Description

ANΗ-INFLAMMATORY MEDICAMENT CONTAINING FARNESYL PROTEIN TRANSFERASE INHIBITOR, ITS PREPARATION AND USE
BACKGROUND
The enzyme farnesyl protein transferase (EC 2 5 1 p21 AS farnesyl transferase, FPTase) is a key component in the post-translational processing of a number of cellular proteins It catalyses the reaction between farnesyl pyrophosphate and proteins which have as their C-terminal sequence a "CaaX" motif (where C is cysteine, a is an aliphatic amino-acid and X is one of a number of amino-acids including seπne, methionine and glutamine) The outcome of the reaction is the formation of a thioether in which the farnesyl unit is covalently linked to the cysteine sulphur atom (Scheme 1)
Figure imgf000003_0001
Farnesyl pyrophosphate "CaaX" protein
FPTase
Figure imgf000003_0002
Amongst the most widely investigated families of protein substrates for FPTase are the products of the ras genes, p21ra\ including Kirsten (K-)ras, Harvey (Ha-)ras and N-ras as proteins are GTPases that control a number of intracellular signal transduction cascades In order to function correctly, the ras proteins need to be localised at a cell membrane The presence of a lipophihc farnesyl group at the C-terminus is a key determinant for effective translocation from the cytosol to the membrane, so inhibition of FPTase can result in failure of the protein to localise correctly and hence can lead to blockade of the downstream signals i A number of groups have found inhibitors of FPTase. The compounds that have been reported are structurally diverse. Many are analogues of the "CaaX" motif, a smaller number are analogues of farnesyl pyrophosphate or of the two substrates together, and a few have no obvious structural relationship to either substrate. Representative examples are illustrated in the figures below.

The utility of these compounds has been studied particularly in the area of anti-cancer therapy Ras mutations are prevalent in a number of tumours, and they are presumed to have a role in the etiology of the disease in these cases FPTase inhibitors have been tried in animal models of cancer with good results Experimental tumours regress dunng treatment and do not recur until the drug is withdrawn Importantly, no drug toxicity is seen even after prolonged treatment In consequence, it has been suggested that FPTase inhibitors have no effect on "normal" tissue (I e tissue that does not express mutant activated ras) We have now found evidence that inhibitors of FPTase do have an effect on T lymphocytes which have no ras mutations This unexpected finding suggests a new therapeutic role for FPTase inhibitors in the management of pathophysiological conditions in which there is involvement of T lymphocytes These will typically be diseases which are characteπsed by an immunoinflammatory component, and include, for example, inflammatory bowel disease (ulcerative colitis and Crohn's disease), asthma and rheumatoid arthntis
