Neg. modulators of metabotropic glutamate 2 & 3 receptors demonstrate antidepressant-like activity in animal models and hold promise as novel therapeutic agents for the treatment of major depressive disorder. Herein we describe our efforts to prepare and optimize a series of conformationally constrained 3,4-disubstituted bicyclo[3.1.0]hexane glutamic acid analogs as orthosteric (glutamate site) mGlu2/3 receptor antagonists. This work led to the discovery of a highly potent and efficacious tool compound I (hmGlu2 IC50 46 ± 14.2 nM, hmGlu3 IC50 = 46.1 ± 36.2 nM). Compound I showed activity in the mouse forced swim test with a minimal ED (MED) of 1 mg/kg i.p. While in rat EEG studies it exhibited wake promoting effects at 3 and 10 mg/kg i.p. without any significant effects on locomotor activity. Compound I thus represents a novel tool mol. for studying the impact of blocking mGlu2/3 receptors both in vitro and in vivo.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Hazardous Materials called Porous zeolite imidazole framework-wrapped urchin-like Au-Ag nanocrystals for SERS detection of trace hexachlorocyclohexane pesticides via efficient enrichment, Author is Zhou, Xia; Liu, Guangqiang; Zhang, Hongwen; Li, Yue; Cai, Weiping, which mentions a compound: 16961-25-4, SMILESS is Cl[Au-](Cl)(Cl)Cl.[H]O[H].[H]O[H].[H]O[H].[H+], Molecular AuCl4H7O3, HPLC of Formula: 16961-25-4.

A core-shell configuration of the zeolite imidazole framework (ZIF-8) wrapped urchin-like Au-Ag alloyed nanocrystals (UAANs) were designed and fabricated via adding the pre-formed plasmonic nanoparticles into the ZIF-8 precursor solution with hexadecyltrimethyl ammonium bromide (CTAB). The UAANs are about 100 nm in size with high-d. tips. The ZIF-8 shell layer is nanoporous and can be controlled in thickness from 10 nm to 40 nm by the CTAB concentration Importantly, such ZIF-8 wrapped UAANs can be used as the highly efficient surface enhanced Raman scattering (SERS) substrates for detection of the trace hexachlorocyclohexane (HCH) mols. The ZIF-8 shell layer with an appropriate thickness (-∼20 nm) can evidently increase the SERS performance of the UAANs to the trace γ-HCH and α-HCH. Such wrapping-enhanced SERS effect significantly increases, by a power function, with the decreasing HCH concentration, especially in the concentration below 10-6 M, which is attributed to the ever-increasing enrichment effect to the HCH mols. The detection limit is down below 1.5 ppb. This work presents a highly efficient substrate for the SERS-based detection of the trace HCH, and also displays the potential application in the SERS detection of volatile small mols.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3-Pyridinepropionic acid, is researched, Molecular C8H9NO2, CAS is 3724-19-4, about Amyloidogenic immunoglobulin light chain kinetic stabilizers comprising a simple urea linker module reveal a novel binding sub-site.Application of 3724-19-4.

In Ig light chain (LC) amyloidosis, the misfolding, or misfolding and misassembly of LC a protein or fragments thereof resulting from aberrant endoproteolysis, causes organ damage to patients. A small mol. “”kinetic stabilizer”” drug could slow or stop these processes and improve prognosis. We previously identified coumarin-based kinetic stabilizers of LCs that can be divided into four components, including a “”linker module”” and “”distal substructure””. Our prior studies focused on characterizing carbamate, hydantoin, and spirocyclic urea linker modules, which bind in a solvent-exposed site at the VL-VL domain interface of the LC dimer. Here, we report structure-activity relationship data on 7-diethylamino coumarin-based kinetic stabilizers. This substructure occupies the previously characterized “”anchor cavity”” and the “”aromatic slit””. The potencies of amide and urea linker modules terminating in a variety of distal substructures attached at the 3-position of this coumarin ring were assessed. Surprisingly, crystallog. data on a 7-diethylamino coumarin-based kinetic stabilizer reveals that the urea linker module and distal substructure attached at the 3-position bind a solvent-exposed region of the full-length LC dimer distinct from previously characterized sites. Our results further elaborate the small-mol. binding surface of LCs that could be occupied by potent and selective LC kinetic stabilizers.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 87488-84-4, is researched, Molecular C9H7BrN2, about Cyclometalated complexes of platinum(II): homoleptic compounds with aromatic C,N ligands, the main research direction is cyclometalated platinum NMR UV voltammetry; lithiopyrazole cyclocondensation platinum chloride; lithiopyridine cyclocondensation platinum chloride; reduction electrochem cyclometalated platinum.Recommanded Product: 1-(2-Bromophenyl)-1H-pyrazole.

The synthesis of five new homoleptic bis(cyclometalated) Pt(II) complexes, e.g., cis-bis(2-phenylpyridinato)platinum (I), cis-bis[2-(2-thienyl)pyridinato]platinum (II), and cis-bis[1-(2-thienyl)pyrazolato]platinum (III), from trans-PtCl2(SEt2)2 and the lithiated ligands at low temperature is described. All compounds are air-stable, soluble in many organic solvents, and photoreactive in solution under irradiation with visible light. The strong low-energy bands in the electronic spectra in the range from 400 to 450 nm are assigned to metal to ligand charge-transfer (MLCT) transitions from a Pt(5d) orbital to an empty π* orbital of the ligands. Most spectra show a weak absorption superimposed on the low-energy side of the strong MLCT band. This weak absorption is attributed to a singlet-triplet transition of the same type as the strong band. The complexes can be reduced electrochem. in reversible one-electron steps. Oxidation occurs also, but in a completely irreversible manner.
