Lopinavir/ritonavir and similar substructures from catalog. The combination lopinavir/ritonavir is currently tested against COVID-19, but "no benefit was observed with lopinavir–ritonavir treatment beyond standard care". (doi: 10.1056/NEJMoa2001282) Reportedly, lopinavir has only mid-micromolar activity against SARS protease, ritonavir above 50 microM. (doi: 10.12688/f1000research.22457.1; doi: 10.1073/pnas.0403596101) However, there is no crystal structure of the 2019-nCoV main protease with either of these two drugs that could clarify their potential for optimization against this target. Thus, I suggest lopinavir, ritonavir, and reasonably similar substructures available from catalog for soaking. Procedure in KNIME: 1) search all substructures of lopinavir and ritonavir in MolPort 2) remove all redundant compounds and compounds with similarity < 0.5 (datawarrior SkelPheres) to either of the queries 3) remove all compounds void of a ring or containing amides (as substructures of amides) Selection not based on or compared to fragment hits; x0072 selected as dummy.
