improve its antiviral activity. The most active compound in this study was the iodinated emodin analogue E_3I, whose anti-HCoV-NL63 activity was comparable to that of remdesivir. Evaluation of the emodin analogues also revealed some unwanted toxicity to Vero cells. Since new synthetic routes are now available that allow modification of the emodin structure, it is reasonable to expect that analogues with
当前的 COVID-19 疫情凸显了开发新疫苗和药物来对抗严重急性呼吸系统综合症冠状病毒 2 (SARS-CoV-2) 的必要性。最近,多种药物被认为可能对 COVID-19 有效,例如瑞德西韦、英夫利昔单抗和伊马替尼。数千年来,天然植物一直被用作药物的替代来源,其中一些对治疗各种病毒性疾病有效。大黄素(1,3,8-三羟基-6-甲基蒽-9,10-二酮)是一种具有生物活性的蒽醌,具有抗病毒活性,存在于多种植物中。我们研究了大黄素核心上亲电芳香族取代反应(卤化、硝化和磺化)的选择性,从而产生了大黄素衍生物库。这项工作的主要目的是对提高大黄素对抗人类冠状病毒 NL63 (HCoV-NL63) 活性的潜力进行初步评估,并制定一套初步的 SAR 指南。我们制备了具有显着抗HCoV-NL63活性的大黄素衍生物。我们观察到大黄素的卤化可以提高其抗病毒活性。本研究中活性最强的化合物是碘化大黄素类似物E_3I
