Ritonavir structure-activity relationships
WebIn response to the ongoing COVID-19 pandemic, there is a worldwide effort being made to identify potential anti-SARS-CoV-2 therapeutics. Here, we contribute to these efforts by building machine-learning predictive models to identify novel drug candidates for the viral targets 3 chymotrypsin-like protease (3CLpro) and RNA-dependent RNA polymerase … WebIn a continuing effort to identify structural attributes required for strong binding and potent inhibition of human drug-metabolizing CYP3A4, we designed ten ritonavir-like analogues differing in the side-group stereochemistry, backbone atomic composition, and headgroup spacing. All analogues had pyridine and tert-butyloxycarbonyl (Boc) as the heme-ligating …
