  Reinvestigating Old Pharmacophores: Are 4-Aminoquinolines and Tetraoxanes Potential Two-Stage Antimalarials?

  摘要：

  The syntheses and antiplasmodial activities of various substituted aminoquinolines coupled to an adamantane carrier are described. The compounds exhibited pronounced in vitro and in vivo activity against Plasmodium berghei in the Thompson test. Tethering a fluorine atom to the aminoquinoline C(3) position afforded fluoroaminoquinolines that act as intrahepatocytic parasite inhibitors, with compound 25 having an IC50 = 0.31 mu M and reducing the liver load in mice by up to 92% at 80 mg/kg dose. Screening our peroxides as inhibitors of liver stage infection revealed that the tetraoxane pharmacophore itself is also an excellent liver stage P. berghei inhibitor (78: IC50 = 0.33 mu M). Up to 91% reduction of the parasite liver load in mice was achieved at 100 mg/kg. Examination of tetraoxane 78 against the transgenic 3D7 strain expressing luciferase under a gametocyte-specific promoter revealed its activity against stage IV-V Plasmodium falciparum gametocytes (IC50 = 1.16 +/- 0.37 mu M). To the best of our knowledge, compounds 25 and 78 are the first examples of either an 4-aminoquinoline or a tetraoxane liver stage inhibitors.

  荧光香豆素-苯并[ b ]噻吩1，1-二氧化物缀合物作为靶向线粒体的抗肿瘤STAT3抑制剂的发现

  摘要：

  STAT3已被广泛研究为潜在的抗肿瘤靶标。尽管关于调节STAT3的研究主要集中在抑制Tyr705残基上的STAT3磷酸化，但是STAT3蛋白的Ser727残基上的磷酸化也与STAT3蛋白的线粒体导入密切相关。N，N-二乙基-7-氨基香豆素是一种荧光的线粒体靶向探针。在这项研究中，通过将N，N-二乙基-7-氨基香豆素荧光团与苯并[ b ]噻吩1，1-二氧化物部分相连，开发了一系列STAT3抑制剂。所有设计的化合物均显示出对癌细胞有效的抗增殖活性。代表性化合物7a主要通过荧光可见的线粒体中积累。化合物7a在Tyr705和Ser727残基均抑制STAT3磷酸化。化合物7a抑制STAT3磷酸化，而对STAT1，JAK2，Src和Erk1 / 2的磷酸化水平没有影响，表明化合物7a具有良好的选择性。此外，化合物7a下调STAT3靶基因Bcl-2和Cyclin D1的表达，增加ROS的产生并显着降低线
