Abstract
Aims: Design and synthesis of antimicrobial prototypes that are capable of eradicating bacterial biofilm formation that is responsible for many health challenges particularly with antibiotic-resistant bacterial species. Materials and Methods: The utility of 1,3-diarylenones, aka chalcones, 3a-i and 8a-j as building blocks to construct the corresponding bis-pyrazoline derivatives 5aa-bh and 9ad-bj. Screening the antibacterial behavior of the novel bis-pyrazoline derivatives against methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and vancomycin-resistant S. aureus (VRSA) bacterial strains was investigated. Results: Chalcones were used as building scaffolds to construct two series of di- and trisubstituted bis-pyrazoline derivatives. Numerous novel bis-compounds displayed decent bacterial biofilm suppression. Conclusions: Two regioisomeric series of bis-chalcones were designed and constructed, and their structural diversity was manipulated to access the intrinsically bioactive, pyrazoline ring. The newly synthesized bis-pyrazoline derivatives presented decent antibacterial behavior against multiple drug-resistant bacterial strands (MSSA, MRSA, and VRSA).
