  Evaluation of N-substitution in 6,7-benzomorphan compounds

  摘要：

  6,7-Benzomorphan derivatives, exhibiting different mu, delta, and kappa receptor selectivity profiles depending on the N-substituent, represent a useful skeleton for the synthesis of new and better analgesic agents. In this work, an aromatic ring and/or alkyl residues have been used with an N-propanamide or N-acetamide spacer for the synthesis of a new series of 5,9-dimethyl-2'-hydroxy-6,7-benzomorphan derivatives (12-22). Data obtained by competition binding assays showed that the mu opioid receptor seems to prefer an interaction with the 6,7-benzomorphan ligands having an N-substituent with a propanamide spacer and less hindered amide. Highly stringent features are required for delta receptor interaction, while an N-acetamide spacer and/or bulkier amide could preferentially lead to kappa receptor selectivity. In the propanamide series, compound 12 (named LP1) displayed high mu affinity (K(i) = 0.83 nM), good delta affinity (K(i) = 29 nM) and low affinity for the kappa receptor (K(i) = 110 nM), with a selectivity ratio delta/mu and kappa/mu of 35.1 and 132.5, respectively. Further, in the adenylyl cyclase assay, LP1 displayed a mu/delta agonist profile, with IC(50) values of 4.8 and 12 nM at the mu and delta receptors, respectively. The antinociceptive potency of LP1 in the tail-flick test after sc administration in rat was comparable with the potency of morphine (ED(50) = 2.03 and 2.7 mg/kg, respectively), and was totally reversed by naloxone. LP1, possessing a mu/delta agonist profile, could represent a lead in further developing benzomorphan-based ligands with potent in vivo analgesic activity and a reduced tendency to induce side effects.

  日期：——

  For the first time, we synthesized three types of cationic linear N-chloramines that do not use the popular 5,5-dimethyl hydantoin scaffold. The characterized N-chloramines displayed satisfactory bactericidal activity, and the long-chain analogues exerted greatly elevated biocidal efficacy due to “synergistic” antibacterial actions between the N–Cl moiety and long chain cationic center. Our study provides

  我们首次合成了三种类型的阳离子线性N-氯胺，不使用流行的 5,5-二甲基乙内酰脲支架。所表征的N-氯胺表现出令人满意的杀菌活性，而长链类似物由于N-Cl部分和长链阳离子中心之间的“协同”抗菌作用而大大提高了杀菌效果。我们的研究提供了高效的杀菌剂，并为生产排除有毒氰化物盐的新型N -氯胺铺平了道路。
