In a document, author is Barr, John T., introduce the new discover, Application of 7507-86-0.

The goal of this study was to provide a reasonable assessment of how probe substrate selection may impact the results of in vitro aldehyde oxidase (AO) inhibition experiments. Here, we used a previously studied set of seven known AO inhibitors to probe the inhibition profile of a pharmacologically relevant substrate N-[(2-dimethylamino)ethyl]acridine-4-carboxamide (DACA). DACA oxidation in human liver cytosol was characterized with a measured V-max of 2.3 +/- 0.08 nmol product . min(-1) . mg(-1) and a K-m of 6.3 +/- 6 0.8 mu M. The K-ii and K-is values describing the inhibition of DACA oxidation by the panel of seven inhibitors were tabulated and compared with previous findings with phthalazine as the substrate. In every case, the inhibition profile shifted to a much less uncompetitive mode of inhibition for DACA relative to phthalazine. With the exception of one inhibitor, raloxifene, this change in inhibition profile seems to be a result of a decrease in the uncompetitive mode of inhibition (an affected K-ii value), whereas the competitive mode (K-is) seems to be relatively consistent between substrates. Raloxifene was found to inhibit competitively when using DACA as a probe, and a previous report showed that raloxifene inhibited uncompetitively with other substrates. The relevance of these data to the mechanistic understanding of aldehyde oxidase inhibition and potential implications on drug-drug interactions is discussed. Overall, it appears that the choice in substrate may be critical when conducting mechanistic inhibition or in vitro drug-drug interactions prediction studies with AO

A tridentate Schiff base ligand, (E)-3-((2-hydroxy-3-methoxybenzylidene)amino)-2-methylquinazolin-4(3H)-one [HL], and its mixed-ligand Ni(II) complex [Ni(L)(imi)], were synthesized and fully characterized using elemental analysis, FT-IR, UV-Vis and (HNMR)-H-1 spectroscopy techniques. The structure of the synthesized ligand and complex was determined with single crystal X-ray diffraction method. In the complex, a square planner geometry was observed around the Ni(II) central atom coordinated with the donor atoms of the Schiff base ligand and one nitrogen of imidazole group. In addition, the catalytic activity of the complex on the three-component condensation of hydrazine hydrate with phthalic anhydride and dimedone to obtain 2H-indazolo[2,1-b]phthalazine-triones was investigated.

In a document, author is Xu, Xianlin, introduce the new discover.

High temperature-resistant separation membranes are widely considered in various fields. However, incompetent support layer limits the performance of high temperature-resistant membranes severely. In this work, a homogeneous composite nonwoven support (HCNS) is developed by wet-laid and hot-pressing technology using undrawn polyethylene terephthalate fibers as bonding fibers. The significance of hot-pressing parameters on the performances of the HCNS is investigated, and quadratic regression models are established. The HCNS exhibits a smooth surface (roughness of 118 nm) and a porous structure (porosity of 21.06% and pore size of 6.548 mu m) with a mechanical property (tensile index of 45.80 N m g(-1)). The ultrafiltration membranes supported by the HCNS are prepared from poly(phthalazine ether sulfone ketone), which demonstrates high permeance, high rejection rate, and long-term stability at raised operation temperature, thereby suggesting the potential application of HCNS in high-temperature filtration.
