The present work comprises the synthesis of enoxacin (Heno) complexes with various transition metals. Two types of complexes[M(eno)2(H2O)2]3H2O(M=CuII, NiII or MnII)and[M(eno)(H2O)2]Cl⋅4H2O  (M=FeIII)were obtained. The complexes were characterized by different physicochemical, spectroscopic, and elemental analysis. Results suggest that enoxacin interacts with the metals as a monoanionic bidentate ligand. These complexes were also tested for their antibacterial activity against eleven (11) different microorganisms, and the results were compared with the parent drug. Moreover all the metal complexes were also tested for their ability to scavenge reactive oxygen species where byMnIIandCuIIcomplexes exhibited potential to mediate anti-inflammatory response.

A series of novel 3-(6-substituted-1, 3-benzothiazole-2-yl)-2-[{(4-substituted phenyl) amino} methyl] quinazolines-4(3H)-ones were synthesized by treating 2-(chloromethyl)-3-(6-substituted-1, 3-benzothiazole-2-yl) quinazoline-4-(3H)-one (IIa-d) with various substituted amine. The compounds (IIa-d) prepared by treating 2-[(chloroacetyl) amino] benzoic acid with different 2-amino-6-substituted benzothiazole. Elemental analysis, IR,1HNMR and mass spectral data confirmed the structure of the newly synthesized compounds. Synthesized quinazolines-4-one derivative were investigated for their anti-inflammatory and antibacterial activity.

A Schiff base, 2-[4-(N,N-dimethylamino)benzylidene]benzoic acid has been synthesized by the condensation of 4-(N,N-dimethylamino)benzaldehyde and 2-amino-benzoic acid in 1:1 molar stoichiometry. The Schiff base complexes were synthesized from the chloride salts of Fe(II), Cu(II) and Zn(II) in ethanolic medium and elucidated by infrared spectroscopy, CHN elemental analysis, atomic absorption spectroscopy as well as conductivity and magnetic susceptibility measurements. The solubility and thermal stability were also determined. The metal(II) complexes are coloured solids that are soluble in DMF and DMSO. The melting point of the Schiff base was found to be 177 oC, while the complexes decompose within a temperature range of 202–261 oC suggestive of rather good thermal stability. The molar conductance values were low, indicating non-electrolytic nature of the complexes. Elemental analysis revealed that the stoichiometries of the synthesized complexes are of 1:2 metal-to-ligand ratio. All complexes were hydrated. The spectroscopic and magnetic susceptibility data revealed that the complexes possess four- coordinate distorted square planar stereochemistry, whereas the Schiff base behaves as monoanionic bidentate ligand with the nitrogen atom of the azomethine (C=N) and carboxylate oxygen (COO-) as donor sites. The Schiff base and its corresponding metal(II) complexes were assayed against a number of bacterial and fungal strains to evaluate their inhibitory potentials. All the complexes showed significant bactericidal and fungicidal activities against the tested organisms.

Two new ZnII(phen)2 complexes with trichloroacetate and acetate anions, [Zn(phen)2(CCl3COO)- (H2O)](ClO4) and [Zn(phen)2(CH3COO)](ClO4), have been synthesized and characterized by elemental analysis, IR, 1H NMR, 13C NMR spectroscopy. The single crystal X-ray data of these compounds show the Zn atoms to have six-coordinate geometry. From IR spectra and X-ray crystallography it is established that the coordination of the COO− group is different for trichloroacetate and acetate. The former acts as a monodentate whereas the latter acts as a bidentate ligand.

Chronic inflammatory diseases of various genesis are prevalent today. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain and inflammation, but their long-term use is associated with complications in the gastrointestinal tract, including peptic ulcers. We synthesized a molecule of sodium salt (4-О-β-glucopyranosyloxy)-benzoic acid. This substance has diuretic and anti-inflammatory activities. It should be noted that most of NSAIDs has analgesic effect. In this connection, the aim of this study was to evaluate the analgesic activity of sodium salt (4-О-β-glucopyranosyloxy)-benzoic acid. We studied analgesic effect in the test “acetic writhing”. Sodium salt (4-О-β-glucopyranosyloxy)-benzoic acid significantly reduces the number of writhing by 14 units during the experiment, as an alternative criterion percent of animals with analgesia was 42.6%. Thus, in the test "acetic writhing" revealed the presence of the analgesic activity have developed drug average severity.

The purpose of this work was to further expand the chemistry of mixed technetium nitrido-peroxo complexes, a still poorly explored class of compounds containing the Tc(VII) moiety, [99gTc][Tc(N)(O2)2]. A number of novel complexes of the formula [99gTc][Tc(N)(O2)2(L)] with bidentate ligands (L) (where L = deprotonated alanine, glycine, proline) were prepared by reacting a solution of nitrido-technetic(VI) acid with L in the presence of a source of H2O2. Alternatively, the complex [99gTc][Tc(N)(O2)2X]− (X = Cl, Br) was used as a precursor for substitution reactions where the halogenide ion was replaced by the bidentate ligand. The new complexes were characterized by elemental analysis and mass spectroscopy. The preparation of the analogous [99mTc][Tc(N)(O2)2] moiety, radiolabeled with the metastable isomer Tc-99m, was also studied at a no-carrier-added level, using S-methyl-N-methyl-dithiocarbazate as the donor of the nitrido nitrogen atoms.

Background: Plants still remain the prime source of drugs for the treatment of inflammation and can provide leads for the development of novel anti-inflammatory agents. Material and methods: An in vitro bioassay guide revealed that the 80% ethanol (EtOH) extract of the whole plant, Amomum tsao-ko (Zingiberaceae), displayed anti-inflammatory activity after assessing its effects on murine macrophage RAW 264.7 cells. Result: Phytochemical study of the 80% EtOH extract of Amomum tsao-ko led to the isolation of eight compounds: 4-hydroxy-3-methoxy-benzoic acid (1), meso-hannokinol (2), (+)-hannokinol (3), coumaric acid (4), 4-hydroxy-benzoic acid (5), (+)-epicatechin (6), (-)-catechin (7), and myrciaphenone A (8). The results indicated that two of the isolated components, (+)-epicatechin (6) and (-)-catechin (7), inhibited the production of nitric oxide (NO) significantly in lipopolysaccharide treated RAW 264.7 cells. Conclusion: LPS-induced interleukin tumor necrosis factor-alpha (TNF-), IL-1β and IL-10 production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that (+)-epicatechin (6) and (-)-catechin (7) reduced the expression of inducible nitric oxide synthase and inhibited nuclear localization of nuclear factor kappa-B (NF-κB).
