Machine Learning‐Driven Discovery of Structurally Related Natural Products as Activators of the Cardiac Calcium Pump SERCA2a

open access: yesChemMedChem, Volume 20, Issue 9, May 5, 2025.
Heart failure involves reduced SERCA2a activity, crucial for calcium regulation in heart cells. This study reports machine learning screening of 57,423 natural products, identifying several structurally related SERCA2a activators. Three compounds enhance calcium transport in cardiac cells, despite off‐target effects, offering promising hits for ...
