Definitions

  • This invention is attributed to the fields of pharmaceutical biotechnology and biomedicine. It comprises the extraction of enzyme complexes from Streptomyces gougerotii 101, preparation of multienzyme biopreparations and their practical application.
  • Wound healing which is initiated and regulated by central nervous and immune organism systems, has four stages: inflammation, migration (granulation), epithelialization and scar maturation (as seen in picture 1). The same processes happen during the aforementioned wound healing, independently from their origin, tissue wound contamination or other factors.
  • a blood clot forms upon breaking skin and blood-vessels underneath it.
  • Thrombocytes within a clot excrete cytokines and growth factors: PDGF, EGF, IGF-1, FGF, TGF ⁇ .
  • PDGF central nervous system
  • EGF EGF
  • IGF-1 IGF-1
  • FGF FGF
  • TGF ⁇ TGF ⁇
  • Inflammation stage is an important and complicated process. Wound is open, thus creating a high infection risk, as damaged and necrotized tissue are a favourable medium for pathogenic microorganisms.
  • Basic immune response lasts for 25 hours. Even though inflammation is a required process, it also slows down regeneration and can be harmful. Sometimes infection or acute inflammation can complicate the inflammation stage and it can last from 20 days to 2 years. Delayed inflammation stage hinders healing and other processes, thus wounds become chronic and slow healing; hypertrophic scar might form, impeding the functions of surrounding undamaged tissues.
  • Inflammatory wound healing stage starts upon all the required factors and immune cells reaching the wound through a circulatory system.
  • Neutrophils come first and dominate the damaged place during the first 3 days. Their main function is the phagocytosis of microbes and foreign bodies. After phagocytosis is finished, neutrophils experience apoptosis and are removed by macrophages migrating into the wound. Maximal macrophage concentration in a wound is reached after ⁇ 24-36 h. Macrophages, just like neutrophils, phagocytize microbes, other particles, and clean the wound surface. Moreover, macrophages activate NK cells, which start synthesizing interferon gamma (IFN ⁇ ), which in turn activates macrophages themselves.
  • IFN ⁇ interferon gamma
  • macrophages have another important function - they attract to the damaged place and activate adaptive immunity cells, T and B lymphocytes. After arriving to the damaged place, activated T-lymphocytes start synthesizing IFN ⁇ , which, as it was already mentioned, activates macrophages and amplifies their influence. It must be mentioned that immune system cannot fight all microorganisms, thus infection can spread further than the primary place of infection and cause sepsis - acute whole-body inflammation.
  • Patent WO 2013/109004 A1 describes a wound covering of chitosan-silver nanoparticles, which has antibacterial and slow release properties, however slow antibacterial effect also lengthens the fight with an infection.
  • antibacterial compounds whose influence is based on an inhibition of enzymes synthesized by pathogenic microorganisms, e.g.
  • Patent US 2014/0134210 A1 describes an infection treatment method using antibiotics together with immunostimulator lysophosphatidylcholine, which stimulates immune cells: monocytes, macrophages, T-lymphocytes and neutrophils. Research proved that a synergetic action of those two compounds is more effective for treating infections than their effect separately.
  • Patent US 2014/0171358 A1 describes antibacterial compositions of one or more fatty acids: DGLA, 15-OHEPA and/or 15-HETrE, which can be used in combination with antibiotics. Antimicrobial effect of lipases is described in a patent US 2014/0193889 A1 . Lipases degrade microorganism cell walls and cell membrane components, thus impeding their growth and reproduction. There is a known medical preparation Flaminal®, containing enzymes glucose oxidase and lactoperoxidase. Preparation SertaSilTM with an anti-infection effect described in patent WO2010/079209 A2 , contains enzyme serratiopeptidase.
  • TNF- ⁇ stimulates the synthesis of proteases, such as: elastase, myeloperoxidase, acid hydrolase, collagenase and lysosomes, within neurophils and macrophages degrading necrotic tissues. Additionally, the inhibitors of these proteases, suppressing the protease activity on the wound bed, are secreted, so as not to damage live tissue. This inhibition slows down the removal of necrotic tissues from the wound, thus lengthening both the inflammation stage and an overall wound healing duration. Moreover, inflammation cells are an important growth factor and the source of cytokines, initiating wound healing proliferation stage.
  • Patent US 2014/0207050 A1 describes a method of using anaesthetics together with electrostimulation, thus inducing contractions of local and deep muscles, which in turn improve blood circulation and increase oxygen concentration in a wound; wound healing process is quicker and there is lower risk of complications.
  • Tissue removal is a medical removal of dead, damaged or infected tissue in order to improve wound healing and regeneration of a healthy tissue.
  • debridement There are a few methods of debridement: surgical, mechanical, autolytic, enzymatic, etc.
  • Autolytic debridement intensifies natural autolytic processes in a wound, sustains moist environment and regulates the excess of exudate.
  • Autolytic debridement is a long process, which cannot be applied to infected wounds. Mechanical removal of necrotic tissues can damage healthy tissues both within the wound and around it, and isn't selective.
  • Surgical debridement is painful, can elicit bleeding, requires the use of pain suppressants, plus a part of healthy tissues is lost.
  • Enzymatic debridement is especially selective and local method applied for the treatment of slowly healing wounds. Exogenous enzymes, usually proteases, effecting in combination with endogenous enzymes formed within a wound, are used for this method.
  • Enzymes performing debridement can be extracted from plants, microorganisms or animals.
  • Bromelain a protease of vegetative origin, is frequently used as an active component in medical preparations for debridement, and is described in patents: US 2013/0156745 A1, US 8119124 B2 and US 8128589 B2 .
  • Bromelain is a cysteine endopeptidase derived from pineapples.
  • Bromelain preparation 'NexoBrid' is used to treat skin burns.
  • Preparation Accuzyme ® has an active component enzyme papain, which performs debridement.
  • papain is a proteinase derived from papaya fruits. Its advantage against other proteinases is an ability to act in a wide pH range (3 to 12). However papain alone is not so effective, thus it's used together with urea, which denaturates dead proteins and allows them to be degraded by papain. Clinical study showed no significant effect on faster wound healing.
  • Patent RU 2280076 C1 describes enzymes of animal origin. Enzymes, extracted from Kamchatka crab, display collagenasic, proteasic, ribonucleasic, deoxyribonucleasic, phosphodiesterasic, phosphatasic, amylasic, lipasic and glucanasic activities. Due to this reason, complexes of those enzymes or individual enzymatic preparations can be widely used in biotechnology, medicine and cosmetology. Patent authors state that this multipurpose preparation is suitable for the treatment of festering wounds and is more effective than preparations containing only collagenases or proteases; however not any single preparation or its application study are described.
  • Preparation Elase ® uses a mixture of two enzymes: fibrinolysin and deoxyribonuclease.
  • Fibrinolysin degrades fibrin and dissolves blood clots, also inactivates fibrinogen and some clotting factors. This enzyme widens blood vessels on the wound bed. By degrading fibrin and necrotic tissues, it helps the macrophages to enter the wound. Dry fibrinolysin is stable, but dissolved loses its activity after 6-8 hours. Fibrinolysin reaction products are not resolved, thus they must be removed from the wound surface.
  • Deoxyribonuclease is extracted from cattle pancreas. This enzyme degrades nucleic acids and lowers the viscosity of exudate. It is soluble in water and active in a wide pH range, but loses its activity in a room temperature.
  • Endopeptidase trypsin extracted from pancreas, removes necrotic tissues without damaging live tissue. Clinical trials determined that this enzyme can increase re-epithelialization, increase blood circulation and lower the formation of oedemas within wounds. However, more extensive clinical trials are required before the efficacy of this enzyme wound treatment is determined.
  • the most known preparations with trypsin are Xenaderm ® and Granulex ® .
  • Preparation Santyl® designed for wound cleaning and treatment, has microbiological collagenase isolated from Clostridium histoliticum in its composition. This protease selectively degrades distinct collagen within the necrotic tissues, but is useless against keratin, fats and fibrin.
  • the optimal activity pH for this collagenase is 6 to 8.
  • Preparation Varidase ® also contains two enzymes: streptokinase and streptodornase.
  • Streptokinase is produced by ⁇ -hemolytic streptococci. This enzyme transforms plasminogen into plasmin, thus stimulating the fibrolysis of wound exudate.
  • Streptodornase is produced by hemolytic streptococci. This enzyme is a deoxyribonuclease, which performs DNA hydrolysis without any damage to live cells.
  • Patent US 2003/0198631 A1 describes a medical enzymatic preparation for debridement with extracellular metalloendopeptidase 'Thermolysin' , isolated from microorganism Bacillus thermoproteolyticus .
  • This protease is characterized by high specificity for two proteins: collagen and fibrin. Due to this specificity, the preparation can perform only a few functions during a complex wound healing process.
  • Fibroblasts, keratinocytes and endothelium cells start synthesizing growth hormones once the wound is cleaned from microbes and necrotic tissues (table 1).
  • TGF- ⁇ Cell Synthesized growth factor Keratinocytes TGF- ⁇ , TGF- ⁇ , IL-1 Fibroblasts IGF-1, bFGF, TGF- ⁇ , PDGF, KGF, CTGF Endothelium cells bFGF, PDGF, VEGF
  • A, so called, granulation tissue forms in a damaged place from endothelium cells, fibroblasts, keratinocytes, inflammation macrophages, lymphocytes and intercellular matrix.
  • Proteases perform an important function in a cell migration stage. Collagenase, elastase and trypsin degrade desmosomes and hemidesmosomes, and thus help fibroblasts and endothelium cells separating from basement membrane on the wound bed and freely migrate into a wound cavity. Also, protease inhibitors, suppressing protease activity on the wound bed, are secreted into the wound, in order to prevent damaging live tissue.
  • Collagen fibrils are being constantly remodeled by proteases secreted by neutrophils, macrophages, fibroblasts, endothelium and epithelium cells. Re-epithelialization happens simultaneously - wound is covered in a layer of epithelium cells, while new blood vessels are being formed. Fibroblasts synthesize collagen, elastin and proteoglycans, which form the primary scar.
  • Scar maturation can last from a few months to a few years, depending on the origin and size of wounds. Scars of simple cuts or slash wounds mature in 1 to 2 months, while of burns can last 30 or more months. An upset fibroblast function increases collagen synthesis, thus inciting the formation of hypertrophic and keloid scars. During this stage it is prudent to use preparations with collagenase.
  • Patent WO2010079209 A2 describes preparation SertaSil TM for the treatment of various wounds, and whose main active component is proteolytic enzyme serratiopeptidase. This protease has been isolated from a non-pathogenic microorganism Serratia E 15 . Patent describes the functions this preparation performs in a wound: fights an infection, effectively removes necrotic tissue, soothes pain, regulates the amount of exudate, regulates wound moisture balance, decreases wound inflammation and oedemas, reduces bleeding.
  • Patent WO 2011104630 A1 describes an enzyme complex, formed of proteases, carbohydrolases and lipases, and isolated from a fungus Conidiobolus brefeldianus culture. These enzymes can be used separately or in mixtures.
  • Authors present possible application areas: leather (animal fur) treatment, detergents, food, textile, silk production and the utilization of its byproducts, analytic reagents, pharmacy, cosmetics, molecular biology and etc.
  • leather animal fur
  • detergents e.g., aqueous fungus fungus brefeldianus culture
  • analytic reagents e.g., fungus Conidiobolus brefeldianus culture.
  • Patent US 2013/0202581 A1 describes compositions for wound treatment, which use three hydrolases extracted from pancreas: protease, lipase and amylase. Authors say that these enzymes can be used in different concentrations for the creation of wound treatment preparations. It is also noted that these hydrolases stimulate epidermis cells, thus speeding up wound healing and preventing the formation of scars. It is also said that these enzymatic compositions are not effective against infections caused by Staphylococcus aureus and Escherichia coli .
  • Enzymes are also used in cosmetic products; most frequently in skin cleansers. Enzyme based skin cleansers do not contain acids or scrubbing granules, which can irritate skin. The working principle of those cleansers is the dissolving of dead skin cells by enzymes. Skin care product market has products working on a similar principle. Enzymes used in cosmetics can be extracted from different sources. A few examples of such sources are presented further. Patents US 5705166 , US 6416769 B1 and US 8377434 B2 describe enzymes used for the production of skin cleansers and extracted from unripe papaya fruits. Patent CA 2377357 describes enzymes used for cosmetic products and extracted from Atlantic cod ( Gadus morhua) .
  • Patents US 4556554 and US 2010/0080787 A1 describe enzyme complexes used for the production of skin care cosmetics.
  • Patent US 6551606 B1 describes an enzyme complex from coconut ( Cocos nucifera) milk.
  • Patent US 2005/0249720 describes enzyme complexes used for cosmetic products and extracted from pineapple, mango and papaya fruits.

  • M ultienzyme biopreparation obtainment technology is based on the extraction of enzyme complexes synthesized by Streptomyces gougerotii 101 microorganism and their use in pharmacy, production of cosmetic and antibacterial compositions. Enzymes composing a multienzyme biopreparation have following effect:
  • Wound is an open way for pathogenic microorganisms, moreover necrotic tissues and exudates create favourable conditions for their reproduction.
  • General immune response takes about 24 hours; during that time processes in a wound can complicate irreversibly, starting an infection.
  • multienzyme biopreparation compositions have a wide spectrum lytic activity and break down pathogenic microorganisms in a wound. They also hydrolyze denaturated proteins, liquefy necrotized tissue in a wound, stimulate the growth of granulation tissue, speed up the wound cleaning and healing, and lower the swelling and inflammation of nearby tissues.
  • Collagenase in a multienzyme preparation liquefies a hard layer of clotted blood, necrotic tissues and degrades the overabundance of collagen, which lowers the risk of scar formation while treating festering wounds.
  • protein-rich medium without blood circulation favourable for the growth of microorganisms, is removed; bacterial wound contamination is decreased and infectious processes are suppressed. And so, conditions for further wound healing stages, tissue regeneration and improvement in blood circulation, are made.
  • Additives within the multienzyme biopreparation composition like sodium alginate, increase the absorption of exudate.
  • Polyethylene glycol creates polymer grid, which immobilizes enzymes and prevents the loss of enzyme activity, which allows a lower amount of bandaging per day.
  • Glycerol attracts holds and bonds water.
  • Compositions with a higher concentration of glycerol create a longer lasting moist environment in a wound during all the healing stages.
  • Epithelium cells require moisture in order to easier move from the foci of re-epithelialization on the edges of the wound, and fill-in the whole wound. These cells move on the wound bed in dry wounds. In moist conditions, cells can migrate throughout the whole site of the wound and they heal faster.
  • Enzyme complexes with proteolytic, collagenasic, esterasic, amylolytic, lipasic, glucanasic, deoxyribonucleasic and lytic activities are obtained from actinomycete Streptomyces gougerotii 101 strain.
