Conversion of the potent δ-opioid agonist H-Dmt-Tic-NH-CH 2-Bid into δ-opioid antagonists by N1-benzimidazole alkylation

N1-Alkylation of 1H-benzimidizole of the δ agonist H-Dmt-Tic-NH-CH2-Bid with hydrophobic, aromatic, olefinic, acid, ethyl ester, or amide (1-6) became δ antagonists (pA2 = 8.52-10.14). δ- and μ-Opioid receptor affinities w
