The article was titled 《Optimization of triarylpyridinone inhibitors of the main protease of SARS-CoV-2 to low-nanomolar antiviral potency》.Safety of 3,3,3-Trifluoropropan-1-ol The article contains the following contents:
Non-covalent inhibitors of the main protease (Mpro) of SARS-CoV-2 having a pyridinone core were previously reported with IC50 values as low as 0.018μM for inhibition of enzymic activity and EC50 values as low as 0.8μM for inhibition of viral replication in Vero E6 cells. The series has now been further advanced by consideration of placement of substituted five-membered-ring heterocycles in the S4 pocket of Mpro and N-methylation of a uracil ring. Free energy perturbation calculations provided guidance on the choice of the heterocycles, and protein crystallog. confirmed the desired S4 placement. Here we report inhibitors with EC50 values as low as 0.080μM, while remdesivir yields values of 0.5-2μM in side-by-side testing with infectious SARS-CoV-2. A key factor in the improvement is enhanced cell permeability, as reflected in PAMPA measurements. Compounds 19 (I) and 21 (II) are particularly promising as potential therapies for COVID-19, featuring IC50 values of 0.044-0.061μM, EC50 values of ca. 0.1μM, good aqueous solubility, and no cytotoxicity.
