Design and Molecular Docking Studies of Some 2,3 Di-Substituted Quinazolin-4-One Analogues Against Staphylococcus aureus UDG

Background: In this present investigation, some 2, 3 disubstituted-quinazolin-4-one derivatives are designed and docked against chain A and chain B of (3WDF) receptor. Methods: The heterocyclic fused rings quinazolinone have drawn a great attention owing to their expanded applications in the field of pharmaceutical chemistry. The diverse range of molecules with quinazoline/quinazolinone moieties have been reported to exhibit a broad spectrum of biological activities. Results: The results designate that the quinazolinone ring forms hydrophobic and hydrogen bond contacts with ASN 127 A, ALA 126 A, and SER 83 B, SER 183 B amino acid residue. Conclusion: Molecular docking is safe and straightforward to use tool which facilitates in investigating, interpreting, enplaning and identification of molecular properties using 3D structures.
