Definitions

  • This invention is directed to pharmaceutical compositions comprising an elastase inhibitor and an (F)-actin shortening protein such as gelsolin or vitamin D binding protein (DBP), for use in the treatment of Cystic Fibrosis and related diseases.
  • an elastase inhibitor and an (F)-actin shortening protein such as gelsolin or vitamin D binding protein (DBP), for use in the treatment of Cystic Fibrosis and related diseases.
  • this invention is directed to pharmaceutical compositions comprising elastase inhibitors of Formula I
  • proteases from granulocytes and macrophages have been reported to be responsible for the chronic tissue destruction mechanisms associated with inflammation, including rheumatoid arthritis and emphysema. Accordingly, specific and selective inhibitors of these proteases are candidates for potent anti-inflammatory agents useful in the treatment of inflammatory conditions resulting in connective tissue destruction, e.g., rheumatoid arthritis, emphysema, bronchial inflammation, chronic bronchitis, glomerulonephritis, osteoarthritis, spondylitis, lupus, psoriasis, atherosclerosis, sepsis, septicemia, shock, myocardial infarction, reperfusion injury, periodontitis, cystic fibrosis and acute respiratory distress syndrome.
  • the role of proteases from granulocytes, leukocytes or macrophages are related to a rapid series of events which occurs during the progression of an inflammatory condition:
  • lymphoid cells especially macrophages and polymorphonuclear leukocytes (PMN). It has been known that a variety of proteases are released from the macrophages and PMN, further indicating that the proteases do play an important role in inflammation.
  • proteases are an important family of enzymes within the peptide bond cleaving enzymes whose members are essential to a variety of normal biological activities, such as digestion, formation and dissolution of blood clots, the formation of active forms of hormones, the immune reaction to foreign cells and organisms, etc., and in pathological conditions such as the degradation of structural proteins at the articular cartilage/pannus junction in rheumatoid arthritis etc.
  • Elastase is one of the proteases. It is an enzyme capable of hydrolyzing the connective tissue component elastin, a property not contained by the bulk of the proteases present in mammals. It acts on a protein's nonterminal bonds which are adjacent to an aliphatic amino acid.
  • Neutrophil elastase is of particular interest because it has the broadest spectrum of activity against natural connective tissue substrates.
  • the elastase of the granulocyte is important because, as described above, granulocytes participate in acute inflammation and in acute exacerbation of chronic forms of inflammation which characterize many clinically important inflammatory diseases.
  • Proteases may be inactivated by inhibitors which block the active site of the enzyme by binding tightly thereto.
  • Naturally occurring protease inhibitors form part of the control or defense mechanisms that are crucial to the well-being of an organism. Without these control mechanisms, the proteases would destroy any protein within reach.
  • the naturally occurring enzyme inhibitors have been shown to have appropriate configurations which allow them to bind tightly to the enzyme. This configuration is part of the reason that inhibitors bind to the enzyme so tightly (see Stroud, "A Family of Protein-Cutting Proteins" Sci. Am., July 1974, pp. 74-88).
  • i-Antitrypsin is a glycoprotein contained in human serum that has a wide inhibitory spectrum covering, among other enzymes, elastase both from the pancreas and the PMN. This inhibitor is hydrolyzed by the proteases to form a stable acyl enzyme in which the active site is no longer available. Marked reduction in serum ⁇ i-antitrypsin, either genetic or due to oxidants, has been associated with pulmonary emphysema which is a disease characterized by a progressive loss of lung elasticity and resulting respiratory difficulty.
  • Rheumatoid arthritis is characterized by a progressive destruction of articular cartilage both on the free surface bordering the joint space and at the erosion front built up by synovial tissue toward the cartilage. This destruction process, in turn, is attributed to the protein-cutting enzyme elastase which is a neutral protease present in human granulocytes. This conclusion has been supported by the following observations:
  • (F)-actin shortening proteins including gelsolin, plasma gelsolin (brevin), vitamin D binding protein (DBP), villin, fragmin, and severin, and their use in shortening (F)-actin and treating (F)-actin mediated diseases is described in U.S. 5,260,224, issued to Stossel et al, on November 9, 1993, which patent is hereby incorporated by reference.
  • Gelsolin's primary function in the plasma is to sever actin filaments. If gelsolin is present in excess of actin, only gelsolin-actin complexes result; if actin is in excess, there are free actin oligomers and gelsolin-actin complexes. The actin severing occurs by way of a non- proteolytic cleavage of the noncovalent bond between adjacent actin molecules.
  • Efficacious levels of actin-binding compounds may be administered so as to provide therapeutic benefits against the secondary toxic effects of excessive extracellular actin.
  • efficacious levels of actin-binding compounds is meant levels in which the toxic effects of free extracellular actin are, at a minimum, ameliorated.
  • excessive extracellular actin is meant an amount of extracellular actin which exceeds the ability of the plasma proteins to bind and clear the actin from extracellular fluids without secondary tissue damage or toxic effects.
  • secondary tissue damage or toxic effects is meant the tissue damage or toxic effects which occur to otherwise healthy tissues, organs, and the cells therein, due to the presence of excessive extracellular actin in the plasma, usually as a result of a "primary" tissue injury elsewhere in the body.

The organic layer is dried through sodium sulfate, concentrated and the residue chromatographed on silica gel. Elution with 5% of ethyl acetate in methylene chloride gives Compound 12. Analysis: C33H45N3O6 Calc: C, 68.37; H, 7.82, N, 7.25
  • the diamines used to prepare the amino amides described herein were commercially available or prepared according to the following routes
  • a mixture of 0.900 gm N-benzyl-N,N'-dimethylethyl- enediamine, 1.10 gm powdered sodium carbonate and 0.75 ml of 2- phenylethylbromide is refluxed for 5 hours. An additional 0.25 ml of bromide is added during this time.
  • the reaction mixture is then cooled and filtered.
  • the filterate is concentrated in vacuo and the residue chromatographed on silica gel using an eluent of CH2CI2/CH3OH/- NH4OH (97/3/0.3) to yield 0.875 gm of N-benzyl-N,N'-dimethyl-N'-(2- phenylethyl)ethylenediamine.

Abstract

Cette invention concerne des compositions pharmaceutiques destinées au traitement de la pneumopathie et plus particulièrement de la mucoviscidose, ces compositions comprenant une azétidinone substituée de formule (I) dont on a découvert le rôle d'inhibiteur puissant de l'élastase, et une protéine raccourcissant la (F)-actine, telle que la gelsoline.
