Definitions
- the present invention relates to a method for preventing adhesion formation using a protease inhibitor. More specifically, the present invention relates to a method for preventing adhesion formation using a serine protease inhibitor, particularly a chymase inhibitor.
- Postoperative adhesion formation is a major complication following common orthopedic or plastic surgery, eg, heart, chest, gynecology, ophthalmology and abdomen. Pericardial adhesions cause significant problems and increase the morbidity and mortality of reoperational cardiac surgery (J. Invest. Surg. 14: 93 ⁇ 97, 2001). Postoperative peritoneal adhesions are a major cause of complications, such as intestinal atresia, infertility, and pain, in severe cases after abdominal or gynecological surgery (Dig. Surg. 18: 260-73, 2001: Non-Patent Document 2). Many causes have been implicated in adhesion formation, including trauma, dryness, local anemia, infectious peritonitis, and endometriosis, but the pathophysiological nature of adhesion formation is not fully understood .
- Post-operative adhesions generally occur as a result of a normal wound healing response within 5-7 days after injury. Adhesion formation and non-adhesion re-epithelialization are alternative pathways, both of which start with the action of coagulation, It is thought that this will lead to the construction of a trick. If fibrin deposits are not excessive or removed, fibrin can form fibrin cross-links and form fibrin matrices, thus providing a reserve for adhesions. Crosslinks form the basis of the adherent tissue by cellular elements, including fibroblasts.
- peritoneal fibrinolytic enzyme protection systems such as the Brasmin system can remove fibrin germana1 and ricks, but surgery dramatically reduces fibrinogen degrading activity, thus creating adhesions.
- the choice of pathway for formation or re-epithelialization is determined by the surface of the damaged tissue and the extent of fibrinolysis.
- Non-Patent Document 3 attempts to prevent fibrin deposition have included the use of peritoneal washings to flush fibrinous exudates, surgical techniques to minimize local anemia, and the use of barriers to limit the adhesion of the treated serosal surface. Instead, anti-inflammatory agents such as corticosteroids and non-steroids have been widely used (Clin. Exp. Gynecol. 28: 126-127, 2001: Non-Patent Document 4).
- Non-Patent Document 5 A method for removing fibrin deposits by degrading bupurin with a conventional proteolytic enzyme after skeletal formation is under study (Int. Surg. 83: 11-14, 1998: Non-Patent Document 5). A universally effective method for preventing or treating postoperative adhesions has not yet been proven.
- Mast cells play an important role in inducing the allergic inflammatory response.
- Mast cells express on their surface receptors that bind the Fc portion of IgE and certain classes of IgG, allowing antibodies to bind to their surface.
- the interaction between the bound antibody and the antigen results in histamine, serotone, cytokin, and other allergic, Transmitters, such as various enzymes, are released that oppose the development of a sensitive response.
- Transmitters such as various enzymes, are released that oppose the development of a sensitive response.
- mast cells are involved in peritoneal adhesion formation (Am. J. Surg. 165; 127-130, 1993: Non-Patent Document 6).
- Chymase is a chymotrypsin-like serine protease contained in the secretory granules of mast cells. Chymase is a site power-in that activates stem cell factor and has the ability to induce mast cell accumulation. For example, it has been reported that chymase activity was significantly increased in a mouse treatment site after cecal abrasion (J. Surg. Res. 92: 40-44, 2000: Non-Patent Document 8). Thus, chymase-positive mast cells appear to play a role in the development of adhesion formation. However, the pathophysiological role of chymase in the development of adhesion formation remains unclear.
- chymase inhibitors eg, -aminoalkylphosphonate derivatives ⁇ and other serine protease inhibitors are used to form adhesions to peritoneal or pleural cavity organs and other body parts after wounds caused by surgery or accidents in mammals
- a method for preventing or suppressing adhesion formation between tissue surfaces in a vertebrate subject by administering to a site on the tissue surface of the subject for a period of time sufficient for tissue repair to prevent or suppress remodeling Offered.

After evaporation of the organic solvent, the remaining solution was cooled to room temperature, and 400 niL of methanol was added to the solution and allowed to crystallize at -20 ° C.
- the crystal was crystallized from acetone and recrystallized in the same manner to remove the inactive enantiomer (D-form) to obtain Boc-Pro-L-PheP (OPh) 2 .
- the remaining solution was concentrated in vacuo, and toluene-ethyl acetate (5: 1) was added as a solubilizing agent to yield 5.10 g of enantiomer and purified on medium pressure silica gel.
- Boc-Pro-L-Phe p (OPh) 2 (4.98g, 9.05 mmol) was dissolved in 37mL of cold HC1 / Jioki San (4.9 N), and stirred at room temperature for 1 hour. The solution was evaporated and dried in vacuo. The residue was dissolved in 40 niL of DMF, and Boc-Val (2.06 g, 9.50 mmol) and HOBt (1.35 g, 9.96 mmol) were added to the solution. WSCD (1.77 mL, 9.96 mmol) was added dropwise to this solution while being dripped or cooled with ice, and the mixture was stirred at room temperature.
- Boc-Pro-L-Phe p (OPh) 2 (5.86g, 8.47 mmol) was dissolved was added to 35mL of cold HClZ Jioki San (4.9 N), and stirred at room temperature for 1 hour. The solution was evaporated to dryness in vacuo. The residue was dissolved by adding 35 mL of DMF, and succinic anhydride (1.02 g, 10.2 minol) was added. Triethylamine (2.36 mL, 16.9 mmol) was added dropwise to this solution and stirred at room temperature for 2 hours. While cooling with ice, the pH of the solution was adjusted to pH 1.0 with HC1 solution, and ethyl acetate was added to extract the sample.
- the extract was washed with saturated brine solution, dried over MgSO 4, to yield the product as Kiiroo I le, filtered in vacuo and concentrated.
- the oil was concentrated by reverse phase HPLC (separation tube: YMC ODS SH-363-5, 30 X 250 mm, mobile phase: 0.1 TFA, gradient 40-70% MeCN), and 2.30 g (42%) of white powder was obtained.
- the product was produced and cooled and dried.
- Adhesion degree 2 Adhesion between several parts of the heart and surrounding tissues is observed, but by towing, the adhesions can be exfoliated and the heart can be exposed.
- adhesion degree 4 was 3 cases (37.5%), adhesion degree 3 was 2 cases (25%), adhesion degree 1 was 1 case (12.5%), and the rest was 0 (25%) In contrast, in the Suc-Val-Pro-L-PheP (OPh) 2 administration group, adhesion degree 4 was 1 case (12.5%), adhesion degree 2 was 1 case (12.5%), and the rest was 0 ( 75%), and the degree of adhesion was significantly reduced.
- the agent for preventing, suppressing or treating adhesion formation of the present invention is useful for preventing adhesion by intravenous administration, oral administration or transdermal application, and is useful after orthopedic or plastic surgery. It is useful not only for adhesions of inflammatory organs but also for adhesions of inflammatory organs.
