NOVEL TRICYCLIC PIPERIDINYL COMPOUNDS USEFUL AS INHIBITORS OF FARNESYL-PROTEIN TRANSFERASE

摘要

Novel tricyclic compounds of formula (1.0) or a pharmaceutically acceptable salt or solvate thereof, wherein: one of a, b, c, and d represents N or NR<9>, wherein R<9> is O-, -CH3 or -(CH2)nCO2H wherein n is 1 to 3, and the remaining a, b, c and d groups represent CR<1> or CR<2>; or each of a, b, c and d is independently selected from CR<1> or CR<2>; each R<1> and each R<2> is independently selected from H, halo, -CR3, -OR<10>, -COR<10>, -SR<10>, -S(O)tR<11> (wherein t is 0, 1 or 2), -SCN, -N(R<10>)2, -NR<10>R<11>, -NO2, -OC(O)R<10>, -CO2R<10>, -OCO2R<11>, -CN, -NHC(O)R<10>, -NHSO2R<10>, -CONHR<10>, -CONHCH2CH2OH, -NR<10>COOR<11>, -SR<11>C(O)OR<11>, -SR<11>N(R<75>)<2>; n is 0 (zero), 1, 2, 3, 4, 5 or 6; T is -CO-; -SO-; -SO2-; or -CR<30>R<31>-; Z represents alkyl, aryl, aralkyl, heteroalkyl, heteroaryl, heteroarylalkyl, heterocycloalkyl, heterocycloalkylalkyl, -OR<40>, -SR<40>, -CR<40>R<42>, -NR<40>R<42>, formulae (i), (ii), (iii), (iv), (v) and (vi). Pharmaceutical compositions are disclosed which are inhibitors of the enzyme, farnesyl protein transferase. Also disclosed is a method of inhibiting Ras function and therefore inhibiting the abnormal growth of cells. The method comprises administering the novel tricyclic compound to a biological system. In particular, the method inhibits the abnormal growth of cells in a mammal such as a human.
