  X-ray Structural and Biological Evaluation of a Series of Potent and Highly Selective Inhibitors of Human Coronavirus Papain-like Proteases

  摘要：

  Structure-guided design was used to generate a series of noncovalent inhibitors with nanomolar potency against the papain-like protease (PLpro) from the SARS coronavirus (CoV). A number of inhibitors exhibit antiviral activity against SARS-CoV infected Vero E6 cells and broadened specificity toward the homologous PLP2 enzyme from the human coronavirus NL63. Selectivity and cytotoxicity studies established a more than 100-fold preference for the coronaviral enzyme over homologous human deubiquitinating enzymes (DUBs), and no significant cytotoxicity in Vero E6 and HEK293 cell lines is observed. X-ray structural analyses of inhibitor-bound crystal structures revealed subtle differences between binding modes of the initial benzodioxolane lead (15g) and the most potent analogues 3k and 3j, featuring a monofluoro substitution at para and meta positions of the benzyl ring, respectively. Finally, the less lipophilic bis(amide) 3e and methoxypyridine 5c exhibit significantly improved metabolic stability and are viable candidates for advancing to in vivo studies.

  An efficient protocol for the Cα-H heteroarylation of ethers, amides, and alcohols using air and light under mild conditions is described. The reaction is applicable to a wide spectrum of functional groups. The generation of C-radicals via photoinduced aerobic oxidation of ethers, amides, and alcohols is the key feature of the process. Control experiments suggest a radical pathway for the reaction

  major limitations of previously reported photoredox-mediated Minisci reactions: (i) use of expensive and potentially harmful non-recyclable photocatalysts, and (ii) requirement of a stoichiometric amount of strong chemical oxidant. Finally, using platinum as a co-catalyst with the carbon nitride allows this light-mediated reaction to generate two value-added products under an anaerobic atmosphere –

  据报道，在室温下，使用大气氧作为氧化剂，氰胺官能化的氮化碳粉末可作为杂芳烃与醚，醇和酰胺的直接Minisci型偶联的光催化剂。这种温和的方案显示出广泛的底物范围，良好的官能团耐受性，催化剂可以轻松分离并重复使用数个周期。因此，它解决了先前报道的光氧化还原介导的Minisci反应的两个主要局限性：（i）使用昂贵且可能有害的不可回收光催化剂，以及（ii）需要化学计量的强化学氧化剂。最后，使用铂作为氮化碳的助催化剂，可以使这种光介导的反应在厌氧气氛下产生两种增值产品：功能化杂芳烃和氢2燃料。

  The resolution of racemic 1-(2-pyridyl)ethanols 2a-n, including the 2,2'-bipyridyl and isoquinolyl derivatives, by lipase-catalyzed asymmetric acetylation with vinyl acetate is reported. The reactions were carried out in diisopropyl ether at either room temperature or 60 degrees C using Candida antarctica lipase (CAL) to give (R)-acetate and unreacted (S)-alcohol with excellent enantiomeric purities

  据报道，外消旋的1-（2-吡啶基）乙醇2a-n（包括2,2'-联吡啶基和异喹啉基衍生物）通过脂肪酶催化乙酸乙烯酯的不对称乙酰化而得到拆分。反应在室温或60℃下使用南极假丝酵母脂肪酶（CAL）在二异丙醚中进行，以良好的收率得到具有优异对映体纯度的（R）-乙酸酯和未反应的（S）-醇。对于在吡啶环的6位带有sp（3）型碳的底物，如2c，2d和2e，在室温下具有1-羟丙基和烯丙基的底物，在室温下反应速率相对较慢。吡啶环上的2位，例如2l和2m。在这种情况下，需要更高的温度。因此，当反应在60摄氏度下进行时，在不丧失高对映体特异性的情况下将其加速了3至7倍。然而，即使当在60℃下反应持续更长的时间时，均丙醇2n的反应仍未完成。该酶拆分实际上可用于从10mg至10g或从10mg至10g的较宽反应规模。更多。该催化剂可重复使用，每次使用会损失5-10％的初始活性。
• THE EFFECT OF EXTERNAL MAGNETIC FIELD ON THE PHOTOINDUCED SUBSTITUTION REACTION OF 1-ISOQUINOLINECARBONITRILE
  作者：Norisuke Hata、Yukio Yamada

  DOI：10.1246/cl.1980.989

  日期：1980.8.5

  The photosubstitution reaction of 1-isoquinolinecarbonitrile in ethanol was found to be subject to a magnetic field effect due to the Δg mechanism. The result suggests that the reaction proceeds predominantly via the formation of triplet radical pair subsequent to hydrogen abstraction by the triplet nitrile from the solvent, although it does not exclude the singlet reaction pathway.

  由于 Δg 机制，发现 1-异喹啉甲腈在乙醇中的光取代反应受到磁场效应的影响。结果表明，该反应主要通过三线态腈从溶剂中夺氢后形成三线态自由基对进行，尽管它不排除单线态反应途径。
