Hepatic stellate cell (HSC) activation is a crucial event in the progress of liver fibrosis. In this study, the target of helenalin was firstly predicted by bioinformatics anal., and then the prediction was verified by various experiments The HSC-T6 cells were activated by interleukin-1 beta (IL-1β) and then treated with helenalin. Moreover, HSC-T6 cells were transfected with miR-200a mimic or inhibitor, and the effect of helenalin on the miR-200a-mediated PI3K/Akt and NF-κB signaling pathways was investigated. The bioinformatics anal. indicated that miR-200a might regulate the PI3K/Akt pathway, NF-κB activation, Bcl-2 family and Caspases, ultimately affecting cell survival and apoptosis. Interestingly, the mol. docking demonstrated that the target of helenalin might be miR-200a-mediated the PI3K/Akt and NF-κB pathways. Moreover, the experiments showed that helenalin administration led to the inactivation of HSC-T6 cells, as evidenced by the inhibition of cell proliferation, α-SMA expression and collagen production The mechanism studies showed that helenalin reduced collagen accumulation by restoring the balance of MMPs/TIMPs. Moreover, helenalin markedly suppressed HSC activation by inhibiting the PI3K/Akt pathway and alleviated inflammatory response by blocking the NF-κB signal transduction. Further study indicated that helenalin up-regulated miR-200a expression, thus leading to the inhibition of the PI3K/Akt and NF-κB signaling pathways. In conclusion, helenalin inhibits HSC activation via inhibiting the miR-200a-mediated PI3K/Akt and NF-κB pathways, and it may be developed as a potential medicine for the treatment of liver fibrosis. And (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) was used in the research process.
