temperature, appropriateness, oxygen, ultraviolet etc. can It is that fusion protein occurs various polymerizations for physically or chemically changing, causing protein, decomposes, oxidation or denaturation etc..These changes The activity reduction of albumen can be made, therapeutic effect declines and causes serious toxic and side effect.Therefore, develop stabilization and be easy to The fusion protein formulations of transport and storage are with highly important clinical meaning.
The content of the invention
An object of the present invention be provide it is a kind of containing vascular endothelial growth factor (VEGF) acceptor 1 it is thin The extracellular domain 3 and 4 (KDR-3,4) of ectodomain 2 (Flt-2) and vegf receptor 2 and human immunoglobulin(HIg) 1 (G1) Fc Fusion protein pharmaceutical composition, can more particularly be used for the liquid preparation of intravitreal injection, the liquid preparation can make to melt Hop protein keeps stabilization, its most it is prominent be characterized in the generation and the purity that causes that can effectively suppress fusion protein polymer under Drop, so as to keep the bioactivity of active principle.
