Abstract Investigation of multiple crystal forms of a substance and how these forms influence their properties are of great importance to the medicinal chemistry field, impacting strongly on the discovery of new drugs such as anticancer agents. Specifically, some chalcones and sulfonamides have been reported as anticancer agents. However, since such biological activity is related to both molecular
摘要 研究一种物质的多种晶型以及这些晶型如何影响其性质对药物化学领域具有重要意义,对抗癌药物等新药的发现具有重要影响。具体而言,一些查耳酮和磺胺类药物已被报道为抗癌剂。然而,由于这种生物活性与分子结构和超分子排列有关,因此了解化合物可能形式的作用非常重要。本文制备了一种新型磺酰胺查耳酮 (E)-2,5-二氯-N-(3-(3-(3-硝基苯基)丙烯酰基)苯基)苯磺酰胺,并得到两种不同晶型,多组分结晶连同丙酮 (I) 和一种单一组分,显示出命名为 (II) 的构象异构现象。通过单晶 X 射线衍射、Hirshfeld 表面和热分析来评估丙酮对这两种晶型超分子排列的影响。两个分子的晶体堆积通过 CH⋯O、NH⋯O 和 CH⋯Cl 的相互作用稳定。在 I 中,丙酮分子负责结合两个二聚体链,而在 II 中,溶剂空间在精修时被空隙取代。此外,通过差热分析和热重分析证实溶剂分子的存在是从 108 °C 开始的放热峰。I

corroborated by the low angle between the aromatic rings (5.23°). In addition, intermolecular interactions of type C–H⋯O and N–H⋯O make up a dimeric supramolecular arrangement. An inverse virtual screening approach allowed identifying potential biological applications for BSC, which indicated that BSC might interact with the binding sites of RARα and RARβ. Consequently, BSC was experimentally evaluated against
