  Synthesis, DNA Binding, and Antimicrobial Activity of Base-Catalyzed 2-Phenyl-3-pyrido[3,2][1,3,4]thiadiazolo [3,2]quinoline Derivatives

  摘要：

  A series of novel 3-{[(5-phenyl-1,3,4-thiadiazol-2-yl)imino] methyl}quinoline-2-thione (2a-c) and 2-phenyl-3-pyrido[3,2][1,3,4]thiadiazolo[3,2]quinoline derivatives (3a-c) were prepared by a facile synthetic method using an anhydrous potassium carbonate catalyst. The newly synthesized heterocyles were characterized by elemental analysis, FT-IR, H-1-NMR, and mass spectral data. The selected compounds were studied for interaction with calf thymus-DNA(CT-DNA) by electronic spectra and viscosity measurements, as well as thermal denaturation studies. Upon binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. The binding constant (K-b) observed value of 8.4 x 10(5) M-1 for (2a) and 8.2 x 10(5) M-1 for (3a) suggested that compound (2a) binds more avidly to CT-DNA than compound (3a). The increasing viscosity of sonicated rod-like DNA fragments and the melting temperature of DNA, in the presence of compound solutions, support the binding mode. The synthesized derivatives have been screened for antibacterial and antifungal activities.
