CNS penetrant potent inhibitor of SARS-CoV-2 Mpro that bind at the Mpro catalytic site
MR6-31-2, a CNS penetrant ebselen analog, is a potent inhibitor of SARS-CoV-2 Mpro that bind at the Mpro catalytic site. MR6-31-2 donates a selenium atom, forming a covalent bond and blocking the histidine-Cys catalytic dyad. It exhibits good neuroprotective effects and low cytotoxicity in cell-based and mouse models of motor neuron disease. MR6-31-2 covalently binds to A4V superoxide dismutase-1 (SOD1) and promotes its thermal stability.
