Characterization of a Novel Human-Specific STING Agonist that Elicits Antiviral Activity Against Emerging Alphaviruses

Pharmacologic stimulation of innate immune processes represents an attractive strategy to achieve multiple therapeutic outcomes including inhibition of virus replication, boosting antitumor immunity, and enhancing vaccine immunogenicity. In light of this we sought to identify small molecules capable of activating the type I interferon (IFN) response by way of the transcription factor IFN regulatory factor 3 (IRF3). A high throughput in vitro screen yielded 4-(2-chloro-6-fluorobenzyl)-N-(furan-2-ylmethyl)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]thiazine-6-carboxamide (referred to herein as G10), which was found to trigger IRF3/IFN-associated transcription in human fibroblasts. Further examination of the cellular response to this molecule revealed expression of multiple IRF3-dependent antiviral effector genes as well as type I and III IFN subtypes. This led to the establishment of a cellular state that prevented replication of emerging Alphavirus species including Chikungunya virus, Venezuelan Equine Encephalitis virus, and Sindbis virus. To define cellular proteins essential to elicitation of the antiviral activity by the compound we employed a reverse genetics approach that utilized genome editing via CRISPR/Cas9 technology. This allowed the identification of IRF3, the IRF3-activating adaptor molecule STING, and the IFN-associated transcription factor STAT1 as required for observed gene induction and antiviral effects. Biochemical analysis indicates that G10 does not bind to STING directly, however. Thus the compound may represent the first synthetic small molecule characterized as an indirect activator of human STING-dependent phenotypes. In vivo stimulation of STING-dependent activity by an unrelated small molecule in a mouse model of Chikungunya virus infection blocked viremia demonstrating that pharmacologic activation of this signaling pathway may represent a feasible strategy for combating emerging Alphaviruses.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 7689-03-4, you can contact me at any time and look forward to more communication. Electric Literature of 7689-03-4.

Synthesis, spectroscopic characterization, and anticancer activity of new 10-substituted 1,6-diazaphenothiazines

New phenothiazine derivatives as 10-substituted dipyridothiazines of the 1,6-diazaphenothiazine structure were obtained in the cyclization reaction of 3-amino-3′-nitro-2,2′-dipyridinyl sulfide and 3,3′-dinitro-2,2′-dipyridinyl disulfide, and in the reaction of 2-chloro-3-ntropyridine with sodium 3-amino-2-pyridinethiolate followed by various alkylation and arylation reactions. The reaction of the thiazine ring formation ran via the Smiles rearrangement of the S-N type. As the alkylation reactions could proceed at the thiazine, azine or both nitrogen atoms, the product structure elucidation was based on the 2D NMR (Rotating-frame Overhauser Effect Spectroscopy, Correlated Spectroscopy, Heteronuclear Single Quantum Coherence, and Heteronuclear Multiple Bond Correlation) spectra of the N-methylated product. Some 10-substituted 1,6-diazaphenothizines (5, 10, 12, 13) were at least anticancer active against melanoma C-32 and breast cancer MCF-7 cell lines as a reference drug – cisplatin. The monoazaphenothiazine drug, prothipendyl, turned out to be less active than least 6 derivatives of the 1,6-diazaphenothiazine structure.

Dipyrimido[4,5-b:5,4-e][1,4]thiazine: synthesis and their enzyme inhibitory activity assessment on soybean 15-lipoxygenase

A series of new derivatives of dipyrimido[4,5-b:5,4-e][1,4] thiazine were synthesized by treatment of 5-amino-6-methyl-2-morpholino-4-pyrimidinethiol (1) with 5-bromo-2,4-dichloro-6-methylpyrimidine (2) in the presence of triethylamine and ethanol and subsequently with various secondary amines in EtOH/DMF. The thioether derivative 3 and heterocyclization products 4a-f were characterized by elemental analysis and spectroscopic techniques. The 15-LO inhibitory activities of the new synthesized compounds were also evaluated. The results show that compound 4e has the best IC50 of 15-LO inhibition (IC50 = 14.4 A mu M) but when all the products were theoretically docked into 15-LO, the GOLD scores of compounds 4e and 4d are 43.67 and 43.39 respectively, which show the best results. We suggest that the hydrogen bond interaction between Ser489 of 15-LO and the nitrogen of piperazine ring of compound 4e appears to play major role in lipoxygenase inhibition.

Oxicams Bind in a Novel Mode to the Cyclooxygenase Active Site via a Two-water-mediated H-bonding Network

Background: The oxicams are anti-inflammatory drugs targeting the cyclooxygenase enzymes. Results: Crystal complexes of mCOX-2isoxicam, mCOX-2meloxicam, and oCOX-1meloxicam are solved. Conclusion: Oxicams bind to the cyclooxygenase active sites in a novel mode. Significance: The first structural description of cyclooxygenase-oxicam complexes reveal a new binding pocket of inhibitors to cyclooxygenases. Oxicams are widely used nonsteroidal anti-inflammatory drugs (NSAIDs), but little is known about the molecular basis of the interaction with their target enzymes, the cyclooxygenases (COX). Isoxicam is a nonselective inhibitor of COX-1 and COX-2 whereas meloxicam displays some selectivity for COX-2. Here we report crystal complexes of COX-2 with isoxicam and meloxicam at 2.0 and 2.45 angstroms, respectively, and a crystal complex of COX-1 with meloxicam at 2.4 angstroms. These structures reveal that the oxicams bind to the active site of COX-2 using a binding pose not seen with other NSAIDs through two highly coordinated water molecules. The 4-hydroxyl group on the thiazine ring partners with Ser-530 via hydrogen bonding, and the heteroatom of the carboxamide ring of the oxicam scaffold interacts with Tyr-385 and Ser-530 through a highly coordinated water molecule. The nitrogen atom of the thiazine and the oxygen atom of the carboxamide bind to Arg-120 and Tyr-355 via another highly ordered water molecule. The rotation of Leu-531 in the structure opens a novel binding pocket, which is not utilized for the binding of other NSAIDs. In addition, a detailed study of meloxicamCOX-2 interactions revealed that mutation of Val-434 to Ile significantly reduces inhibition by meloxicam due to subtle changes around Phe-518, giving rise to the preferential inhibition of COX-2 over COX-1.

Laccase mediator system obtained from a marine spore exhibits decolorization potential in harsh environmental conditions

Laccases play a significant role in remedying dye pollutants. Most of these enzymes are originated from terrestrial fungi and bacteria, thus they are not proper to be used in the environments with neutral/alkaline pH, or they may require laborious extraction/purification steps. These limitations can be solved using marine spore laccases through high stability and easy to use application. In the current study, laccase activity of the marine spore-forming Bacillus sp. KC2 was measured according to the guaiacol and syringaldazine oxidation. Abiotic stresses like pH of 6, temperature of 37 degrees C and 0.3 mM CuSO4 (in comparison with optimal sporulation conditions: pH of 8, temperature of 20 degrees C and 0.0 mM CuSO4) enhanced laccase formation in sporal coat. Maximum activity of enzyme was observed at 50 degrees C and pH 7, which did not change in the alkaline pH and temperature range of 20-70 degrees C. Results indicated ions, inhibitors and solvent stability of the enzyme and its activity were stimulated by Co2+, Mn2+, PMSF, acetone, acetonitrile, ethanol, and methanol. The spore laccase could decolorize synthetic dyes from various chemical groups including azo (acid orange, amaranth, trypan blue, congo red, and amido black), indigo (indigo carmine), thiazine (methylene blue, and toluidine blue), and triarylmethane (malachite green) with ABTS/syringaldazine mediators after 5 h. Degradation products were not toxic against Sorghum vulgare and Artemia sauna model organisms. The enzyme mediator system showed high potentials for dye bioremediation over a wide range of harsh conditions.

Visible-light photocatalytic activation of N-chlorosuccinimide by organic dyes for the chlorination of arenes and heteroarenes

A variety of arenes and heteroarenes are chlorinated in moderate to excellent yields using N-chlorosuccinimide (NCS) under visible-light activated conditions. A screening of known organic dye photocatalysts resulted in the identification of methylene green as the most efficient catalyst to use with NCS. According to mechanistic studies described within, the reaction is speculated to proceed via a single electron oxidation of NCS utilizing methylene green under visible-light photoredox pathway. The photooxidation of NCS amplifies the electrophilicity of the chlorine atom of the NCS, thus leading to enhanced reactivity as a chlorinating reagent with aromatic substrates.

Pressure-Enhanced C-H Bond Activation in Chloromethane Platinum(II) Complexes

The nature of the interaction between chloromethanes CH4-nCln and Pt(II) complexes has been studied by high-pressure X-ray diffraction and infrared spectroscopy in combination with DFT calculations. In case of electron rich complexes such as d(8)-Pt(btz-N,N ‘)(phenyl)L with L = phenyl, Cl, Br and btz = 2,2 ‘-Bi-5,6-dihydro-4H-1,3-thiazine stable chloroform adducts with bridging hydrogen atoms in the eta(1)(C-H)Pt moieties were isolated which display highly activated C-H bonds. This activation is a consequence of a pronounced Pt(d(z2))->sigma*(C-H) back donation and is signaled by large red-shifts of the isolated nu(is)(C-H) stretching modes. The extent of the C-H bond activation and covalent Pt-H bond formation in the eta(1)(C-H)Pt moieties is thereby controlled by (i) the sigma/pi donor capabilities of the ligands L, (ii) the orientation of the coordinating C-H bond with regard to the Pt(d(z2)) orbital and (iii) the applied pressure.

Safety of Campathecin, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 7689-03-4 is helpful to your research.

Environment effects on the nonlinear absorption properties of Methylene blue under different power of excitation beam

In this paper, the nonlinear optical absorption properties of Methylene blue solutions were studied by open aperture Z-scan technique under a continuous-wave laser irradiation with various input powers. The experimental results show that the mechanism of nonlinear absorption and the calculated coefficients depend highly onthe molecular surrounding media properties and the nature of intermolecular interactions. From the experimental results, the contributions of various intermolecular interactions were determined as well. Exploiting these results, it is possible to determine the effective media polarity parameters on the nonlinear responses of optical materials. According to the experimental results, by increasing of excitation beam power, the strong hydrogen bonds with high contributions increase the third order nonlinear responses of Methylene blue molecules.
