Up to the present, countries in the world stay in this field of treatment staphylococcus aureus mostly to staphylococcus lysozyme.And because its enzymatic activity is extremely unstable, be difficult under the room temperature preserve, its range of application is also only at laboratory stage.
At present, except staphylococcus aureus, existing more bacterial antibiotic produces drug resistance, thereby makes that pathogenic bacterial infection is difficult to be effectively controlled.Especially antibiotic improper use, the Resistant strain quantity that is caused is increasing, the infection that these microorganisms cause, and not only curative effect is not good enough or invalid fully under the conventional therapy situation, owing to killed the profitable strain of human body itself, can also change the ecological ragime of patient's normal flora simultaneously.In addition, situation from China's investigation, cross infection is quite serious in the hospital of China, cause extra misery to patient, increase financial burden and misfortune, the primary disease that serious nosocomialtion is suffered from patient can not reach the treatment of expection, even leads to the failure, and produces the sequela be difficult to cure or causes death.
Thereby need a kind of alternative antibiotic, but broad-spectrum sterilization, and the difficult antibacterial that produces endurance strain solves above unfavorable factor.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned weak point, and a kind of lysostaphin compounded preparation that can make an addition to respectively in external medicine (comprising skin, mucosa), food preservative, health food, disinfectant for external use, the toothpaste is provided.These series of products have safe without toxic side effect, are difficult for producing drug resistance, efficient, broad-spectrum sterilization.
The invention provides a kind of lysostaphin compounded preparation, said preparation is formed 100% form by 0.1-20% staphylococcus lysozyme, 50-85% lysozyme, 1-20% antibacterial, 0.5-20% ionic compound, 0.2-30% glucosamine material, 0-20% ephedrine and 0.1-20% antistaling agent with arbitrary proportion.

A kind of antistaling agent can be a kind of in parabens, the sodium benzoate.
Staphylococcus lysozyme is a kind of bacteriolysin of gram positive bacteria.Form the aminoacid of the tetrapeptide side chain of such gram positive bacteria (for example staphylococcus aureus) whole cell peptidoglycan, be followed successively by the L-alanine, D-glutamic acid, L-lysine, D-alanine; And the first L-alanine links to each other with 3-O-.alpha.-carboxyethyl-D-glucosamine. by an amido link, and the L-lysine that this polysaccharide chains tetrapeptide side chain is the 3rd is attached on the adjacent polysaccharide chains tetrapeptide side chain D-alanine carboxyl by pentapeptide (five glycine) cross-bridge.Intersect in length and breadth thus, about connect and constitute very tough and tensile 3 D stereo loose structure, and aggregate into thicker Peptidoglycan layer.Staphylococcus lysozyme can cut off the Gly-Gly key in the Peptidoglycan.
In order to increase the stability of lysostaphin, enlarge fungicidal spectrum, we have selected lysozyme, β-1,4 glycosidic bond between lysozyme energy cracking-acetylmuramic acid C-1 and the N-acetylglucosamine C-4.Thereby make bactericidal activity stronger, reach the purpose of dissolving and killing bacteria, and can avoid the generation of bacterial drug resistance.
We have selected tens of kinds of micromolecular compounds in addition, through repeated screening, and finally selected a kind of antibacterial such as hibitane, bacteriostatic peptide, a kind of glucosamine material such as chitin, chitosan, N-acetyl-D-amino; A kind of antistaling agent such as parabens, sodium benzoate sodium benzoate.These compositions are composite with different proportionings and above-mentioned 2 kinds of enzymes respectively, add some potassium, sodium, magnesium ion chemical compound simultaneously, and identify the bactericidal effect of the complex that is produced.We find that each compound that is produced not only bactericidal effect is much higher than staphylococcus lysozyme, and 10-40 is doubly to the simple superposition of three's bactericidal effect; The fungicidal spectrum of each complex also obviously enlarges, and all can reach very strong killing action to gram positive bacteria and gram negative bacteria;
Through each complex of verification experimental verification gonococcus, staphylococcus aureus, Candida albicans, bacillus pyocyaneus, escherichia coli, Hemolytic streptococcus are all shown very strong bactericidal action.
