  azide-alkyne cycloaddition (CuAAC) click reactions. Through chemical proteomics, putatively hybrid-binding protein targets of the ART-quinolines were successfully identified in addition to known targets of quinoline and artemisinin alone, suggesting that the hybrids act through multiple modes of action to overcome resistance.

  世界范围内的一个重大挑战是疟疾寄生虫对氯喹 (CQ) 等批准药物的紧急耐药性。为了解决这些未解决的 CQ 抗性问题，仅报道了基于青蒿素 (ART) 的杂种的罕见例子。此外，尚未确定此类杂交体的蛋白质靶标，这些杂交体具有优异功效的原因尚不清楚。在此，我们报告了新型 ART-异喹啉和 ART-喹啉杂种的合成，显示出对 CQ 抗性和多重抗药性恶性疟原虫菌株（EC50 (Dd2) 低至 1.0 nm；EC50 (K1) 低至 0.78 nm）的高度改进效力) 与 CQ (EC50 (Dd2)=165.3 nm；EC50 (K1)=302.8 nm) 相比，并且在实验性疟疾中强烈抑制寄生虫血症。这些新化合物可以通过逐步经济的 CH 活化和铜 (I) 催化的叠氮化物-炔环加成 (CuAAC) 点击反应轻松获得。通过化学蛋白质组学，除了已知的喹啉和青蒿素单独靶标外，还成功鉴定了 ART-喹啉的假定杂交结

The aim of this study is to find a potential agent not only on the treatment of cancer, but also for reducing CRF level of cancer patients. In this study, total-thirty new Dihydroartemisinin–Coumarin hybrids (DCH) were designed and synthesized. The in vitro cytotoxicity against cancer cell lines (HT-29, MDA-MB-231, HCT-116, and A549)

  癌症患者经常患有癌症相关疲劳 (CRF)，这是一种与虚弱和情绪低落相关的复杂综合征。神经炎症是 CRF 的主要诱因之一。本研究的目的是寻找一种潜在的药物，不仅可以治疗癌症，还可以降低癌症患者的 CRF 水平。在这项研究中，总共设计并合成了 30 种新的双氢青蒿素-香豆素杂化物（DCH）。评估了对癌细胞系（HT-29、MDA-MB-231、HCT-116 和 A549）的体外细胞毒性。同时，我们还测试了 DCH 的抗神经炎症活性。DCH 可以抑制激活的小胶质细胞 N9 释放 NO、TNF-α 和 IL-6。对接分析表明，TLR4的共同受体MD-2可能是DCH的靶点之一。

  recently been discovered as a Toll-like Receptor 4 (TLR4) antagonist. However, the TLR4 antagonistic activity of DHA is modest and it exhibits cellular toxicity. In this work, the structure-activity relationship (SAR) of DHA as TLR4 antagonist was explored. Since destroying the sesquiterpene endoperoxide scaffold substantially compromised the TLR4 antagonistic activity and molecular dynamics analysis

  双氢青蒿素(DHA)，一种从传统中草药青蒿中分离出来的天然产物作为一种抗疟疾感染的临床一线药物，最近被发现是一种 Toll 样受体 4 (TLR4) 拮抗剂。然而，DHA 的 TLR4 拮抗活性是适度的，并且表现出细胞毒性。在这项工作中，探索了 DHA 作为 TLR4 拮抗剂的构效关系 (SAR)。由于破坏倍半萜内过氧化物支架显着损害了 TLR4 拮抗活性，分子动力学分析表明 C-10 羟基与髓细胞分化因子 2 (MD2) 的 E72 形成氢键以防止其深入 MD2，因此 DHA 的 SAR 为专注于 C-10 半缩醛位置。随着在 C10 位置延长直链烷烃链的长度，DHA 类似物的 TLR4 拮抗活性先增加后降低，最好的 TLR4 拮抗作用发生在 3-4 个碳的碳链长度处。相比之下，DHA 类似物的细胞毒性随着线性烷烃链长度的增加而增加。以取代卤素为末端官能团的DHA衍生物的TLR4拮抗活性

  To develop novel agents with anticancer activities, thirty-four new dihydroartemisinin-coumarin hybrids were designed and synthesized in this study. Those compounds were identified that had great anticancer activity against two cancer cell lines (MDA-MB-231 and HT-29). The structure-activity relationships of the derivatives were also discussed, and the results of docking analysis had shown that carbonic anhydrases IX (CA IX) was very likely to be one of the drug targets of the hybrids. Meanwhile, to clarify the mechanism of the anticancer activity of the hybrids molecule, we did further exploration in the bioactivity of the hybrids. The results had shown that these derivatives obviously inhibited proliferation of HT-29 cell lines, arrested G(0)/G(1) phase of HT-29 cells, suppressed the migration of tumor cells, and induced a great decrease in mitochondrial membrane potential leading to apoptosis of cancer cells. Interestingly, the hybrids also induced the other cell death pathway-ferroptosis. (C) 2018 Elsevier Masson SAS. All rights reserved.
