Definitions

  • Ras protein is part of a signalling pathway that links cell surface growth factor receptors to nuclear signals initiating cellular proliferation.
  • Biological and biochemical studies of Ras action indicate that Ras functions like a G-regulatory protein.
  • Ras In the inactive state, Ras is bound to GDP.
  • Ras Upon growth factor receptor activation Ras is induced to exchange GDP for GTP and undergoes a conformational change.
  • the GTP-bound form of Ras propagates the growth stimulatory signal until the signal is terminated by the intrinsic GTPase activity of Ras, which returns the protein to its inactive GDP bound form (D.R. Lowy and D.M. Willumsen, Ann. Rev. Biochem. 62:851-891 (1993)).
  • Mutated ras genes are found in many human cancers, including colorectal carcinoma, exocrine pancreatic carcinoma, and myeloid leukemias.
  • the protein products of these genes are defective in their GTPase activity and constitutively transmit a growth stimulatory signal.
  • Ras C-terminus contains a sequence motif termed a "CAAX” or "Cys-Aaa 1 -Aaa 2 -Xaa” box (Cys is cysteine, Aaa is an aliphatic amino acid, the Xaa is any amino acid) (Willumsen et al, Nature 310:583-586 (1984)).
  • this motif serves as a signal sequence for the enzymes farnesyl-protein transferase or geranylgeranyl-protein transferase, which catalyze the alkylation of the cysteine residue of the CAAX motif with a C 15 or C 20 isoprenoid, respectively.
  • the Ras protein is one of several proteins that are known to undergo post-trans lational famesylation.
  • Other farnesylated proteins include the Ras-related GTP-binding proteins such as Rho, fungal mating factors, the nuclear lamins, and the gamma subunit of transducin.
  • James, et al., J. Biol. Chem. 269, 14182 (1994) have identified a peroxisome associated protein Pxf which is also farnesylated.
  • James, et al. have also suggested that there are farnesylated proteins of unknown structure and function in addition to those listed above.
  • farnesyl-protein transferase inhibitors are inhibitors of proliferation of vascular smooth muscle cells and are therefore useful in the prevention and thereapy of arteriosclerosis and diabetic disturbance of blood vessels (JP H7- 112930).
  • FPTase farnesyl-protein transferase
  • FPP famesyl diphosphate
  • Ras protein substrates
  • the peptide derived inhibitors that have been described are generally cysteine containing molecules that are related to the CAAX motif that is the signal for protein prenylation.
  • Such inhibitors may inhibit protein prenylation while serving as alternate substrates for the farnesyl-protein transferase enzyme, or may be purely competitive inhibitors (U.S. Patent 5,141 ,851 , University of Texas; N.E. Kohl et al, Science, 260: 1934-1937 (1993); Graham, et al., J. Med. Chem., 37, 725 (1994)).
  • deletion of the thiol from a CAAX derivative has been shown to dramatically reduce the inhibitory potency of the compound.
  • the thiol group has been shown to dramatically reduce the inhibitory potency of the compound.
  • the thiol group
  • the present invention comprises analogs of the CAAX motif of the protein Ras that is modified by famesylation in vivo. These CAAX analogs inhibit the famesylation of Ras. Furthermore, these CAAX analogues differ from those previously described as inhibitors of Ras famesyl transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol- dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these famesyl transferase inhibitors and methods for their production.

Abstract

L'invention porte sur des analogues du motif CAAX de la protéine Ras modifiés in vivo par farnésylation. Lesdits analogues, qui inhibent la farnésylation de la Ras, diffèrent par ailleurs de ceux précédemment décrits comme inhibiteurs de la Ras farnésyle transférase en ce qu'ils ne présentent pas de fraction thiol. Cette absence de thiol offre des avantages uniques en matière d'amélioration du comportement pharmacocinétique chez les animaux, de prévention des réactions chimiques liées aux thiols telles que la rapidité de l'auto-oxydation, la formation de bisulfures avec les thiols endogènes et une toxicité systémique réduite. L'invention porte également sur des compositions chimiothérapeutiques contenant les susdits inhibiteurs et sur leur procédé d'obtention.
