Structure‐Activity Studies Reveal Scope for Optimisation of Ebselen‐Type Inhibition of SARS‐CoV‐2 Main Protease
摘要:
AbstractThe reactive organoselenium compound ebselen is being investigated for treatment of coronavirus disease 2019 (COVID‐19) and other diseases. We report structure‐activity studies on sulfur analogues of ebselen with the Severe Acute Respiratory Syndrome coronavirus 2 (SARS‐CoV‐2) main protease (Mpro), employing turnover and protein‐observed mass spectrometry‐based assays. The results reveal scope for optimisation of ebselen/ebselen derivative‐ mediated inhibition of Mpro, particularly with respect to improved selectivity.

efficient palladium-catalyzed carbonylative cyclization of N-substituted 2-iodobenzamides and 2-iodoanilides was investigated for the synthesis of phthalimides and benzoxazinones, respectively, by usingphenylformate as a CO source. The present catalytic protocol circumvents the use of an expensive phosphine ligand as well as solvent in the case of the phthalimidesynthesis. Moreover, mild reaction conditions
通过使用甲酸苯酯作为 CO 源,研究了一种简单有效的钯催化的 N-取代 2-碘苯甲酰胺和 2-碘苯胺的羰基化环化反应,分别用于合成邻苯二甲酰亚胺和苯并嗪酮。本催化协议在邻苯二甲酰亚胺合成的情况下避免使用昂贵的膦配体以及溶剂。此外,温和的反应条件和对各种官能团的耐受性增强了该方法的普遍适用性。

The synthesis of quinazolinone derivatives was achieved from 2-iodobenzamide derivatives and various benzylamines, allylamine, and cinnamylamine derivatives through a one-pot copper-catalyzed reaction. In this reaction, the amine component (benzylamine/allylamine/cinnamylamine) is N-arylated with 2-iodobenzamide derivatives through Ullman coupling, followed by an intramolecular C–H amidation in the

A concise route for the synthesis of indenoisoquinoline derivatives from 2-iodobenzamide and 1,3-indanedione derivatives in the presence of copper(II) chloride and cesium carbonate in acetonitrile solvent is reported. A wide variety of 2-iodobenzamide derivatives and indandiones could be used to synthesize indenoisoquinoline derivatives and other fused indenoisoquinoline in moderate to good yields
