Abstract:
Background: Hydroxychloroquine (HCQ) is a common antimalarial drug that has
been used effectively in the treatment of various rheumatic and auto-immunity diseases. The major
side effects and drawbacks associated with HCQ are cardiotoxicity, retinopathy, gastrointestinal
upset, and neuromyopathy however, cardiotoxicity is an increasing concern and it is critical
to avoid heart dysfunction induced by HCQ. The present work is focused on receptor and signaling
molecules associated with pathways attributing to drug-induced cardiotoxicity. We analyzed
the therapeutic efficacy of selected natural products in HCQ-induced cardiotoxicity through insilico.
We selected Syzygium cumini polyphenols, quercetin, and p-coumaric acid. The motivation
behind selecting quercetin, and p-coumaric acid is their wide applicability as an antioxidative,
anti-inflammatory, antiapoptotic, and cardioprotective.
Methods: For predicting quercetin, p-coumaric acid, and HCQ toxicity and physicochemical
properties, in silico studies were performed using ProTox II and Swiss ADME. We further performed
molecular docking using Autodock Vina and Discovery Studio visualizer to find the affinity
of selected polyphenols against signaling molecules and receptors. Then we performed
network pharmacological studies of selected signaling molecules.
Results: We analyzed that the computational method indicated quercetin (Δ G -9.3 kcal/mol) has
greater binding affinity than p-Coumaric acid for prevention and restoration of the disease while
hydroxychloroquine was taken as a control.
Conclusion: It can be concluded that Syzygium cumini, polyphenols may aid in the future therapeutic
potential against HCQ-induced cardiotoxicity.
