The first total synthesis of the potent antioxidant antiostatin A1 is reported, where its key features rely on a chemo- and regioselective rhodium-catalysed crossed alkyne cyclotrimerisation reaction applying functionalised ynamides and a palladium-catalysed arylamidation reaction.

The impact of LR-HSQMBC very long-range (n)JCH heteronuclear shift correlation data as a supplement to HMBC data as input for the computer-assisted structure elucidation program, Structure Elucidator(®), is assessed for the first time. The severely proton-deficient xanthone antibiotic cervinomycin A2 and the alkaloid staurosporine were employed as a model compounds.

Non-polio enteroviruses (NPEVs) are primary causative agents of aseptic meningitis, encephalitis, hand, foot and mouth disease (HFMD), myocarditis in infants children immunocompromised individuals. However, there no approved treatments for NPEVs. It has been reported that flavonoids abundantly found plants have antiviral activities. In this study, we explored the potential quercetin-3-glucoside...

A patient with cardiac arrest and documented torsade de pointes ventricular tachycardia is presented in whom acute coxsackievirus B2 myocarditis was identified as the most likely underlying cardiac condition. This case shows that torsade de pointes may occur as a rare manifestation of viral myocarditis. Serial serological tests and endomyocardial biopsies may be helpful in establishing a diagno...

Recombination events were found in two human coxsackievirus B3 strains, Beijing0811 and SD2012CHN. The strains were isolated separately from five newborns diagnosed with severe hospital-acquired acute myocarditis in Beijing in 2008 and from two children diagnosed with hand, foot, and mouth disease with concurrent acute myocarditis in Shandong in 2012.

Two coxsackievirus B5 (CVB5) strains were isolated from two children with aseptic meningitis in Australia. Their genomes were sequenced and found to be divergent from the previously reported CVB5 genome sequences, with both having 84% and 97% identities to the closest strains at the nucleotide and amino acid levels, respectively.

A series of substituted heteroaromatic piperazine and piperidine derivatives were found through virtual screening based on the structure of human enterovirus 71 capsid protein VP1. The preliminary biological evaluation revealed that compounds 8e and 9e have potent activity against EV71 and Coxsackievirus A16 with low cytotoxicity.
