The chemical structure of formononetin and time course assay. (A) The illustration of the protocol of viral adsorption and treatment with formononetin and pirodavir. SK-N-SH cells were infected with 80 pfu/well of EV71 (SHZH98). Formononetin (9.21 μM) and pirodavir (0.84 μM) was added at the indicated times, respectively. (B) The morphological changes of EV71-infected cells treated with or without formononetin and pirodavir were observed at 48 h post-infection. The cytopathic effect (CPE) assay was shown. (C) The chemical structure of formononetin.
