Elucidating Molecular Interactions of Natural Inhibitors with HPV-16 E6 Oncoprotein through Docking Analysis

Area of Science:

• Oncology
• Virology
• Computational Chemistry

Background:

• Human papillomavirus (HPV) infection is a primary cause of cancer mortality in women globally.
• Developing novel anticancer drugs is critical to combat life-threatening HPV infections.
• Natural compounds offer a promising avenue for anticancer therapy against HPV.

Purpose of the Study:

• To investigate natural compounds as inhibitors against the HPV-16 E6 oncoprotein.
• To understand the interaction mechanism between natural inhibitors and the E6 oncoprotein using structure-based drug design.
• To explore the potential of these compounds in restoring p53 tumor suppressor protein function.

Main Methods:

• A homology model of the HPV-16 E6 oncoprotein was constructed.
• Structure-based drug design approach was employed.
• Molecular docking analysis was performed to predict interactions between natural compounds and the E6 protein.

Main Results:

• Docking analysis revealed interactions between natural compounds and the p53-binding site of the E6 protein (residues 113-122).
• These interactions suggest the potential restoration of p53 tumor suppressor protein functioning.
• In silico validation of natural compounds and insights into molecular mechanisms of protein-ligand interactions were achieved.

Conclusions:

• Natural compounds demonstrate potential as therapeutic agents against HPV-16 E6 oncoprotein.
• Computational drug design can effectively identify and validate natural inhibitors for HPV-related cancers.
• Further research into these natural compounds could lead to new anticancer drug development for HPV infections.
