anti-9-amino-6-(trifluoromethyl) benzonorbornene (19), were prepared and evaluated. The competitive inhibition displayed by the fully extended analogue 12 coupled with the uncompetitive kinetics exhibited by the folded isomer 13 supports previous findings that a fully extended side chain conformation is optimal for binding to the active site of PNMT. In addition, the fact that 12 displayed enhanced affinity as an
