A Cyclometalated Ruthenium-NHC Precatalyst for the Asymmetric Hydrogenation of (Hetero)arenes and Its Activation Pathway

This study describes the structural investigation of a highly versatile ruthenium-NHC (N-heterocyclic carbene) catalyst complex, which has been established for the asymmetric hydrogenation of various aromatic compounds. A complex containing an unusual doubly deprotonated NHC ligand was isolated and identified as the precatalyst to this complex. When its subsequent reactivity was monitored, two additional precatalysts, featuring partially hydrogenated naphthyl substituents, were characterized spectroscopically. Ligand hydrogenation appears to be a key activation process en route to the active catalyst.

Structure-activity relationship of human glutaminyl cyclase inhibitors having an N-(5-methyl-1H-imidazol-1-yl)propyl thiourea template

In an effort to design inhibitors of human glutaminyl cyclase (QC), we have synthesized a library of N-aryl N-(5-methyl-1H-imidazol-1-yl)propyl thioureas and investigated the contribution of the aryl region of these compounds to their structure-activity relationships as cyclase inhibitors. Our design was guided by the proposed binding mode of the preferred substrate for the cyclase. In this series, compound 52 was identified as the most potent QC inhibitor with an IC50 value of 58 nM, which was two-fold more potent than the previously reported lead 2. Compound 52 is a most promising candidate for future evaluation to monitor its ability to reduce the formation of pGlu-Abeta and Abeta plaques in cells and transgenic animals.

What is the composition of AIR? Pyrolysis-GC-MS characterization of acid-insoluble residue from fresh litter and organic horizons under boreal forests in southern Finland

High concentrations of the acid-insoluble residue (AIR, also known as “Klason lignin”) in decomposing litter are considered to indicate high resistance to decomposition; however, the chemical composition of AIR in different types of litter and soil organic matter is poorly understood. In the present study, we characterized samples of common litter (L) types in boreal forests (needle, coarse tree, and moss), as well as fragmented litter (F), and humus (H) layers in two south boreal forest sites using a combination of sequential fractionation and pyrolysis-GC-MS. The results showed that the unfractionated samples were composed of cellulose-derived carbohydrates, guaiacyl-type lignin and other polyphenolic compounds, and that there was little variation among samples. However, pyrolysis-GC-MS analyses of AIR demonstrated that the composition of the AIR fraction differed among the analyzed litter materials as well as between the layers in the soil organic horizon. In the F and H layers, the AIR fraction contained guaiacyl-type lignin and other polyphenolics, as well as lipophilic compounds, which were indicated by the pyrolysis product methyldehydroabietate and short-chain fatty acids. In the AIR fraction, only small amounts of carbohydrate-derived compounds were detected, confirming that the sequential fractionation method efficiently removes soluble polysaccharides. The AIR fraction was poorly soluble in all solvents. The results presented here confirm that the sequential fractionation method efficiently separates water-, chloroform-, and acid-soluble (72% H2SO4) compounds from acid-insoluble compounds (AIR). However, AIR was shown to be a mixture of polyphenolic (mainly lignin-derived) and lipophilic (including fatty acids and resin acid) structures, and may therefore be a poor indicator of lignin and phenolic compounds when investigating the F and H layers in the organic horizon.

Discovery of dual inhibitors targeting both HIV-1 capsid and human cyclophilin A to inhibit the assembly and uncoating of the viral capsid

HIV-1 assembly and disassembly (uncoating) processes are critical for the HIV-1 replication. HIV-1 capsid (CA) and human cyclophilin A (CypA) play essential roles in these processes. We designed and synthesized a series of thiourea compounds as HIV-1 assembly and disassembly dual inhibitors targeting both HIV-1 CA protein and human CypA. The SIV-induced syncytium antiviral evaluation indicated that all of the inhibitors displayed antiviral activities in SIV-infected CEM cells at the concentration of 0.6-15.8 muM for 50% of maximum effective rate. Their abilities to bind CA and CypA were determined by ultraviolet spectroscopic analysis, fluorescence binding affinity and PPIase inhibition assay. Assembly studies in vitro demonstrated that the compounds could potently disrupt CA assembly with a dose-dependent manner. All of these molecules could bind CypA with binding affinities (Kd values) of 51.0-512.8 muM. Fifteen of the CypA binding compounds showed potent PPIase inhibitory activities (IC50 values < 1 muM) while they could not bind either to HIV-1 Protease or to HIV-1 Integrase in the enzyme assays. These results suggested that 15 compounds could block HIV-1 replication by inhibiting the PPIase activity of CypA to interfere with capsid disassembly and disrupting CA assembly. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 57319-65-0 is helpful to your research. Synthetic Route of 57319-65-0

Investigation of various N-heterocyclic substituted piperazine versions of 5/7-{[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-ol: Effect on affinity and selectivity for dopamine D3 receptor

Here we report on the design and synthesis of several heterocyclic analogues belonging to the 5/7-{[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-ol series of molecules. Compounds were subjected to [3H]spiperone binding assays, carried out with HEK-293 cells expressing either D2 or D3 dopamine receptors, in order to evaluate their inhibition constant (Ki) at these receptors. Results indicate that N-substitution on the piperazine ring can accommodate various substituted indole rings. The results also show that in order to maintain high affinity and selectivity for the D3 receptor the heterocyclic ring does not need to be connected directly to the piperazine ring as the majority of compounds included here are linked either via an amide or a methylene linker to the heterocyclic moiety. The enantiomers of the most potent racemic compound 10e exhibited differential activity with (-)-10e (Ki; D2 = 47.5 nM, D3 = 0.57 nM) displaying higher affinity at both D2 and D3 receptors compared to its enantiomer (+)-10e (Ki; D2 = 113 nM, D3 = 3.73 nM). Additionally, compound (-)-10e was more potent and selective for the D3 receptor compared to either 7-OH-DPAT or 5-OH-DPAT. Among the bioisosteric derivatives, the indazole derivative 10g and benzo[b]thiophene derivative 10i exhibited the highest affinity for D2 and D3 receptors. In the functional GTPgammaS binding study, one of the lead molecules, (-)-15, exhibited potent agonist activity at both D2 and D3 receptors with preferential affinity at D3.

WATER-SOLUBLE FLUORO-SUBSTITUTED CYANINE DYES AS REACTIVE FLUORESCENCE LABELLING REAGENTS

Disclosed are cyanine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which at least one of groups R1, R2, R3, R4, R5, R6, R7, R8, R9, R10 R11, R12, R13 and R14 is -L-M or -L-P, where L is a linking group, M is a target bonding group and P is a conjugated component, and at least one of groups R3, R4, R5, R6, R7, R8, R9 and R10 comprises fluorine. The use of cyanine dyes substituted by fluorine and having additional substitution with three or more sulphonic acid groups for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions. The dyes of the present invention are particularly useful in assays involving fluorescence detection where continual or repeated excitation is a requirement, for example in kinetic studies, or in microarray analyses where microarray slides may need to be reanalysed over a period of days.
