vitro/in vivo (preclinical and clinical) studies against COVID-19 infection, for which hardly any effective drug is available to date. Due to complexity of its chemical structure, stereoselective and regioselective Heck arylation reactions at C-17 exocyclic double bond of AG-1 is a major challenge and we stepped forward to generate a small focused library of compounds. Among all the molecules, AG-12 and
基于针对 COVID-19 感染的计算机/体外/体内(临床前和临床)研究,穿心莲内酯 (AG-1) 被确定为一种有吸引力的支架,迄今为止几乎没有任何有效药物可用。由于其化学结构的复杂性,AG-1 的 C-17 环外双键的立体选择性和区域选择性 Heck 芳基化反应是一项重大挑战,我们着手生成一个小型的重点化合物库。在所有分子中,预计 AG-12 和 AG-13 具有比 AG-1 更好的药代动力学特征。经体内评价AG-12 和 AG-13 与使用 LPS 诱导的急性肺损伤模型的 AG-1 相比,AG-13 显示出对减少中性粒细胞计数、最小化氧化应激和抑制炎性细胞因子有希望的作用。此外,应进行先导优化,以开发潜在的天然产物驱动的疗法,以对抗 COVID-19 期间的急性呼吸窘迫综合征 (ARDS) 情况。
