The development of small molecule therapeutics to combat norovirus infection is of considerable interest from a public health perspective because of the highly contagious nature of noroviruses. A series of amino acid-derived acyclic sulfamide-based norovirus inhibitors has been synthesized and evaluated using a cell-based replicon system. Several compounds were found to display potent anti-norovirus activity, low toxicity, and good aqueous solubility. These compounds are suitable for further optimization of pharmacological and ADMET properties.

To achieve rapid and simultaneous detection of NoV GI, NoV GII, and HAV, a quadruple real-time fluorescence quantitative PCR (RT-qPCR) assay was developed using MS2 bacteriophage as a process control virus. The quadruple RT-qPCR assay effectively detected NoV GI, NoV GII, HAV, and MS2 RNA with detection limits of 10 copies/μL, 10 copies/μL, 10 copies/μL, and 10 copies/μL, respectively, within 1 hour 50 minutes. The quadruple RT-qPCR assay could specifically detect NoV GI, NoV GII, HAV, and MS2 without cross-reactions with other common pathogens, demonstrating good reproducibility with intra-assay and inter-assay coefficients of variation all below 2.

Human norovirus (HuNoV) infection is a global health and economic burden. Currently, there are no licensed HuNoV vaccines or antiviral drugs available. The protease encoded by the HuNoV genome plays a critical role in virus replication by cleaving the polyprotein and is, therefore, an excellent target for developing small molecule inhibitors.

Human noroviruses (HuNoVs) are the leading etiological agent causing the worldwide outbreaks of acute epidemic non-bacterial gastroenteritis. Histo-blood group antigens (HBGAs) are commonly acknowledged as cellular receptors or co-receptors for HuNoVs. However, certain genotypes of HuNoVs cannot bind with any HBGAs, suggesting potential additional co-factors and attachment receptors have not been identified yet.
