A new type of kappa-agonist, 17-cyclopropylmethyl-3, 14 beta-dihydroxy-4,5 alpha-epoxy-6 beta-[N-methyl-trans-3-(3-furyl) acrylamido]morphinan hydrochloride (1, TRK-820), was discovered by a new working hypothesis. The "message-address concept" for opioid antagonists and the "accessory site" for general antagonists were applied to design TRK-820. A
