A summary of the article is shown below:

A recently reported potent inhibitor of enterovirus 71 3C protease, ( R)-1, was found to have stability and potential toxicity issues due to the presence of a cyanohydrin moiety. Modifying the labile cyanohydrin moiety, by serendipity, led to the discovery of 4-iminooxazolidin-2-one-based inhibitors 4e and 4g with potent inhibitory activity and significantly improved stability. In vivo pharmacokinetic studies of 4e also demonstrated high plasma exposure and moderate half-life. These compounds have shown potential of becoming anti-EV71 drug candidates.
