主客体相互作用代表了一个不断增长的研究领域,最近的工作表明,有能力化学操纵主体分子以及客体分子,以改变键合的类型和强度。关于客体分子和含有与典型大环主体相似化学特征的杂化材料的相互作用,知之甚少。这项工作使用在体外和体内动力学分析,以调查的相互作用的closo-dodecahydodecaborate衍生物与ferumoxytol,氧化铁纳米颗粒与羧化葡聚糖涂层。我们发现,几个硼簇衍生物可以成为封装到ferumoxytol和缺乏pH值的依赖性,在这些相互作用表明,离子配对,疏水/亲水,或氢键不是在这个系统中的封装的驱动力。在BALB/c小鼠中的生物分布实验表明,该系统在所报道的剂量下是无毒的,并证明在ferumoxytol中包封基于十二硼酸酯的簇可以改变客体分子的生物分布。
Host-guest interactions represent a growing research area with recent work demonstrating an ability to chemically manipulate both host molecules as well as guest molecules to vary the type and strength of bonding. Much less is known about the interactions of guest molecules and hybrid materials containing similar chemical features to typical macrocyclic hosts. This work uses in vitro and in vivo kinetic analyses to investigate the interaction of closo-dodecahydrododecaborate derivatives with ferumoxytol, an iron oxide nanoparticle with a carboxylated dextran coating. We find that several boron cluster derivatives can become encapsulated into ferumoxytol and the lack of pH dependence in these interactions suggests that ion pairing, hydrophobic/hydrophilic, or hydrogen bonding are not the driving force for encapsulation in this system. Biodistribution experiments in BALB/c mice show that this system is nontoxic at the reported dosage and demonstrate that encapsulation of dodecaborate-based clusters in ferumoxytol can alter the biodistribution of guest molecules.
