  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.

  Disclosed herein are 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives, a preparation method thereof, and a therapeutic agent for treating inflammatory diseases induced by SPC, which contains the derivative as an active ingredient. The anti-inflammatory effect of the 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives was analyzed through a test employing human dermal cells and an animal test using mice and, as a result, it was found that the derivatives showed excellent inhibitory activity on SPC receptor compared to thiazole derivatives known in the prior art. Thus, the 2,4-disubstituted-5-aminocarbonyl-1,3-thiazole derivatives or pharmaceutically acceptable salts thereof are useful as active ingredients in therapeutic agents for treating inflammatory diseases, such as inflammation, pruritus and skin infection, which appear in atopic dermatitis and other diseases induced by SPC activity. wherein R 1 , R 2 , R 3 and R 4 are as defined in the specification.
