title: Synthesis of 5,6-dihydro-11H-benzo[5,6]-cyclohepta[1,2-b]pyridin-11-ylidene)-1-piperidine-N-cyanoguanidine derivatives as inhibitors of ras farnesyl protein transferase.
abstract: A series of novel N-cyanoguanidine tricyclic farnesyl protein transferase (FPT) inhibitors was prepared. Replacement of a piperidine amide-group with a N-cyanoguanidine functionality increased FPT activity. X-ray crystal structure determination of 42 complexed with FPT revealed differences in the interactions of the amide and N-cyanoguanidine groups with the protein.
