Figure Lengend Snippet: Virtual verification of Huaier targets by molecular docking. (a) Maestro 2D interactions between EGFR and gefitinib, adenosine, daucosterol, ergosterol, ergosta-7,22-dien-3β-ol and 3β-hydroxystigmast-5,22-dien-7-one. Residues in green spheres are hydrophobic, blue spheres are polar, red spheres are negatively charged, purple spheres are charged and light yellow spheres are glycine. The purple arrows and their directions represent hydrogen bonds between the ligand and the protein. The green line represents the π-π stacking arrangement seen between the aromatic core. (b) We conducted kinase activity assays to validate Huaier ’s inhibition on EGFR kinase activity. Staurosporine, an effective PKC inhibitor, was chosen as positive control. (c) Cells were conducted by CETSAs, and the protein expression of EGFR was detected by western blot analysis. The line chart showed the relative expression level of EGFR.
Article Snippet: Gefitinib and Daucosterol were both purchased from MCE (HY-50895; HY-N0410).
