In silico Exploration and Synthesis of New Quinazolinones as Antimicrobialsusing a Computational Approach

Introduction: Quinazolinone molecules have been investigated through diverse in silico studies and innovative designs for treating microbial infections. Microbial infections are amongst the most common health problems. Further, antimicrobial drugs have been showing resistance against microbial infections. Materials and Methods: Quinazolinone compounds have been designed and synthesized for the newer molecules via different approaches. The target compounds were formed using a synthetic method and confirmed by spectral analysis. The designed modeling of synthetic achievement, Benzoxazinone (3), was derived from anthranilic acid (1) and aromatic acid chloride (2) in the presence of pyridine, and further reacted to aminoacetophenone (4) formed 2-phenyl-amino-quinazolinone (5), afforded to then intermediate derivatives (7) react with p-chlorobenzaldehyde (6), then further reacted with aromatic substituted amines, with copper iodide, and reflux, 15 h, in a flask containing anhydrous dimethylformamide, potassium carbonate to formed the targeted newer quinazolinone derivatives motifs (A8a-j) shown in the Scheme 1. Results: In the results, we showed that the newer quinazolinone compounds A8b and A8f have been the two best compounds out of ten. The molecules were excellent parameters, including molecular dynamics simulations, docking scores, and physicochemical properties, when compared to the reference drugs. To examine the computational and structural basis of the relation between the test for in vitro antimicrobial activity Discussion: The newer synthesized and designed molecules were evaluated and observed to possess good in vitro antimicrobial activity. We have demonstrated that the in-silico studies of the biological relationships are well-closed with standard drugs. Conclusion: In conclusion, we find that there are good relations to antimicrobial properties, supported by in silico studies of the best compounds A8b and A8f. The findings confirm that newer quinazolinone molecules have the most promising relationships between in silico studies and biological validation for the next generation of antimicrobial agents.
