  Dissection of N,N-diethyl-N′-phenylpiperazines as α7 nicotinic receptor silent agonists

  摘要：

  The alpha 7 nicotinic acetylcholine receptor (nAChR) is a target for control of inflammation-related phenomena via compounds that are able to selectively induce desensitized states of the receptor. Compounds that selectively desensitize, without facilitating significant channel activation, are termed 'silent agonists' because they can be discriminated from antagonists by the currents evoked with co-application with type II positive allosteric modulators (PAMs). One example is N, N-diethyl-N'-phenyl-piperazine(diEPP) (J. Pharm. Exp. Ther. 2014, 350, 665). We used Ullmann-type aryl amination to synthesize a panel of 27 compounds related to diEPP by substitutions at the aryl ring and in the linkage between the piperazine and phenyl rings. Two-electrode voltage clamping of the human a7 nAChR expressed in Xenopus oocytes revealed that it was possible to tune the behavior of compounds to show enhanced desensitization without corresponding partial agonist activity such that trifluoromethyl and carboxamide aryl substituents showed 33 to 46-fold larger PAM-dependent net-charge responses, indicating selective partitioning of the ligand receptor complexes into the desensitized state.
