ABSTRACT
Computer-aid molecular
docking is a simulative process that receptors and ligands recognize each other
through energy matching and geometric matching. It is widely used in bioactive
compounds simulative screening and preliminary exploring the bioactivity and
toxicity of molecular, which plays an important guiding role in toxicity and bioactivity study
of molecular entities. In our study, we used the computer-aid molecular docking
software-discovery studio 3.1 client to test the mechanism of aflatoxins such
as aflatoxin B1, B2, M1, M2, G1, G2 and the results of our experiment help to
illustrate the pathway of aflatoxin’s toxication. We also used this technology
to test the preliminary toxicity of zearalenone (ZEN) and its two degradation
products: α-zearalenol (α-ZOL) and β-zearalenol (β-ZOL), which indicates that
these three products possessed significant estrogenic activity. The order of
the estrogenic activity is: α-zearalenol
> zearalenone >
β-zearalenol.
