FtsA as a cidal target for Staphylococcus aureus: Molecular docking and dynamics studies

Area of Science:

• Microbiology and Infectious Diseases
• Computational Chemistry and Drug Discovery
• Biochemistry and Molecular Biology

Background:

• Staphylococcus aureus infections pose a significant healthcare challenge due to increasing antibiotic resistance.
• Current treatments like vancomycin are facing potential resistance, necessitating the development of novel therapeutic agents.
• The FtsA protein, crucial for bacterial cell division, is a promising target for new antimicrobial drugs.

Purpose of the Study:

• To identify novel compounds targeting the FtsA protein in Staphylococcus aureus through virtual screening.
• To evaluate the binding affinity and stability of potential drug candidates with the FtsA protein.
• To explore ZINC74432848 as a potential lead compound for developing new antibiotics against S. aureus.

Main Methods:

• Virtual screening of the ZINC database against the FtsA protein.
• Molecular docking studies using SYBYL X 2.0 to assess binding interactions and scores.
• Simulation studies to determine the stability of the FtsA-compound complex.

Main Results:

• Virtual screening identified several hit molecules, with ZINC74432848, ZINC37769607, and ZINC96896268 showing high C-scores.
• ZINC74432848 exhibited the highest C-score (4.89) and formed four hydrogen bonds with the FtsA protein.
• Simulation studies confirmed the significant stability of the FtsA-ZINC74432848 complex.

Conclusions:

• ZINC74432848 is a promising candidate for a novel therapeutic agent targeting FtsA in Staphylococcus aureus.
• The identified compound demonstrates favorable binding and stability, warranting further in vitro and in vivo investigation.
• This research could lead to the development of a new drug to combat infections caused by drug-resistant S. aureus.
