The principal component analysis (PCA) of the Mpro–velpatasvir (black), Mpro–glecaprevir (red), Mpro–grazoprevir (magenta), Mpro–baloxavir marboxil (cyan), Mpro–danoprevir (gray), Mpro–nelfinavir (blue), and Mpro–indinavir (green) complexes: (A) the 2D projection plot of the first two principal eigenvectors and (B) the plot of eigenvalues versus the corresponding eigenvector indices from the Cα covariance matrix during the MD simulations.
