Middle East respiratory syndrome coronavirus (MERS-CoV) has emerged to cause fatal infections in patients in the Middle East and traveler-associated secondary cases in Europe and Africa. Person-to-person transmission is evident in outbreaks involving household and hospital contacts. Effective antivirals are urgently needed.We used small compound-based forward chemical genetics to screen a chemical...
In a previous study, severe acute respiratory syndrome coronavirus (SARS‐CoV) was cultured in the presence of bananin, an effective adamantane‐related molecule with antiviral activity. In the present study, we show that all bananin‐resistant variants exhibit mutations in helicase and membrane protein, although no evidence of bananin interference on their mutual interaction has been found. A structural...
Apart from bat-SARS-CoV, we have identified a novel group 1 coronavirus, bat-CoV HKU2, in Rhinolophus sinicus (Chinese horseshoe bats). Since it has been suggested that the receptor-binding motif (RBM) of SARS-CoV may have been acquired from a group 1 coronavirus, we conducted a surveillance study and identified bat-SARS-CoV and bat-CoV HKU2 in 8.7% and 7.5% respectively of R. sinicus in Hong Kong...
