Pinostrobin, a flavanone isolated from various medicinal plants, is known to have various potential pharmacological activities, one of which is anti-breast cancer. Derivatization of pinostrobin to increase its activity has been reported previously but has never been carried out for aminomethyl derivatives. This study aims to determine the 6-aminomethylpinostrobin derivative with the best potential as anti-breast cancer through in silico studies. The method used was molecular docking using AutoDock Vina, with 10 6-aminomethylpinostrobin derivatives as test ligands and five receptors related to breast cancer. The docking results showed that 6-aminomethylpinostrobin derivatives showed the best potential against HER2 and EGFR receptors among the five receptors. Meanwhile, the derivatives with the best potential are 6-(N-dicyclohexylamine)methylpinostrobin and 6-(N-diphenylamine)methylpinostrobin, with potential affinity exceeding lapatinib on HER2. In conclusion, 6-aminomethylpinostrobin derivatives show promising potential as anti-breast cancer through HER2 inhibition and need to be proven in further studies both in vitro and in vivo.
