The inability to reliably replicate mitochondrial DNA (mtDNA) by mitochondrial DNA polymerase gamma (POLG) leads to a subset of common mitochondrial diseases associated with neuronal death and depletion of neuronal mtDNA. Defining disease mechanisms in neurons remains difficult due to the limited access to human tissue. Using human induced pluripotent stem cells (hiPSCs), we generated functional dopaminergic (DA) neurons showing positive expression of dopaminergic markers TH and DAT, mature neuronal marker MAP2 and functional synaptic markers synaptophysin and PSD-95. These DA neurons were electrophysiologically characterized, and exhibited inward Na + currents, overshooting action potentials and spontaneous postsynaptic currents (sPSCs). POLG patient-specific DA neurons (POLG-DA neurons) manifested a phenotype that replicated the molecular and biochemical changes found in patient post-mortem brain samples namely loss of complex I and depletion of mtDNA. Compared to disease-free hiPSC-derived DA neurons, POLG-DA neurons exhibited loss of mitochondrial membrane potential, loss of complex I and loss of mtDNA and TFAM expression. POLG driven mitochondrial dysfunction also led to neuronal ROS overproduction and increased cellular senescence. This deficit was selectively rescued by treatment with N-acetylcysteine amide (NACA). In conclusion, our study illustrates the promise of hiPSC technology for assessing pathogenetic mechanisms associated with POLG disease, and that NACA can be a promising potential therapy for mitochondrial diseases such as those caused by POLG mutation.

Substance P 1-7 (SP1-7, Arg(1)-Pro(2)-Lys(3)-Pro(4)-Gln(5)-Gln(6)-Phe(7)) is the major bioactive metabolite formed after proteolytic degradation of the tachykinin substance P (SP). This heptapeptide often opposes the effects of the mother peptide. Hence, SP1-7 is having anti-inflammatory, anti-nociceptive and anti-hyperalgesic effects in experimental models. Despite all encouraging properties of SP1-7 its exact mode of action has not yet been elucidated which has hampered further development of this heptapeptide in drug discovery. Contrary to SP that mediates its biological activity via the NK-1 receptor, the N-terminal fragment SP1-7 acts through an unknown target that is distinct from all known opioid and tachykinin receptors. The SP1-7 amide 1 (Arg(1)-Pro(2)-Lys(3)-Pro(4)-Gln(5)-Gln(6)-Phe(7)-NH2) was previously shown to be superior to the endogenous SP1-7 in all experimental pain models where the two compounds were compared. Herein, we report that N-methylation scan of the backbone of the SP1-7 amide (1) results in peptides that are significantly less prone to undergo proteolysis in plasma from both mouse and human. However, with the two exceptions of the [MeLys(3)] SP1-7 amide (3) and the [MeGln(5)] SP1-7 amide (4), the peptides with a methyl group attached to the backbone are devoid of significant anti-allodynic effects after peripheral administration in the spared nerve injury (SNI) mouse model of neuropathic pain. It is suggested that the N-methylation does not allow these peptides to form the accurate bioactive conformations or interactions required for efficient binding to the macromolecular target. The importance of intact N-terminal Arg(1) and C-terminal Phe(7), anticipated to serve as address and message residues, respectively, for achieving the anti-allodynic effect is emphasized. Notably, the three heptapeptides: the SP1-7 amide (1), the [MeLys(3)] SP1-7 amide (3) amide and the [MeGln(5)] SP1-7 amide (4) are all considerably more effective in the SNI mouse model than gabapentin that is widely used in the clinic for treatment of neuropathic pain.

Preeclampsia (PE) is a hypertensive disorder of pregnancy and one of the leading contributors to both maternal and perinatal morbidity and mortality. Reliable diagnostic parameters unique to the disorder that accurately define and diagnose PE are currently unavailable. Recent studies have revealed that PE is accompanied by the accumulation of amyloidogenic deposits in the placenta and the presence of congophilic amyloid-like protein aggregates in the urine. Here, we evaluate the capability of an amyloid-targeting aryl cyano amide (ARCAM-1) fluorophore to identify PE patients from analysis of urine samples. Our results reveal that this probe can distinguish patients with PE from gestationally healthy patients and patients suffering from non-PE hypertension, highlighting the potential for amyloid-targeting fluorophores to help identify PE patients during pregnancy.

Kynurenic acid (KYNA, 4-oxoquinoline-2-carboxylic acid), an intermediate of the tryptophan metabolism, has been recognized to exert different neuroactive actions; however, the need of how it or its aminoalkylated amide derivative N-(2-(dimethylamino)ethyl)-3-(morpholinomethyl)-4-oxo-1,4-dihydroquinoline-2-carboxamide (KYNA-A4) exerts any effects on ion currents in excitable cells remains largely unmet. In this study, the investigations of how KYNA and other structurally similar KYNA derivatives have any adjustments on different ionic currents in pituitary GH(3) cells and hippocampal mHippoE-14 neurons were performed by patch-clamp technique. KYNA or KYNA-A4 increased the amplitude of M-type K+ current (I-K(M)) and concomitantly enhanced the activation time course of the current. The EC50 value required for KYNA- or KYNA-A4 -stimulated I-K(M) was yielded to be 18.1 or 6.4 mu M, respectively. The presence of KYNA or KYNA-A4 shifted the relationship of normalized I-K(M)-conductance versus membrane potential to more depolarized potential with no change in the gating charge of the current. The voltage-dependent hysteretic area of I-K(M) elicited by long-lasting triangular ramp pulse was observed in GH(3) cells and that was increased during exposure to KYNA or KYNA-A4. In cell-attached current recordings, addition of KYNA raised the open probability of M-type K+ channels, along with increased mean open time of the channel. Cell exposure to KYNA or KYNA-A4 mildly inhibited delayed-rectifying K+ current; however, neither erg-mediated K+ current, hyperpolarization-activated cation current, nor voltage-gated Na+ current in GH(3) cells was changed by KYNA or KYNA-A4. Under whole-cell, current-clamp recordings, exposure to KYNA or KYNA-A4 diminished the frequency of spontaneous action potentials; moreover, their reduction in firing frequency was attenuated by linopirdine, yet not by iberiotoxin or apamin. In hippocampal mHippoE-14 neurons, the addition of KYNA also increased the I-K(M) amplitude effectively. Taken together, the actions presented herein would be one of the noticeable mechanisms through which they modulate functional activities of excitable cells occurring in vivo.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 62009-47-6, Name is 2-Aminomalonamide, SMILES is O=C(C(C(N)=O)N)N, in an article , author is Su, Shao-Hua, once mentioned of 62009-47-6, Application In Synthesis of 2-Aminomalonamide.

To explore the biological properties of rosin derivatives, two dehydroabietic acid derivatives N-(5-dehydroabietyl-1,3,4-thiadiazole)-yl-pyridine-2-carboxamide (DTPC) and di-N-(5-dehydroabietyl-1,3,4-thiadiazole)-yl-pyridine-2,6-carboxamide (DDTPC) with 1,3,4-thiadiazole, pyridine and amide moieties were designed and synthesized according to superposition principle of activity group. They interact with calf thymus DNA (CT DNA) via intercalation based on the results of circular dichroism (CD) and fluorescence spectroscopy, DNA denaturation and viscosity studies. Fluorescence and CD spectral experiments indicate that they might be transported and stored by protein like bovine serum albumin (BSA). MTT assay was further carried out to examine their cytotoxicity, they both showed selective cytotoxicity and DTPC exhibited better cytotoxicity. The anti proliferative effect of DTPC toward A431 cell line was stronger than that of clinically used cisplatin and oxaliplatin. In addition, the cytotoxicity of DTPC and DDTPC was closely related with their DNA binding ability. (c) 2020 Published by Elsevier B.V.

Now introduce a scientific discovery about this category.

A segmented polyurethane elastomer (PU) was synthesized in poly(lactic acid) (PLA) melt by reactive processing. The isocyanate component was anticipated to react with the end-groups of PLA resulting in the formation of block-copolymers. The stoichiometry of the functional groups was optimized in the preliminary experiments. Two different processing methods were compared in the further experiments: conventional mixing of PU with PLA (PLA/PU), and reactive blending (PLA-b-PU). The comparison of the structure and properties of compatibilized reactive blends and conventional physical blends clearly shows the benefits of reactive processing. Coupling resulted in a finer dispersion of the particles in the matrix leading to better mechanical properties in the reactive blend. The successful synthesis of PEA-b-PU block copolymers was confirmed by NMR spectroscopy. The isocyanate component was found to react only with the hydroxyl end-groups of PLA, while the formation of amide and acylurea groups was not detected on the carboxyl end.

Enhanced tetracycline adsorption onto hydroxyapatite by Fe(III) incorporation

Contamination of tetracycline (TC) in surface and ground water has proven to be a serious environmental concern, due to the extensive usage and the relatively high solubility of TC in water. Iron-incorporated hydroxyapatite (Fe-HAP) with different iron contents was prepared to improve the dispersibility and TC removal from water. Results indicated that Fe-HAP had higher dispersion stability and greater adsorption ability for TC compared with virgin HAP. TC adsorption was found to increase with increasing temperature but decrease with increasing pH values. Addition of exogenous ions (Na+ and Ca2+) resulted in a decrease of TC adsorption due to electrostatic screening and the competitive effect. However, Cu2+ and humic acid could promote TC adsorption by acting as a bridge to form Fe-HAP-Cu2+-TC surface complex. Meanwhile humic acid can also improve adsorption through hydrogen-bonding between carboxylic, phenolic hydroxyl groups of humic acid and the electron donors (-OH/O-, -NH2) of TC. The peak variations of -C=O and -NH2 in tricarbonyl amide group and -C=O in phenolic deketone group in the FTIR spectra of TC equilibrated with Fe-HAP revealed that TC adsorption was attributed to surface complexation. This study, therefore, showed that Fe-HAP could be a promising adsorbent for the removal of TC from aqueous solution. (C) 2017 Elsevier B.V. All rights reserved.

Mixed-ligand complexes of tenoxicam drug with some transition metal ions in presence of 2,2 ‘-bipyridine: Synthesis, spectroscopic characterization, thermal analysis, density functional theory and in vitro cytotoxic activity

The Preparation and characterization of Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Y(III) mixed ligand metal complexes with the effective anti-inflammatory drug tenoxicam (Ten) and 2,2’-bipyridine (Bipy) have been informed in this study by using elemental analyses, FT-IR, UV-Vis., H-1 NMR, mass spectra, thermal analyses (TGA, DTG), molar conductance and magnetic moment. FT-IR and UV-Vis. spectra proved that Ten acts as a neutral bidentate ligand chelated to the metal ions via the pyridine-N and oxygen of carbonyl group of the amide moiety and Bipy chelated through the nitrogen atoms. The thermodynamic parameters (E*, Delta S*, Delta H* and Delta G*) were calculated by using Coats-Redfern and Horowitz- Metzger method from DTG curves. The antimicrobial activity for all compounds against various species of bacteria and fungi was investigated and the results ensured that Fe(III) complex is more active than all other complexes. The DFT calculations were carried out to understand the optimized molecular geometry for the compounds. All studied complexes considered as soft respect to the Ten, with G value varied from 11.236 to 16.949 eV and equal to 8.772eV for Ten. The anticancer activity was screened against cell culture of HCT-116 (human colorectal carcinoma), HepG2 (human hepatocellular carcinoma) and MCF-7 (human breast adenocarcinoma) for all compounds.

Pd-Catalyzed Suzuki-Miyaura Cross-Coupling of Pentafluorophenyl Esters

Although the palladium-catalyzed Suzuki-Miyaura cross-coupling of aryl esters has received significant attention, there is a lack of methods that utilize cheap and readily accessible Pd-phosphane catalysts, and can be routinely carried out with high cross-coupling selectivity. Herein, we report the first general method for the cross-coupling of pentafluorophenyl esters (pentafluorophenyl = pfp) by selective C-O acyl cleavage. The reaction proceeds efficiently using Pd(0)/phosphane catalyst systems. The unique characteristics of pentafluorophenyl esters are reflected in the fully selective cross-coupling vs. phenolic esters. Of broad synthetic interest, this report establishes pentafluorophenyl esters as new, highly reactive, bench-stable, economical, ester-based, electrophilic acylative reagents via acyl-metal intermediates. Mechanistic studies strongly support a unified reactivity scale of acyl electrophiles by C(O)-X (X = N, O) activation. The reactivity of pfp esters can be correlated with barriers to isomerization around the C(acyl)-O bond.
