The dual-target inhibitors tend to improve the response rate in treating tumors, comparing with single-target inhibitors. Matrix metalloproteinase-2 (MMP-2) and histone deacetylase-6 (HDAC-6) are attractive targets for cancer therapy. In this study, hierarchical virtual screening of dual MMP-2/HDAC-6 from natural products is investigated. pharmacophore model MMP-2 built based on ligands, but HDAC-6 experimental crystal structures multiple receptor-ligand complexes. reliability these two...

Aiming at the separation of Pd(II) along with MA(III) from high-level liquid waste, a porous silica based adsorbent isoBu-BTP/SiO2-P was prepared. The adsorption properties toward were investigated. It found that increase HNO3 concentration, ability increased initially as concentration until 1 M, then remained unchanged further increased. kinetics and isotherm onto fit well pseudo-second-order rate law Langmuir model, respectively. thermodynamic parameters revealed process spontaneous...

Directly separating minor actinides (MA: Am, Cm, etc.) from high level liquid waste (HLLW) containing lanthanides and other fission products is of great significance for the whole nuclear fuel cycle, especially in aspects reducing long-term radioactivity simplifying post-processing separation process. Herein, a novel silica-based adsorbent Me2-CA-BTP/SiO2-P was prepared by impregnating Me2-CA-BTP (2,6-bis(5,6,7,8-tetrahydro-5,8,9,9-tetramethyl-5,8-methano-1,2,4-benzotriazin-3-yl)pyridine)...

The adsorption properties of a porous silica-based adsorbent 2,6-bis(5,6,7,8-tetrahydro-5,8,9,9-tetramethyl-5,8-methano-1,2,4-benzotriazin-3-yl)pyridine (Me2-CA-BTP/SiO2-P) towards Pd(II) were investigated. ability Me2-CA-BTP/SiO2-P increased dramatically with the increase HNO3 concentration and showed saturated uptake after reached 3 mol/dm3. It was found that nitrate ion would participate in reaction. Palladium kinetic isotherm accordance pseudo-second-order rate law Langmuir model,...

2,6-Bis(5,6-diisohexyl-1,2,4-triazin-3-yl)pyridine (isoHexyl-BTP) is a nitrogen-donor chelating ligand which shows high extraction selectivity for minor actinides (MA) over lanthanides (Ln). We synthesized macroporous sillica/polymer-based isoHexyl-BTP adsorbent (isoHexyl-BTP/SiO2-P) the separation of MA(III) from Ln(III) in high-level liquid waste. The work focused on isoHexyl-BTP/SiO2-P adsorption mechanism towards nitric acid solution and coordination chemistry between through batch...

We report the synthesis, single-crystal structure, solid-state ultraviolet–visible–near-infrared spectroscopy, and theoretical calculations on first trivalent plutonium crown ether inclusion complex, [(H3O)(18-crown-6)][Pu(H2O)4(18-crown-6)](ClO4)4·2(H2O) (denoted as PuIII-18C6). Single-crystal X-ray diffraction reveals that PuIII-18C6 crystallizes in orthorhombic space group of Pccn, which is assembled by independent ionic pairs including [Pu(H2O)4(18-crown-6)]3+, [(H3O)(18-crown-6)]+,...

Aiming at the selective recovery of fission palladium(II) from high-level liquid waste (HLLW), silica/polymer (SiO2-P)-based isoHex-BTP adsorbent (isoHex-BTP/SiO2-P) was synthesized by impregnating complexing agent into multiporous SiO2-P inert support. The feasibility separation Pd(II) HLLW isoHex-BTP/SiO2-P evaluated batch experiment method. results showed that exhibited much higher adsorption selectivity for than other products, even Am(III) and Pu(IV) presented in HLLW. ideal nitric acid...

Matrix metalloproteinase-9 (MMP-9) has been considered as an attractive target involving cancer therapy. In this study, the 3D QSAR pharmacophore model of MMP-9 inhibitors is built, and its reliability subsequently validated based on different methods. The built consists four chemical features, including two hydrogen bond acceptors (HBA), one hydrophobic (HY), ring aromatic (RA). Among them, both HY RA are found to be especially important features because they involve interactions with S1′...

Genetic variation and population structure of northern snakehead (Channa argus) from eight locations in China were investigated using mitochondrial DNA control region adjacent regions sequences. Sequence analysis showed that there 105 haplotypes 260 individuals, 48 unique 57 shared haplotypes, but no common haplotype by all populations. As a whole, the diversity was high (h = 0.989), while nucleotide low (π 0.00482). AMOVA detected significant genetic differentiation among populations (FST...

This 8 week feeding trial evaluated the effects of three stimulants (FS) on feed intake, growth performance, body composition, serum biochemical parameters, and digestive enzyme activities for juvenile GIFT tilapia fed low fishmeal diets. Four test diets were supplemented with 0, 16 g/kg taurine (Tau), 0.4 mixed nucleotides (Mix-NT), 30 squid liver paste (SQLP) respectively, to strain Oreochromis niloticus (3.34±0.01 g).
