Definitions

  • Ras proteins are 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.
  • 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 must be localized to the plasma membrane for both normal and oncogenic functions. At least 3 post-translational modifications are involved with Ras membrane localization, and all 3 modifications occur at the C-terminus of Ras.
  • the 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 C15 or C20 isoprenoid, respectively.
  • the Ras protein is one of several proteins that are known to undergo post-translational farnesyl- ation.
  • 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 stmcture and function in addition to those listed above.
  • FPTase farnesyl-protein transferase
  • FPP farnesyl diphosphate
  • Ras protein substrates
  • Bisubstrate inhibitors and inhibitors of farnesyl-protein transferase that are non-competitive with the substrates have also been described.
  • 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.
  • CAAX derivative has been shown to dramatically reduce the inhibitory potency of the compound.
  • the thiol group potentially places limitations on the therapeutic application of FPTase inhibitors with respect to pharmacokinetics, pharmacodynamics and toxicity.
  • transferase inhibitors are inhibitors of proliferation of vascular smooth muscle cells and are therefore useful in the prevention and therapy of arteriosclerosis and diabetic disturbance of blood vessels (JP H7-1 12930).
  • the present invention comprises novel biaryl-containing compounds which inhibit the farnesyl-protein transferase. Further contained in this invention are chemotherapeutic compositions
