Li, Lin published the artcileA Small-Molecule Probe for Selective Profiling and Imaging of Monoamine Oxidase B Activities in Models of Parkinson’s Disease, Product Details of C7H13BrSi, the publication is Angewandte Chemie, International Edition (2015), 54(37), 10821-10825, database is CAplus and MEDLINE.

The design of the first dual-purpose activity-based probe of monoamine oxidase B (MAO-B) is reported. This probe is highly selective towards MAO-B, even at high MAO-A expression levels, and could sensitively report endogenous MAO-B activities by both in situ proteome profiling and live-cell bioimaging. With a built-in imaging module as part of the probe design, the probe was able to accomplish what all previously reported MAO-B imaging probes failed to do thus far: the live-cell imaging of MAO-B activities without encountering diffusion problems.

Zeng, Xiao-Lan published the artcileQSPR study on octanol/water partition coefficient (lgK_ow) of substituted naphthalin compounds, Recommanded Product: 1,3-Dibromonaphthalene, the publication is Chinese Journal of Structural Chemistry (2007), 26(3), 281-286, database is CAplus.

Structural parameters of 24 substituted naphthalin compounds were computed at four levels using Hartree-Fock and DFT methods. Based on the exptl. data of octanol/water partition coefficient (lgK_ow), three-parameter (energy of the HOMO (E_HOMO), the most pos. at. net charges of mol. (q⁺) and mol. average polarizability (α)) dependent equations were developed using structural parameters as theor. descriptors. Especially, lgK_ow dependent equation calculated at the HF/6-311G** level is more advantageous than others in view of their correlation and predictive abilities. This dependent equation was validated by variance inflation factors (VIF) and t-test methods and used to predict lgK_ow of eight designed compounds Upon comparison, the predictive abilities of our work are all more advantageous than those calculated from mol. property calculator program.

One-step synthesis and micropatterning of different types of carbon nanomaterials, such as amorphous carbon or three-dimensional graphene which have versatile electrochem., thermal, and mech. properties, are advantageous for the fabrication of microelectronics, sensors, and wearable devices. Here, we report a direct laser writing method to simultaneously synthesize and pattern graphitic carbon from liquid organic precursors. We have tested a wide range of liquid organic precursors and identified the chem. characteristics that are beneficial for successful laser-induced solvothermal deposition. The laser-deposited carbon exhibits a paracryst.-to-polycrystalline structure and has elec. resistivities on the order of 10^-3 to 10^-4 Ω m which is tunable through variations in the laser power. Such properties of the laser-deposited carbon, coupled with the ability to direct-write custom patterns with microscale resolution, make these carbon materials exciting candidates for use in applications such as energy storage and sensing.

Tzerpos, Nikolaos I. published the artcileDiphenylpyridylmethyl radicals. Part 1. Synthesis, dimerization and ENDOR spectroscopy of diphenyl(2-, 3- or 4-pyridyl)methyl radicals; bond dissociation enthalpies of their dimers, Formula: C6H12Br2, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1995), 755-61, database is CAplus.

Ortho-ortho hydrogen van der Waals repulsions are the origin of the propeller shape of the triphenylmethyl radical and the main reason for the low bond dissociation enthalpy (BDH) of its dimer I (44.8 J mol^-1). In order to reduce these steric repulsions (eliminating some aromatic hydrogens), diphenyl(2-, 3- or 4-pyridyl)methyl radicals (e.g, II) were prepared through reductive dehalogenation of the corresponding triarylchloromethanes (e.g., III) with silver in benzene. They form α,p-dimers IV–VI exclusively through the pyridine ring. ENDOR spectroscopy shows that the structure of the radicals, does not deviate substantially from that of the parent radical, Ph₃C•. In contrast, the BDH values of the dimers (measured using ESR spectroscopy) show strengthening of the central C-C bond in IV (88.7 kJ mol^-1) and V (90.0 kJ mol^-1) and a similar value for VI (46.4 kJ mol^-1) with respect to the trityl dimer I. This is a consequence of the ground state stabilization of the dimers IV–VI due to relief of strain (elimination of ring hydrogens), whereas in the case of VI, this stabilization is probably compensated by the formation of a weaker C-N bond with respect to the C-C bond. The above dimers undergo easy 1,5-H-rearrangement, autocatalyzed by the basic pyridyl groups themselves.

Huang, Qi published the artcileInexpensive Radical Methylation and Related Alkylations of Heteroarenes, SDS of cas: 401-55-8, the publication is Organic Letters (2018), 20(5), 1413-1416, database is CAplus and MEDLINE.

A simple method for the introduction of a Me and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-Me pyrrolidone in a microwave oven.

B(C₆F₅)₃ was found to catalyze an unusual double reduction of oxetanes by hydrosilane with aryl migration via neighboring group participation. Control experiments suggested that the phenonium ion serves as the key intermediate. Minor modification of this protocol also led to simple hydrosilylative opening of oxetanes.

Caldirola, P. published the artcileNew prenylamine-analogs: investigations of their influence on calcium-dependent biological systems, Quality Control of 1997-80-4, the publication is European Journal of Medicinal Chemistry (1993), 28(7-8), 555-68, database is CAplus.

Chem., prenylamine belongs to the diphenylalkylamine class. Compounds of this class are calcium antagonists with a broad spectrum of activities due to their influence on both extracellular and intracellular sites. In the present study the calcium antagonistic profile of a recently developed new series of prenylamine analogs has been investigated using different in vitro systems. The inhibiting concentrations for the most active compound are ≈ 1.5 μM; several derivatives are inactive up to a concentration of 10 μM. Structural modifications towards an increase of lipophilicity make these mols. interact (inhibition) with the intracellular calcium-binding protein calmodulin; for the series no correlation between calcium-blocking and calmodulin antagonistic effects has been found.
