Identification of entecavir and imipenem as anti-inflammatory agents. a Entecavir hydrate, entecavir and imipenem suppressed the LPS-induced TNF-α elevation by 80 % in macrophages. b Entecavir showed the strongest TNF-α inhibitory effect compared with other antiviral drugs (ribavirin, abidol, ritonavir, remdesivir and lopinavir). *P < 0.05, **P < 0.01, ***P < 0.001 vs. entecavir. c TNF-α inhibitory effect of imipenem compared with moxifloxacin, ceftriaxone and azithromycin. d and e The dose-response curves for the TNF-α inhibitions of entecavir and imipenem exhibited IC50s of 2.0 and 11 μM, respectively. f and g Cell viabilities of macrophages with entecavir and imipenem treatment at different concentrations. **P < 0.01, ***P < 0.001 vs. 0.3125 μM group.
