prediction of the action of bromelain on PI3K/Akt signalling pathway to arrest nasopharyngeal cancer oncogenesis by targeting phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha protein  \nAlyaa Syafiqah Shamsuri 1 and Edmund Ui-Hang Sim 1*  \nAbstract  \nObjective This research investigates the potential anti-tumour effects of bromelain, an aqueous extract from pineapple stems and fruits, on nasopharyngeal cancer (NPC) . While bromelain is known for its medicinal properties in various cancers, its impact on NPC remains unexplored.  \nResults Using in silico methods, we studied the predicted interactions between bromelain and key proteins involved in NPC oncogenesis, specifically β-catenin, PIK3CA, mTOR, EGFR, and BCL2 . Molecular docking strategies were performed using a myriad of computational tools. A 3D model of bromelain was constructed using SWISS-MODEL, followed by molecular docking simulations performed with ClusPro. The binding affinities of the docked complexes were evaluated using HawkDock, and the interactions were analysed with LigPlot+ . The docking scores indicated potential spontaneous interactions, with binding affinities based on being − 103.89 kcal/mol (PIK3CA), -73.16 kcal/mol (EGFR), -71.18 kcal/mol (mTOR), -65.22 kcal/mol (β-catenin), and − 57.48 kcal/mol (BCL2) . LigPlot + analysis revealed the presence of hydrogen bonds, hydrophobic interactions, and salt bridges, indicating stable predicted interactions. Conclusion Our findings suggest that bromelain can target key proteins involved in NPC oncogenesis, with the strongest affinity towards PIK3CA. This suggests a hypothetical insight into bromelain’s anticancer effects on NPC through the modulation of the PI3K/Akt signaling pathway.  \nKeywords Nasopharyngeal carcinoma, Molecular docking simulation, Protein-protein interactions, Bromelain, PIK3CA  \n*Correspondence: Edmund Ui-Hang Sim [uhsim@unimas. my](uhsim@unimas. my)  \n1Faculty of Resource Science and Technology, Universiti Malaysia Sarawak, Kota Samarahan, Sarawak 94300, Malaysia  \n© The Author(s) 2024.

It is known to have medicinal properties such as antimicrobial, antithrombotic and anti-inflammatory effects [1]. Previous in vitro and in vivo studies have revealed its anticancer effects on various types of cancer such as lung [2, 3], brain [4], colorectal [5, 6], skin [7], and breast [8–10] cancer. However, to date, literature evidence of this effect on Nasopharyngeal carcinoma (NPC) is lacking, including those from insilico findings.  \nNPC is a type of head and neck squamous cell cancer (HNSCC) that is preferentially common in Asia, particularly Southeast Asia [11, 12].
