Staphylococcal superantigen-like protein 13 activates neutrophils via formyl peptide receptor 2

Staphylococcal superantigen-like (SSL) proteins, one of the major virulence factor families produced by Staphylococcus aureus, were previously demonstrated to be immune evasion molecules that interfere with a variety of innate immune defences. However, in contrast to characterised SSLs, which inhibit immune functions, we show that SSL13 is a strong activator of neutrophils via the formyl peptide receptor 2 (FPR2). Moreover, our data show that SSL13 acts as a chemoattractant and induces degranulation and oxidative burst in neutrophils. As with many other staphylococcal immune evasion proteins, SSL13 shows a high degree of human specificity. SSL13 is not able to efficiently activate mouse neutrophils, hampering in vivo experiments. In conclusion, SSL13 is a neutrophil chemoattractant and activator that acts via FPR2. Therefore, SSL13 is a unique SSL member that does not belong to the immune evasion class but is a pathogen alarming molecule. Our study provides a new concept of SSLs; SSLs not only inhibit host immune processes but also recruit human neutrophils to the site of infection. This new insight allows us to better understand complex interactions between host and S.?aureus pathological processes.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3682-14-2, help many people in the next few years.Recommanded Product: 3682-14-2

Alkyl Carbazates for Electrochemical Deoxygenative Functionalization of Heteroarenes

The C?O bond cleavage for activation of alcohols is synthetically useful and practically challenging. This work describes carbazate as a new type of electrochemically activated alkylating agent derived from ubiquitous alcohols for direct functionalization of heteroarenes under mild electrolytic conditions. The simple undivided cell at low oxidative potentials with carbon/platinum electrode set-ups offers excellent substrate tolerance, affording a variety of primary, secondary and tertiary alkyl-decorated heterocycles in good chemical yields. Furthermore, the mechanism for this electrochemical deoxyalkylation reaction has been investigated.

An experimental and theoretical study of molecular structure and vibrational spectra of 2-chloronicotinic acid by density functional theory and ab initio Hartree-Fock calculations

In this work, the Fourier transform Raman and Fourier transform infrared spectra of 2-chloronicotinic acid (2-CNA) are recorded in the solid phase. The molecular geometry, vibrational frequencies, infrared intensities and Raman scattering activities of 2-CNA in ground state have been calculated by using ab initio Hartree-Fock (HF) and density functional (B3LYP and B3PW91) methods with 6-31G(d) and 6-311G(d) basis sets level. On the basis of the comparison between calculated and experimental results and the comparison with related molecule, assignments of fundamental vibrational modes are examined. The optimized geometric parameters (bond lengths and bond angles) obtained by using HF show the best agreement with the experimental values of 2-CNA. Comparison of the observed fundamental vibrational frequencies of 2-CNA and calculated results by density functional (B3LYP and B3PW91) and Hartree-Fock methods indicates that B3LYP is superior to the scaled Hartree-Fock and B3PW91 approach for molecular vibrational problems.

Induction of an anti-inflammatory human monocyte subtype is a unique property of glucocorticoids, but can be modified by IL-6 and IL-10

Glucocorticoids (GC) are the most widely used immunosuppressive agents in clinical medicine. Recently we showed that GC enhance survival of human monocytes and induce a specific anti-inflammatory monocyte subtype which actively induces resolution of inflammation.We now investigated if cytokines IL-4, IL-6 and IL-10, which, like GC, have mostly anti-inflammatory effects on macrophages, would have GC-like effects also on monocytes.Human monocytes were stimulated with either cytokine, GC or combination thereof, and resulting effects on apoptosis, adherence, migration, phagocytosis, ROS production and cell surface phenotype were determined. We found that IL-4, IL-6, and IL-10 had either less or different effects on various anti-inflammatory functions of monocytes compared to GC. As such, IL-4 and IL-6 alone did not delay apoptosis while IL-10 even enhanced it. However, IL-6 or IL-10 increased GC-mediated protection from apoptosis when applied together with GC.Thus, the potential of GC to induce anti-inflammatory human monocytes is unique and not mimicked by the investigated cytokines. However, IL-6 and IL-10 amplify GC-induced anti-inflammatory and pro-resolution mechanisms by enhancing survival of GC-induced monocytes and thus sustaining their function. This combined effect of GC and cytokines could be important for the physiological switch from amplification towards resolution phase of inflammation.

Rhodium(III)-Catalyzed C-H Functionalization of 1-(2H)-Phthalazinones at C8

The rhodium(III) catalyst tris(acetonitrile)pentamethylcyclopentadienylrhodium(III) hexafluoroantimonate ([Cp*Rh(MeCN)3](SbF6)2) reacts with 1-(2H)-phthalazinones to promote a C-H functionalization event at C8. Preparation of a set of compounds arising from oxidative alkenylation with olefins, hydroarylation with alkynes, and iodination with N-iodosuccinimide is reported here. Oxidative alkenylation proceeds in very good yield, and the scope and limitations of the hydroarylation and halogenation reactions are discussed. Notably, this strategy enables rapid preparation of C8-substituted phthalazinones without requiring phthalazinone ring synthesis starting from a prefunctionalized arene.

In vitro drug-drug interaction potential of sulfoxide and/or sulfone metabolites of albendazole, triclabendazole, aldicarb, methiocarb, montelukast and ziprasidone

Background: The use of polypharmacy in the present day clinical therapy has made the identification of clinical drug-drug interaction risk an important aspect of drug development process. Although many drugs can be metabolized to sulfoxide and/or sulfone metabolites, seldom is known on the CYP inhibition potential and/or the metabolic fate for such metabolites. Objective: The key objectives were: a) to evaluate the in vitro CYP inhibition potential of selected parent drugs with sulfoxide/sulfone metabolites; b) to assess the in vitro metabolic fate of the same panel of parent drugs and metabolites. Methods: In vitro drug-drug interaction potential of test compounds was investigated in two stages; 1) assessment of CYP450 inhibition potential of test compounds using human liver microsomes (HLM); and 2) assessment of test compounds as substrate of Phase I enzymes; including CYP450, FMO, AO and MAO using HLM, recombinant human CYP enzymes (rhCYP), Human Liver Cytosol (HLC) and Human Liver Mitochondrial (HLMit). All samples were analysed by LC-MS-MS method. Results: CYP1A2 was inhibited by methiocarb, triclabendazole, triclabendazole sulfoxide, and ziprasidone sulfone with IC50 of 0.71 muM, 1.07 muM, 4.19 muM, and 17.14 muM, respectively. CYP2C8 was inhibited by montelukast, montelukast sulfoxide, montelukast sulfone, tribendazole, triclabendazole sulfoxide, and triclabendazole sulfone with IC50 of 0.08 muM, 0.05 muM, 0.02 muM, 3.31 muM, 8.95 muM, and 1.05 muM, respectively. CYP2C9 was inhibited by triclabendazole, triclabendazole sulfoxide, triclabendazole sulfone, montelukast, montelukast sulfoxide and montelukast sulfone with IC50 of 1.17 muM, 1.95 muM, 0.69 muM, 1.34 muM, 3.61 muM and 2.15 muM, respectively. CYP2C19 was inhibited by triclabendazole and triclabendazole sulfoxide with IC50 of 0.25 and 0.22, respectively. CYP3A4 was inhibited by montelukast sulfoxide and triclabendazole with IC50 of 9.33 and 15.11, respectively. Amongst the studied sulfoxide/sulfone substrates, the propensity of involvement of CY2C9 and CYP3A4 enzyme was high (approximately 56% of total) in the metabolic fate experiments. Conclusion: Based on the findings, a proper risk assessment strategy needs to be factored (i.e., perpetrator and/or victim drug) to overcome any imminent risk of potential clinical drug-drug interaction when sulfoxide/sulfone metabolite(s) generating drugs are coadministered in therapy.

Reactions of phthalazine, quinazoline, 4,7-phenanthroline and 2,3?-bipyridine with ruthenium carbonyl

The reactions of [Ru3(CO)12] with four aromatic diazines have been studied in THF at reflux temperature. With phthalazine (L1), the compound [Ru3(mu-kappa2N 2N3-L1)(mu-CO)3(CO)7] (1), which contains an intact phthalazine ligand in an axial position bridging an Ru-Ru edge through both N atoms, is initially formed but it reacts with more phthalazine to give [Ru3(kappaN2-L1)(mu- kappa2N2N3-L1)(mu-CO) 3(CO)6] (2), in which a pi-pi stacking interaction between the aromatic rings of both ligands determines their position in cluster axial sites on the same face of the Ru3 triangle. With quinazoline (HL2), the cyclometalated hydrido decacarbonyl derivative [Ru 3(mu-H)(mu-kappa2N3C4-L 2)(CO)10] (3) is initially produced but it partially decarbonylates under the reaction conditions to give [Ru6(mu-H) 2(mu-kappa2N3C4-L 2)(mu3-kappa3-N1N 3C4-L2)(CO)19] (4), which results from the displacement of a CO ligand of 3 by the uncoordinated N1 atom of another molecule of 3. With 4,7-phenanthroline (H2L 3), the stepwise formation of the cyclometalated derivatives [Ru 3(mu-H)(mu-kappa2N4C3-HL 3)(CO)10] (5) and two isomers of [Ru6(mu-H) 2(mu4-kappa4N4C 3N7C8-L3)(CO)20] (6a, 6b) takes place. In compounds 6a and 6b, two Ru3(mu-H)(CO) 10 trinuclear units are symmetrically (C2 in 6a or C S in 6b) bridged by a doubly-cyclometalated 4,7-phenanthroline ligand. With 2,3?-bipyridine (HL4), two products have been isolated, [Ru3(mu-H)(mu-kappa2N 3?C4?-L4)(CO)10] (7) and [Ru3(mu-H)(mu-kappa3N2N 3?C2?-L4)(CO)9] (8). While compound 7 contains an N3?C4?- cyclometalated 2,3?-bipyridine, in compound 8 an N 3?C2?-cyclometalation is accompanied by the coordination of the N2 atom of the remaining pyridine fragment. The structures of compounds 2, 3, 4, 6a and 8 have been determined by X-ray diffraction crystallography.
