Soluble Epoxide Hydrolase Inhibition Attenuates Excitotoxicity Involving 14,15-Epoxyeicosatrienoic Acid-Mediated Astrocytic Survival and Plasticity to Preserve Glutamate Homeostasis

Astrocytes play pivotal roles in regulating glutamate homeostasis at tripartite synapses. Inhibition of soluble epoxide hydrolase (sEHi) provides neuroprotection by blocking the degradation of 14,15-epoxyeicosatrienoic acid (14,15-EET), a lipid mediator whose synthesis can be activated downstream from group 1 metabotropic glutamate receptor (mGluR) signaling in astrocytes. However, it is unclear how sEHi regulates glutamate excitotoxicity. Here, we used three primary rat cortical culture systems, neuron-enriched (NE), astrocyte-enriched glia-neuron mix (GN), and purified astrocytes, to delineate the underlying mechanism by which sEHi and 14,15-EET attenuate excitotoxicity. We found that sEH inhibitor 12-(3-adamantan-1-yl-ureido)-dodecanoic acid (AUDA) and 14,15-EET both attenuated N-methyl-D-aspartate (NMDA)-induced neurite damage and cell death in GN, not NE, cortical cultures. The anti-excitotoxic effects of 14,15-EET and AUDA were both blocked by the group 1 mGluR5 antagonist 2-methyl-6-(phenylethynyl)pyridine (MPEP), as were their protective effects against NMDA-disrupted perineuronal astrocyte processes expressing glutamate transporter-1 (GLT-1) and subsequent glutamate uptake. Knockdown of sEH expression also attenuated NMDA neurotoxicity in mGluR5- and GLT-1-dependent manners. The 14,15-EET/AUDA-preserved astroglial integrity was confirmed in glutamate-stimulated primary astrocytes along with the reduction of the c-Jun N-terminal kinase 1 phosphorylation, in which the 14,15-EET effect is mGluR5-dependent. In vivo studies validated that sEHi and genetic deletion of sEH (Ephx2-KO) ameliorated excitotoxic kainic acid-induced seizure, memory impairment, and neuronal loss while preserving GLT-1-expressing perineuronal astrocytes in hippocampal CA3 subregions. These results suggest that 14,15-EET mediates mGluR5-dependent anti-excitotoxicity by protecting astrocytes to maintain glutamate homeostasis, which may account for the beneficial effect of sEH inhibition in excitotoxic brain injury and diseases.

Role of L- and D-Menthol in the Glucuronidation and Detoxification of the Major Lung Carcinogen, NNAL

Menthol, which creates mint flavor and scent, is often added to tobacco in both menthol and nonmenthol cigarettes. A potent tobacco carcinogen, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), is extensively metabolized to its equally carcinogenic metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) as (R)-or (S)-NNAL enantiomers. NNAL is detoxified by UDP-glucuronosyltransferase (UGT) enzymes, with glucuronidation occurring on either NNAL’s pyridine ring nitrogen (NNAL-N-Gluc) or the chiral alcohol [(R)-or (S)-NNAL-O-Gluc]. To characterize a potential effect by menthol on NNAL glucuronidation, in vitro menthol glucuronidation assays and menthol inhibition of NNAL-Gluc formation assays were performed. Additionally, NNAL and menthol glucuronides (MG) were measured in the urine of smokers (n = 100) from the Southern Community Cohort Study. UGTs 1A9, 1A10, 2A1, 2A2, 2A3, 2B4, 2B7, and 2B17 all exhibited glucuronidating activity against both L-and D-menthol. In human liver microsomes, both L- and D-menthol inhibited the formation of each NNAL-Gluc, with a stereospecific difference observed between the formation of (R)NNAL-O-Gluc and (S)-NNAL-O-Gluc in the presence of D-menthol but not L-menthol. With the exception of three nonmenthol cigarette smokers, urinary MG was detected in all menthol and nonmenthol smokers, with L-MG comprising >98% of total urinary MG. Levels of urinary NNAL-N-Gluc were significantly (P < 0.05) lower among subjects with high levels of total urinary MG; no significant changes in free NNAL were observed. These data suggest that the presence of menthol could lead to increases in alternative, activating metabolic pathways of NNAL in tobacco target tissues, increasing the opportunity for NNAL to damage DNA and lead to the development of tobacco-related cancers. SIGNIFICANCE STATEMENT High levels of the major menthol metabolite, menthol-glucuronide, was observed in the urine of smokers of either menthol or nonmenthol cigarettes. The fact that a significant inverse correlation was observed between the levels of urinary menthol-glucuronide and NNAL-N-glucuronide, a major detoxification metabolite of the tobacco carcinogen, NNK, suggests that menthol may inhibit clearance of this important tobacco carcinogen.

Cationic PCP and PCN NHC Core Pincer-Type Mn(I) Complexes: From Synthesis to Catalysis

The coordination chemistry of NHC core pincer-type PCP and PCN ligands with a Mn(I) center was systematically investigated. The reaction of [Mn(CO)(5)Br] with free carbenes, conveniently prepared from the corresponding imidazolium salts and a strong base, leads to the initial formation of bidentate fac[MnBr(CO)(3) (kappa P-2,C,L)] complexes bearing a pending phosphine or pyridine donor extremity (L), which upon bromide abstraction, afford cationic [Mn(CO)(3)(kappa P-3,C,L)](OTf) derivatives exhibiting a meridional or a facial coordinating geometry of tridentate NHC core ligand depending on its relative flexibility. All bi- and tridentate Mn(I) complexes were characterized by X-ray diffraction analysis. The impact of the tridentate ligand structure on catalytic performance was illustrated in the Mn-catalyzed hydrogenation of acetophenone revealing fac-[Mn(CO)(3)(kappa P-3,C,N)](OTO based on a 5,6-membered metallacyclic architecture to be the most active, thus evidencing the role of the pyridine arm lability in the catalytic cycle.

Bidimensional H-Bond Network Promotes Structural Order and Electron Transport in BPyMPMs Molecular Semiconductor

The presence of a hydrogen bond (H-Bond) network has been proved to impact significantly the efficiency of organic light-emitting diode (OLED) devices by promoting molecular orientation and structural anisotropy in thin films. The design of specific compounds to control H-Bond network formation in an amorphous material, and hence to improve OLED performances, is needed. A successful example is given by the bi-pyridyl-based family n-type of organic semiconductors named BPyMPM. The experimental evidences demonstrate a surprisingly higher electron mobility in thin film composed of 4,6-bis(3,5-di(pyridine-4-yl)phenyl)-2-methylpyrimidine (B4PyMPM (B4)), which is almost two order of magnitude higher than mobility measured for very similar member of the family, 4,6-bis(3,5-di(pyridine-2-yl)phenyl)-2-methylpyrimidine (B2PyMPM (B2)). Herein, a comprehensive computational study is presented, wherein classical and ab initio methods are combined, to investigate the 2D H-Bond network in B4 and B2 thin films. The results indicate that B4 forms a larger number of intermolecular C-H center dot center dot center dot N H-Bonds that promote a higher orientational and positional order in B4 films, and superior electron transport properties.

Pyridine-Based Macrocyclic and Open Receptors for Urea

Pyridine-based macrocyclic and open receptors 1-4 have been designed, synthesized and characterized. The macrocycle 1 was characterized by single crystal X-ray spectroscopy. Compound 2 selectively binds and recognizes urea in CHCl3. Fluorescence spectroscopy shows that compound 2 selectively displays quenching of monomer emission followed by formation of an intramolecular excimer upon hydrogen bond mediated complexation of urea. This distinguishes urea from thiourea. The fluorometric detection of urea has also been performed with the open receptors 3 and 4 in CHCl3. The detailed study reveals the effectivity of 2 in fluorescence sensing of urea over the structures 3 and 4. The urea recognition properties of receptors were evaluated by H-1 NMR, fluorescence and UV-vis studies.

Use of Pyrimidine and Pyrazine Bridges as a Design Strategy To Improve the Performance of Thermally Activated Delayed Fluorescence Organic Light Emitting Diodes

We present a study of two isomeric thermally activated delayed fluorescence (TADF) emitters 9,9′-(sulfonylbis(pyrimidine-5,2-diyl))bis(3,6-di-tert-butyl-9H-carbazole) (pDTCz-DPmS) and 9,9′-(sulfonylbis(pyrazine-5,2-diyl))bis(3,6-di-tert-butyl-9H-carbazole) (pDTCz-DPzS). The use of pyrimidine and pyrazine as bridging units between the electron donor and acceptor moieties is found to be advantageous compared to the phenyl- (pDTCz-DPS) and pyridine-based analogues (pDTCz-3DPyS and pDTCz-2DPyS). Conformational modulation of the donor groups as a function of the bridge results in high photoluminescence quantum yields (Phi(PL) > 68%) and small energy gaps between singlet and triplet excited states (Delta E-ST < 160 meV). OLEDs using pDTCz-DPmS and pDTCz-DPzS as emitters exhibit blue and green electroluminescence, respectively, with higher maximum external quantum efficiencies (EQE(max) of 14% and 18%, respectively) and a reduced efficiency roll-off as compared to the reference devices using pDTCz-DPS, pDTCz-3DPyS, and pDTCz-2DPyS as the emitters. Our results provide a more complete understanding on the impact of the bridge structure in D-A-D TADF systems on the optoelectronic properties of the emitter and how the balance between color purity and EQE in the devices can be controlled, advancing the design strategies for TADF emitters.

Synthesis, characterization and catalytic activity of PEPPSI-type palladium-NHC complexes

Eight benzimidazolium salts (2a-h) with two nitrogen atoms substituted by various alkyl groups have been synthesized in high yields. The benzimidazolium salts were readily converted into the corresponding PEPPSItype palladium-NHC complexes (PEPPSI = pyridine-enhanced precatalyst preparation, stabilization, and initiation) (3a-h). The structures of all compounds were characterized by H-1 NMR, C-13 NMR, and IR spectroscopy as well as by elemental analysis techniques, which support the proposed structures. The catalytic activity of the PEPPSI-type palladium-NHC complexes was evaluated with respect to the direct C5-arylation of 2-substituted heteroaryl derivatives (thiophene, furan and thiazole) with various aryl bromides. This arylation occurs efficiently and selectively at the C5-position of the 2-substituted thiophene, furan and thiazole derivatives.

Three-Dimensional Carbon Electrocatalysts for CO2 or CO Reduction

A challenge in the electrochemical CO(2 )reduction reaction (CO2RR) is the lack of efficient and selective electrocatalysts to valuable chemicals. Hydrocarbons and valuable chemicals from the CO2RR have primarily been observed on metallic Cu. Here, 3D carbon electrocatalysts (diporphyrin molecules; i.e., Pacman) have been investigated as potential CO2RR electrocatalysts using density functional theory simulations. This work presents a molecular-level engineering strategy for the development of electrocatalysts toward hydro-carbons. The introduction of a second metal center in the diporphyrins on one hand serves as a proton transfer or CO adsorption site, providing the possibility for the formation of C-H and C-C bonds. On the other hand, the second metal center selectively stabilizes key intermediates like *CH2O, *OCH3, and *OCCHOH, leading to CH4 and C-2 species production. It has been found that Pacman (Pac) with Mn or Fe is able to produce CH4. Furthermore, Pac-CoNi, Pac-CoCu, and Pac-CoCo with pyridine coordination catalysts generate CH3OH, while Pac-CoCo might enable C-C coupling, forming C-2 species.
