Abstract
The rapid and efficient cocrystal screening, based on solution-mediated phase transformation (SMPT), was applied to the screening of cocrystals between ketoconazole (KTZ) and nine aliphatic dicarboxylic acids. Cocrystals formed successfully, in minutes, with a change of suspension characteristics, either a cake formation or the formation of large particles. Bulk cocrystals were characterized by powder X-ray diffraction, thermal analysis, and Raman spectroscopy. Single crystals were grown, and molecular structures were determined. Three previously reported cocrystals were reproduced, and six new cocrystals were discovered, including one that was reported as a failure in literature by solution or grinding method. Two hydrogen-bonded motifs are observed in these nine cocrystals: Most cocrystals form hydrogen bonded discrete tetramer with two KTZ and two acids molecules; while two cocrystals form infinite chain. This study demonstrated the high efficacy of cocrystal generation using the slurry screening method. It should be fully utilized in future cocrystal screening.
基于溶液介导相变(SMPT)的快速高效共晶体筛选方法被应用于酮康唑(KTZ)与九种脂肪族二羧酸共晶体的筛选。共晶体在几分钟内成功形成,悬浮特性发生了变化,要么形成了饼状,要么形成了大颗粒。粉末 X 射线衍射、热分析和拉曼光谱对块状共晶体进行了表征。对单晶体进行了生长,并确定了分子结构。再现了以前报道过的三种共晶体,并发现了六种新的共晶体,其中包括一种文献报道的溶液法或研磨法失败的共晶体。在这九种共晶体中观察到两种氢键图案:大多数共晶体与两个 KTZ 分子和两个酸分子形成氢键离散四聚体;而两个共晶体则形成无限链。这项研究表明,利用浆料筛选法生成的共晶体具有很高的效率。在今后的共晶体筛选中应充分利用这种方法。
