  脂质化短α，γ-杂交肽的有效抗菌活性

  摘要：

  本文中，我们报告了由1：1交替的α-和γ-氨基酸组成的α，γ-混合脂肽的有效抗菌活性。这些杂合脂肽除了具有针对各种革兰氏阳性和革兰氏阴性细菌的强效抗菌活性外，还具有较小的溶血作用。对作用机理的研究表明，这些短阳离子脂肽结合并破坏细菌细胞膜。时间杀灭动力学分析表明，有效的α，γ-混合脂肽可在不到20分钟的时间内完全抑制细菌生长。总体而言，这些α，γ-混合脂肽显示出令人鼓舞的抗菌活性以及较低的溶血活性，使其非常适合进一步探索有效的脂肽抗生素的设计。

  group has recently shown that brain-penetrant ataxia telangiectasia-mutated (ATM) kinase inhibitors may have potential as novel therapeutics for the treatment of Huntington’s disease (HD). However, the previously described pyranone-thioxanthenes (e.g., 4) failed to afford selectivity over a vacuolar protein sorting 34 (Vps34) kinase, an important kinase involved with autophagy. Given that impaired autophagy

  我们的小组最近表明，脑渗透性共济失调毛细血管扩张突变（ATM）激酶抑制剂可能具有作为治疗亨廷顿舞蹈病（HD）的新型疗法的潜力。但是，先前描述的吡喃酮-噻吨酮（例如，4）未能提供对液泡蛋白分选34（Vps34）激酶（一种与自噬有关的重要激酶）的选择性。鉴于自噬受损已被提出作为神经退行性疾病（如HD）的致病机制，因此对Vps34的选择性成为我们程序的重要目标。在这里，我们报告了通过使用Vps34-ATM蛋白嵌合体的X射线晶体结构成功完成了ATM在Vps34上的选择性优化，其中Vps34 ATP结合位点发生突变，近似于ATM激酶。由于选择性优化过程而产生的吗啉代-吡啶酮和吗啉代-嘧啶酮系列具有较高的ATM效能和良好的口服生物利用度，并且分子量较低，亲脂性降低，水溶性较高，

  The marine natural product hapalosin and 22 analogs, which incorporated systematic substituent deletions or variations, were prepared. These compounds were evaluated in a cell-based assay for both MDR-reversing activity and general cytotoxicity. Some substituent modifications resulted in lower cytotoxicities, but most structural changes were either detrimental to or did not seriously alter the MDR-reversing

  streamlined total syntheses of natural tubulysins such as V (Tb45) and U (Tb46) and pretubulysin D (PTb-D43), and their application to the synthesis of designed tubulysin analogues (Tb44, PTb-D42, PTb-D47-PTb-D49, and Tb50-Tb120), are described. Cytotoxicity evaluation of the synthesized compounds against certain cancer cell lines revealed a number of novel analogues with exceptional potencies [e.g., Tb111:
