Abstract
Novel fluoroquinolone-pyrazine conjugates 7a-h with amino acid linkers were synthesized in good yields utilizing benzotriazole chemistry. Antimicrobial bioassay showed that the synthesized bis-conjugates have antimicrobial properties comparable to the parent drugs. Compound 7h showed superior antibacterial activity against Staphylococcus aureus and Streptococcus pyogenes (MIC=74.6 μM and 149.3 μM, respectively). This matched well with the estimated values obtained from 3D-pharmacophore and 2D-QSAR studies (MIC=67 μM and 92.9 μM, respectively).
