    摘要:
    在用四氟硼酸亚硝酰进行某些α,β-不饱和酯的硝化反应中形成的活性中间体表现出高度活性α-羰基阳离子的预期行为。已观察到三种诊断性的反应类型,表明这些不稳定的阳离子的存在:(i)在Ritter反应中捕获,(ii)从丙基阳离子形成环丙烷,(iii)烷基的Wagner-Meerwein迁移。对所提出的中间阳离子的相对气相稳定性的半经验计算有助于合理化观察到的化学现象。

    Provided herein are nanobubbles designed for use in ultrasound-mediated ablation of cancer cells. The nanobubbles undergo ultrasound-mediated cavitation at an ablation threshold which is significantly decreased, relative to standard ultrasound- mediated treatment of cancer cells. In exemplary embodiments, the nanobubbles comprise an amphiphilic ABC triblock copolymer, wherein block A comprises a hydrophilic polymer, block B comprises a crosslinking polymer, and block C comprises a hydrophobic copolymer comprising (i) methyl methacrylate (MMA) and (ii) a fluorinated monomer, wherein the fluorinated monomer is present in the hydrophobic copolymer of block C at 25 mole percent or less. Related treatment and diagnostic methods, as well as materials relating to the nanobubbles are provided herein. Methods of making a random copolymer are furthermore provided herein.
    本文提供了设计用于超声介导癌细胞消融的纳米气泡。这些纳米气泡在消融阈值下经历超声介导的空化作用,相对于标准的超声介导癌细胞治疗,其消融阈值显著降低。在示范性实施例中,这些纳米气泡包括一种两性ABC三嵌段共聚物,其中嵌段A包括一个亲性聚合物,嵌段B包括一个交联聚合物,而嵌段C包括一个亲脂性共聚物,包括(i) 甲基丙烯酸甲酯MMA)和(ii) 一种化单体,其中化单体以25摩尔%或更低的比例存在于嵌段C的亲脂性共聚物中。此外,本文还提供了与纳米气泡相关的治疗和诊断方法,以及相关材料。此外,本文还提供了制备随机共聚物的方法。
