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.

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.

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.

Metal-, Photocatalyst-, and Light-Free Minisci C-H Alkylation of N-Heteroarenes with Oxalates

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. Notably, several pharmaceuticals and natural products could be functionalized or prepared with this protocol, thus demonstrating its utility.

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

Design, synthesis and biological evaluation of novel phthalazinone acridine derivatives as dual PARP and Topo inhibitors for potential anticancer agents

In this study, we designed and synthesized a series of phthalazinone acridine derivatives as dual PARP and Topo inhibitors. MTT assays indicated that most of the compounds significantly inhibited multiple cancer cells proliferation. In addition, all the compounds displayed Topo II inhibition activity at 10 mol/L, and also possessed good PARP-1 inhibitory activities. Subsequent mechanistic studies showed that compound 9a induced remarkable apoptosis and caused prominent S cell cycle arrest in HCT116 cells. Our study suggested that 9a inhibiting Topo and PARP concurrently can be a potential lead compound for cancer therapy.

A non-invasive, multi-target approach to treat diabetic retinopathy

Hyperglycemia invoke number of pathways resulting in development of diabetic retinopathy (DR), including protein kinase C activation, increased expression of VEGF, advanced glycation end product (AGEs) formation and activation of polyol pathway, among which the pathophysiology of aldose reductase (ALR2) of the polyol pathway is evident by more than a decade of research. Subtle involvement of ALR2 in invoking various pathways of diabetic complications has caused an increase in attention towards the identification of novel aldose reductase inhibitors (ARIs). Numerous ARIs of different classes were employed in the treatment of diabetic complications initially, but few came into light as drugs. Though no ALR2 inhibitor has been used for the treatment or control of DR, Epalrestat has been used worldwide for treating diabetic neuropathy. This review critically analyses different treatments available for diabetic retinopathy, their limitations and the importance of the development of novel inhibitors of ALR2 that could prevent progression of DR, by causing a direct or indirect effect on controlling factors associated with DR.

Nitric oxide and hydrogen sulfide regulation of ischemic vascular growth and remodeling

Ischemic vascular remodeling occurs in response to stenosis or arterial occlusion leading to a change in blood flow and tissue perfusion. Altered blood flow elicits a cascade of molecular and cellular physiological responses leading to vascular remodeling of the macro- and microcirculation. Although cellular mechanisms of vascular remodeling such as arteriogenesis and angiogenesis have been studied, therapeutic approaches in these areas have had limited success due to the complexity and heterogeneous constellation of molecular signaling events regulating these processes. Understanding central molecular players of vascular remodeling should lead to a deeper understanding of this response and aid in the development of novel therapeutic strategies. Hydrogen sulfide (H2S) and nitric oxide (NO) are gaseous signaling molecules that are critically involved in regulating fundamental biochemical and molecular responses necessary for vascular growth and remodeling. This review examines how NO and H2S regulate pathophysiological mechanisms of angiogenesis and arteriogenesis, along with important chemical and experimental considerations revealed thus far. The importance of NO and H2S bioavailability, their synthesis enzymes and cofactors, and genetic variations associated with cardiovascular risk factors suggest that they serve as pivotal regulators of vascular remodeling responses.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
