Abstract:
Objective To investigate the effect of Andrographis paniculata Nees(APN)extract on Coxsackievirus A16(CVA16)in vitro.Methods African green monkey kidney-derived Vero cells(Vero cells)were treated with APN extract at the concentration of 500.0,250.0,125.0,60.0,30.0,15.0,7.5 and 3.8 μg/mL,the cytotoxicity was determined with cell counting Kit-8 and the IC50was calculated by Probit unit regression method.Direct inactivating activity on CVA16,blocking of CVA16 adsorbing Vero cells and inhibition of CVA16 replication in Vero cells were determined and compared between Ribavirin(RBV) and APN extract with CVA16-infected Vero cells.SPSS 24.0 software was used to analyze the data.Results The selected concentrations of APN extract and RBV for experiment were 15.0, 7.5 and 3.8 μg/mL according to cytotoxicity test.Both of APN extract and RBV had neither direct inactivation on CVA 16 nor blocking of CVA16 adsorbing at the concentration of 15.0,7.5 and 3.8 μg/mL(F=1.54,1.52 and 0.67, 1.68,all P>0.05).However,both drugs had the capability of inhibiting CVA 16 replication in Vero cells at the concentration of 15.0 and 7.5 μg/mL(t=6.87,11.76 and 7.71,12.84,all P<0.05).Conclusion Experimental result shows that APN extract can effectively inhibit CVA 16 replication in Vero cells in vitro.
