    Crystal and molecular structure of 3-phenyl-4-(p-chlorobenzylamino)-4,5-dihydro-1-H-1,2,4-triazol-5-on
    (Wiley-V C H Verlag Gmbh, 2004) Yilmaz, V.T.; Agar, E.; Guven, K.; Kahveci, B.; Sasmaz, S.
    The structure of the title compound, C15H13N4OCl was determined by single crystal X-ray diffraction technique. The structure consists of a p-chlorobenzylamino moiety and triazol and phenyl rings. The title compound crystallizes in the monoclinic space group P2(1)/c with a = 14.368(3), b = 6.255(3), c = 17.631(3) Angstrom, beta = 113.24(3)degrees, Z = 4, V = 1455.8(8) Angstrom(3) and D-x = 1.372 gcm(-3). The structure was solved by direct methods and refined by full-matrix least-squares method (R=0.0477). The dihedral angle between the triazole moiety and the phenyl ring is 28.8(3)degrees. The molecular packing is stabilized by N-(HN)-N-... and N-(HO)-O-... types of inter molecular hydrogen bonds.

    Novel Phthalocyanines Containing Guaiacol Azo Dyes: Synhthesis, Antioxidant, Antibacterial, and Anticancer Activity
    (Pleiades Publishing Inc, 2018) Kantar, C.; Kaya, B.; Turk, M.; Sasmaz, S.
    In an attempt to understand the antibacterial, antioxidant, and anticancer properties of phthalocyanines containing azo dye, new metallophthalocyanines (M: Mn, Co, Zn) substituted with guaiacol azo dyes are described. The high DPPH scavenging and ferrous ion chelating activity are obtained from almost all compounds. All compounds exhibit a poor antibacterial activity against the studied bacteria. Cytotoxicity, apoptotic and necrotic effects are examined on human breast cancer cells (MCF-7) and fibroblast cells. It is determined that methoxy groups at newly synthesized compounds increase the antioxidant property but decrease other antibacterial and anticancer properties.
