Figure Lengend Snippet: The effects of Genipin and its derivatives on the pSIRT1 luc reporter and IAV infection in vitro . ( A ) MTT assay was used to determine the cytotoxicity of Gardenia jasminoides Ellis extract on A549 cells. ( B ) The inhibitory effect of Gardenia jasminoides Ellis extract on IAV (PR8) infection in vitro . ( C ) The structure of Genipin and its derivatives. ( D ) MTT assay was used to determine the cytotoxicity of Genipin on A549 cells. ( E ) The stimulating effect of Genipin and its derivatives on the pSIRT1 luc reporter. All groups were co-transfected with pSIRT1 luc and pRL-TK plasmids. Except for the control group (BG), all other groups were infected with IAV (MOI=0.01). The negative group (NG) and positive control group (PC) were treated with 0.5% DMSO and 50 μmol resveratrol (Res), respectively. All other groups were given Genipin and its derivatives at a dose of 50 μ mol. The data is expressed as the ratio of luciferase activity to its internal control. ( F, G, H and I ) The inhibitory effect of Genipin and its derivatives on IAV (PR8) infection. The negative control (NC) A549 cells were only infected with IAV (MOI=0.01) and treated with DMSO (0.5%, v/v). In the PC, Genipin, and their derivatives groups, A549 cells infected with IAV were treated with ribavirin (20 μg/mL), Genipin, and Genipin derivatives (6.25, 12.5, 25, 50 μmol), respectively. After 48 hours, collect the supernatant and measure the titer using the TCID50 method. The data were the mean ± standard deviation of three independent experiments. * Compared with the NC group, P<0.05.
