Abstract

The invention relates to a new application of pig lung extract as Matrix Metalloproteinase (MMP) inhibitor, in particular to the application of pig lung extract in inhibiting MMP-1, MMP-2 or/and MMP-9.

Description

The Pulmonis Sus domestica extract is as the purposes of NMPI
Technical field
The present invention is relevant to the Pulmonis Sus domestica extract, and (Matrix Metalloproteinase, MMP) the new purposes of inhibitor is especially for suppressing MMP-1, MMP-2 or MMP-9 as matrix metalloproteinase.
Background technology
Metalloproteases is the ultra group of protease (ferment), and its number is in increasing sharp in recent years.Based on structure and functional consideration, these enzymes have been classified into several groups and subtribe crowd.The instance of metalloproteases comprises matrix metalloproteinase (MMP), such as collagenase (MMP-1; MMP-8, MMP-13), gelatinase (MMP-2, MMP-9), stromelysin (MMP-3; MMP10, MMP-11), a matter lysin (MMP-7), metalloelastase (MMP-12), enamel lysin (MMP-19), MT-MMP (MMP-14, MMP-15; MMP-16, MMP-17); Reproduction lysin or enamel lysin or MDC group, it comprises secretase and flows out enzyme, such as TNF invertase (ADAM10 and TACE): 3,4,3',4'-tetraketo-.beta.-carotene group, it comprises some enzymes, such as procollagen is handled protease (PCP); And other metalloproteases, for example assemble protoenzyme, endothelin-converting enzyme group and angiotonin invertase group.Wherein known MMP and multiple disease association; Like MMP when cancerous tissue medium vessels new life or the cancerometastasis; Its expression can raise or ferment can produce activation; In addition, the decomposition for extracellular matrix in the various diseases such as ulcer, beaevais' disease, osteoporosis, periodontal disease also has effect.Moreover; Active hyperfunction MMP will keep the phenomenon that important component is decomposed on the dermal composition to skin because of outside stimuluss such as ultraviolet make; Recently, because of its for since the activatory aging promotion factor of ultraviolet come into one's own especially, come into one's own especially with MMP-1, MMP-2 and MMP-9 especially; Its reason has two; The substrate of these MMP of the first is the important structure composition of skin, and two to be skin long term exposure stimulate these MMP to form under the factor of pathological states for example inflammatory reaction, oxidative stress and ultraviolet in meeting for it.Therefore, think that at present selectivity suppresses MMP-1, MMP-2 and MMP-9 and slowing down more helpful reaching effectively on the skin aging than suppressing all metalloproteases.
MMP-1 is collagen protein catabolic enzyme a kind of of common name; For regulating the photoaging important factor; Fibroblast is tanned by the sun by the ultraviolet of sunlight can cause the matrix metalloproteinase great expression, and then degradation of cell epimatrix (ECM), that is to say that MMP-1 is responsible for the collagen protein degraded of dermal tissue.
The importance that acts on the skin physiology of MMP-2 (dispergation ferment 72-kDa) also is confirmed.Though whether MMP-2 plays the part of direct role in the decomposition of type i collagen do not confirm as yet; But type i collagen be its zymolite obtained first confirm; In addition; IV Collagen Type VI (basement membrane), VII Collagen Type VI (corium-epidermis is decided the anchor microfibre), gelatin (rotten type i collagen), elastin laminin and fibrin etc. also all are the zymolites of MMP-2.Along with day at age is long, the ferment activity of MMP-2 in skin can increase, and therefore, MMP-2 also plays the part of important role aspect the atrophy of extracellular matrix.
MMP-9 (gelatinase B; 92kDa type I V collagenase; The 92kDa gelatinase) be a kind of excretory protein, it is at first purified in 1989, then asexual propagation and sequencing.Being expressed under the normal condition of MMP-9 is to be restricted to few cell types, comprises growing germinal layer, osteoclast, neutrophils and macrophage.But its expression can reach in other cell type in these same cells, and several amboceptors of mat bring out, and comprise that these cells are exposed to somatomedin or CYTOKINES.It is for often responding related identical amboceptor with the initiation inflammatory.The same through excretory MMP with other, MMP-9 disengages with not active proenzyme, and it is to divide subsequently and form the enzyme of tool enzyme activity.In in vivo supplying the needed protease of this activation, be to be the unknown.Active MMP9 is to the balance of organized enzyme not, is further in vivo via regulating with the reciprocal action of a kind of protein TIMP-1 (tissue depressant of metalloproteases-1) of natural generation.TIMP-1 is the C-stub area that is bonded to MMP-9, causes the inhibition at MMP-9 catalysis position.ProMMP-9 is through bringing out the balance of expression, and ProMMP-9 splits into active MMP9, and the existence of TIMP-1, is to merge the amount that is present in the tool catalytic activity MMP-9 of local location with decision.The MMP-9 of tool protein decomposing activity can attack and receive matter, and it comprises gelatin, elastin laminin and natural type I V and type V collagen; It does not have activity for natural type I collagen, proteoglycan or Thallus Laminariae (Thallus Eckloniae) amino acid.Data body in existing the growth, relevant with the role of MMP-9 in different physiologys and pathological process.Physiology role is included in the commitment of embryo transfer, and the embryo is grown the intrusion of germinal layer through uterine epithelium; Bone growth and developing certain role; And inflammatory cell is from the vascularity creep is extremely organized.Using the metric MMP-9 of EIA enzyme immunoassay to disengage, in fluid, and in the AM supernatant from untreated asthma patient, and from other groups of individuals person relatively, is to show the raising that lands.The MMP-9 that increases expresses and also has been found in some other pathology symptom; So make MMP-9 produce related with lysis; For example COPD, arthritis, neoplasm metastasis, Ah ear are grown extra large Mo's disease, multiple sclerosis; The speckle that reaches in the sclerosis of tremulous pulse atheroma breaks, and causes the acute coronary symptom, such as myocardial infarction.
Because the safety of natural product is good, is more and more paid attention to for the exploitation of natural origin product now, still have the natural product that needs exploitation to suppress MMP.
Summary of the invention
An object of the present invention is to provide a kind of purposes of Pulmonis Sus domestica extract, it is to be used for preparation to suppress the active compositions of matrix metalloproteinase (MMP).
The present invention describes in detail in the lower part.Further feature of the present invention, purpose and advantage can be prone to be shown in embodiment of the present invention and claims.
