Advisor on first aid management of chemical splashes. Advisor on management on chemical spills and leaks in the industry.Training of industrial personnel on site about first aid measures of decontamination of chemical splashes.

Abstract

PREVOR is a toxicology laboratory specialised in the emergency management of chemical splashes. Chemicals and their associated risks are a real concern. History has shown that the traditional use of water as a mean of emergency decontamination,whilst beneficial, has its limits. These limits may result in a chemical burn. Scientific advancement and deep understanding of the chemical injuries mechanism have allowed new rinsing solutions to be developed which permit to prevent or reduce the seriousness of chemical injuries. The specificity of hydrofluoric acid burns and its first aid management will also be detailed through industrial case reports and scientific experiments. Finally practical information will be shared, on the use of these medical devices at the workplace.

Abstract

Environmentally benign, operationally simple, and robust reactions, particularly those employing reusable solid catalysts and water as a solvent, are of significant interest to the chemical industry. Here, heterogeneous palladium catalysts supported on ordered mesoporous carbonaceous nanocomposites including carbon-silica, CoO-C and quaternary ammonium phase transfer agent modified mesoporous carbonaceous resins, were applied to the water-mediated C-C bonds formation. The mesoporous Pd/CoO-C catalyst showed a high yield of biphenyl (49%) in the water-mediated Suzuki coupling reaction of chlorobenzene and phenylboronic acid. Product yields in the reaction of aryl chlorides containing electron-withdrawing groups attached to their benzene ring can reach approximately 90%. Very small Pd clusters consisting of approximately 3 atoms and Pd-O bonds formed on the interface between CoO and Pd nanoparticles.The unsaturated coordinative Pd may be responsible for theactivation of chlorobenzene in the absence of any additives or ligands. A nitrogen-containing functional group modified and ordered mesoporous resin material was also used to support a reusable solid Pd catalyst. The grafted quaternary N coordination with highly dispersed Pd NPs creates an electronically rich environment for surface atoms and causes a distinct enhancement in the stabilization and accessibility of these particles to organic substances in aqueous solution. The mesoporous Pd catalysts are active in the C-2 arylation of N-methylindole when water is used as the solvent without any other additive or the exclusion of air. The catalysis likely occurs on the Pd surface rather than in solution. thiol-functionalized mesoporous silica, which can trap soluble Pd species, was used to confirm the negligible leaching in solution and therefore heterogeneous reaction. These heterogeneous catalyst are stable, showing unobvious activity loss after ten catalytic runs. Additionally, uniform mesopores and the hydrophobic nature of the carbon support may also facilitate the mass transfer of the reactant molecules and enrichment inside pores.

Abstract

The convergence of supramolecular chemistry and polymer science especially porphyrin chemistry offers many powerful approaches for building functional nanostructures with welldefined dynamic behavior. The efficient metal-free three-component reactions to synthesize 1,4,5-trisubstituted 1,2,3-porphyrin triazoles from available materials, such as porphyrin-aldehydes, nitroalkanes, and organic azides, and also from porphyrin aldehydes, nitroalkanes, and porphyrin azides is described. The process is enabled by an organocatalyzed (morpholine:p-toluenesulfonicacid) Knoevenagel condensation of the formyl group with the nitro compound, which is followed by the 1,3-dipolar cycloaddition of the azide to the activated alkene. The reaction features an excellent substrate scope, and the products are obtained with good yield and regioselectivity. This methodology was used for the synthesis of fused triazole heterocycles from nitroporphyrin and organic azides.

Abstract

Oxidative cross-dehydrogenative coupling methodology lies in the modern trend of organic chemistry. It eliminates necessity for installation of additional functional groups and affords direct coupling in one stage (via selective C-H activation) with limited amount of wastes, high atom- and step- economy. Oxidative cross dehydrogenative C-C coupling were studied in detail; the C-N, C-P, and C-O cross coupling reactions are less well developed. It is difficult to achieve high selectivity in the cross-dehydrogenative C-O coupling because the starting compounds are prone to side oxidation and fragmentation reactions giving, for example, alcohols and carbonyl compounds. This gives rise to a problem of searching for oxidizing agents and reaction conditions suitable for the cross-coupling of different types of substrates. We discovered oxidative cross C-O coupling of 1,3-dicarbonyl compounds, their heteroanalogs and heterocycles with peroxides, oximes and hydroxyamides. The best result obtained with the use of the widely available copper, iron, manganese or lanthanide salts as catalysts or oxidants.

Abstract

The cytotoxic effects of chemotherapy and radiation thatnare clinically used to treat malignances aren directly related to their propensity to generate DNA damage. The capacity of cancer cells to recognize DNA damage and initiate DNA repair is a key mechanism for therapeutic resistance to chemotherapy. Therefore, the targeting of DNA repair enzymes can be used as a strategy to potentiate the cytotoxicity of the currently available DNA damaging agents towards cancer cells. PARP1 (poly ADP ribose polymerase 1, the enzyme involved in DNA repair) inhibitors such as Olaparib, Rucaparib and Niraparib are in clinical use already. New and very promising target for antitumor therapy is tyrosyl-DNA phosphodiesterase 1 (Tdp1). It plays a key role in the removal of DNA damage resulting from inhibition of topoisomerase 1 (Topo1) with camptothecin and its clinical derivatives irinotecan and topotecan. Furthermore, Tdp1 is known to be capable of removing the DNA damage induced by other anticancer drugs commonly used in clinical practice. To date, a number of Tdp1 inhibitors of various types including dual Tdp1/Topo1 inhibitors are known. A set of very potent Tdp1 inhibitors was found by us among natural products derivatives. We designed new inhibitors using targeted modifications of terpenoids, coumarins, usnic acid and other types of natural products. Moreover, we found that benzopentathiepine derivatives are very effective inhibitors of Tdp1. Important that the ability of the inhibitors used in nontoxic concentration to enhance the cytotoxicity of camptothecin and topotecan, the established topoisomerase 1 poison, was demonstrated. Thus, we discovered of new original Tdp1 inhibitors, effectively inhibiting DNA repair in tumor cells for use as the components of complex anticancer drugs.

Abstract

Ligand-based or structure-based in silico methods, as well as in vitro methods were used for the evaluation of the inhibition of Mus musculus and Homo sapiens acetylcholinesterase by commercially available selected pesticides. Crystal structures  of simazine, monocrotophos, dimethoate, and acetamiprid were used for the unconstrained conformational search with various force fields (FFs) implemented in Monte Carlo/Multiple Minimum (MC/MM) approach. Unconstrained conformational searches were applied in the determination of intersynaptic pre-bound conformations of other commonly used pesticides (atrazine, propazine, carbofuran, carbaryl, tebufenozide, imidacloprid, diuron, monuron, and linuron). Moreover, energies of global minima, calculated with the best performing FFs, were compared with selected pesticides toxicities against Mus musculus. For the majority of pesticides, low energies of global minima in pre-bound states correlate with high toxicity. The targeted pesticides are acetylcholinesterase (AChE) inhibitors, so structure-based (SB) studies, in the form of molecular docking and molecular dynamics (MD) on either Mus musculus AChE (mAChE) or Homo sapiens AChE (hAChE), were performed to predict their pharmacology. The mechanistic pathways were established, and additionally confirmed by QM DFT mechanistic studies, which can be further used in the discovery of novel pesticides with desirable lower toxicity against humans. We paid special attention to the mechanism of hAChE inhibition by atrazine, propazine, and simazine. The QM DFT (quantum mechanics – density functional theory) mechanistic studies implied that atrazine, propazine, and simazine could be considered as reversible hAChE inhibitors, administered in high concentrations, and confirmed by concentration-dependent kinetic studies of hAChE inhibition.

Biography

Aminofluorene and its derivatives have proved to be one of the most widely studied candidates among in cancer research. They have also found its applications as efficient  ds-RNA fluorescent probe. Most common approach for the synthesis of aminofluorene is based on the hydrogenation of corresponding nitro/nitrile fluorenes as starting material. However, to the best of our knowledge, decyanization reaction has never been used to obtain 1-hetarylsubstituted-3- aminofluorene. Furthermore, the desired compounds are also difficult to afford through conventional protocols such Suzuki coupling, functionalizing of bromide substituted fluorene etc. The decyanization reaction provides not only the removal of cyano groups from the structure but also unprecedented side products because of harsh reaction conditions, such as the alkylated 1-hetaryl-3-aminofluorene derivatives. In this study, on a facile protocol to obtain 1-hetaryl-3-aminofluorene and its side products besides the catalytic reduction of various corresponding nitro-substituted fluorene compounds which are difficult to synthesize by other methods. Furthermore, a proposed mechanism has been outlined for the achieved novel type of aminofluorene products by means of XRD, Mass and NMR spectroscopy.

Abstract

Using two different highly non-equilibrium synthetic approaches, we have created new kinds of stable oil-in-water nanoemulsions composed of complex multi-compartment nanoscale droplets. Each nanodroplet contains three different types of mutually immisible oils in separate internal compartments. Consequently, each internal compartment can hold a different class of oil-soluble drug molecules. By analogy to Janus droplets, which contain two different immiscible oil types and are named after the mythological two-faced deity of doorways, we call these compartmentalized triple-oil droplets “Cerberus” droplets, after three-headed watch-dog in the same mythology. In a first synthetic approach, we combine three simple microscale oil-in-water emulsions, each made using a different oil type (aliphatic, aromatic, or fluoro siloxanes), and subject this mixed microscale emulsion to extreme flow conditions using a high-pressure microfluidic homogenizer. In addition to causing droplet rupturing towards the nanoscale, the extreme flow also overcomes the stabilizing interfacial repulsion of the water-soluble ionic surfactant, leading to flow-induced droplet fusion. The multi compartment nanodroplets in these complex oil-in-water nanoemulsions are so small that optical microscopy methods cannot resolve the internal interfaces that separate the internal compartments. So, instead, we have developed the use of cryogenic transmission electron microscopy (C-TEM) to reveal the compartmentalization of these three oils inside the resulting Cerberus nanodroplets. In a second approach, we create Cerberus droplets using self-limiting droplet fusion reactions obtained by transiently destabilizing a mixed emulsion containing droplets of the three different oil types using an ionic amphiphile having the opposite charge. Based on these results, we create a classification scheme for different kinds of Cerberus droplet morphologies. In pharmaceutical applications, Cerberus nanoemulsions can be tailored to provide local co-delivery of a wide range of non-aqueous drug molecules, thereby overcoming limitations related to poor molecular solubility in certain oil types.

Abstract

Greater than 80% of drugs and biologically active natural products are  nitrogen- or oxygen-based, and many of these exist as nitrogen or oxygen heterocycles. While many such drugs and natural products are also chiral, relatively few contain chiral nitrogen/oxygen heterocycles, a limitation that is due in large part to a lack of effective and broadly applicable methods for their preparation. However, as drug development moves away from the use of unsaturated (flat), structurally simple achiral compounds and seeks out more
stereochemically sophisticated chiral compounds having higher degrees of saturation, the need for methods for the synthesis of chiral nitrogen/oxygen heterocycles has become increasingly important. We have developed stereocontrolled synthetic approaches to a wide range of saturated and partially saturated chiral nitrogen/oxygen heterocycles through the use
of two newly developed azoalkene-based moieties, the details of which are described herein.

Abstract

Advanced nanocomposites have contributed to catalysis and are prime choice for the researchers in various important catalytic protocols and benign conversions. The nanocatalysts include magnetic-nanocomposites, carbon-based nanomaterials, core-shell (Pd@Pt) catalysts and morphologydependent iron oxides. Sustainable nanotechnology improvements over the years have recommended significant and extraordinary series of progresses in the design of heterogeneous nanocatalysts. Notably, nanomaterials for catalysis can now be envisioned and organized with need for exact catalytic applications. Core shell nanocomposites, orphology-dependent iron oxide and metal supported nanoparticles can be synthesized via more ecological paths with distinctive structure, morphology and composition. Our recent research activity on the practice of nanomaterials nanocatalyst and its catalytic applications will be highlighted.
