A recent computational study suggests that amygdalin, a natural compound found in almonds, peaches, and apples, could potentially inhibit HER2-positive breast cancer by binding to and stabilizing the HER2 receptor. HER2 overexpression is linked to aggressive breast cancer and poor prognosis. The study, employing advanced computational tools, revealed that amygdalin may suppress the cancer-promoting activity of HER2, paving the way for future therapeutic development. The study was published in LabMed Discovery.
The research team used molecular docking to analyze amygdalin’s binding affinity to HER2, finding favorable binding energies, particularly in the presence of water molecules. Further molecular dynamics simulations over 100 nanoseconds demonstrated that amygdalin induced structural changes in HER2, reducing flexibility in key regions associated with its inactive state. These changes suggest that amygdalin could effectively hinder HER2’s cancer-driving mechanisms.
Energy calculations highlighted that van der Waals forces primarily drove the binding, with specific amino acids in HER2 playing critical roles. The study also noted that water molecules enhanced the stability of the interaction.
“Our findings provide a strong theoretical basis for amygdalin as a HER2 inhibitor, but further experimental and clinical validation is essential,” said the lead author.
While the computational results are promising, the researchers emphasize the need for in vitro and clinical studies to confirm amygdalin’s efficacy. If validated, this natural compound could become a valuable addition to HER2-targeted breast cancer therapies.
