  超临界流体色谱中基于多糖的手性固定相的对映选择性。

  摘要：

  使用一组52种分析物在超临界流体色谱中评估了两种基于多糖的手性固定相对手性结构多样的生物活性化合物的对映选择性。固定在2.5μm二氧化硅颗粒上的手性选择剂是纤维素或直链淀粉的三（3,5-二甲基苯基carmabate）衍生物。监测了多糖主链，不同的有机改性剂和不同的流动相添加剂对保留和对映体分离的影响。对于大多数化合物，发现了快速基线对映体分离的条件。纤维素基手性固定相的基线和部分对映体分离的成功率分别为51.9％和15.4％。使用基于直链淀粉的手性固定相，我们获得了76。被测化合物的基线对映体分离率为9％，部分对映体分离率为9.6％。尤其是使用丙烷-2-醇以及异丙胺和三氟乙酸的混合物作为有机改性剂和CO添加剂时，在基于纤维素的手性固定相上获得了最佳结果2个。在基于直链淀粉的手性固定相上，优选甲醇和碱性添加剂异丙胺。纤维素和直链淀粉基手性固定相的互补对映选择性可分离大多数经测试的结构不同的化

  The separation of enantiomers of 16 basic drugs was studied using polysaccharide‐based chiral selectors and acetonitrile as mobile phase with emphasis on the role of basic and acidic additives on the separation and elution order of enantiomers. Out of the studied chiral selectors, amylose phenylcarbamate‐based ones more often showed a chiral recognition ability compared to cellulose phenylcarbamate

  使用基于多糖的手性选择剂和乙腈作为流动相，研究了16种基本药物的对映异构体的分离，重点研究了碱性和酸性添加剂对对映异构体的分离和洗脱顺序的作用。在研究的手性选择剂中，与纤维素苯基氨基甲酸酯衍生物相比，基于直链苯基氨基甲酸酯的选择剂更经常显示出手性识别能力。观察到甲酸作为添加剂对某些基本药物的对映体拆分和对映体洗脱顺序的有趣影响。因此，例如，几种β-阻滞剂（阿替洛尔，索他洛尔，甲苯酚）的对映异构体分离不仅可以通过在流动相中添加更常规的碱性添加剂来实现，而且可以通过添加酸性添加剂来实现。而且，手性27：228–234，2015年。©2015 Wiley Periodicals，Inc.

  Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.
