Introduction

Doxorubicin (DOX) is a widely used chemotherapeutic agent known for its efficacy against various solid tumors. However, its clinical use is significantly hampered by the risk of developing doxorubicin-induced cardiotoxicity, which is primarily mediated by the generation of reactive oxygen species (ROS) leading to oxidative stress and subsequent damage to myocardial tissues. This study investigates the potential cardioprotective effects of the aqueous extract of Santalum album (SAAE), a medicinal plant traditionally used in various herbal formulations for its therapeutic properties, including cardioprotection.

Antioxidant Activity of Santalum album

The in vitro antioxidant activity of S. album was measured using multiple methods, including the reducing power assay and scavenging activities against hydrogen peroxide and superoxide radicals. The results indicated that the extract possesses significant antioxidant capabilities, showing that higher concentrations of SAAE enhanced its reducing potential and scavenging ability. For instance, the IC50 for hydrogen peroxide decomposition was 17.27 µg/ml for SAAE, compared to 6.05 µg/ml for ascorbic acid, suggesting that while it has potent activity, it is less effective than ascorbic acid, a known antioxidant reference standard. This preliminary assessment points to S. album's potential in neutralizing oxidative stress, lending support to its use as a cardioprotective agent.

Protective Effects Against Cardiotoxicity

The study employed a rat model to assess the protective effects of SAAE against DOX-induced cardiotoxicity, with specific focus on biochemical markers and myocardial integrity. Administration of DOX led to a marked increase in levels of cardiac markers such as malondialdehyde (MDA), lactate dehydrogenase (LDH), and creatine kinase-MB (CK-MB) in serum, indicating oxidative damage. Conversely, treatment with SAAE significantly reduced these markers, demonstrating its ability to mitigate lipid peroxidation and preserve cardiac function. This finding underscores SAAE's role in counteracting oxidative stress imposed by DOX, contributing to the maintenance of cardiac health.

Cytokine Regulation and Apoptosis Mitigation

Further investigation into the mechanistic aspects revealed that DOX treatment significantly elevated pro-inflammatory cytokines such as IL-6 and TNF-α, which are implicated in inflammation and apoptotic pathways. SAAE demonstrated a notable reduction in the levels of these inflammatory markers when administered prior to DOX treatment, suggesting its capability to exert anti-inflammatory effects. Additionally, the study found a substantial decrease in caspase-3 activity in the hearts of rats treated with SAAE, indicating a protective role in preventing apoptosis in myocardial tissues. This suggests that SAAE not only combats oxidative stress but also modulates the inflammatory response, thereby preventing myocardial damage from drug-induced apoptosis.

Conclusion

In conclusion, the findings of this study provide compelling evidence of the cardioprotective effects of Santalum album against doxorubicin-induced cardiotoxicity. The extract's antioxidant properties, coupled with its ability to regulate inflammatory cytokines and mitigate apoptotic pathways, highlight its potential as a novel therapeutic agent for enhancing cardiac resilience in patients undergoing chemotherapy with DOX. This research lays the groundwork for further exploration and development of S. album in clinical settings aimed at preventing or reducing the cardiotoxic effects associated with anthracycline treatment.
