  摘要：

  Verinurad 是一种容易形成溶剂化物的两性 II 类阻转异构体，其制造路线已被证明非常复杂。这以前需要分离具有挑战性物理特性的中间体和低温工艺的应用。设计和优化了新工艺，能够以所需的多晶型生产 113 公斤的 verinurad。采用了涉及合成、高通量实验、分析化学、结晶科学、计算机建模和工程的跨学科方法。对映异构体富集的 verinurad 盐的动力学测量证实消旋化发生在清除时间范围内，从而减轻了与 verinurad 中固有的轴向手性相关的安全问题。

  低聚（萘-乙炔）分子棒

  摘要：

  为表面手性研究设计的分子棒已经以高产率合成。分子由低聚（亚萘基-乙炔基）骨架组成，并在其两个末端用羧酸和疏水基团官能化。分子骨架是通过钯催化的萘基卤化物和乙炔之间的 Sonogashira 反应构建的。三氮烯官能团用作受保护的碘前体，以允许在合成过程中分子棒的线性延伸。目标分子中的羧酸基团在合成过程中被保护为酯，以保持大芳香族分子在合成过程中的可溶性。这些刚性低聚物被设计成当吸附在表面上时形成层状结构，通过它应该可以获得多个可区分的表面构象。初步的扫描隧道显微镜成像证实了这些特性。

• Rigid aromatic linking moiety in cationic lipids for enhanced gene transfection efficiency

  synthesized. SAR studies showed that lipids with rigid aromatic linkage could promote the formation of tight liposomes and enhance DNA condensation, which is essential for the gene delivery process. These lipids could give much higher transfection efficiency than those containing more flexible aliphatic linkage in various cell lines. Moreover, the rigid aromatic linkage also affords the material higher serum

  尽管已开发出许多阳离子脂质作为非病毒基因载体，但这些材料的结构活性关系（SAR）仍不清楚，需要进一步研究。在这项工作中，设计并合成了一系列赖氨酸衍生的阳离子脂质，这些脂质包含具有不同刚性的键。SAR研究表明，具有刚性芳香键的脂质可以促进紧密脂质体的形成并增强DNA缩合，这对于基因传递过程至关重要。这些脂质比在各种细胞系中含有更灵活的脂族键的脂质具有更高的转染效率。而且，刚性的芳族键也使该材料具有更高的血清耐受能力。流式细胞仪检测表明目标脂质具有良好的细胞摄取，共聚焦显微镜观察显示，内体逃逸的能力比Lipofectamine 2000弱。为了解决该问题并进一步提高转染效率，人们使用了一些溶溶亲和试剂来改善脂质体的内体逃逸。如预期的那样，通过该策略可以获得比Lipofectamine 2000更高的转染效率。细胞毒性试验表明，这些脂质在各种细胞系中的毒性均低于Lipofectamine 200
