The invention features a compound of the formula W-Y-Q-Z or W-Y-Z wherein W is a farnesyl group, a geranylgeranyl group, a substituted farnesyl group or a substituted geranylgeranyl group; ##STR1## wherein n=1, 2, 3, 4, 5, or 6; each of T.sub.1' . . . T.sub.n' and T.sub.1" . . . T.sub.n" is independently: Fl, Br, --NHCOCH.sub.3, --NH.sub.2, a peptide, an alkane group, an alkene group, an polyethyleneglycol group, a saturated fatty acid, an unsaturated fatty acid, a monosaccharide, or a disaccharide; and Z is --COOH or salts or esters thereof, --CONH.sub.2, --NO.sub.2, --PO.sub.3 or salts or esters thereof, --C N, or --SO.sub.3 or salts or esters thereof, provided that when W is farnesyl, Y is --S--, n=2, and either T.sub.2' or T.sub.2" is --NHCOCH.sub.3, then Z is not --COOH. The compounds of the invention are capable of interfering with enzymatic methylation of a peptide having the carboxyl-terminal motif --CAAX wherein C=cysteine, A=aliphatic amino acid, and X=any amino acid.
该发明涉及一种化合物,其化学式为W-Y-Q-Z或W-Y-Z,其中W为顺式异戊烯基、长链异戊烯基、取代顺式异戊烯基或取代长链异戊烯基;Y为-(CH2)n-,其中n=1、2、3、4、5或6;T1'...Tn'和T1"...Tn"各自独立地为Fl、Br、-NHCOCH3、-NH2、肽、烷基、烯基、聚乙二醇基、饱和脂肪酸、不饱和脂肪酸、单糖或双糖;Z为-COOH或其盐或酯、-CONH2、-NO2、-PO3或其盐或酯、-CN或-SO3或其盐或酯,但当W为顺式异戊烯基时,Y为-S-,n=2,并且T2'或T2"为-NHCOCH3时,则Z不为-COOH。该发明的化合物能够干扰具有羧基末端基序列-CAAX(其中C=半胱氨酸,A=脂肪族氨基酸,X=任何氨基酸)的肽的酶促甲基化。
