  New Antimitotic Agents with Activity in Multi-Drug-Resistant Cell Lines and in Vivo Efficacy in Murine Tumor Models

  摘要：

  During a screen for compounds that could inhibit cell proliferation, a series of new tubulin-binding compounds was identified with the discovery of oxadiazoline 1 (A-105972). This compound showed good cytotoxic activity against non-multi-drug-resistant and multi-drug-resistant cancer cell lines, but its utility in vivo was limited by a short half-life. Medicinal chemistry efforts led to the discovery of indolyloxazoline 22g (A-259745), which maintained all of the in vitro activity seen with oxadiazoline 1, but also demonstrated a better pharmacokinetic profile, and dose-dependent in vivo activity. Over a 28 day study, indolyloxazoline 22g increased the life span of tumor-implanted mice by up to a factor of 3 upon oral dosing. This compound, and others of its structural class, may prove to be useful in the development of new chemotherapeutic agents to treat human cancers.

  芳基叠氮化物转化为氨基吡啶

  摘要：

  基本官能团相互转化的长期挑战是通过氮插入和碳缺失将苯直接转化为吡啶。在这里，我们报告了一种使用蓝光和氧气将芳基叠氮化物转化为 2-氨基吡啶的方案，该方案很容易从相应的苯胺中获得。机理研究证实，芳烃向吡啶的转化是通过将氮插入苯环，然后进行氧化碳挤出来实现的。

• Aromatic nitrogen scanning by <i>ipso</i> -selective nitrene internalization

  triggered C2-selective cheletropic carbon extrusion through a spirocyclic azanorcaradiene intermediate to afford the pyridine products. Because the ipso carbon of the aryl nitrene is excised from the molecule, the reaction proceeds regioselectively without perturbation of the remainder of the substrate. Applications are demonstrated in the abbreviated synthesis of a pyridyl derivative of estrone, as well

  芳基片段中的氮扫描是药物发现过程中一个有价值的方面，但由于缺乏直接的碳氮（C-to-N）合成，目前的策略需要对每种吡啶基异构体进行耗时、平行、自下而上的合成。 ) 置换反应。我们报告了一种可定点芳基C-N取代反应，允许通过氮宾内化过程统一获得各种吡啶异构体。在两步一锅法中，芳基叠氮化物首先通过光化学转化为 3 H -氮杂平，然后通过螺环氮杂环二烯中间体进行氧化触发的 C2 选择性螯合碳挤出，得到吡啶产物。由于芳基氮烯的自身碳被从分子中切除，因此反应可以区域选择性地进行，而不会干扰底物的其余部分。其应用已在雌酮吡啶基衍生物的简化合成以及原型氮扫描中得到证实。

  transformation of benzene into pyridine via nitrogen insertion and carbon deletion. Herein, we report a protocol for the transformation of aryl azides, easily accessible from their corresponding anilines, to 2-aminopyridines using blue light and oxygen. Mechanistic studies corroborate that the arene to pyridine conversion is achieved by nitrogen insertion into the benzene ring followed by oxidative carbon extrusion
