  Synthesis, spectral and antimicrobial activity of Zn(II) complexes with Schiff bases derived from 2-hydrazino-5-[substituted phenyl]-1,3,4-thiadiazole and benzaldehyde/2-hydroxyacetophenone/indoline-2,3-dione

  摘要：

  Zn(II) complexes have been synthesized by reacting zinc acetate with Schiff bases derived from 2-hydrazino-5-[substituted phenyl]-1,3,4-thiadiazole and 2-hydroxyacetophenone/benzaldehyde/indoline-2, 3-dione. All these complexes are soluble in DMF and DMSO; low molar conductance values indicate that they are non electrolytes. Elemental analyses suggest that the complexes have 1:2 metal to ligands stoichiometry of the types [ZnL2(H2O)(2)](L = monoanionic Schiff bases derived from 2-hydrazino-5-[substituted phenyl]-1,3,4-thiadiazole and 2-hydroxyacetophenone/indoline-2,3-dione) [ZnL2'(OOCCH3)(2)(H2O)(2)] (L' = neutral Schiff bases derived from 2-hydrazino-5-[substituted phenyl]-1,3,4-thiadiazole and benzaldehyde), and they were characterized by IR, H-1 NMR, and C-13 NMR. Particle sizes of synthesized compounds were measured with dynamic light scattering (DLS) analyser which indicates that particle diameter are of the range ca. 100-200 nm. All these Schiff bases and their complexes have also been screened for their antibacterial (Bacillus subtilis (B. subtilis), Escherichia colt (E. coli) and antifungal activities (Colletotrichum falcatum (C. falcatum), Aspergillus niger (A. niger), Fusarium oxysporium (F. oxysporium) Curvularia pallescence (C pallescence). The antimicrobial activities have shown that upon complexation the activity increases. (C) 2013 Elsevier B.V. All rights reserved.

  Development of 3,5-Dinitrobenzylsulfanyl-1,3,4-oxadiazoles and Thiadiazoles as Selective Antitubercular Agents Active Against Replicating and Nonreplicating Mycobacterium tuberculosis

  摘要：

  Herein, we report the discovery and structure activity relationships of 5-substituted-2-[(3,5-dinitrobenzyl)-sulfanyl]-1,3,4-oxadiazoles and 1,3,4-thiadiazoles as a new class of antituberculosis agents. The majority of these compounds exhibited outstanding in vitro activity against Mycobacterium tuberculosis CNCTC My 331/88 and six multidrug-resistant clinically isolated strains of M. tuberculosis, with minimum inhibitory concentration values as low as 0.03 mu M (0.011-0.026 mu g/mL). The investigated compounds had a highly selective antimycobacterial effect because they showed no activity against the other bacteria or fungi tested in this study. Furthermore, the investigated compounds exhibited low in vitro toxicities in four proliferating mammalian cell lines and in isolated primary human hepatocytes. Several in vitro genotoxicity assays indicated that the selected compounds have no mutagenic activity. The oxadiazole and thiadiazole derivatives with the most favorable activity/toxicity profiles also showed potency comparable to that of rifampicin against the nonreplicating streptomycin-starved M. tuberculosis 18b-Lux strain, and therefore, these derivatives, are of particular interest.

  A series of novel nopol derivatives containing 1,3,4-thiadiazole–thioether moiety were synthesized from β-pinene, which is a natural, abundant and renewable biomass resource. Their structures were characterized by FT-IR, 1H NMR, 13C NMR, ESI–MS and elemental analysis. In vitro antifungal activity of the target compounds was preliminarily evaluated against eight tested plant pathogens, including Fusarium oxysporum f. sp. cucumerinum, Cercospora arachidicola, Physalospora piricola, Alternaria solani, Gibberella zeae, Rhizoeotnia solani, Bipolaris maydis and Colleterichum orbicalare. The bioassay results revealed that, at the concentration of 50 μg/mL, all the target compounds showed certain inhibition activity against the eight tested fungi. Compounds 5f (R = m–OCH3), 5i (R = m–F) and 5r (R = m–I) had excellent inhibition rates of 77.8%, 88.9% and 77.8%, respectively, against P. piricola, showing much better antifungal activity than that of the positive control chlorothalonil. Meanwhile, compound 5 m (R = p–Cl) displayed antifungal activity of 80.7% against R. solani. Furthermore, the analysis of three-dimensional quantitative structure–activity relationship (3D-QSAR) was performed for the relationship between the structures of the target compounds and their antifungal activity against P. piricola by CoMFA method. A reasonable CoMFA model (n = 6; q2 = 0.597; r2 = 0.985) was established.
