ABSTRACT
Aim To explore the anti-inflammatory effect of natural compound Ginkgetin on lipopolysaccharide-induced mouse primary peritoneal macrophages and the underlying mechanism, in order to provide a theoretical basis for the development of clinical drug candidates. Methods MTT test kit was used to detect the cytotoxicity of Ginkgetin on mouse primary peritoneal macrophages; ELISA and RT-qPCR methods were used to detect the anti-inflammatory effect of different concentrations of Ginkgetin on LPS-induced cell inflammation injury model; Western blot was used to detect the anti-inflammatory mechanism of ginkgo flavonoids. Results Compared with LPS stimulation group, Ginkgetin treatment group produced a concentration-dependent anti-inflammatory effect, which could be attributed to the fact that Ginkgetin could inhibit LPS-induced activation of NF-κB signaling pathway. MTT results also showed that ginkgo flavonoids had little toxicity to mouse primary peritoneal macrophages. Conclusions Ginkgelin alleviates LPS-induced inflammatory injury of mouse primary peritoneal macrophages by inhibiting the activation of NF-κB signaling pathway. It is expected to be a natural monomer antiinflammatory drug candidate.
