Medjahed, Aboubakr published the artcileFabrication Process, Tensile, and Gamma Rays Shielding Properties of Newly Developed Fiber Metal Laminates Based on an Al-Li Alloy and Carbon Fibers-Tungsten Carbide Nanoparticles Reinforced Phthalonitrile Resin Composite, Recommanded Product: Phthalonitrile, the main research area is tungsten carbide nanoparticle phthalonitrile resin composite AlLi alloy.

In the present study, new fiber-metal laminates (FMLs) are manufactured from the lay-up process of the carbon fibers-tungsten carbide nanoparticles/phthalonitrile (CFs-WC/PN) composite and the Al-Li alloy. The properties of the developed hybrids are analyzed and compared with those of the monolithic alloy. Generally speaking, the results indicate that the amount of the fiber considerably affects the tensile properties. The mech. properties of the FMLs show enhancements over both the Al-Li alloy and the CFs/PN composite individually. When the number of the composite layers varies from 4 to 12, the ultimate tensile strength of the prepared FMLs increase from 335.3 to 690.5 MPa. The FMLs present a ductile behavior (up to a failure strain of 20%), which can be attributed to the ductile fracture morphol. of the Al-Li alloy. These improvements are the result of the synergistic combination of the high strength of composites and the superior ductility of metals. In the meantime, the gamma rays (γ-rays) shielding test reveals that increasing the weight amount of the tungsten carbide (WC) nanoparticles in the composite noticeably improves the screening ratio, reaching the exceptional value of 46% for the hybrid containing 20 wt% of WC.

Grytsai, Oleksandr published the artcileArylbiamidines: synthesis and structural studies en route to anticancer applications, Product Details of C6H4N2, the main research area is thiazolyl bromophenyl biamidine synthesis anticancer.

Biamidines are a unique and poorly studied class of nitrogenous compounds prone to tautomerization and H-bonding. Four series of heteroaryl diarylbiamidines were synthesized and the antimelanoma activity and physicochem. properties of the resulting 37 new compounds were evaluated. The dimethylthiazolyl 3-bromophenyl biamidine derivative B6 (I) inhibits the growth of six different melanoma cell lines, having higher activity than the pos. control drug, the B-RAF inhibitor PLX4032. This study introduces diarylbiamidines as promising frameworks for drug discovery.

Odani, Riko published the artcileCopper-Mediated C6-Selective Dehydrogenative Heteroarylation of 2-Pyridones with 1,3-Azoles, Safety of 4-(5-Oxazolyl)benzonitrile, the main research area is heteroarylpyridine preparation; pyridone azole heteroarylation copper; CH cleavage; arylation; copper; pyridones; synthetic methods.

A copper-mediated C6-selective dehydrogenative heteroarylation of 2-pyridones with 1,3-azoles has been developed. The reaction proceeded smoothly by two fold C-H cleavage even in the absence of noble-metal catalysts. The observed site selectivity was directed by a pyridyl substituent on the nitrogen atom of the pyridone ring. This directing group was readily removed after the coupling event, thus leading to 2-pyridone derivatives with a free N-H group. Moreover, in some cases, catalytic turnover of the Cu salt was also possible with the ideal terminal oxidant: mol. oxygen in air.

The authors report a simple synthesis protocol for making phthalocyanines (Pcs) starting from phthalonitriles. This method is general and requires no specialized equipment. The complexes are isolated and characterized using x-ray diffraction, NMR, FTIR and Raman spectroscopy and high-resolution mass spectrometry. First, the authors study and present a 1-step synthesis route to a metal-free Pc (H2PcH16), as well as to the corresponding MPcH16 complexes of Mn, Fe, Co, Ni, Cu and Zn. Then, this route can also be used to make the fluorinated Pc analogs (MPcF16). Finally, the authors present a new and useful procedure for inserting a metal ion into a metal-free H2PcH16 ring, by direct metalation, yielding the corresponding MPcH16 complex. This last method is especially useful if you want to make different MPcH16 complexes.

Carbonization of carbon fabric reinforced plastics (CFRPs) with phthalonitrile matrixes at 1000°C was investigated. Four different carbonization modes were tested. It was explored, that a mode with step heat rate is most beneficial. Two different phthalonitrile resins were investigated. Elemental anal. of final carbon-carbon composite (C/C) matrix was carried out and the results showed up to 88.5 mass% carbon presence. Final C/C d. reached 1.5991 after only one cycle of impregnation-carbonization. Final porosity of samples reached 9.2%.

Xiao, Xiao published the artcileHHQ-4, a quinoline derivate, preferentially inhibits proliferation of glucose-deprived breast cancer cells as a GRP78 down-regulator, Related Products of nitriles-buliding-blocks, the main research area is breast cancer cell proliferation HHQ4 anticancer agent GRP78; Breast cancer cells; Glucose deprivation; Glucose-regulated protein 78; HHQ-4; Unfolded protein response.

As a central regulator for endoplasmic reticulum (ER) stress, glucose-regulated protein 78 (GRP78), controls the activation of ER-transmembrane signaling mechanisms by inducing unfolded protein response (UPR) in response to ER stress. Based on this premise, we investigated the mol. mechanisms of a synthetic quinolone derivative, 2-hexyl-3-methyl-4(1H)-quinolinone (HHQ-4), in regulating the GRP78 expression and UPR transcriptional program under glucose deprivation or 2-deoxy-D-glucose (2-DG)-stressed conditions. We found that HHQ-4 suppressed the transcriptional and translational expression of GRP78 gene in glucose-deprived breast cancer cells. Constitutive expression of GRP78 completely prevented breast cancer cells from HHQ-4-mediated proliferation inhibition during glucose starvation, stressing the important role of suppression of the GRP78 in HHQ-4-mediated cell proliferation inhibition. HHQ-4 was also found to exert inhibitory activity against breast cancer cell proliferation by suppressing three survival arms of the UPR, including PERK/eIF2a/ATF4, IRE1/XBP1, and ATF6, which orchestrate an intricate signaling network to modulate GRP78 gene transcription under glucose-deprived stress. Our findings show HHQ-4 could be a promising candidate, alone or in combination with 2-DG, for selectively inhibiting breast cancer cell proliferation by down-regulating the transcription and expression of GRP78 under stressful microenvironments.

Kurosawa, Miki B. published the artcileUnified synthesis of multiply arylated alkanes by catalytic deoxygenative transformation of diarylketones, HPLC of Formula: 42872-30-0, the main research area is diarylketone palladium catalyst reduction; diarylmethane preparation; oxomethyldiarene palladium catalyst reduction dimerization; tetraarylethane preparation; triarylmethane preparation.

A deoxygenative transformation of diarylketones leading to multiply arylated alkanes was developed. Diarylketones were reacted with diphenylphosphine oxide resulting in a phospha-Brook rearrangement, followed by palladium-catalyzed cross-couplings or a Friedel-Crafts type alkylation to afford the corresponding multiply arylated alkanes. A variety of diarylketones was converted to multiply arylated alkanes such as diarylmethanes, tetraarylethanes and triarylmethanes by reduction, dimerization and arylation in one pot. Furthermore, a one-pot conversion from arylcarboxylic acids to diarylmethanes and tetraarylethanes and a synthesis of tetraarylmethane and triphenylethane using sequential coupling reactions were also presented.
