Abstract:

We report the antimicrobial activity of formylchromones. These compounds are remote structural analogues of nalidixic acid and quinolone antibiotics, and their activity was investigated by a simple micro-scale method designed for the determination of minimal inhibitory concentrations (MIC) of drug candidates and antibiotics against aerobic bacteria and yeasts. Minimal bactericidal and fungicidal concentrations (MBC and MFC, respectively) were also determined in connection with the MIC determinations. The results obtained were compared with those obtained using classical agar diffusion methodol
