Abstract

Background: Early childhood caries (ecc) is increasingly associated with oxidative stress and dysregulation of antioxidant defense pathways. Glyphosate, a widely used environmental herbicide, has been reported to induce oxidative stress; however, its molecular interaction with key antioxidant regulators in ecc remains unclear.

Aim: To evaluate the interaction of glyphosate with keap1 and heme oxygenase-1 (ho-1) using molecular docking and explore its implications in oxidative stress pathways related to ecc.

Materials and Methods: An in silico docking study was performed using autodock vina. The keap1 kelch domain (pdb id: 2flu) and ho-1 (pdb id: 1n45) were selected as targets. Glyphosate (pubchem cid: 3496) was docked into the active sites, and interactions were analyzed using pymol and discovery studio.

Results: Glyphosate exhibited moderate binding affinity toward keap1 (−5.0 kcal/mol) and ho-1 (−4.5 kcal/mol), with interactions predominantly mediated by hydrogen bonding, electrostatic forces, and water-mediated contacts. A relatively higher affinity was observed for keap1.

Conclusion: Glyphosate may weakly modulate the keap1–nrf2–ho-1 pathway, potentially contributing to oxidative stress in ecc. Further experimental validation is required.
