Experimental data, except buprenorphine and naltrexone, is previously reported.29 Buprenorphine and naltrexone were experimentally designated %Emax = 0 values as both are classified as antagonists at the δ receptor.6,24 BW373U86 = (±)-4-((α-R*)-α-((2S*,5R*)-4-Allyl-2,5-dimethyl-1-piperazinyl)-3-hydroxybenzyl)-N,N-diethyl-benzamide, SIOM = 7-spiroindanyloxymorphone, (E)-BNTX = [(E)-benzylidenenaltrexone].
