Objective To predict the potential targets of apigenin by virtual screening .Methods The targets preliminarily forecast by PharmMapper ,were validated by associating data mining and Autodock Vina in PyRx 0 .8 .Subsequently ,receptor‐ligand interactions were analyzed by Discovery Studio 3 .5 .Results The virtual screening by PharmMapper indicated that apigenin coupled well with the disease‐related targets including insulin receptor ,estradiol 17‐beta‐dehydrogenase 1 ,and cathepsin K .According to the data mining ,insulin receptor was found in related experimental researches ,while the other two had few reports previously .And then ,the interactions between apigenin and the target proteins were analyzed by Autodock Vina and Discovery Studio Visualizer 3 .5 ,involving hydrogen bonds ,electrostatic forces ,van der Waals forces etc .Conclusion The most potential targets of apigenin were insulin receptor ,while 17‐beta‐dehydrogenase 1 and cathepsin K were also possible .

TNF signaling pathway was a valuable target ,and anti-TNF drugs were successfully used to treat autoim-mune and inflammatory diseases .But this therapy abrogate some beneficial TNF signaling ,leading to increased risk of infection and malignancy ,and the onset of new auto-immune diseases .Inhibiting the soluble TNF/TNFR1 axis while saving the benefi-cial transmembrane TNF/TNFR2 signaling untouched was a new approach .Because it inhibited the pathological effects of TNF and reduced the side effects ,and opened the way for the treatment of other diseases in which TNFR2 inhibition was detrimen-tal .The significance of the selective inhibition of TNFR1-mediated signaling pathways for TNF-related diseases was discussed and the mechanism of TNF identification TNFR was clarified ,which might provide new ideas for the design of new drugs .
