The leukocyte chemotactic receptor FPR2, but not the closely related FPR1, is sensitive to cell-penetrating pepducins with amino acid sequences descending from the third intracellular receptor loop

Lipidated peptides (pepducins) can activate certain G-protein coupled receptors (GPCRs) through a unique allosteric modulation mechanism involving cytosolic receptor domains. Pepducins with the amino acid sequence of the third intracellular loop of the neutrophil formyl peptide receptors (FPRs) as a common denominator were N-terminally conjugated with palmitic acid. F2Pal16, containing the 16 amino acids present in the third intracellular loop of FPR2, induced superoxide production in human neutrophils and the activity was sensitive to FPR2 antagonists. Cells over-expressing FPR2 were similarly responsive and responded with a transient increase in cytosolic calcium. No such effects were observed with the corresponding FPR1 pepducin. The peptide alone, lacking palmitic acid, did not activate neutrophils. A ten amino acid long pepducin F2Pal10, that was a more potent neutrophil activator than F2Pal16, was used for amino acid substitution studies. The sequences of FPR1 and FPR2 in the third intracellular loop differ by only two amino acids, and a pepducin with the FPR2-specific K231 replaced by the FPR1-specific Q231 lost all activity. The active F2Pal10 pepducin also triggered a response in cells expressing a mutated FPR2 with the third intracellular loop identical to that of FPR1. The data presented suggest that the same signaling pathways are activated when the signaling cascade is initiated by a classical receptor agonist (outside-in signaling) and when signaling starts on the cytosolic side of the membrane by a pepducin (inside-in signaling). A fundamental difference is also disclosed between the two neutrophil FPRs regarding their sensitivities to third intracellular loop pepducins.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 3682-14-2, you can also check out more blogs about3682-14-2

Herein, we report a mild protocol for metal-, photocatalyst-, and light-free Minisci C-H alkylation reactions of N-heteroarenes with alkyl oxalates derived from primary, secondary, and tertiary alcohols. The protocol uses environmentally benign persulfate as a stoichiometric oxidant and does not require high temperatures or large excesses of either of the substrates, making the procedure suitable for late-stage C-H alkylation of complex molecules.

An Intermolecular Azidoheteroarylation of Simple Alkenes via Free-Radical Multicomponent Cascade Reactions

Based upon a radical polar effect, an intermolecular azidoheteroarylation of simple alkenes via a metal-free radical multicomponent cascade process was achieved. It allows a mild, rapid, and step-economic access to a broad range of azidoalkylated heteroaromatics. Given the diversity in transformations of organic azides and medicinally privileged scaffolds of heteroarenes, this strategy enables efficient synthesis and late-stage derivatization of drugs and candidates.

Extracellular adenosine enhances the ability of PMNs to kill Streptococcus pneumoniae by inhibiting IL-10 production

Polymorphonuclear leukocytes (PMNs) are crucial for initial control of Streptococcus pneumoniae (pneumococcus) lung infection; however, as the infection progresses their persistence in the lungs becomes detrimental. Here we explored why the antimicrobial efficacy of PMNs declines over the course of infection. We found that the progressive inability of PMNs to control infection correlated with phenotypic differences characterized by a decrease in CD73 expression, an enzyme required for production of extracellular adenosine (EAD). EAD production by CD73 was crucial for the ability of both murine and human PMNs to kill S. pneumoniae. In exploring the mechanisms by which CD73 controlled PMN function, we found that CD73 mediated its antimicrobial activity by inhibiting IL-10 production. PMNs from wild-type mice did not increase IL-10 production in response to S. pneumoniae; however, CD73?/? PMNs up-regulated IL-10 production upon pneumococcal infection in vitro and during lung challenge. IL-10 inhibited the ability of WT PMNs to kill pneumococci. Conversely, blocking IL-10 boosted the bactericidal activity of CD73?/? PMNs as well as host resistance of CD73?/? mice to pneumococcal pneumonia. CD73/IL-10 did not affect apoptosis, bacterial uptake, and intracellular killing or production of antimicrobial neutrophil elastase and myeloperoxidase. Rather, inhibition of IL-10 production by CD73 was important for optimal reactive oxygen species (ROS) production by PMNs. ROS contributed to PMN antimicrobial function as their removal or detoxification impaired the ability of PMNs to efficiently kill S. pneumoniae. This study demonstrates that CD73 controls PMN antimicrobial phenotype during S. pneumoniae infection.

Pressure-induced irreversible amorphization of naphthalene and nitrogen-containing heteroaromatic compounds at room temperature

Pressure-induced irreversible chemical reactions of naphthalene, 2,3-naphthyridine (2,3-Nap), and 1,5-naphthyridine (1,5-Nap) were observed after compression (>16?18 GPa) at room temperature. Regardless of the initial materials, amorphous products in which sp3 carbon was formed were obtained after the samples were recovered at ambient pressure. The X-ray photoelectron spectroscopy (XPS) of the product from naphthalene indicated that the carbon sp3/sp2 ratio was much lower than that of benzene nanothreads. Nitrogen remained in the amorphous products from 1,5-Nap and 2,3-Nap and bonded to both sp3 and sp2 carbons.

Quantitation of lipid hydroperoxides using enhanced chemiluminescence

To determine lipid hydroperoxides, an analytical procedure was proposed based on enhanced chemiluminescence. The analytical system consisted of a lipid, Fe(II), and coumarin C-525, an enhancer of chemiluminescence. Lipid hydroperoxides were determined with spiked solutions using tert-butyl hydroperoxide as an internal standard. The analytical procedure provided a detection limit as low as 164 nM. Verification was performed by iodometric titration. The assay was used to determine total lipid hydroperoxides in food.

Chemical synthesis and in silico molecular modeling of novel pyrrolyl benzohydrazide derivatives: Their biological evaluation against enoyl ACP reductase (InhA) and Mycobacterium tuberculosis

In efforts to develop new antitubercular agents, we report here the synthesis of a series of novel pyrrole hydrazine derivatives. The molecules were evaluated against inhibitors of InhA, which is one of the key enzymes involved in type II fatty acid biosynthetic pathway of the mycobacterial cell wall as well as inhibitors of Mycobacterium tuberculosis H37Rv. The binding mode of compounds at the active site of enoyl-ACP reductase was explored using the surflex-docking method. The model suggests one or two H-bonding interactions between the compounds and the InhA enzyme. Some compounds exhibited good activities against InhA in addition to promising activities against M. tuberculosis.

Mouse aldehyde-oxidase-4 controls diurnal rhythms, fat deposition and locomotor activity

Aldehyde-oxidase-4 (AOX4) is one of the mouse aldehyde oxidase isoenzymes and its physiological function is unknown. The major source of AOX4 is the Harderian-gland, where the enzyme is characterized by daily rhythmic fluctuations. Deletion of the Aox4 gene causes perturbations in the expression of the circadian-rhythms gene pathway, as indicated by transcriptomic analysis. AOX4 inactivation alters the diurnal oscillations in the expression of master clock-genes. Similar effects are observed in other organs devoid of AOX4, such as white adipose tissue, liver and hypothalamus indicating a systemic action. While perturbations of clock-genes is sex-independent in the Harderian-gland and hypothalamus, sex influences this trait in liver and white-adipose-tissue which are characterized by the presence of AOX isoforms other than AOX4. In knock-out animals, perturbations in clock-gene expression are accompanied by reduced locomotor activity, resistance to diet induced obesity and to hepatic steatosis. All these effects are observed in female and male animals. Resistance to obesity is due to diminished fat accumulation resulting from increased energy dissipation, as white-adipocytes undergo trans-differentiation towards brown-adipocytes. Metabolomics and enzymatic data indicate that 5-hydroxyindolacetic acid and tryptophan are novel endogenous AOX4 substrates, potentially involved in AOX4 systemic actions.
