Title: Design and molecular docking of novel 5-O-Benzoylpinostrobin derivatives as anti-breast cancer


The benzoylpinostrobin derivative shows affinities for estrogen receptors ? and ?, progesterone receptors, and human epidermal growth factor receptor 2 (HER2), both in the form of binding to agonist and antagonist ligands, but the highest was shown against HER2 receptors by 4-nitro-5-O-benzoylpinostrobin. The ligand provided the most negative ?G and the lowest Ki toward the antagonist form of HER2 with -12.79 kcal/mol and 0.42 nM, respectively. That affinity is 4 times higher than lapatinib, which is known as a potent HER2 inhibitor. Interestingly, the ligand has fewer Van der Waals interactions with amino acids than lapatinib, but the affinity shown is higher.
