Cell extraction-UPLC-QTOF determination of the biological affinity of bufadienolides with HeLa cells and their correlation with properties computed from structure

Aim To assay the affinity rate of bufadienolides with HeLa cell line,and to analyze the correlation between the bioaffinity rates and the properties computed from structure of bufadienolides.Method The chloroform extract of Chansu was added into cultured HeLa cells.The contents of bufadienolides in the supernatant and cell were measured UPLC-QTOF.10 properties computed from structure of bufadienolides were collected from Pubchem database.Result The coefficient of correlation between XLogP3,H-Bond Donor and Topological Polar Surface Area with the decrease of bufadienolides in cell supernatant after affinity,was r= 0.865(P0.01),r=-0.901(P0.01),r=-0.657(P0.05),respectively.Other computed properties had no significant correlation with the bioaffinity rates.Conclusion Bufadienolides have different levels of affinity with HeLa cells,which correlates with their properties computed from structure.
