Antiviral activity of DMO-CAP against IAV. a Antiviral activity of DMO-CAP in RAW264.7 cells against A/Fort Monmouth/1/1947 (H1N1) and IAV A/Wuhan/359/1995 (H3N2) was tested by viral titers assay. b and c DMO-CAP reduced the expression of M2 RNA and protein in MDCK cells by one-step qRT-PCR assay and Western blot assay. d DMO-CAP reduced the expression of M2 protein by immunofluorescence. e DMO-CAP reduced the expression of M2 protein of influenza resistant strains by Western blot assay. Mock: normal cells without treatment; H1N1: cells were infected with IAV A/FM1/1947 at 0.01MOI; H3N2: cells were infected with IAV A/Wuhan/359/1995 (H3N2) at 0.01MOI. Con: cells were infected pathognomonic viral strains and treated with equal amounts of DMSO or DMO-CAP. The experiments were performed in triplicate and the data represents mean ± SD. ***P < 0.001, **P < 0.01, *P < 0.05 versus Con
