A differentially pumped dual linear quadrupole ion trap (DLQIT) mass spectrometer: A mass spectrometer capable of MSn experiments free from interfering reactions

A novel differentially pumped dual linear quadrupole ion trap (DLQIT) mass spectrometer was designed and built to facilitate tandem MS experiments free from interfering reactions. The instrument consists of two differentially pumped Thermo Scientific linear quadrupole ion trap (LQIT) systems that have been connected via an ion transfer octupole encased in a machined manifold. Tandem MS experiments can be performed in the front trap and then the resulting product ions can be transferred via axial ejection into the back trap for further, independent tandem MS experiments in a differentially pumped area. This approach allows the examination of consecutive collision-activated dissociation (CAD) and ion-molecule reactions without unwanted side reactions that often occur when CAD and ion-molecule reactions are examined in the same space. Hence, it greatly facilitates investigations of ion structures. In addition, the overall lower pressure of the DLQIT, as compared to commercial LQIT instruments, results in a reduction of unwanted side reactions with atmospheric contaminants, such as water and oxygen, in CAD and ion-molecule experiments.

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 58142-99-7 is helpful to your research. Application of 58142-99-7

Synthesis of both enantiomers of protoberberines via laterally lithiated (S)-4-isopropyl-2-(o-tolyl)-oxazolines

The addition of the laterally lithiated (S)-4-isopropyl-2-(o- tolyl)oxazoline (1) to 6,7-dimethoxy-3,4-dihydroisoquinoline (2) proceeded in modest diastereoselectivity. However, the addition products (3a) and (3b) were easily separated by column chromatography over silica gel. Acid-catalyzed lactamization of 3a and 3b followed by LiAlH4-reduction afforded the corresponding optically pure protoberberines (8a) and (8b), respectively. This procedure was successfully applied to the synthesis of both enantiomers of xylopinine and bharatamine.

Metabotropic and ionotropic glutamate receptors as potential targets for the treatment of alcohol use disorder

Emerging evidence indicates that dysfunctional glutamate neurotransmission is critical in the initiation and development of alcohol and drug dependence. Alcohol consumption induced downregulation of glutamate transporter 1 (GLT-1) as reported in previous studies from our laboratory. Glutamate is the major excitatory neurotransmitter in the brain, which acts via interactions with several glutamate receptors. Alcohol consumption interferes with the glutamatergic signal transmission by altering the functions of these receptors. Among the glutamate receptors involved in alcohol-drinking behavior are the metabotropic receptors such as mGluR1/5, mGluR2/3, and mGluR7, as well as the ionotropic receptors, NMDA and AMPA. Preclinical studies using agonists and antagonists implicate these glutamatergic receptors in the development of alcohol use disorder (AUD). Therefore, the purpose of this review is to discuss the neurocircuitry involving glutamate transmission in animals exposed to alcohol and further outline the role of metabotropic and ionotropic receptors in the regulation of alcohol-drinking behavior. This review provides ample information about the potential therapeutic role of glutamatergic receptors for the treatment of AUD.

Selective, C,C-double bond reduction of alpha,beta-unsaturated carbonyl compounds with cyclohexane using zeolites

Selective ionic hydrogenation of alpha,beta-unsaturated carbonyl compounds with alkanes (cyclohexane and others) was previously known to proceed only in superacidic conditions due to the necessity of dicationic, superelectrophilic activation of the enones. In present paper we disclose that H-form zeolites with acidity well below superacidity, are able however to induce the reduction of alpha,beta-unsaturated carbonyl compounds with cyclohexane in strong analogy to the “parent”, superacid mediated reactions. The probable interpretation of these results in terms of highly electrophilic (superelectrophilic) intermediates on the solid is discussed.

Highly efficient orange-red electroluminescence of iridium complexes with good electron mobility

Two iridium complexes with 1-(2,6-bis(trifluoromethyl)pyridin-4-yl)isoquinoline (tfmpiq) and 4-(2,6-bis(trifluoromethyl)pyridin-4-yl)quinazoline (tfmpqz) main ligands and a tetraphenylimidodiphosphinate (tpip) ancillary ligand were applied in organic light-emitting diodes (OLEDs). The introduction of quinazoline greatly influences the nature of the complex. The quantum yield and the electron mobility of Ir(tfmpqz)2(tpip) are much higher than those of Ir(tfmpiq)2(tpip) (Ir(tfmpiq)2(tpip): Phi: 0.47, mue: 8.93-9.47 ¡Á 10-6 cm2 V-1 s-1 under an electric field from 1040 (V cm-1)1/2 to 1300 (V cm-1)1/2; Ir(tfmpqz)2(tpip): Phi: 0.98, mue: 6.44-7.20 ¡Á 10-6 cm2 V-1 s-1 under an electric field from 1040 (V cm-1)1/2 to 1300 (V cm-1)1/2). In addition, the Ir(tfmpqz)2(tpip)-based device also displayed better performance than that using Ir(tfmpiq)2(tpip). Furthermore, with a europium complex, Eu(DBM)3phen (DBM = dibenzoylmethide; phen = 1,10-phenanthroline) as a sensitizer, the device based on Ir(tfmpqz)2(tpip) with a double emissive layer structure of ITO/MoO3 (3 nm)/TAPC (50 nm)/Ir(tfmpqz)2(tpip) (5 wt%):TcTa (10 nm)/Eu(DBM)3phen (0.2 wt%):Ir(tfmpqz)2(tpip) (5 wt%):26DCzPPy (10 nm)/TmPyPB (50 nm)/LiF (1 nm)/Al (100 nm) displayed the best performance with a maximum luminance of 129466 cd m-2, and a maximum current efficiency and a maximum power efficiency of 62.96 cd A-1 and 53.43 lm W-1, respectively, with low efficiency roll-off. The current efficiency still remains as high as 58.84 cd A-1 at a brightness of 1000 cd m-2 and 53.27 cd A-1 at a brightness of 5000 cd m-2. These results suggest that Ir(iii) complexes with quinazoline units are potential orange-red phosphorescent materials for OLEDs.

5-Aminoisoquinolin-1-one (5-AIQ), a water-soluble inhibitor of the poly(ADP-Ribose)polymerases (PARPs)

5-Aminoisoquinolin-1-one (5-AIQ) is a water-soluble inhibitor of the poly(ADPribose) polymerases (PARPs), lacking isoform-selectivity. Although of only moderate potency in vitro against PARP-1, it is highly active in many assays in cells and in models in vivo, indicating excellent uptake. Optimisation of the several synthetic sequences to 5-AIQ has led to development of a short and efficient route from 1-chloroisoquinoline. It has been used widely as a biochemical and pharmacological tool to study the effects of inhibition of the PARPs. It ameliorates the damage to cells and tissues following reperfusion of ischaemic tissue, showing significant protective activity in a rodent model of haemorrhagic shock at the remarkably low dose of 30 mug Kg-1. Protection is also seen in models of myocardial infarction, ischaemic kidney and liver disorders, stroke and organ transplantation. Inhibition of PARP-1 by 5-AIQ causes down-regulation of the activity of NF-kappaB, which then down-regulates the expression of several gene products. Thus 5-AIQ has anti-inflammatory activity in vivo, through modulating the expression of cytokines and adhesion molecules. This indirect inhibition of expression is relevant in the activity of 5-AIQ in models of arthritis, Parkinson’s disease, multiple sclerosis, spinal cord injury, periodontitis and inflammatory conditions of the lung. Inhibition of expression of matrix metalloproteinases and other factors gives rise to anti-angiogenic activity and to remarkable anti-metastatic activity in a mouse model. Thus, although it has been overtaken by other PARP-inhibiting drugs in the oncological clinic, 5-AIQ remains a valuable tool to study the roles of PARPs in health and in diverse diseases.

Photocatalytic C-H silylation of heteroarenes by using trialkylhydrosilanes

The efficient and selective C-H silylation of heteroarenes, especially the pharmaceutically relevant electron-deficient heteroarenes, represents a great challenge in organic synthesis. Herein we wish to report a distinctive visible light-promoted photocatalytic C-H silylation approach that enables the direct coupling of trialkylhydrosilanes with both electron-deficient and -rich heteroarenes as well as with cyano-substituted arenes in moderate to high yields and with good regioselectivity. The protocol features operational simplicity, mild reaction conditions, and the use of safe and readily available Na2S2O8, bis(trimethylsilyl) peroxide (BTMSPO) or iPr3SiSH as the radical initiators. Notably, the challenging bulky and inert trialkylhydrosilanes, such as (t-butyldimethyl)silane (tBuMe2SiH) and (triisopropyl)silane (iPr3SiH), work smoothly with the protocol. Moreover, despite the higher stability of tBuMe2Si silylation products, our studies revealed their great reactivity and versatility in diverse C-Si-based chemical transformations, providing an operationally simple, low-cost, and environmentally benign synthetic technology for molecule construction and elaboration.

Discovery of the cancer cell selective dual acting anti-cancer agent (Z)-2-(1H-indol-3-yl)-3-(isoquinolin-5-yl)acrylonitrile (A131)

Selective targeting of cancer cells over normal cells is a key objective of targeted therapy. However few approaches achieve true mechanistic selectivity resulting in debilitating side effects and dose limitation. In this work we describe the discovery of A131 (4a), a new agent with an unprecedented dual mechanism of action targeting both mitosis and autophagy. Compound 4a was first identified in a phenotypic screen in which HeLa cells treated with 4a manifested mitotic arrest along with formation of multiple vesicles. Further investigations showed that 4a causes an increase in mitotic marker pH3 and autophagy marker LC3. Importantly 4a induces cell death in cancer cells while sparing normal cells which regrow after 4a is removed. Dual activities against pH3 and LC3 markers are required for cancer cell selectivity. An extensive SAR investigation confirmed 4a as the optimal dual inhibitor with potency against a panel of 30 cancer cell lines (average antiproliferative GI50 1.5 muM). In a mouse model of paclitaxel-resistant colon cancer, 4a showed 74% tumor growth inhibition when administered at a dose of 20 mg/kg IP twice a day.

Asymmetric synthesis of isoquinoline derivatives from amino acids

Reaction of isoquinolines 1 with N-arylsulfonylamino acid fluorides 2 provides a highly stereoselective access to new dihydroimidazo[2,1-a] isoquinolin-3-ones 5 via intermediate N-acylisoquinolinium salts 3. Addition reactions to the enamine double bond, such as hydrogenation or epoxidation with dimethyldioxirane, leads to tetrahydroimidazo[2,1-a]isoquinoline-3-ones 6, 7 and oxiranes 8, respectively. Opening of the oxirane ring of the 8 with nucleophiles allows the synthesis of hydroxytetrahydroimidazo[2,1-a]isoquinolin- 3-ones 10 or 12 or of the polycyclic 1,4-dioxane 13 in high stereoselectivity. The regioselectivity of the oxiran ring opening depends on the kind of nucleophile and the conditions. Reaction of dihydroisoquinoline with O-TBDMS-mandelic acid chloride 15 leads to a tetrahydrooxazolo[2,3-a] isoquinoline 17 with opposite facial selectivity as compared with dihydroimidazo[2,1-a]isoquinolin-3-ones 5.
