Synthesis of alkyne-linked glycoamino acids via ring-closing alkyne metathesis is investigated. Two different strategies are described to attach alkynylamino acids to an alkynyl sugar, either via a linker at O-4 or at O-9 of the alkynyl sugar. Ring-closing alkyne metathesis of the O-4 linked diynes failed to proceed, but alkyne-linked glycoamino acids of different chain length were effectively synthesized via attachment at O-9.
The present invention is directed to compounds which inhibit farnesyl-protein transferase (FTase) and the farnesylation of the oncogene protein Ras. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for inhibiting farnesyl-protein transferase and the farnesylation of the oncogene protein Ras.
The present invention has as its object providing phenethylamine derivatives that typically function as a motilin receptor antagonist and which are useful as medicines. The invention provides compounds represented by the general formula (1):
(wherein A is typically an amino acid residue, R1 is typically R6—CO—, R2 is typically a hydrogen atom, R3 is typically —CO—R7, R4 is typically an alkyl group, R5 is typically a hydroxyl group, R6 is typically an alkyl group, and R7 is typically an amino group).
