    Nucleophilic substitution reactions of 1,4-naphthoquinone and biologic properties of novel S-, S,S-, N-, and N,S-substituted 1,4-naphthoquinone derivatives
    (Springer Birkhauser, 2014) Ibis, Cemil; Tuyun, Amac Fatih; Bahar, Hakan; Ayla, Sibel Sahinler; Stasevych, Maryna V.; Musyanovych, Rostyslav Ya.; Komarovska-Porokhnyavets, Olena
    A novel series of S-, S,S-, N- and N,S-substituted 1,4-naphthoquinone derivatives were synthesized and evaluated for their antibacterial and antifungal activity. Among the synthesized compounds especially 10a and 11b have been discovered as an antibacterial or antifungal agents, and 15f is the most effective compound against M. luteum as potent antifungal. The structures of the novel products were characterized by micro analysis, UV/Vis, H-1 NMR, C-13 NMR, and MS. The electrochemical properties of some of the novel 1,4-naphthoquinone derivatives were also investigated by cyclic voltammetry.

    Synthesis and Antibacterial and Antifungal Properties of Novel S-, N-, N,S-, and S,O-Substituted 1,4-Naphthoquinone Derivatives
    (Taylor & Francis Ltd, 2013) Ibis, Cemil; Tuyun, Amac Fatih; Ozsoy-Gunes, Zeliha; Ayla, Sibel Sahinler; Stasevych, Maryna V.; Musyanovych, Rostyslav Ya; Komarovska-Porokhnyavets, Olena
    A novel series of substituted 1,4-naphthoquinone derivatives were synthesized and evaluated for their antibacterial and antifungal activity. The structures of the novel products were characterized by spectroscopic methods. Among the tested compounds, 2,2,3,3-alkoxy substituted naphthoquinones, S,O-substituted naphthoquinone, and N,S-substituted naphthoquinone derivatives are the most potent antifungals against C. tenuis. 2,3-Thio-2,3-alkoxy substituted naphthoquinones are the most effective antifungal compounds against A. niger.

    Synthesis of novel 1,4-naphthoquinone derivatives: antibacterial and antifungal agents
    (Springer Birkhauser, 2013) Ibis, Cemil; Tuyun, Amac Fatih; Bahar, Hakan; Ayla, Sibel Sahinler; Stasevych, Maryna V.; Musyanovych, Rostyslav Ya.; Komarovska-Porokhnyavets, Olena
    A novel series of substituted 1,4-naphthoquinone derivatives was synthesized and evaluated for antibacterial and antifungal activity. The structures of the novel products were characterized by spectroscopic methods. Among the tested compounds, 3a and 9 are the most effective compounds against M. luteum as potent antibacterial and C. tenuis and A. niger as potent antifungal. These two compounds are promising as biologically active compounds.
