Combined spectroscopy and molecular modeling studies on the binding of galbanic acid and MMP9

Molecular docking results indicated that the main active binding site for GBA has been located in a hydrophobic cavity in the vicinity of Zn atom. Moreover, MD simulation results suggested that GBA as a coumarin derivative can interact with MMP9, without affecting the secondary structure of MMP9. MD simulations, molecular docking as computational methods from one hand and experimental data from other hand reciprocally supported each other.
