Abstract Objective To investigate the inhibitory nature of hydroxychavicol against the COVID-19 associated mycotic infections, the present in silico study was performed in hydroxychavicol with the target Lanosterol 14 alpha demethylase and its competency was compared with four approved anti-fungal drugs. Significance The corona virus pandemic has drawn stark lines between rich nations and poor, and the occurrence of COVID-19 associated mycotic infections, mucormycosis epidemic stands as the latest manifestation. The increase in resistance in known fungal pathogens to the available anti-fungal drugs and side effects are the important demands that forced to search anti-fungal compounds from medicinal plants as therapeutic alternatives. During the fishing expedition, Piper betle L., gets tremendous attention for its rich source of medicinally important compounds. Among them, hydroxychavicol has the enormous supportive records against microbial growth. Methods Hydroxychavicol and the chosen drugs were retrieved from the Pubchem database and subjected to ADME analysis. The structure of the target of the chosen COVID-19 associated fungal pathogens was retrieved from PDB and unavailable protein structures were modeled using the Swiss Model and validated. Virtual screening (PyRx version 0.8) was performed and the interactions were visualized using BIOVIA Discovery Studio. Results ADME screening of hydroxychavicol was found to have clear reciprocity with the drug-likeliness nature and the subsequent molecular docking study revealed its good binding affinity toward the target protein suggesting its inhibitory nature. Conclusion This study offers the possibility of making use of the suppressive nature of hydroxychavicol in the treatment of mycotic infections either exclusively/in synergistic approach.
