We investigated the effects of FAN on Ang II\u2010induced cardiac remodelling and HF.\n                    <\/jats:p>\n                    <jats:p>Experimental Approach<\/jats:p>\n                    <jats:p>\n                      A hypertensive heart failure model was established in C57BL\/6 mice via 4\u2010week Ang II infusion. FAN was administered during the final 2\u2009weeks. Cardiac function was assessed by echocardiography and pathological remodelling was evaluated by histological staining. RNA sequencing of cardiac tissue was performed to investigate the mechanism of anti\u2010heart failure action of FAN. The potential binding proteins of FAN were verified by molecular docking, drug affinity response target stability (DARTS), cellular thermal shift assay (CETSA) and surface plasmon resonance assay (SPR).\n                      <jats:italic>In vitro<\/jats:italic>\n                      , neonatal rat ventricular myocytes (NRVMs) were used to investigate the effects of FAN on cellular hypertrophy, mitophagy and ferroptosis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Results<\/jats:title>\n                    <jats:p>\n                      <jats:italic>In vivo<\/jats:italic>\n                      , FAN treatment significantly ameliorated cardiac hypertrophy, dysfunction and fibrosis. These protective effects were independent of blood pressure\u2010lowering actions. Mechanistically, FAN activates PGC\u20101\u03b1 to enhance mitophagy and suppress STAT6\u2010PPAR\u03b3 signalling, thereby inhibiting ferroptosis and restoring redox homeostasis.\n                      <jats:italic>In vitro<\/jats:italic>\n                      , FAN reduced Ang II\u2010induced NRVM hypertrophy, ROS production and mitochondrial membrane potential depolarisation, and confirmed the modulation of mitophagy and ferroptosis markers.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and Implications<\/jats:title>\n                    <jats:p>We demonstrate that FAN alleviates Ang II\u2010induced HF through a mechanism involving the activation of PGC\u20101\u03b1\u2010mediated mitophagy and regulation of the STAT6\u2010PPAR\u03b3 pathway, ultimately suppressing cardiomyocyte ferroptosis.
