Abstract
Breast cancer is one of the most frequent invasive malignancies in women globally and the leading cause of mortality. The HER2 target is an important therapeutic option for treating breast cancer. In the present study, efforts have been made to virtually screen the natural kinase inhibitors through molecular docking. A total of 800 HER2 protein inhibitor compounds were selected to screen out the potential inhibitors of the HER2 protein. The docking study demonstrated that these HER2 protein inhibitors confirm the strong binding interaction with HER2 protein based on the docking score, indicating that kinase inhibitors can play a major role in preventing breast cancer. Among all the inhibitors, the flavanone compound named 6-C-(3-Hydroxyisopentyl) eriodictyol, IUPAC: 2-(3, 4- dihydroxyphenyl)-5, 7-dihydroxy-6-(3-hydroxy-3-methylbutyl)- 2, 3-dihydrochromen-4-one observed to have the maximum docking score value of (-8.717), indicating the highest binding affinity with HER2 protein which might serve as the promising compound for the development of a new class of drug to combat breast cancer.
