  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.

  Derivatives of N,N-diethyl-N'- phenyl-piperazine, a silent agonist of the mammalian α7 nicotinic acetylcholine receptor, are provided. These silent agonists control the desensitization state of the receptor. Further provided are pharmaceutical compositions that allow the administration of the silent agonists of the disclosure to a subject animal or human in need of treatment for a pathological condition arising from such as inflammation. The novel silent agonists also may be co-administered to a patient simultaneously or consecutively with a type II positive allosteric modulator to modulate the activity of the receptor.
