Inhibition of production of various pro-inflammatory cytokines, such as IL-1, IFNα
and TNF, which can protect against cytokine-mediated cartilage resorption

nelfinavir, lopinavir, ritonavir and ketoamide.
Homology modeling is a useful tool for predicting the
3D structure of proteins. Quality of the 3D structure of
protease of COVID-19 generated by SWISS-MODEL
server using 4MM3_B as the template was reasonably good
based on the validation reports generated Verify3D,
PROCHECK, and ProSA servers. Ramachandran plot
analysis suggests the predicted 3D model of protease of
COVID-19 as a good representation of protein structure
