Title
(EN) COCRYSTALS OF AXITINIB AND GLUTARIC ACID, AND PREPARATION METHOD THEREFOR
(FR) COCRISTAUX D'AXITINIB ET D'ACIDE GLUTARIQUE, ET LEUR PROCÉDÉ DE PRÉPARATION
(ZH) 一种阿西替尼与戊二酸共晶及其制备方法
Abstract
(EN) Disclosed in the present invention are cocrystals of axitinib and glutaric acid, and a preparation method therefor. In the cocrystals of axitinib and glutaric acid, the molar ratio of axitinib to glutaric acid is 1:1. The preparation method of the cocrystals of axitinib and glutaric acid features simple technology, an easy-control crystallization process, and good reproducibility, and is suitable for industrial production. Compared with axitinib, the cocrystals of axitinib and glutaric acid have a greater apparent solubility and a faster dissolution rate, and facilitate improving the oral bioavailability of axitinib.
(FR) La présente invention concerne des cocristaux d'axitinib et d'acide glutarique, et leur procédé de préparation. Dans les cocristaux d'axitinib et d'acide glutarique, le rapport molaire entre l'axitinib et l'acide glutarique est de 1 : 1. Le procédé de préparation des co-cristaux d'axitinib et d'acide glutarique a une technologie simple, un procédé de cristallisation facile à commander et une bonne reproductibilité, et est approprié pour une production industrielle. Les co-cristaux d'axitinib et d'acide glutarique, par comparaison avec l'axitinib, ont une solubilité apparente supérieure et une vitesse de dissolution plus rapide, et facilitent l'amélioration de la biodisponibilité orale d'axitinib.
(ZH) 本发明公开了一种阿西替尼与戊二酸共晶及其制备方法。这种阿西替尼与戊二酸共晶中,阿西替尼与戊二酸的摩尔比为1:1。这种阿西替尼与戊二酸共晶的制备方法工艺简单,结晶过程易于控制,重现性好,适用于工业化生产。该阿西替尼与戊二酸共晶较阿昔替尼具有较大的表观溶解度和较快的溶出速率,有利于提高阿昔替尼的口服生物利用度。
