Case Study

Bromhexine Hydrochloride Used for the Inhibition of SARS-CoV-2 Spike Protein Binding via hACE-2 Interaction Modulation

Kehinde, Idowu A., et al. Journal of Molecular Graphics and Modelling 114 (2022): 108201.

Bromhexine hydrochloride (BHH), traditionally known as a mucolytic agent, has demonstrated promising potential in antiviral research through its interaction with human angiotensin-converting enzyme 2 (hACE-2), the primary receptor for SARS-CoV-2 cellular entry. In this computational study, BHH was investigated for its ability to disrupt the high-affinity binding between the SARS-CoV-2 spike protein and hACE-2, a critical step in viral attachment and host cell infection.
Molecular docking revealed that while BHH binding at the receptor-binding domain (RBD) interface had negligible impact on protein-protein interaction, its binding at the exopeptidase site of hACE-2 significantly reduced binding affinity between hACE-2 and the spike protein complex-from -64.856 kcal/mol (unbound) to -46.354 kcal/mol. This disruption was corroborated by residue interaction network analysis, which showed a marked reduction in amino acid contacts, indicating weakened spike-receptor binding
Furthermore, structural dynamics analysis confirmed that BHH induces notable conformational changes in the ACE2-spike complex, further supporting its potential inhibitory mechanism. Compared to ambroxol hydrochloride (AMB), BHH showed superior efficacy in attenuating spike-hACE-2 interactions.
These findings suggest that Bromhexine hydrochloride may serve as a potent inhibitor of SARS-CoV-2 entry by targeting the exopeptidase site of hACE-2, offering a promising repurposing strategy in antiviral therapeutics aimed at curbing viral infectivity.
