    Lead Optimization of a Novel Series of Imidazo[1,2-a]pyridine Amides Leading to a Clinical Candidate (Q203) as a Multi- and Extensively-Drug-Resistant Anti-tuberculosis Agent
    摘要:
    A critical unmet clinical need to combat the global tuberculosis epidemic is the development of potent agents capable of reducing the time of multi-drug-resistant (MDR) and extensively-drug-resistant (XDR) tuberculosis therapy. In this paper, we report on the optimization of imidazo[1,2-a]pyridine amide (IPA) lead compound 1, which led to the design and synthesis of Q203 (50). We found that the amide linker with IPA core is very important for activity against Mycobacterium tuberculosis H37Rv. Linearity and lipophilicity of the amine part in the IPA series play a critical role in improving in vitro and in vivo efficacy and pharmacokinetic profile. The optimized IPAs 49 and 50 showed not only excellent oral bioavailability (80.2% and 90.7%, respectively) with high exposure of the area under curve (AUC) but also displayed significant colony-forming unit (CFU) reduction (1.52 and 3.13 log10 reduction at 10 mg/kg dosing level, respectively) in mouse lung.

    摘要:
    光化学反应已成为有机化学家的重要工具。可见(太阳能)光可以方便地采用,但是,只有在使用有色有机化合物时或在吸收可见光的光催化剂引起的光催化过程中,才可以使用可见光。本文中,我们证明了光不稳定的,有色的部分可以掺入无色有机化合物中,目的是在暴露于可见(太阳能)光下产生高反应性的中间体。芳基重氮盐的有色热稳定衍生物芳基偶氮砜被用作有价值的底物,用于不需要(光)催化剂或其他添加剂来促进反应的(杂)联芳基的光诱导无金属合成。值得注意的是

  • Metal-Free, Visible-Light-Mediated Direct C–H Arylation of Heteroarenes with Aryl Diazonium Salts
    作者:Durga Prasad Hari、Peter Schroll、Burkhard König
    DOI:10.1021/ja212099r
    日期:2012.2.15
    Visible light along with 1 mol % eosin Y catalyzes the direct C-H bond arylation of heteroarenes with aryl diazonium salts by a photoredox process. We have investigated the scope of the reaction for several aryl diazonium salts and heteroarenes. The general and easy procedure provides a transition-metal-free alternative for the formation of aryl-heteroaryl bonds.

    irradiation in the presence of catalytic amounts of [(DPEphos)(bcp)Cu]PF6 and an amine, a range of unactivated aryl and alkyl halides were shown to be smoothly activated through a rare Cu(I)/Cu(I)*/Cu(0) catalytic cycle. This complex efficiently catalyzes a series of radical processes, including reductions, cyclizations, and direct arylation of arenes.

    quantitative bidirectional isomerization. Additionally, extending conjugation from the electron-rich pyrrole results in quantitative visible-light photoswitches, as well as photoswitches that isomerize with red and near-infrared light. The presence of the hydrogen bond leading to the observed redshift is supported by computational and spectroscopic evidence.

  • C–H arylation reactions through aniline activation catalysed by a PANI-g-C<sub>3</sub>N<sub>4</sub>-TiO<sub>2</sub> composite under visible light in aqueous medium

    DOI:10.1039/c8gc00012c
    日期:——
    composite was prepared and found to be efficient for radical C–H arylation reactions. The arylation process involved coupling of in situ generated aryl diazonium salts from aniline with heteroarenes, enol acetates or benzoquinones under visible light in aqueous medium or pure water. A broad range of substrates survived the reaction conditions to provide the desired products in moderate to good yields

    available catalysts based on inexpensive, environmentally benign base metals are therefore strongly needed. Furthermore, expanding the toolbox of methods based on photoredox catalysis will facilitate the discovery of new light-mediated transformations. This article details the use of a simple copper complex which, upon activation with blue light, can initiate a broad range of radical reactions.
    有机转化大致可分为四类,包括阳离子反应、阴离子反应、周环反应和自由基反应。尽管几十年来人们都知道最后一类可以提供非常有效的合成途径,但它长期以来一直受到有毒试剂需求的阻碍,这在很大程度上限制了它对化学合成的影响。随着产生自由基物质的新概念的引入,这种情况已经结束,光氧化还原催化——它仅依赖于使用可在可见光照射下激活的催化剂——当然是最有效的一种。最先进的催化剂主要依赖于钌和铱络合物以及有机染料的使用,这仍然在很大程度上限制了它们在化学过程中的广泛应用:因此,迫切需要基于廉价、环境友好的贱金属的替代现成催化剂。此外,扩展基于光氧化还原催化的方法工具箱将有助于发现新的光介导转化。本文详细介绍了简单的铜络合物的使用,该络合物在蓝光激活后可以引发广泛的自由基反应。
