Definitions

  • the invention relates to agents for the treatment of acute and chronic infections with pathogenic for humans and animals viruses, which assemble on the cell membrane and are released by budding from the cell surface.
  • infectious diseases such as AIDS, hepatitis, hemorrhagic fever, SARS, smallpox, measles, polio or flu.
  • the invention relates to agents which contain inhibitors of protein folding as active ingredients. These include inhibitors of cellular folding enzymes (the enzymatic chaperones) as well as substances that interfere with the folding of proteins by chemical chaperones. These agents disrupt the highly organized processes of assembly and proteolytic maturation of Vims structural proteins. As a result, the release and production of progeny infectious viruses are prevented.
  • These agents have a broad spectrum of activity and can therefore be used as novel broad-spectrum antivirals for prevention or for the therapy of various viral infections.
  • virus proteins The so-called late processes of virus replication involve the re-synthesis of virus proteins, the virus structural proteins generally being expressed first after activation of viral gene expression. These structural proteins will then go into the process of assembling and forming viral substructures. In the case of enveloped viruses, this process usually takes place on cellular membranes, usually on the inside of the cell membrane. Alternatively, there is also the possibility that virus proteins first assemble into virus-like particles in the cytosol of the cell or the cell nucleus and later these virions are enveloped with a lipid membrane by processes of release from the cell membrane. Viruses that assemble on the cell membrane are usually released from the cell membrane through active budding. This results in the formation of a virus bud, which is actively erased from the cell membrane and then finally released by constriction from the cell surface in the form of a progeny virus.
  • HTV The principles of the late processes of virus replication are to be illustrated using the example of HTV.
  • Major components of HIV structural proteins are in the form of three Polyproteins translated: Gag and Gag-Pol for the inner core proteins and viral enzymes as well as Env for the viral envelope proteins.
  • membrane targeting signals in the NH 2 -terminal domain of Gag are crucial for the transport of Gag to the cell membrane.
  • the complete proteolytic processing of the Gag polyprotein Pr55 results in the formation of the matrix (MA), the capsid (CA) as well as the nucleocapsid (NC) and the COOH-terminal p6 gög protein.
  • HTV virions are generally pinched off the plasma membrane as immature non-infectious virus particles; this process is known as virus budding.
  • the proteolytic processing of Gag and Gag-Pol polyproteins begins with the activation of the viral protease (PR).
  • PR viral protease
  • the proteolytic maturation of the virions is accompanied by morphological changes. Characteristic is the condensation of the inner gore, which results in the formation of a cone-shaped core cylinder typical of the mature virus (summarized in Krausslich and Welker, 1996; Swanstrom and Wills, 1997).
  • Low molecular weight substances such as glycerol, trimethylamines, for example trimethylamine-N-oxide (TMAO), various amino acid derivatives, such as betaine, as well as deuterated water (D 2 O) have been described as "chemical chaperones". They are known to regulate protein folding by regulating the amount of water bound to protein structure (Perlmutter, 2002; Diamant et al., 2001; Gekko & Timasheff, 1981.)
  • DSG interacts with the proteins of the Hsp70 and Hsp90 families as well as with the constitutively expressed proteins of the Hsc70 family (Nadler et al., 1992).

Abstract

L'invention concerne des agents permettant de traiter des infections aiguës et chroniques avec des virus pathogènes pour l'homme et l'animal, qui sont assemblés à la membrane cellulaire et sont libérés de la surface cellulaire par germination. On recense cet effet, en particulier des agents pathogènes de maladies infectieuses comme le SIDA, l'hépatite, la fièvre hémorragique, le SRAS, la variole, la rougeole, la polio ou la grippe. L'invention concerne des agents qui contiennent comme principes actifs des inhibiteurs du plissement de protéines. On recense à cet effet des inhibiteurs d'enzymes de plissement cellulaires (enzymes chaperonnes), ainsi que des substances perturbant le plissement de protéines par enzymes chaperonnes chimiques. Ces substances englobent les catégories de substances suivantes et leurs dérivés : geldanamycine, déoxyspergualine, 4-PBA ou herbimycine A. Ces agents perturbent les processus hautement organisés de l'assemblage et de la maturation protéolytique de protéines de structure virale. La libération et la production de descendants de virus infectieux s'en trouvent entravées.
