Substituted salicylaldehydes are potent antibacterial and antifungal agents and may have chemotherapeutic potential. In the clinical setting, the minimal inhibitory concentration (MIC) as well as the minimal bactericidal and fungicidal concentrations (MBC and MFC, respectively) are of fundamental interest. Therefore
