Multiple coordination modes of a new ditopic bis(pyrazolyl)methane-based ligand

A new ditopic ligand, N-(2,2-bis(pyrazolyl)ethyl)-2,2-bis(pyrazolyl)acetamide ((pz)(2)CH-C(O)-NH-CH2-CH(pz)(2), L4Pz, pz = pyrazolyl ring), comprising two bis(pyrazolyl)methane donor groups linked via an amide bridge, has been prepared from the reaction of HOOCCH(pz)(2) and H2NCH2CH(pz)(2). The ligand coordinates to various metallic salts (i.e. AgO3SCF3, PdCl2, Re(CO)(5)Br, and Fe(BF4)(2)), in either a (2)–(2) or a (3)–(2) fashion, depending on the coordination preferences of the metallic center. These compounds were characterized by NMR, UV-Vis and IR spectroscopy, and in solid state by single crystal X-ray diffraction. In the case of silver(i), a mono-dimensional coordination polymer was obtained, while the others were found to be discrete complexes. The synthesis and characterization of a heterobimetallic complex is also described. In solid state, all compounds are associated into supramolecular architectures via hydrogen bonding and pyrazolyl embrace interactions.

Sodium caseinate films modified using halloysite: Physicochemical characterization and drug permeability studies

Modification of sodium caseinate (SC) films by adding halloysite (HS) was investigated in this study. SC films with HS added in different ratios were prepared, and the physicochemical properties and drug permeability of the films were characterized. Acetaminophen was used as a model drug, and parabens served to evaluate the effect of the molecular weight of permeants through the films. This study revealed that SC could interact with HS through hydrogen bonding between the amine and amide groups of SC and the hydroxyl groups on the inner or outer tubular HS. The SC-HS films presented as continuous sheets and had a similar transparency as the SC films. The thermal stability of the SC films could be enhanced by adding HS. Incorporation of HS caused a reduction in puncture strength and elongation of the dry SC films, whereas strength enhancement of the we SC-HS films in acidic medium was found. The SC-HS films had lower water uptake and delayed drug permeation across the films in acidic medium. Moreover, the drug permeations across the SC and SC-HS films were dependent on the molecular weight or alkyl chain of parabens that impacted drug diffusion and partition processes through the films. The new knowledge obtained can be helpful for the development of film coating material based on SC-HS composites for modified-release tablets.

Insights from quantum chemical calculations into inner and outer-sphere complexation of plutonium(IV) by monoamide and carbamide extractants

The strong influence of the structure of amide derivatives on their extraction properties has been demonstrated in several studies in the literature. To investigate and rationalize the influence of the nature and length of the monoamide alkyl chains on Pu(IV) extraction/complexation, a theoretical study was performed using the Density Functional Theory (DFT) method in the scalar relativistic framework. For that, the geometries for the inner/outer-sphere complexes and interaction energies of [Pu(NO3)(4)] and [Pu(NO3)(6)](2-) with different ligands have been calculated. For both inner and outer-sphere complexes, it is found that the introduction of a bulky alkyl group on the carbonyl side strongly diminishes the complexation energy. This is fully consistent with monamide extraction properties. The influence of the bulkiness of the alkyl group is as or even more important for outer than for inner-sphere interactions. This result was unexpected when considering that there are less flexibility and stronger steric constraints in the inner sphere compared to the outer one. However, this can be attributed to specific electrostatic interactions between the two outer-sphere amide ligands and two nitrate ions of [Pu(NO3)(6)](2-). By increasing the polarity of the solution, such interactions diminish and the outer-sphere ligands move away from [Pu(NO3)(6)](2-). Consequently, the solvent effects were found to be very significant for outer-sphere complexation while rather small for inner-sphere complexation. This gives the key possibility to tune the substituent effect by changing the polarity of the solution. As for carbamide ligands, it was found that the weak interactions (dispersion) have remarkable effects on both inner and outer-sphere complexations.

Metalation behavior of a bis-saturated NHC ligand with a flexible m-xylyl linker

Saturated N-heterocyclic carbenes have unique ligand properties that differ even from their unsaturated analogs. While the unsaturated version has been extensively used in multidentate ligand scaffolds, the incorporation of the saturated version is less common. Here we report the straightforward synthesis of a new bis-saturated N-heterocyclic carbene ligand wherein the carbene moieties are linked by a flexible meta-xylyl unit. Carbene metal complexes of the proligand can be generated by direct metalation, transmetallation or base assisted metalation all of which lead to monodentate coordination modes of silver or iridium. Attempts at direct metalation using zirconium tetrakis-dimethylamide did not lead to complex formation but to the chloroform adduct or amide addition product. As yet, a method to generate pincer complexes from this ligand has not been found. The flexible nature of the xylyl linker as well as the higher sigma-bacisity and -acidity are postulated to contribute to these results.

Antiproliferative effect, alteration of cancer cell cycle progression and potential MET kinase inhibition induced by 3,4-dihydropyrimidin-2 (1H)-one C5 amide derivatives

Cancer continues to be the second leading cause of death worldwide. Discovery of novel therapeutic agents has crucial importance for improvement of our medical management capabilities. Dysregulation of the MET receptor tyrosine kinase pathway plays an important role in cancer progression, making this receptor an attractive molecular target for anticancer drug discovery. In this study, twenty-seven 3,4-dihydropyrimidin-2(1H)-one C5 amide derivatives were synthesized and their cancer cell growth inhibitory activity was examined against MCF-7, HT-29 and MOLT-4 cells and also NIH/3T3 non-cancer cells by MTT assay. The antipmliferative effect of the most potent derivatives were tested against MET-dependent EBC-1 and MKN-45, lung and gastric cancer cell lines, respectively. MET kinase inhibition was measured by a Homogenous Time Resolved Fluorescence (HTRF) Assay. The influence of the test compounds on cell cycle was examined by RNase/PI flow cytometric assay. A number of compounds exhibited considerable antiproliferative effects against breast and colon cancer and leukemia cell lines, relatively sparing non-cancer cells. Some derivatives bearing benzothiazolyl carboxamide moiety at C5 position (15, 21, 23, 31, and 37) showed the highest activities with IC50 values as low as 10.9 mu M. These compounds showed antiproliferative effects also against MET-amplified cells and dose-dependently inhibited MET kinase activity. They also induced G0/G1 cell cycle arrest at lower doses and apoptosis at higher doses. Molecular docking and dynamics simulation studies confirmed the interaction of compound 23 with the active site of the MET receptor. These findings demonstrate that 3,4-dihydropyrimidin-2(1H)-one analogues may represent promising targeted anticancer agents.

Induction of Caspase-Mediated Apoptosis in HepG2 Liver Carcinoma Cells Using Mutagen-Antioxidant Conjugated Self-Assembled Novel Carbazole Nanoparticles and In Silico Modeling Studies

In this study, novel self-assembled carbazole-thiooctanoic acid nanoparticles (CTNs) were synthesized from amino carbazole (a mutagen) and thiooctanoic acid (an antioxidant). The nanoparticles were characterized using hyperspectral techniques. Then, the antiproliferative potential of CTNs was determined in HepG2 liver carcinoma cells. This study employed a solvent-antisolvent interaction method to synthesize a spherical CTN of size less than 50 nm. Moreover, CT was subsequently capped to gold nanoparticles (AuNPs) in the additional comparative studies. The CT derivative was synthesized from carbazole and lipoic acid by the amide bond formation reaction using a coupling agent. Furthermore, it was characterized using infrared (IR), H-1 nuclear magnetic resonance, dynamic light scattering (DLS), and transmission electron microscopy techniques. The CT-capped gold nanoparticles (CTAuNPs) were prepared from CT, chloroauric acid, and NaBH4. The CTAuNPs were characterized using ultraviolet-visible, high-resolution TEM, DLS, and Fourier transform IR techniques. The cytotoxicity and apoptosis-inducing ability of both nanoparticles were determined in HepG2 cells. The results demonstrate that CTNs exhibit antiproliferative activity in the cancerous HepG2 cells. Moreover, molecular docking and molecular dynamics studies were conducted to explore the therapeutic potential of CT against human EGFR suppressor protein to gain more insights into the binding mode of the CT, which may show a significant role in anticancer therapy.

Effects of acute exposure to chlorpyrifos on cholinergic and non-cholinergic targets in normal and high-fat fed male C57BL/6J mice

The prevalence of obesity is increasing at an alarming rate in the United States with 36.5% of adults being classified as obese. Compared to normal individuals, obese individuals have noted pathophysiological alterations which may alter the toxicokinetics of xenobiotics and therefore alter their toxicities. However, the effects of obesity on the toxicity of many widely utilized pesticides has not been established. Therefore, the present study was designed to determine if the obese phenotype altered the toxicity of the most widely used organophosphate (OP) insecticide, chlorpyrifos (CPS). Male C57BL/6J mice were fed normal or high-fat diet for 4 weeks and administered a single dose of vehicle or CPS (2.0 mg/kg; oral gavage) to assess cholinergic (acetylcholinesterase activities) and non-cholinergic (carboxylesterase and endocannabinoid hydrolysis) endpoints. Exposure to CPS significantly decreased red blood cell acetylcholinesterase (AChE) activity, but not brain AChE activity, in both diet groups. Further, CPS exposure decreased hepatic carboxylesterase activity and hepatic hydrolysis of a major endocannabinoid, anandamide, in a diet-dependent manner with high-fat diet fed animals being more sensitive to CPS-mediated inhibition. These in vivo studies were corroborated by in vitro studies using rat primary hepatocytes, which demonstrated that fatty acid amide hydrolase and CES activities were more sensitive to CPS mediated inhibition than 2-arachidonoylglycerol hydrolase activity. These data demonstrate hepatic CES and FAAH activities in high-fat diet fed mice were more potently inhibited than those in normal diet fed mice following CPS exposure, which suggests that the obese phenotype may exacerbate some of the non-cholinergic effects of CPS exposure.
