Definitions

  • This invention relates to compounds that inhibit farnesyl- protein transferase and ras protein farnesylation, thereby making them useful as anti-cancer agents.
  • the compounds are also useful in the treatment of diseases, other than cancer, associated with signal transduction pathways operating through ras and those associated with proteins other than ras that are also post-translationally modified by the enzyme farnesyl protein transferase.
  • the compounds may also act as inhibitors of other prenyl transferases, and thus be effective in the treatment of diseases associated with other prenyl modifications of proteins.
  • the mammalian ras gene family comprises three genes, H-ras, K-ras and N-ras.
  • the ras proteins are a family of GTP-binding and hydrolyzing proteins that regulate cell growth and differentiation. Overproduction of normal ras proteins or mutations that inhibit their GTPase activity can lead to uncontrolled cell division.
  • the transforming activity of ras is dependent on localization of the protein to plasma membranes. This membrane binding occurs via a series of post-translational modifications of the cytosolic Ras proteins. The first and mandatory step in this sequence of events is the farnesylation of these proteins.
  • the reaction is catalyzed by the enzyme farnesyl protein transferase (FPT), and farnesyl pyrophosphate (FPP) serves as the farnesyl group donor in this reaction.

  • the ras C-terminus contains a sequence motif termed a "Cys-Aaai-Aaa ⁇ / Xaa” box (CAAX box), wherein Cys is cysteine, Aaa is an aliphatic amino acid, and Xaa is a serine or methionine. Farnesylation occurs on the cysteinyl residue of the CAAX box (cys-186), thereby attaching the prenyl group on the protein via a thio-ether linkage.

The mixture was stirred for 3 h, and treated with aq. potassium carbonate. The suspension was stirred, filtered, and concentrated. The residue was dissolved in methanol, IN HCl in ether was added, solvent was removed to give title compound as a solid (22 mg). MS (M+H): 502.
  • Example 4 and ethyl glyoxalate by following the procedure for the preparation of Example 6. MS (M+H): 481.
