Synthesis, Characterization and Antibacterial Study of Some 3d-Metal Complexes of Paracetamol and 1,10- Phenanthroline

Novel complexes of Co(II), Ni(II) and Cu(II) with paracetamol and 1,10-phenanthroline have been synthesized and characterized using infrared spectroscopy, mass spectrometry, electronic absorbance, melting point and conductivity measurements. The two ligands have been found to act as bidentate chelating agents. Paracetamol coordinates through the carbonyl group and nitrogen atom of amide group, while1,10-phenanthroline coordinates through the two nitrogen atoms. Based on magnetic moment and electronic spectral studies, an octahedral geometry has been assigned for the complexes. Antibacterial screening of the complexes against some gram positive and negative bacteria was tested.

Preparation and Properties of a Novel Semi-IPN Slow-Release Fertilizer with the Function of Water Retention

A new semi-interpenetrating polymer network (semi-IPN) slow-release fertilizer (SISRF) with water absorbency, based on the kaolin-g-poly(acrylic acid-co-acrylic amide) (kaolin-g-P(AA-co-AM)) network and linear urea-formaldehyde oligomers (UF), was prepared by solution polymerization. Nutrients phosphorus and potassium were supplied by adding dipotassium hydrogen phosphate during the preparation process. The structure and properties of SISRF were characterized by various characterization methods. SISRF showed excellent water absorbency of 68 g g(-1) in tap water. The slow-release behavior of nutrients and- water-retention capacity of SISRF were also measured. Meanwhile, the swelling kinetics was well described by a pseudo-second-order kinetics model. Results suggested the formation of SISRF with simultaneously good slow-release and retention capacity, which was expected to apply in modern agriculture and horticulture.

TBD-Catalyzed Ring-Opening Polymerization of Alkyl-Substituted Morpholine-2,5-Dione Derivatives

In a two-step synthesis, five different alkyl-substituted morpholine-2,5-dione monomers were synthesized from the natural amino acids glycine, alanine, valine, leucine, and isoleucine. The heterocyclic compounds crystallize in a boat-like conformation and are polymerized via 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)-catalyzed ring-opening polymerization (ROP) in tetrahydrofuran. Well-defined polymers could be obtained from the monomers based on valine, leucine, and isoleucine at a feed ratio of M/I/TBD = 100/1/0.5. Kinetic studies of the ROP reveal that the molar masses and dispersities (D < 1.2) could be well controlled, as confirmed by size exclusion chromatography and H-1 NMR spectroscopy. At conversions above 50%, the polymerization rate decreases and the dispersity slightly increases, presumably due to transesterification. Matrix-assisted laser desorption time-of-flight mass spectrometry indicates the presence of polymer chains with alpha-end groups derived from the initiator. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Human mass balance study and metabolite profiling of C-14-niraparib, a novel poly(ADP-Ribose) polymerase (PARP)-1 and PARP-2 inhibitor, in patients with advanced cancer

Niraparib is an investigational oral, once daily, selective poly(ADP-Ribose) polymerase (PARP)-1 and PARP-2 inhibitor. In the pivotal Phase 3 NOVA/ENGOT/OV16 study, niraparib met its primary endpoint of improving progression-free survival (PFS) for adult patients with recurrent, platinum sensitive, ovarian, fallopian tube, or primary peritoneal cancer in complete or partial response to platinum-based chemotherapy. Significant improvements in PFS were seen in all patient cohorts regardless of biomarker status. This study evaluates the absorption, metabolism and excretion (AME) of C-14-niraparib, administered to six patients as a single oral dose of 300 mg with a radioactivity of 100 mu Ci. Total radioactivity (TRA) in whole blood, plasma, urine and faeces was measured using liquid scintillation counting (LSC) to obtain the mass balance of niraparib. Moreover, metabolite profiling was performed on selected plasma, urine and faeces samples using liquid chromatography – tandem mass spectrometry (LC-MS/MS) coupled to off-line LSC. Mean TRA recovered over 504 h was 47.5% in urine and 38.8% in faeces, indicating that both renal and hepatic pathways are comparably involved in excretion of niraparib and its metabolites. The elimination of C-14-radioactivity was slow, with t(1/2) in plasma on average 92.5 h. Oral absorption of C-14-niraparib was rapid, with niraparib concentrations peaking at 2.49 h, and reaching a mean maximum concentration of 540 ng/mL. Two major metabolites were found: the known metabolite M1 (amide hydrolysed niraparib) and the glucuronide of M1. Based on this study it was shown that niraparib undergoes hydrolytic, and conjugative metabolic conversions, with the oxidative pathway being minimal.

Optimization of Hexavalent Chromium Biosorption by Shewanella putrefaciens Using the Box-Behnken Design

Cr(VI) is a ubiquitous pollutant that poses a serious threat to human health. Recently, the use of microorganisms to adsorb heavy metals has attracted research attention. However, there are few studies on the biosorption of Cr(VI) by Shewanella putrefaciens, which is a metal-reducing bacterium. In this paper, single-factor experiments were designed to investigate the effect of hexavalent chromium by Shewanella putrefaciens, and response surface methodology (RSM) based on the Box-Behnken design (BBD) was performed to study the Cr(VI) biosorption behavior of Shewanella putrefaciens. The coefficient of determination (R-2 = 0.811 for Cr(VI)) and probability value (P < 0.05) demonstrated significance for the obtained regression model. The results showed that the model was suitable for experimental data, and the maximum Cr(VI) removal efficiency by Shewanella putrefaciens was 85.68% under the optimum conditions of a contact time of 16.57 h, pH value of 8, and biomass dosage of 0.42 g/L, which were verified by additional experiments. ANOVA and 3D response graph analysis showed that the variables with significant influences were pH and temperature. In addition, scanning electron microscopy (SEM) results demonstrated that after biosorption of Cr(VI) by Shewanella putrefaciens, granular complexes attached to rough cell surfaces were observed. Furthermore, Fourier transform infrared spectroscopy (FT-IR) analysis showed that the distribution of Cr(VI) on the cell surface was related to the carboxyl, ether, amide, hydroxyl, and phosphoric acid groups of Shewanella putrefaciens. This study is useful to explore the process and mechanism of heavy metal adsorption by Shewanella putrefaciens and provide new ideas for the microbial remediation of metal pollution in water.

Gly-His-Thr-Asp-Amide, an Insulin-Activating Peptide from the Human Pancreas Is a Strong Cu(II) but a Weak Zn(II) Chelator

The Cu(II) and Zn(II) binding abilities of Gly-His-Thr-Asp-amide (GHTD-am), a tetrapeptide coreleased from the pancreas along with insulin, were studied using UV-vis and circular dichroism spectroscopies, potentiometry, and calorimetry. GHTD-am is a very strong Cu(II) chelator, forming a three-nitrogen complex with a conditional affinity constant K-c at pH 7.4 of 4.5 X 10(12) M-1. The fourth coordination site can be occupied by a solvent molecule or a ternary ligand, such as imidazole, with K-c on the order of several hundred reciprocal molar. The Zn(II) binding ability of GHTD-am is relatively weak, with K-c values at pH 7.4 of 3.0 X 10(4) and 2.0 x 10(3) for the first and second GHTD-am molecule coordinated, respectively. These results are discussed in light of the modes of interactions of Zn(II) and Cu(II) ions with insulin. A direct effect of GHTD-am on the Zn(II) interactions with insulin is unlikely, but its Cu(II) complex may have a biological relevance because of its high affinity and ability to form ternary complexes.
