Is intraspecies QSTR model answer to toxicity data gap filling: Ecotoxicity modeling of chemicals to avian species

Interspecies model represents an established approach for the response data gap filling for regulatory agencies and researchers. We propose a novel approach of intraspecies modeling within the animals of the same species, instead of animals from different species. The proposed intraspecies model is capable of more precise extrapolation of data than the interspecies model, as animals under the same species share a similar mechanism of action (MOA) and target sites for the response. Along with the advantage of better prediction over the interspecies model, the intraspecies model has all the significant features like recognition of MOA, species-specific toxicity, reduction of animal experimentation, and money and time. To establish and test the intraspecies modeling approach, we have modeled ecotoxicity of organic chemicals to three avian species: Anas platyrhynchos, Colinus virginianus, and Phasianus colchicus. The intraspecies models offer to identify the mechanistic interpretation of the ecotoxicity of the studied chemicals along with the toxicity data gap filling. The success of the intraspecies modeling relies on connecting the missing dots of toxicity for the regulatory purposes, especially when there is a scarcity of ecotoxicity experimental data and in silico models for avian species.

Identification of specific organic contaminants for estimating the contribution of the Elbe river to the pollution of the German Bight

GC/MS analyses have been applied to sediment samples of the German Bight in order to document the state of organic contamination as well as to identify specific molecular markers that are appropriate to estimate the discharge of anthropogenic compounds derived from the Elbe river. Detailed screening analyses revealed a wide variety of organic lipophilic compounds of biogenic, petrogenic as well as anthropogenic origin. Potential marker compounds indicating the contribution of the Elbe river could be attributed mainly to the chlorinated aromatic contaminants. Specifically, these include tetra- to hexachlorobenzenes, mono- to dichloronaphthalenes, hexachlorobutadiene, tetrabutyl tin, alkylsulfonic acid phenylesters, 1,2,3,6,7,8-hexahydro-1,1,6,6-tetramethyl-4-isopropyl-as-indacene and 4,4?dichlorodiphenylsulfide. These compounds are suitable to indicate the spatial distribution of Elbe river derived organic matter.

Meltable phenylethynyl-capped oligoimide resins derived from 1,4-bis(4-amino-2-trifluoromethylphenoxy)benzene and 3,4?-oxydianiline

A series of meltable oligoimide resins with controlled molecular weights by reactive phenylethynyl endcapping groups have been prepared by the thermal polycondensation of 3,3?,4,4?-biphenyltetracarboxylic dianhydride (s-BPDA) with the aromatic diamine mixtures consisting of different mole ratios of 1,4-bis(4-amino-2-trifluoromethylphenoxy)benzene (1,4,4-6FAPB) and 3,4?-oxydianiline (3,4?-ODA) in the presence of 4-phenylethynylphthalic anhydride (PEPA) as molecular weight-controlling and reactive endcapping reagent. Experimental results indicated that the molecular weight-controlled oligoimide resins were mixtures containing a series of biphenylethynyl-endcapped oligoimides with different chemical structures and different molecular weights. The typical oligoimide resins could be melted at temperatures of 300 C to yield stable molten fluid with melt viscosity of 13.4 Pa s, which was suitable for melt processing. The molten oligoimide resins could be further polymer chain extended and crosslinked by thermal curing of the reactive phenylethynyl groups to give strong and tough thermosetted polyimides. Thus, the oligoimide resin with calculated molecular weight of 2500 exhibited not only good meltability with low melt viscosity, but also high melt stability and fluidability at temperatures of <300 C. After thermal curing, the obtained thermosetted polyimide showed high glass transition temperature (>316 C, DMA), excellent thermal stability with initial thermal decomposition temperature of 588 C and good mechanical properties with flexural strength of 159.1 MPa, flexural moduli of 3.3 GPa, tensile strength of 94.7 MPa and elongation at breakage of 9.0%.

Influence of carboxylic acids on the reactions with chlorotetraacetatodiruthenium(II,III): X-ray crystal structure of [Ru2(mu-O2CC4H3S)4(OPPh3)2]BF4*2H2O

The reaction of Ru2Cl(mu-O2CCH3)4 with indole-2-carboxylic, N-methyl-pyrrole-2-carboxylic, furane-2-carboxylic, thiophene-2-carboxylic and benzofurane-2-carboxylic acids, which contain nitrogen, oxygen or sulphur atoms in the alpha position with respect to the carboxylate group, leads to compounds of the type Ru2Cl(mu-O2CR)4. In these compounds O,O-coordination of the carboxylate ligands has been found. The analogous reaction with quinoline-2-carboxylic acid (Hquin) gives a disproportionation process with formation of Ru(quin)3 and Ru2(quin)4; in this case, N,O-coordination of the ligand has been observed. The indole-2-carboxylato derivative has a non-polymeric structure, whereas with the other ligands polymeric structures with chlorine atoms bridging Ru2(5+) units are formed. Treatment of Ru2Cl(mu-O2CR)4 in thf or acetone with AgBF4 gave [Ru2(mu-O2CR)4L2]BF4 (L=thf, acetone; R=N-methyl-2-pyrrolyl, 2-furyl, 2-thienyl) or [Ru2(mu-O2CR)4]BF4 (R=2-benzofuryl). The axial positions of these compounds can be occupied by OPPh3 to give the corresponding [Ru2(mu-O2CR)4(OPPh3)2]BF4. The compounds have been characterized by analytical, spectroscopic and magnetic data. The structure of [Ru2(mu-O2CC4H3S)4(OPPh3)2]BF4*2H2O has been determined by X-ray crystallography. The dinuclear cation has two ruthenium atoms linked by four bridging thiophene-2-carboxylate ligands and two OPPh3 ligands coordinated to axial positions, with an Ru-Ru distance of 2.2747(11) A.

Structural analysis of PIM1 kinase complexes with ATP-competitive inhibitors

PIM1 is an oncogenic kinase overexpressed in a number of cancers where it correlates with poor prognosis. Several studies demonstrated that inhibition of PIM1 activity is an attractive strategy in fighting overexpressing cancers, while distinct structural features of ATP binding pocket make PIM1 an inviting target for the design of selective inhibitors. To facilitate development of specific PIM1 inhibitors, in this study we report three crystal structures of ATP-competitive inhibitors at the ATP binding pocket of PIM1. Two of the reported structures (CX-4945 and Ro-3306) explain the off-target effect on PIM1 of respectively casein kinase 2 and cyclin-dependent kinase 1 dedicated inhibitors. In turn, the structure with CX-6258 demonstrates a binding mode of a potent, selective inhibitor of PIM1, PIM2, PIM3 and Flt-3 kinases. The consequences of our findings for future inhibitor development are discussed.
