Definitions

  • the intima On the inner wall of the artery, the intima, accumulate in humans as well
  • Mammals remove hydrophobic plaques with increasing age or with pathological conditions, which lead to hardening of the arterial walls, to lesions and to a reduction in the inner lumen by the formation of a neointima in the vessels.
  • pathological phenomena such as cardiac arrhythmias, thrombus formation and thromboses, cerebal infarcts, cerebral thromboses,
  • holoenzyme a complete enzyme (holoenzyme) and / or a novel, smaller enzyme fragment that can be produced from this enzyme in the pharmaceutical formulations according to the invention.
  • the proposed holoenzyme is a hyaluronate lyase and the fragment also has hyaluronic acid-splitting activity. This activity leads above all to a preferred breakdown of hyaluronic acid.
  • the invention relates to new enzyme fragments produced by a special enzymatic degradation process.
  • hyaluronic acid belongs to the glycosaminoglycans.
  • Glycosaminoglycans are found in the tissues of all vertebrates.
  • Hyaluronic acid is particularly present in the intercellular matrix, the skin and the cartilage, as well as in body fluids such as the synovial fluid and the aqueous humor of the eyes.
  • Hyaluronic acid has the property of binding water with the formation of viscous, hydrocoid solutions and of forming complexes that are difficult to dissolve with strongly basic proteins. It consists of glucuronic acid and acetylated glucosamine, which are connected by ß- (l-3) - glycosidic bonds. These disaccharide units are in turn connected to one another by glycosidic ⁇ - (1-4) bonds.
  • the hyaluronic acid is split by enzymes, which are summarized with the umbrella term hyaluronidases.
  • hyaluronidases describes - incorrectly in an enzymologically systematic sense - three different hyaluronic acid-cleaving enzyme types (J. Ludowieg: The mechanism of hyaluronidases, JBC 236, 333-339, (1961)).
  • endohydrolases that hydrolytically cleave the ⁇ - (1-3) bonds with the addition of water. They include the majority of hyaluronidases from higher organisms, for example those used medically Bovine testicular hyaluronidase.
  • hyaluronate glycan hydrolases EC 3.2.1.35/36
  • Another type is the endo-ß-hyaluronidase from the leech, which cleaves the ß- (l-4) -binding highly specifically. All of the enzymes mentioned are hydrolytic hyaluronidases or hyaluronidases in the narrower sense.
  • the third type of enzyme cleaves the hyaluronic acid in the ß (1-4) bonds according to an elimination mechanism with the formation of a double bond in the (4-5) position on the glucuronic acid.
  • Hyaluronate lyases are therefore not hyaluronidases.
  • Hyaluronate lyases occur in microorganisms. For example, they are found in Streptomycetes and other bacteria. Their common characteristic is their narrow specificity towards hyaluronic acid. Other glycosaminoglycans are usually split to a negligible extent (J.-H. Ozegowski et.
  • microbial hyaluronate lyases are high molecular weight proteins with molecular weights between 1 16,000 to 120,000 daltons. These high molecular hyaluronate lyases are mostly relatively sensitive to denaturing agents and extreme physiological conditions. Particularly in the preparation of pharmaceutical and veterinary formulations, there can be considerable loss of activity due to denaturing processes. In addition, the diffusion ability of the relatively large enzymes is significantly less than the diffusion ability of smaller molecules. Theoretically, this limits the diffusion and thus the promotion of penetration or diffusion of the high-molecular hyaluronate lyases (holoenzymes) into the tissues, for example also into the plaques. A lower immunogenic effect is likely.
  • Bovine testicular hyaluronidase is used to make animal and human tissues more permeable. It serves as a penetration or absorption accelerator for subcutaneously or intramuscularly administered drugs or to facilitate the perfusion of larger quantities of fluids and faster ones Regression of edema.
  • bovine testicular hyaluronidase can be used to therapeutically influence arterial vascular diseases in humans, in particular to improve the blood flow to peripheral vessels (e.g. Thurnherr and Koch, cited at Wolff: Treatment results with intravenous magnesium comp./Hylase -Mixed injections in arteriopathies of the pelvic type in stage II. Medical training, 1972, 66, 446 - 447).
  • Wolff reported that hyaluronidase from bovine testicles with the simultaneous use of magnesium ions, administered intravenously (mixed injection, three times 300 IU per week for 6 weeks), improved the blood flow to the vessels in 90% of the examined patients with stage II arteriopathy.
  • Grosshennig in: Results of the treatment of degenerative arterial vascular diseases of the lower extremities with intravenous administration of magnesium compositum "Scharffenberg” and hyaluronidase. Dtsch. Ges.-ève, 1965, 21, 869 - 872) performed a similar mixed treatment for degenerative vascular diseases of the lower extremities as well as patients with high-seated pelvic-type degenerative vascular obliterations with "impressive success.” He gave 300 IU three times a week for about 5 weeks. In some severe cases, 30 injections were made.
  • follow-up examinations were 6-8 weeks after the end of treatment no deterioration of the achieved state can be determined.
  • Gottlieb also proposed (US 3,708,575) to treat vascular diseases in humans such as cardiac arrhythmias, thromboses, cerebral infarcts, cerebral thromboses and heart attacks, in particular atherosclerosis, with this hyaluronidase or hyaluronate lyase.
  • An isotonic sterile solution for example 10,000 IU / ml, is injected intravenously, intraarterially or intrathecally.
  • the enzyme was obtained from animal material in accordance with the information in the property right (US 3,708,575). From the description of the invention it is clear that the enzyme (s) used is the use of testicular hyaluronidases.
  • hyaluronidase from bovine testicles is suitable for increasing the permeability of blood vessels to the blood stream by dissolving, breaking down or rendering atheromatous deposits and possibly constituents of blood clots and blood thrombi.
  • the constituents of the blood thrombus that may be detached could be plaque particles that have detached from the intima and on which a blood thrombus has formed.
  • hyaluronidase of animal origin in particular hyaluronidase from bovine testicles, is that the enzyme carries with it the risk of transmitting viruses, BSE (bovine spongioform encephalopathy) and other infectious material due to its origin.
  • BSE bovine spongioform encephalopathy
  • Another disadvantage is that in the production of hyaluronidase to remove impurities in the form of ingredients, in particular foreign proteins, a very large amount of cleaning is required. In order to obtain sufficient amounts of hyaluronidase, correspondingly large amounts of starting material have to be collected under conditions in which spoilage is prevented.
  • the hyaluronidase from mammalian testicles also hydrolyzes the sulfated glycosaminoglycans present in the vessel wall.
  • Dermatan sulfate or chondroitin sulfate, heparin and heparan sulfate are believed to prevent blood clots from attaching to the inner wall of the vessels due to their anticoagulant properties.
  • the hydrolysis of these compounds increases the secondary formation of blood clots at the intima and thus the testicular hyaluronidases could also have an unfavorable side effect. Sawyer et. al.
  • EU 193330 B1 describe the production and use of a special endo-ß-glucuronidase with a molecular weight of 28,500 D from a leech to stimulate the flow of physiological fluids in eye diseases.
  • This enzyme is highly specific for hyaluronic acid and differs from one Known endo-ß-glucuronidase from the leech (Hirudo medicinalis) due to its higher stability at higher temperatures and extreme pH values.
  • the aim of the present invention is to avoid the disadvantages of the previously proposed use of hyaluronidases of animal origin as a plaque-degrading enzyme by using enzymes obtained from microorganisms in suitable galenical formulations for therapy and for preventing atherosclerotic vascular changes.
  • Microbial enzymes can in principle be obtained in a simple way through the possibilities of their biotechnological production.
  • the use of the fragments is expected to be more stable in the pharmaceutical formulations, to be less immunogenic when used and to penetrate better.
  • the enzymes provided according to the invention should not negatively influence the living mammal organism when longer enzyme activities are applied over longer periods of time.
  • the enzymes are also said to cause only a limited cleavage of the sulfated glycosaminoglycans, in order on the one hand to bring about a dissolution of plaques and of constituents of blood clots that is comparable to hyaluronidase from animal testes.
  • the severely limited breakdown of the sulfated glycosaminoglycans in the intima should not lead to the increased risk of secondary blood clots forming due to the lack of sulfated glycosaminoglycans.
  • the invention is therefore based on the object of finding plaque-degrading enzymes of microbial origin which, as constituents in pharmaceutical formulations, have a comparable or better effect with hyaluronidase from bovine testicles in dissolving plaques or in reducing the inner vessel walls occupied by plaques and of components of the thrombus and blood clots when used in the blood vessel system, have a favorable effect on the course of the disease in vascular diseases, are not toxic and have no other negative effects when used in humans or animals as an injection.
  • the present invention accordingly includes pharmaceutical formulations suitable for the treatment of vascular diseases which occur directly or as a result of atheromatous plaque formation.
  • the invention also includes a new enzyme fragment, its production and use.

  • the fragments according to the invention can be produced by proteolytic digestion of the bacterial hyaluronate lyases with proteases, preferably a protease, which cleaves the C-terminal peptide bond from aromatic amino acids.
  • the hyaluronate lyase with a molecular weight of 1 16,000 daltons from Streptocoecus agalactiae is cleaved into an enzymatically active hyaluronate lyase fragment.

  • the fragment is distinguished by a significantly higher stability in aqueous solutions and against denaturing agents.
  • the fragment has a specific activity between 400,000 IU / mg to 800,000 IU / mg and thus has the same or even a higher specific activity than the holoenzyme with a specific activity of 400,000 IU / mg.

  • the cleaning steps and the use of pyrogen-free additives ensure that the injection product is free of pyrogens.
  • the enzyme After increasing the ionic strength by adding ammonium sulfate to a saturation of 40%, the enzyme is adsorbed on phenylsepharose. The desorption then takes place with a neutral, buffered aqueous solution which contains 25% ammonium sulfate, based on 100% saturation.
