Abstract:
Oridonin Inhibits SARS-CoV-2 Oridonin, a natural product extracted from Rabdosia rubescens, possesses a wide range of pharmacological properties, including anti-inflammatory, anti-cancer, anti-microbial, neuroprotection, immunoregulation, etc. In article number 2100124, Baisen Zhong, Litao Sun, and co-workers demonstrate that Oridonin targets the SARS-CoV-2 3CL protease by covalently binding to cysteine145 in its active pocket to exert an anti-SARS-CoV-2 effect, which provides a novel candidate for the treatment of COVID-19.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
Feedback Inhibition
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
