Potansiyel Antimikrobiyal Ajanlar Olarak Yeni 5,8-Dibromo-2-N-Sübstitüe-1,4-Naftokinon Türevlerinin Sentezi ve Biyolojik Değerlendirmesi

Yedi adet 5,8-dibromo-2-N-sübstitüe-1,4-naftakinon türevi sentezlenmiş ve bu bileşiklerin in vitro antimikrobiyal aktiviteleri test edilmiştir. Elde edilen sonuçlar 2-N-sübstite-1,4-naftakinonların yüksek antimikrobiyal etkinliğe sahip olduklarını göstermektedir. Bileşiklerin difüzyon kapasitesi de antimikrobiyal aktivitelerin belirlenmesinde önem taşımaktadır; Sonuçlar 2c, 2f ve 2g bileşiklerinin gelecekteki çalışmalar için umut verici bileşikler olduklarını ortaya koymuştur.

Synthesis and Biological Evaluation of Novel 5,8-Dibromo-2-N-substituted-1,4-Naphthoquinone Derivatives as Potential Antimicrobial Agents

The seven 5,8-dibromo-2-N-substituted-1,4-naphthoquinonederivatives have been synthesized and tested for their in vitro antimicrobialactivities. The results suggest that the synthesized 2-N-substituted-1,4-naphthoquinoneshave high antimicrobial activity. The diffusion capacities of the compounds arealso important for the determination of the antimicrobial activities; 2c, 2f and 2g have beenshown to be promising compounds for future studies.
