Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 143 words
A compound which inhibits farnesyl - protein transferase of the formula: wherein: X or Y   are independently H₂ or O, provided that at least one of these is H₂; R¹ is   H, an alkyl group, an acyl group, an alkylsulfonyl group or arylsulfonyl group, wherein alkyl and acyl groups comprise straight chain or branched chain hydrocarbons of 1 to 6 carbon atoms, or in the alternative R¹NH may be absent; R² and R³   are the side chains of naturally occurring amino acids, or in the alternative may be substituted or unsubstituted aliphatic, aromatic or heterocyclic groups, such as allyl, cyclohexyl, phenyl, pyridyl, imidazolyl or saturated chains of 2 to 8 carbon atoms, wherein the aliphatic substitutents may be substituted with an aromatic or heteroaromatic ring; Z is   O or S; and n is   0, 1, or 2; or the pharmaceutically acceptable salts thereof.
Claim 2
Dependent Claim 142 words
A compound which inhibits farnesyl-protein transferase of the formula: wherein: X or Y   are independently H₂ or O, provided that at least one of these is H₂; R¹ is   H, an alkyl group, an acyl group, an alkylsulfonyl group or arylsulfonyl group, wherein alkyl and acyl groups comprise straight chain or branched chain hydrocarbons of 1 to 6 carbon atoms, or in the alternative R¹NH may be absent; R² and R³   are the side chains of naturally occurring amino acids, or in the alternative may be substituted or unsubstituted aliphatic, aromatic or heterocyclic groups, such as allyl, cyclohexyl, phenyl, pyridyl, imidazolyl or saturated chains of 2 to 8 carbon atoms, wherein the aliphatic substitutuents may also be substituted with an aromatic or heteroaromatic ring; Z is   O or S; and n is   0, 1, or 2; or the pharmaceutically acceptable salts thereof.
