Discovery of Isonicotinamides as Highly Selective, Brain Penetrable, and Orally Active Glycogen Synthase Kinase-3 Inhibitors

GSK-3 is a serine/threonine kinase that has numerous substrates. Many of these proteins are involved in the regulation of diverse cellular functions, including metabolism, differentiation, proliferation, and apoptosis. Inhibition of GSK-3 may be useful in treating a number of diseases including Alzheimer’s disease (AD), type II diabetes, mood disorders, and some cancers, but the approach poses significant challenges. Here, we present a class of isonicotinamides that are potent, highly kinase-selective GSK-3 inhibitors, the members of which demonstrated oral activity in a triple-transgenic mouse model of AD. The remarkably high kinase selectivity and straightforward synthesis of these compounds bode well for their further exploration as tool compounds and therapeutics.

Reactions of gold(I) acetylides with l,1′-diisocyanoferrocene: From orthodox to unorthodox behavior

1,1′-Diisocyanoferrocene (1) reacts with the gold(I) acetylides [Au(C?C-p-C6H4R)]n (2a R = CF3, 2b R = H, 2c R = OMe, 2d R = NMe2) to afford the respective dinuclear gold complexes [{Au(C?C-p- C6H4R)}2(mu-1)] (3), whose aurophilic aggregation in the solid state depends on the nature of the substituent R. The product of the reaction of 1 with [Au(C?C-Fc)] n (2e, Fc = ferrocenyl) is the hexanuclear gold cluster [(Fc-C?C-Au-C?N-C5H4)Fe{C5H 4-N=C(Au)-C?C-Fc}]3, which is composed of three subunits 4 and exhibits an unusual arrangement of gold atoms. The formation of (4)3 is based on a different specific reaction of the two chemically equivalent functional groups of 1 with 2e, viz., coordination and 1,1-insertion. This “schizoid” behavior apparently is a novel variant of induced reaction asymmetry and constitutes a new phenomenon in chemistry. The reaction of 2e with l,1′-bis(diphenylphosphanyl)ferrocene (5) affords the expected [(Au-C?C-Fc)2(mu-5)] (6), which does not exhibit aurophilic interactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1,1-Bis(diphenylphosphino)ferrocene, you can also check out more blogs about12150-46-8

Recent advances in copper complexes for electrical/light energy conversion

A great deal of research effort has been put in green energy applications in the past few decades based on organic optoelectronics. Compared with conventional inorganic semiconductors, organic counterparts offer a much simpler strategy for low-cost mass production and structural modification. Hence, continuous and intensive academic and industrial research works have been done in these areas. In terms of the materials used, transition-metal complexes with the unique features of the transition metal centers represent a large group of candidates, showing high performance in energy conversion technologies. However, the commonly used transition metals, like Pt(II), Ir(III) and Ru(II), are expensive and of relatively low abundance. Concerning elemental sustainability and marketability, some abundant and cheaper metals should be investigated and further developed to replace these precious metals. Cu(I) complexes have shown their potentiality in solar energy harvesting and light emitting applications, due to their well-studied photophysics and structural diversity. In addition, copper is one of the earth-abundant metals with less toxicity, which makes it competitive to precious transition metals. As a result, a series of rational molecular engineering has been developed to boost the device performance of copper complexes. In this review, the recent progress of copper complexes in the fields of organic light emitting devices (OLEDs), photovoltaic cells (dye-sensitized solar cells (DSSCs) and bulk heterojunction solar cells (BHJSCs)) in the past two decades will be presented. Representative examples are chosen for discussion.

Luminescence Thermochromism of Gold(I) Phosphane?Iodide Complexes: A Rule or an Exception?

A series of gold(I) iodide complexes 1?11 have been prepared from di-, tri-, and tetraphosphane ligands. Crystallographic studies reveal that the di- (1?7) and tetrametallic (11) compounds feature linearly coordinated gold(I) ions with short aurophilic contacts. Their luminescence behavior is determined by the combined influence of the phosphane properties, metal?metal interaction, and intermolecular lattice-defined interactions. The proposed variable contribution of 3(X+M)-centered (X=halogen; M=metal) and 3XLCT (halogen to ligand charge transfer) electronic transitions into the lowest lying excited state, which is influenced by supramolecular packing, is presumably responsible for the alteration of room-temperature emission color from green (lambda=545 nm, for 11) to near-IR (lambda=698 nm, for 2). Dinuclear compounds 6 and 7 exhibit distinct luminescence thermochromism with a blueshift up to 5750 cm?1 upon cooling. Such dramatic change of emission energy is assigned to the presence of two coupled triplet excited states of 3pipi* and 3(X+M)C/3XLCT nature, the presence of which depends on both molecular structure and the crystal lattice arrangement.

Advances in metal-assisted non-electrophilic fluoroalkylation reactions of organic compounds

Metal-assisted trifluoromethylation and perfluoroalkylation reactions are probably one of the first approaches employed to achieve fluoroalkyl-group substitutions of organic substrates through the use of metals such as copper. Fluoroalkylation reactions of both aromatic and aliphatic substrates involving the employment of perfluoroalkyl halides RfX in conjunction with metallic species, and nucleophilic fluoroalkylating reagents in the presence of metals or organometallic species will be studied. Fluoroalkylation reactions utilizing electrophilic fluoroalkylating reagents in the presence of transition metals or trifluoromethylthiolation reactions will not be the subject of this article. Recently emerging literature (2011-present), with special emphasis on updates from previous review articles on the metal-mediated fluoroalkylation of aromatic substrates will be dealt with.

Photoluminescent tetrazolate-based Eu(III) complexes: An outstanding impact of aromatic phosphine oxide co-ligands on the photoluminescence quantum yields

New ternary Eu(III) 5-(2-pyridyl-1-oxide)tetrazolate complexes with phosphine oxide co-ligands have been synthesized and characterized by elemental analysis, and IR and 1H NMR spectroscopic techniques. The analytical data revealed that these complexes are mononuclear, and the central Eu(III) ion is coordinated by three oxygen and three nitrogen atoms of the tetrazolate and two oxygen atoms from the phosphine oxide ligands. The ancillary ligands increased remarkably the luminescence efficiency of the Eu(III) tetrazolate.

Recent advances in organic light-emitting devices comprising copper complexes: A realistic approach for low-cost and highly emissive devices?

The past decades have driven a great deal of interest for developing low-cost electroluminescent devices. In this aim, highly emissive phosphors based on Earth-abundant metals and presenting the advantage of environment-benignancy are actively researched. Based on these requirements, copper(I) complexes have been identified as favorable candidates that could advantageously replace the well-established iridium(III) complexes.
