serves as reagent for aminosulfonation using pre-formed imidoiodinane as N-source. An investigation of the reaction mechanism was performed to implicate a process involving a N-centered radical. An additional method for sulfonamide installation is described that involves the use of commercially available reagents and operationally convenient conditions. Using the new synthetic methods, 22 compounds
多环烃 (PH) 作为药物化学中的亲脂性支架提供了有趣的潜力,但目前受限于可预测的 PH 单元修饰的合成工具的可用性。在此,我们报告了将磺胺装置安装到 PH 核心的新方法的开发。在第一种方法中,黄原酸酯用作氨基磺化试剂,使用预先形成的亚氨基碘烷作为 N 源。对反应机理进行了研究,以暗示涉及 N 中心自由基的过程。描述了另一种磺胺类药物安装方法,该方法涉及使用市售试剂和操作方便的条件。使用新的合成方法,制备了 22 种化合物,并筛选了针对 6 种哺乳动物细胞系以及革兰氏阳性和革兰氏阴性菌株的生物活性。生存力测定的结果已鉴定出比其他已知抗癌剂(如 indisulam 和 ABT-751)表现出更高效力的化合物。此外,合成化合物的物理化学和药物相似性已通过实验确定,并使用计算机预测工具。对磺胺插入 PH 核心的初步探索已经产生了许多值得进一步开发以生产具有治疗价值的分子的化合物。

hydrogen bond patterns. The use of QTAIMC and Hirshfeld surface analysis allowed elucidating the influence of functional groups and molecular arrangement on the strength of inter- and intramolecular non-covalent interactions in crystals and overall packing efficiency. It was found that the bulky memantine fragment hinders the formation of C(4) hydrogen-bonded chains, leading to the formation of dimeric
