The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in-vivo and in-vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), and Interleukin-1β (IL-1β) were evaluated by enzyme-linked immunosorbent assay (ELISA). Subsequently, serum levels of myocardial enzymes lactate dehydrogenase (LDH) and creatine kinase (CK) were also assessed by ELISA kits. Ultimately, the cardioprotective and anti-inflammatory effects of 4-ACGC were further verified on CMECs. The results showed that the treatment of 4-ACGC significantly reduced cardiac hypertrophy and reversed the Ejection Fraction (EF), Heart Rate (HR), Fractional Shortening (FS), and Cardiac Output (CO) changes in CHF rats. The treatment of 4-ACGC could effectively inhibit the inflammatory cytokines induced by CHF. It’s also showed that a reverse effect of 4-ACGC on serum increased levels of LDH and CK in CHF rats. The increased levels of IL-1β and IL-6 stimulated by TNF-α on CMECs were also decreased after treating with 4-ACGC. The present study provided experimental evidence that 4-ACGC possessed obvious cardioprotective effects on attenuating CHF. 4-ACGC could suppress the expression of inflammatory mediators and myocardial enzymes, which might be one of the mechanisms.
