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 NR9 wherein R9 is O-, -CH3 or -(CH2)nCO2H wherein n is 1 to 3, and the remaining a, b, c and d groups represent CR1 or CR2; or each of a, b, c, and d are independently selected from CR1 or CR2; each R1 and each R2 is independently selected from H, halo, -CF3, -OR10, -COR10, -SR10, -S(O)tR11 (wherein t is 0, 1 or 2), -SCN, -N(R10)2, -NR10R11, -NO2, -OC(O)R10, -CO2R10, -OCO2R11, -CN, - NHC(O)R10, -NHSO2R10, -CONHR10, -CONHCH2CH2OH, -NR10COOR11, -SR11C(O)OR11, - SR11N(R75)2; y is 0 (zero) or 1; n is 0, 1, 2, 3, 4, 5 or 6; T is -CO-; -SO-; - SO2-; or -CR30R31; Z represents alkyl, aryl, aralkyl, heteroalkyl, heteroaryl, heteroarylalkyl, heterocycloalkyl, heterocycloalkylalkyl, -OR40, -SR40, 1C- R40R42, (i), (ii), -NR40R42, (iii). 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.

L'invention porte sur de nouveaux composés tricycliques de formule (1.0) ou leur sels ou solvates pharmacocompatibles dans laquelle: l'un de a, b, c ou d représente N ou NR?9¿ où R?9¿ est O?-¿, -CH¿3? ou -(CH¿2?)¿n?CO¿2?H où n est 1 à 3, et les groupes a, b, c et d restants représentent CR?1¿ ou CR?2¿; ou bien chacun de a, b, c et d est sélectionné indépendamment parmi CR?1¿ ou CR?2¿; chaque R?1¿ et chaque R?2¿ est sélectionné indépendamment parmi H, halo, -CF¿3?, -OR?10¿, -COR?10¿, SR?10¿, -S(O)¿t?R?11¿ (où t est 0, 1 ou 2), -SCN, -N(R?10¿)¿2?, -NR?10¿R?11¿, -NO¿2?, -OC(O)R?10¿, -CO¿2?R?10¿, -OCO¿2?R?11¿, -CN, -NHC(O)R?10¿, -NHSO¿2?R?10¿, -CONHR?10¿, -CONHCH¿2?CH¿2?OH, -NR?10¿COOR?11¿, -SR?11¿C(O)OR?11¿, -SR?11¿N(R?75¿)¿2?; y est zéro ou 1; n est zéro, 1, 2, 3, 4, 5 ou 6; T est -CO-, -SO-, -SO¿2?- ou -CR?30¿R?31¿-; Z représente alkyle, aryle, aralkyle, hétéroalkyle, hétéroaryle, hétéroarylalkyle, hétérocycloalkyle, hétérocycloalkylalkyle, -OR?40¿, -SR?40¿, -CR?40¿R?42¿, la formule (i), la formule (ii), -NR?40¿R?42¿ ou la formule (iii). L'invention porte également sur des compositions pharmaceutiques inhibitrices de la farnésyl-protéine transférase et sur un procédé d'inhibition de la fonction Ras et par là de la croissance anormale des cellules, consistant à administrer les nouveaux composés tricycliques à un système biologique. Lesdits procédés inhibent en particulier la croissance anormale des cellules, en particulier chez des mammifères tels que l'homme.
