nAChR antagonists. Triazoles bearing quaternary tropanes and aromatic groups were most potent for α7 nAChRs. Pharmacologicalcharacterization of the in situ reaction products established that click-chemistry synthesis with surrogate receptor templates offered novel extensions of fragment-based drug design that were applicable to multisubunit ion channels.

simple and convenient one-pot synthesis of aryl alkyl ethers by the alkoxylation of arylhalides with alcohol in the presence of Triton B as a base is described. The procedure is applicable for a variety of aryl and heteroarylhalides, and yields are very good. The use of a nonmetallic base and solvent-free conditions are important features of the reaction.
描述了在 Triton B 作为碱的存在下,通过芳基卤化物与醇的烷氧基化,简单方便地一锅法合成芳基烷基醚。该方法适用于多种芳基和杂芳基卤化物,收率非常好。使用非金属碱和无溶剂条件是反应的重要特征。

candidate nAChR ligands. The crystalstructure of one of the in situ-formed triazole-AChBP complexes shows binding poses and molecular determinants of interactions predicted from structures of known agonists and antagonists. Hence, the click chemistry approach with an in situ template of a receptor provides a novel synthetic avenue for generating candidate agonists and antagonists for ligand-gated ion channels
