Salvianolic acid D: A potent molecule that protects against heart failure induced by hypertension via Ras signalling pathway and PI3K/Akt signalling pathway.

ABSTRACT:

Ethnopharmacological relevance

Salvianolic acid D (Sal D) is a natural substance extracted from Radix Salviae that performs a cardiovascular benefit. However, the protective mechanism of Sal-D for heart failure remains uncertain.

Aim of the study

In this study, we aim to evaluate the effect of Sal D on heart failure and elucidate its underlying mechanisms.

Materials and methods

Using the spontaneously hypertensive rats (SHR) as a cardiac remodelling model, the cardioprotective effect of Sal D was evaluated. Employing bioinformatics analysis, the related mechanisms of Sal D treatment on heart failure were identified and validated by Western blot and polymerase chain reaction.

Results

The results showed that Sal D significantly improved cardiac function and attenuated cardiac hypertrophy. Besides, Sal D impaired mitochondrial structure and restored the energy charge of cardiomyocytes managed by angiotensin II. Bioinformatics analysis suggested that Sal D might improve heart failure by modulating the Ras and PI3K/AKT signalling pathways verified in vitro and in vivo.

Conclusion

In summary, Sal D can improve the heart function of SHR by inhibiting the Ras signalling pathway and activating the PI3K/AKT signalling pathway.
