摘要

程序-1 核糖体框架转换(-1 PRF)是包括 SARS-CoV-2 在内的一些病毒采用的一种翻译机制。为了找到一种能抑制 SARS-CoV-2 中-1 PRF 的化合物,我们利用源自 HeLa 细胞提取物的无细胞蛋白质合成(CFPS)系统建立了一个高通量筛选系统。在以 -1 PRF-EGFP 为模板编程的 CFPS 系统中,共单独培养了 32,000 种化合物。观察到几种化合物降低了-1 PRF驱动的荧光,其中一种化合物对转染细胞中SARS-CoV-2基因组序列的-1 PRF有一定的抑制作用。因此,CFPS 系统可用作高通量筛选化学品的工具。

High-throughput screening for a SARS-CoV-2 frameshifting inhibitor using a cell-free protein synthesis system.

Programmed-1 ribosomal frameshifting (-1 PRF) is a translational mechanism adopted by some viruses, including SARS-CoV-2. To find a compound that can inhibit -1 PRF in SARS-CoV-2, we set up a high-throughput screening system using a HeLa cell extract-derived cell-free protein synthesis (CFPS) system. A total of 32,000 compounds were individually incubated with the CFPS system programmed with a -1 PRF-EGFP template. Several compounds were observed to decrease the -1 PRF-driven fluorescence, and one of them had some suppressive effect on -1 PRF of a SARS-CoV-2 genome sequence in transfected cells. Thus the CFPS system can be used as a tool for a high-throughput screening of chemicals.
