TY - JOUR T1 - Synthesis and Antimicrobial Evaluation of Novel 5,8-Dibromo-2-O/Ssubstituted-1,4-naphthoquinone Derivatives TT - Yeni 5,8-Dibromo-2-O/S-sübstitüe-1,4-naftakinon Türevlerinin Sentezi ve Antimikrobiyal Aktivitelerinin Değerlendirilmesi AU - Berkil Akar, Kıymet AU - Kılınç, Hasan PY - 2018 DA - August JF - Afyon Kocatepe Üniversitesi Fen Ve Mühendislik Bilimleri Dergisi PB - Afyon Kocatepe Üniversitesi WT - DergiPark SN - 2149-3367 SP - 451 EP - 457 VL - 18 IS - 2 LA - en AB - Novel bromo- and O/S-substituted-1,4-naphthoquninones (3a-3i) were synthesized via nucleophilic substitution reactions from 2,5,8-tribromo-1,4-naphthoquinone (1). Antimicrobial evaluation of the newly synthesized derivatives was performed using agar spot method. Compounds 3a, 3b, and 3c exhibited the greatest activity with MIC value of 61,25 μg/mL against P. vulgaris, B. cereus and B.subutilis, and B.cereus, respectively. Results revealed that compound 3c has notable activity against all tested microorganisms. KW - 1 KW - 4-Naphthoquinone KW - Nucleophilic KW - substitution KW - Antimicrobial activity N2 - 2,5,8-Tribromo-l,4-naftokinon’dan (1) nükleofilik sübstitüsyon reaksiyonları ile yeni bromo- ve O/Ssübstitüe-1,4-naftokininon (3a-3i) türevleri sentezlendi. Yeni sentezlenen türevlerin antimikrobiyal olarak incelenmesi agar spot yöntemi kullanılarak gerçekleştirildi. Bileşik 3a, 3b ve 3c sırasıyla P. vulgaris, B. cereus ve B.subutilis, ve B.cereus'a karşı 61,25 ug/mL’lik MIC değeri ile en büyük aktivite sergiledi. Sonuçlar, bileşik 3c'nin test edilen tüm mikroorganizmalara karşı belirgin etkinliğe sahip olduğunu ortaya koymuştur.
