  Optimization of 3-(phenylthio)quinolinium compounds against opportunistic fungal pathogens

  摘要：

  Ring-opened benzothieno[3,2-b]quinolinium salts (3) were designed and synthesized with substitution on the thiophene moiety. In vitro screenings were carried out against fungal pathogens including Cryptococcus neoformans, Candida albicans, Candida glabrata, Candida krusei and Aspergillus fumigatus. In all, by replacing the N-methyl group (2) with N-omega-phenylpentyl or omega-cyclohexylpentyl group to form substituted 3-(phenylthio)quinolinium compounds produced remarkable potencies, as high as 300-fold (cf. cryptolepine (1) = 250 mu g/mL vs lip = 0.8 mu g/mL for C. albicans) over the starting tetracyclic parent. In addition, all the N-omega-cyclohexylpentyl analogs produced superior activity against all the microorganisms tested than the N-omega-phenylpentyl substituted compounds. The potential of these compounds to induce toxicity in Vero cells was also investigated and the majority of them showed lower or no cytotoxicity at 10 mu g/mL than amphotericin B. the gold standard in antifungal drug development. For instance, the trifluoromethyl substituted analogs (11n-p) have selectivity indices over 2-fold better than those of amphotericin B in C. neoformans. Overall, this ring-opened scafford of benzothienoquinolines, with substitution on the thiophenyl moiety, serves as a new lead for further development. Published by Elsevier Masson SAS.

  Transition‐metal‐catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition‐metal‐catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated reaction temperature. Herein, we report the first examples of nickel‐catalyzed electrochemical thiolation of aryl bromides and chlorides in the absence

  过渡金属催化的偶联反应是合成芳基硫化合物的有用工具。但是，常规的过渡金属催化的芳基溴化物和氯化物的硫醇化反应通常需要在升高的反应温度下使用强碱。在此，我们报道了在室温下使用不分隔的电化学电池，在不存在外部碱的情况下，镍催化的芳基溴化物和氯化物的电化学催化硫醇化反应的第一个实例。

  involves two sequential reactions in a single pot where the formation of the iodinated heteroarene is followed by a transition-metal-free C–S coupling reaction. A wide range of heteroarene and thiol partners (including aliphatic thiols) have been used for the synthesis of thioethers. NMR studies and DFT calculations revealed the presence of a halogen bond between the thiolate anion (halogen bond acceptor)

  在可见光存在下，在室温下以单锅方式开发了一种直接从杂芳烃直接合成硫醚的有效方法。该方法涉及在一个罐中进行两个顺序的反应，在该反应中，形成碘化杂芳烃，然后进行无过渡金属的CS偶联反应。广泛的杂芳烃和硫醇伙伴（包括脂肪族硫醇）已用于合成硫醚。NMR研究和DFT计算表明，硫醇盐阴离子（卤素键受体）和碘杂芳烃（卤素键供体）之间存在卤素键。在光激发下，这种卤素键合的配合物有助于在室温下将电子从硫醇根阴离子转移到碘杂芳烃。
