  Trichogin GA IV: A versatile template for the synthesis of novel peptaibiotics

  摘要：

  从真菌长链毛霉中分离出来的 Trichogin GA IV 是具有膜修饰特性的短链肽亚类--脂链肽的原型。这种蛋白胨主要折叠成 310-/α- 混合螺旋构象，具有明显的两亲性，尽管这种两亲性并不强，但这很可能是它能够扰乱细菌膜并诱导细胞死亡的原因。在以前的论文中，我们曾报道过 trichogin GA IV 有趣的生物特性，即它对革兰氏阳性细菌（尤其是耐甲氧西林金黄色葡萄球菌菌株）的良好活性、对蛋白水解降解的稳定性以及较低的溶血活性。为了通过增加肽的螺旋两亲性来拓宽其抗菌活性谱，我们在这项工作中采用溶液法和固相法合成、纯化并充分表征了一组三叶草苷 GA IV 类似物、5、6、9 位的四个 Gly 残基被一个（2、5、6 或 9 位）、两个（5 和 6 位）、三个（2、5 和 9 位）和四个（2、5、6 和 9 位）Lys 残基取代。在水性、有机和膜模拟环境中，通过傅立叶变换红外吸收、CD 和二维核磁共振技术评估了含 Lys 类似物的构象偏好。有趣的是，事实证明，带电残基的存在会诱导七叶皂苷的螺旋构象（从 310 螺旋到 α 螺旋）随 pH 值的变化而发生转变，这是一个可逆的过程。通过在模型膜中的荧光泄漏实验、蛋白酶抗性、抗菌和抗真菌活性、细胞毒性和溶血作用，进一步检验了类似物显著增加的两亲性所发挥的作用。总之，我们的生物学结果证明，这些类似物中一些取代度最低的是开发新型膜活性抗菌剂的良好候选物。

• Allenone-Mediated Racemization/Epimerization-Free Peptide Bond Formation and Its Application in Peptide Synthesis

  peptide synthesis (SPPS). The robustness of the allenone-mediated peptide bond formation was showcased incisively by the synthesis of carfilzomib, which involved a rare racemization-/epimerization-free N to C peptide elongation strategy. Furthermore, the successful synthesis of the model difficult peptide ACP (65–74) on a solid support suggested that this method was compatible with SPPS. This method combines

  Allenone 首次被鉴定为一种高效的肽偶联剂。肽键以α-羰基乙烯基酯为关键中间体形成，其形成和随后的氨解以无外消旋/差向异构化的方式自发进行。丙二烯酮偶联试剂不仅对简单酰胺和二肽的合成有效，而且还适用于肽片段缩合和固相肽合成 (SPPS)。卡非佐米的合成充分展示了丙二烯酮介导的肽键形成的稳健性，该合成涉及一种罕见的无消旋化/差向异构化的 N 到 C 肽延伸策略。此外，在固体支持物上成功合成模型困难肽 ACP (65-74) 表明该方法与 SPPS 兼容。该方法结合了传统活性酯和偶联剂的优点，同时克服了两种策略的缺点。因此，这种丙二烯酮介导的肽键形成策略代表了肽合成的颠覆性创新。
