• Bioisosteric Replacement and Related Analogs in the Design, Synthesis and Evaluation of Ligands for Muscarinic Acetylcholine Receptors
  作者：Richie Bhandare、Daniel Canney

  DOI：10.2174/15734064113096660043

  日期：2014.4

  Previous structure-activity relationship studies involving a series of lactone-based muscarinic ligands identified a lead compound containing a diphenylmethylpiperazine moiety (4; IC50 = 340 nM). The purpose of the present work is to investigate 1,3-benzodioxoles, 4,4-diethyl substituted tetrahydrofurans, 5-substituted oxazolidinones and chromones as bioisosteric replacements for the lactone ring in a novel series of muscarinic ligands. The approach provided compounds with improved % inhibition values and identified a non-selective muscarinic ligand with an IC50 value of 280 nM. The structure-activity relationship for this new series will be discussed. Selected compounds were evaluated in preliminary assays for subtype selectivity and were found to be non-selective.

  之前关于一系列基于内酯的毒蕈碱配体的结构-活性关系研究中，确定了一种含有二苯甲基哌嗪基团的领先化合物（4；IC50 = 340 nM）。本研究的目的是探讨1,3-苯并二氧杂环、4,4-二乙基取代的四氢呋喃、5-取代的噁唑烷酮和色烯作为新系列毒蕈碱配体中内酯环的生物等效替代物。该方法提供了具有改善的抑制率值的化合物，并识别出一种非选择性的毒蕈碱配体，其IC50值为280 nM。将讨论这一新系列的结构-活性关系。选定的化合物在初步实验中进行亚型选择性评估，结果发现它们是非选择性的。

  DOI：10.1039/d1cc02493k

  日期：——

  base-promoted switchable synthesis of five- and six-membered cyclic carbamates using atmospheric pressure carbon dioxide as the C1 source was developed. The chemoselectivity of products was simply controlled by changing bases and solvents. The reaction proceeds effectively under mild conditions, affording valuable cyclic carbamates. Experimental results and DFT studies revealed the reaction mechanism.
