Abstract

Although the resistance is commonly known as bacterial, this problem is not related only to the domain of bacteria. The occurrence of resistant mutants of fungi is also observed. Another problem with some known antifungal drugs is that only topical applications are used due to their toxicity or limited bioavailability [1]. Thus this situation justifies the urgency to design and discover not only antibacterial but also antifungal new drugs [2].

Styrylquinoline derivatives structurally related to dichloroquinoline (e.g. chloroxine) are potential antimicrobial compounds. These derivatives were studied by Cieslik et al. [3] recently. Some of these structures expressed antifungal activity comparable with or higher than the standard fluconazole. The antibacterial effect especially against Staphylococcus strains was observed as well [3]. Based on these results, new structures were synthesized and evaluated with respect to their activity, what is presented in this work. New compounds were tested against Candida strains for their antifungal effect and against Staphylococcus and Enteroccocus strains for their antibacterial activity. Antibacterial effects were tested also against methicillin-resistant staphylococci and vancomycin-resistant enterococci.
