Abstract

There are no effective antiviral drugs to treat hand, foot, and mouth disease. In this study, a series of lycorine derivatives were synthesized and evaluated against enterovirus 71 and coxsackievirus A16 in vitro. Derivatives 7c-m with the phenoxyacyl group at the C-1 position showed higher efficacy and lower toxicity than lycorine. In addition, derivative 7e enhanced the survival rate to 40% in the mouse model of the lethal EV71 infection.

赖氨酸衍生物的合成及其抗病毒活性

摘要

没有有效的抗病毒药物来治疗手足口病。在这项研究中，合成了一系列的lycorine衍生物，并在体外针对肠病毒71和柯萨奇病毒A16进行了评估。在C-1位置带有苯氧酰基的衍生物7c-m比番茄红素具有更高的功效和更低的毒性。此外，在致命的EV71感染的小鼠模型中，衍生物7e将存活率提高到40％。
