The invention pertains to novel peptide-like FPP-analogues suitable for inhibiting protein:prenyl transferases, such as protein:geranylgeranyl transferase-1, and other prenyl pyrophosphate-consuming enzymes such as squalene synthase and geranylgeranyl pyrophoshate synthase. The analogues comply with the following formula:
A-B-D (1) or A-B-B'-D(2):
A = Ap-(CH2)0-3-Z1-(CH2)0-3-(CHR1)0-1Y-
B and B' are independently -NR2-(CH2)0-3-Z2-(CH2)0-3-CHR3-Y-, or
with the proviso that B or B' contains at least 4 chain atoms,
D = -NH-CH(COX)-R4
in which:
Ap = an apolar hydrocarbon group, optionally substituted;
R1 = hydrogen, C1-4 alkyl optionally substituted with aryl or heteroaryl;
R2 = hydrogen, C1-4 alkyl optionally substituted with aryl or heteroaryl;
R3 = hydrogen, C1-4 alkyl optionally substituted with aryl, heteroaryl or amino;
R4 = C1-4 alkyl or benzyl, which is substituted with at least one acidic group;
X = OH, OM (M being an alkali metal), O-(C1-4 alkyl), NH-peptidyl or C1-3 alkyl which is substituted with a peptidomimetic group;
Y = carbonyl or methylene;
Z1 = -CH2-CHR10-, -CH=CR10-, -C≡C-, 1,2-, 1,3- or 1,4-cyclohexylene or -phenylene, -CO-, -CO-NH-, -O-CO-NH or -O-, or a direct bond;
Z2= -CH2-CHR10-, -CH=CR10-, -C≡C-, 1,2-, 1,3- or 1,4-cyclohexylene or -phenylene, -O-, -S-, -NH-, or a direct bond;
or a salt or ester thereof.
