A series of nondeuterated and deuterated dipeptidyl aldehyde and masked aldehyde inhibitors that incorporate in their structure a conformationally constrained cyclohexane moiety was synthesized and found to potently inhibit severe acute respiratory syndrome coronavirus-2 3CL protease in biochemical and cell-based assays. Several of the inhibitors were also found to be nanomolar inhibitors of Middle
