Clinical Potential

Enterovirus 71 (EV71) and coxsackievirus A16 (CoxA16) are main pathogens of hand-foot-and-mouth disease, occasionally causing aseptic meningitis and encephalitis in tropical and subtropical regions.Kalanchoe gracilis,Da-Huan-Hun, is a Chinese folk medicine for treating pain and inflammation, exhibiting antioxidant and anti-inflammatory activities. Our prior report (2012) citedK. gracilisleaf extract as moderately active against EV71 and CoxA16. This study further rates antienteroviral potential ofK. gracilisstem (KGS) extract to identify potent antiviral fractions and components. The extract moderately inhibits viral cytopathicity and virus yield, as well asin vitroreplication of EV71 (IC50= 75.18 μg/mL) and CoxA16 (IC50= 81.41 μg/mL). Ethyl acetate (EA) fraction of KGS extract showed greater antiviral activity than that ofn-butanol or aqueous fraction: IC50values of 4.21 μg/mL against EV71 and 9.08 μg/mL against CoxA16. HPLC analysis, UV-Vis absorption spectroscopy, and plaque reduction assay indicate that eupafolin is a vital component of EA fraction showing potent activity against EV71 (IC50= 1.39 μM) and CoxA16 (IC50= 5.24 μM). Eupafolin specifically lessened virus-induced upregulation of IL-6 and RANTES by inhibiting virus-induced ERK1/2, AP-1, and STAT3 signals. Anti-enteroviral potency of KGS EA fraction and eupafolin shows the clinical potential against EV71 and CoxA16 infection.
