Publication Abstract from PubMed
Benzocycloheptapyridine tricyclic compounds with piperazine or substituted piperidine moieties extending either from the 5- or 6-position of the tricyclic bridgehead exhibited enhanced FTase activity: this resulted from favorable binding of the ligand nitrogen with the catalytic zinc found in the FTase. A single isomer at C-11 with piperazine adduct extending from the 6-position, compound 24, exhibited excellent FTase activity with IC50 = 0.007 microM, soft agar IC50 = 72 nM, and Rat AUC(PO, 10 mpk) = 4.0 microM x h. X-ray of (-)-[8-chloro-6-(1-piperazinyl)-1H-benzo[5,6]]cyclohepta[1,2-b]pyridine-11 -yl]-1-(methylsulfonyl)piperidine 24 bound to Ftase revealed favorable interaction between piperazine nitrogen and catalytic zinc atom.
