z lvg chn2

The diazomethyl ketone Z-LVG-CHN2 mimics part of the human cysteine proteinase-binding center, has been shown to be an irreversible inhibitor of this proteinase. The compound was also tested for antiviral activity against herpes simplex virus type 1 (HSV) and found to block the HSV replication. Irreversible inhibitor of streptopain.

Z-L(D-Val)G-CHN2（即Z-LVG-CHN2）是半胱氨酸蛋白酶抑制剂的异构体，作为一种三肽衍生物，模仿了人体半胱氨酸蛋白酶结合中心的部分结构。它可以抑制HSV，并且能有效阻断SARS-COV-2的3CL pro蛋白酶，从而抑制病毒活性（EC50=190 nM），但对脊髓灰质炎病毒复制无显著作用。
