Abstract

Heart failure (HF) remains a significant global health challenge, characterised by adverse ventricular remodelling, cardiomyocyte apoptosis, and elevated biomarkers such as B-type natriuretic peptide (BNP). Protocatechuic acid, a naturally occurring polyphenol, exhibits antioxidant and anti-apoptotic properties; however, its mechanistic effects in HF are not fully elucidated. Molecular docking analyses revealed strong binding affinities of protocatechuic acid with key apoptotic and stress-related proteins, including Bax, Bcl-2, Bcl-xL, Caspase-3, Caspase-9, Cytochrome c, and BNP, suggesting modulation of mitochondrial apoptosis and ventricular stress pathways. Protocatechuic acid also showed significant binding interactions with MMP-2 and MMP-9, indicating attenuation of extracellular matrix degradation and fibrotic remodelling. These findings demonstrate that protocatechuic acid exerts multi-target cardioprotective effects by modulating apoptotic signalling, reducing matrix metalloproteinase activity, and mitigating myocardial fibrosis, highlighting its therapeutic potential in HF management.
