Abstract
Piperazinyl benzamidines were prepared and found to bind to the rat delta ( delta) opioid receptor. The most active compounds had a N,N-diethylcarboxam ido group and N-benzyl piperazine. The most potent among these was N,N-diet hyl-4-[4-(phenylmethyl)-1 -piperazinyl][2-(trifluoromethyl)phenyl]iminometh yl]benzamide (27) with a 1.22 nM K-i for the rat delta opioid receptor and ca. 1000x selectivity relative to the mu opioid subtype.
