Microwave-assisted preparation of azachalcones and their N-alkyl derivatives with antimicrobial activities
Usta, Asu; Öztürk, Elif; Beriş, Fatih Şaban (Taylor & Francis Ltd, 2014)Two new azachalcones were prepared by both Claisen-Schmidt condensation and a simple environmentally trendy microwave-assisted method. Ten new N-alkyl (C-6,C-8,C-10,C-12,C-14)-substituted azachalconium bromides (3a-e, 4a-e) ... -
New pyrimidine-N-β-D-glucosides: synthesis, biological evaluation, and molecular docking investigations
Kahriman, Nuran; Peker, Kıvanç; Serdaroğlu, Vildan; Aydın, Ali; Türkmenoğlu, Burçin; Usta, Asu; Yaylı, Nurettin (Scientific Technical Research Council Turkey, TÜBİTAK, 2023)In this study, syntheses of new pyrimidine-coupled N-beta-glucosides and tetra-O-acetyl derivatives were carried out. All glycoconjugates were investigated in comparison with known chemotherapeutic agents in terms of their ... -
Novel 2-amino-4-aryl-6-pyridopyrimidines and N-alkyl derivatives: Synthesis, characterization and investigation of anticancer, antibacterial activities and DNA/BSA binding affinities
Kahriman, Nuran; Peker, Kıvanç; Serdaroğlu, Vildan; Aydın, Ali; Usta, Asu; Fandaklı, Seda; Yaylı, Nurettin (Academic Press Inc Elsevier Science, 2020)A series of new 2-amino-4-aryl-6-pyridopyrimidines, and their N-alkyl bromide derivatives were designed and synthesized by employing methyl substituted azachalcones. These novel compounds were evaluated and compared to the ... -
Synthesis and antimicrobial properties of N-substituted derivatives of (E)-2 ',3 ''-thiazachalcones
Usta, Asu; Taşkıran, Hacer (Walter de Gruyter Gmbh, 2015)N-alkyl substituted 2',3 ''-thiazachalcones {3-[(1E)-3-(4-methylthiophene-2-yl)-3-oxoprop-1-en-1-yl]-1-alkyl (C-5-12,C-14) pyridinium bromides} were synthesized by a two-step reaction. the newly synthesized compounds were ... -
