== Publication Abstract from PubMed ==
 +
Acute nonbacterial gastroenteritis caused by noroviruses constitutes a global public health concern and a significant economic burden. There are currently no small molecule therapeutics or vaccines for the treatment of norovirus infections. A structure-guided approach was utilized in the design of a series of inhibitors of norovirus 3CL protease that embody an oxazolidinone ring as a novel design element for attaining optimal binding interactions. Low micromolar cell-permeable inhibitors that display anti-norovirus activity have been identified. The mechanism of action, mode of binding, and structural rearrangements associated with the interaction of the inhibitors and the enzyme were elucidated using X-ray crystallography.
