Eight new Schiff bases of 5-nitro and 5-bromo-substituted 1,10-phenanthroline-2,9-dicarboxaldehydes with sulfur-containing amines, thiosemicarbazide, S-alkyl/aryl dithiocarbazates and 2-mercaptoaniline have been synth... Eight new Schiff bases of 5-nitro and 5-bromo-substituted 1,10-phenanthroline-2,9-dicarboxaldehydes with sulfur-containing amines, thiosemicarbazide, S-alkyl/aryl dithiocarbazates and 2-mercaptoaniline have been synthesized and characterized by a variety of spectroscopic methods. The condensation reactions of the dialdehydes with the amines were carried out both in the presence and absence of conc. sulfuric acid. A significant increase in yield of the Schiff bases was observed when the reactions were carried out in the presence of sulfuric acid. 展开更多

Schiff bases are known to possess anticancer, antibacterial, antifungal, antitubercular, anti-inflammatory, antimicrobial and antimalarial properties. In this paper antibacterial studies against variety of plants and human pathogenic bacteria with eight newly synthesized Schiff bases and several intermediate silyl compounds have been reported. The antibacterial activities of the synthesized compounds were primarily determined by paper disc diffusion method. The minimum inhibitory concentration (MIC) of each compound was also determined by tube dilution process. Seven different human pathogenic bacteria and eighteen different plant pathogenic bacteria were used for the antibacterial activity studies. While all synthesized compounds have shown significant antibacterial activity, one intermediate silyl compound has shown remarkably high antibacterial property. 5-substituted derivatives have shown relatively higher activity than non-substituted compounds. Polar substituent which increases hydrophilicity may have a positive impact on the antibacterial property. 展开更多

Three new coordination polymers,namely [Zn(FDA)(phen)(H2O)·H2O]n(1),[Cd(HFDA)(phen)2(NO3)](2) and [Cd(FDA)(phen)]n(3)(H2FDA = 2,5-furandicarboxylic acid,phen = 1,10-phenanthroline) have be... Three new coordination polymers,namely [Zn(FDA)(phen)(H2O)·H2O]n(1),[Cd(HFDA)(phen)2(NO3)](2) and [Cd(FDA)(phen)]n(3)(H2FDA = 2,5-furandicarboxylic acid,phen = 1,10-phenanthroline) have been synthesized by the solvothermal method and characterized by elemental analysis,IR,powder X-ray diffraction,thermogravimetric analysis and X-ray single-crystal diffraction analysis.For 1,the neighboring Zn^2+ ions are bridged by FDA2-as linkers to form one-dimensional(1D) chains,and phen ligands are as the terminal ligands.Furthermore,the 1D chains are packed into a three-dimensional(3D) supramolecular structure through hydrogen bonds and π-π interactions.For 2,the H2FDA ligand is partial deprotonation,which is a rare phenomenon among other coordination polymers based on H2FDA.Under the synergetic effect of phen ligands and the partial deprotonation of H2FDA,the structure of 2 is discrete.For 3,the Cd^2+ ions are linked by two carboxylates of FDA^2-ligand to give rise to 1 D zig-zag chains,and phen ligands chelate the Cd^2+ ions like 1.In addition,solid-state luminescent spectra of three coordination polymers were also studied at room temperature. 展开更多

A new complex {[Mn2(IP)2(1,4-bdc)2]·H2O}n(1)(IP = 1H-imidazo[4,5-f][1,10]-phenanthroline, 1,4-H2 bdc = 1,4-benzendicarboxylic acid), have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group Cc with a = 20.326(2), b = 24.249(2), c = 7.621(1)A, β = 108.546(6), V = 3561.2(7)A3, Z = 4, Dc = 1.672 g/cm^3, μ = 0.785 mm^-1, F(000) = 1824, S = 1.067, the final R = 0.0299 and wR = 0.0752. Compound 1 possesses a 2D structural motif, in which two crystallographically independent 1,4-bdc dianions adopt the alternative mode of mixed bis(bidentate) and monodentate-bidentate coordination modes to bridge neighboring Mn(II) centers. And the 2D layers are linked up by hydrogen bonding and π···π stacking interactions to form a 3D network. The title compound has good thermal stability and exhibits photoluminescent emission maximum at 518 nm. 展开更多

Here we have synthesized cancer targeting drug delivery system that contains β-cyclodextrin as a drug carrier and folic acid as a targeting ligand. Folic acid was selected as a cancer targeting ligand because folic acid receptors are highly expressed in a variety of tumor types. β-cyclodextrin and folic acid were connected through a linker [1,10-phenanthroline or 5-(hydroxymethyl) furfural]. β-cyclodextrin and folic acid were attached to the linker by formation of Schiffbase and ester, respectively. Our targeted synthetic products were confirmed by NMR, Mass and IR spectroscopy. We anticipate that our synthetic products can confer cancer cell-specific drug delivery as well as desired properties such as nanoparticle formation. 展开更多
