The beta2 Integrin Mac-1 Induces Protective LC3-Associated Phagocytosis of Listeria monocytogenes

The intracellular pathogen Listeria monocytogenes (L.m.) is targeted by the autophagic machinery, but the molecular mechanisms involved and consequences for anti-listerial immunity remain enigmatic. Here, we demonstrate that L.m. infection of macrophages in vivo exclusively evokes LC3-associated phagocytosis (LAP), but not canonical autophagy, and that targeting of L.m. by LAP is required for anti-listerial immunity. The pathway leading to LAP induction in response to L.m. infection emanates from the beta2 integrin Mac-1 (CR3, integrin alphaMbeta2), a receptor recognizing diverse microbial ligands. Interaction of L.m. with Mac-1 induces acid sphingomyelinase-mediated changes in membrane lipid composition that facilitate assembly and activation of the phagocyte NAPDH oxidase Nox2. Nox2-derived reactive oxygen species then trigger LC3 recruitment to L.m.-containing phagosomes by LAP. By promoting fusion of L.m.-containing phagosomes with lysosomes, LAP increases exposure of L.m. to bactericidal acid hydrolases, thereby enhancing anti-listerial activity of macrophages and immunity of mice. Listeria monocytogenes are targeted by the autophagic machinery via unclear molecular mechanisms. Gluschko and Herb et al. demonstrate that LC3-associated phagocytosis, but not canonical autophagy, is required for elimination of L. monocytogenes by macrophages and activated by the beta2 integrin Mac-1 (CR3, integrin alphaMbeta2).

Skap2 is required for defense against k. Pneumoniae infection and neutrophil respiratory burst

Klebsiella pneumoniae is a respiratory, blood, liver, and bladder pathogen of significant clinical concern. We show that the adaptor protein, SKAP2, is required for protection against K. pneumoniae (ATCC 43816) pulmonary infections. Skap2-/-mice had 100-fold higher bacterial burden when compared to wild-type and burden was controlled by SKAP2 expression in innate immune cells. Skap2-/-neutrophils and monocytes were present in infected lungs, and the neutrophils degranulated normally in response to K. pneumoniae infection in mice; however, K. pneumoniae-stimulated reactive oxygen species (ROS) production in vitro was abolished. K. pneumoniae-induced neutrophil ROS response required the activity of SFKs, Syk, Btk, PLC2, and PKCs. The loss of SKAP2 significantly hindered the K. pneumoniae-induced phosphorylation of SFKs, Syk, and Pyk2 implicating SKAP2 as proximal to their activation in pathogen-signaling pathways. In conclusion, SKAP2-dependent signaling in neutrophils is essential for K. pneumoniae-activated ROS production and for promoting bacterial clearance during infection.

Synthetic Approaches to Contemporary Drugs that Contain the Cyclopropyl Moiety

The U.S. Food and Drug Administration approved 18 new drugs that incorporate the cyclopropyl structural motif in the time frame from 2012 to 2018. This review provides an overview of synthetic approaches to these drugs with emphasis on the construction of the cyclopropyl moiety or its incorporation into the key building blocks for assembly of the highlighted drugs. Based on the structural diversity of these drugs, synthetic approaches for the construction and introduction of the cyclopropyl moiety into their structure are diverse and include: cycloalkylation (double alkylation) of CH-acids, catalytic cyclopropanation of alkenes with diazo compounds, the Simmons-Smith reaction, the Corey-Chaykovsky reaction, the Kulinkovich reaction, the Horner-Wadsworth-Emmons reaction, and cycloaddition. In addition, the cyclopropyl structure was also introduced into the drug substance intermediates via simple cyclopropyl-moiety-containing building blocks, such as cyclopropylamine, cyclopropanesulfonamide, cyclopropanecarbonyl chloride, and cyclopropylmagnesium bromide. 1 Introduction 2 Synthesis of Recently Approved Cyclopropyl-Moiety-Containing Drugs 2.1 Cabozantinib 2.2 Trametinib 2.3 Simeprevir 2.4 Ledipasvir 2.5 Olaparib 2.6 Tasimelteon 2.7 Finafloxacin 2.8 Paritaprevir 2.9 Lenvatinib 2.10 Lumacaftor 2.11 Lesinurad 2.12 Grazoprevir 2.13 Glecaprevir 2.14 Ozenoxacin 2.15 Voxilaprevir 2.16 Naldemedine 2.17 Tezacaftor 2.18 Tecovirimat 3 Conclusion.

Effect of small-molecule modification on single-cell pharmacokinetics of PARP inhibitors

The heterogeneous delivery of drugs in tumors is an established process contributing to variability in treatment outcome. Despite the general acceptance of variable delivery, the study of the underlying causes is challenging, given the complex tumor microenvironment including intra- and intertumor heterogeneity. The difficulty in studying this distribution is even more significant for small-molecule drugs where radiolabeled compounds or mass spectrometry detection lack the spatial and temporal resolution required to quantify the kinetics of drug distribution in vivo. In this work, we take advantage of the synthesis of fluorescent drug conjugates that retain their target binding but are designed with different physiochemical and thus pharmacokinetic properties. Using these probes,wefollowed the drug distribution in cell culture and tumor xenografts with temporal resolution of seconds and subcellular spatial resolution. These measurements, including in vivo permeability of small-molecule drugs, can be used directly in predictive pharmacokinetic models for the design of therapeutics and companion imaging agents as demonstrated by a finite element model.

Zinc(II) complexes with aromatic nitrogen-containing heterocycles as antifungal agents: Synergistic activity with clinically used drug nystatin

Three novel Zn(II) complexes, [ZnCl2(qz)2] (1), [ZnCl2(1,5-naph)]n (2) and [ZnCl2(4,7-phen)2] (3), where qz is quinazoline, 1,5-naph is 1,5-naphthyridine and 4,7-phen is 4,7-phenanthroline, were synthesized by the reactions of ZnCl2 and the corresponding N-heterocyclic ligand in 1:2 molar ratio in ethanol at ambient temperature. The characterization of these complexes was done by NMR, IR and UV?Vis spectroscopy, and their crystal structures were determined by single-crystal X-ray diffraction analysis. Complexes 1 and 3 are mononuclear species, in which Zn(II) ion is tetrahedrally coordinated by two nitrogen atoms belonging to two qz or 4,7-phen ligands, respectively, and by two chloride anions, while complex 2 is a 1D coordination polymer that contains 1,5-naph as bridging ligand between two metal ions. In agar disc-diffusion assay, complexes 1?3 manifested good inhibitory activity against two investigated Candida strains (C. albicans and C. parapsilosis), while not inducing toxic effects on the healthy human fibroblast cell line (MRC-5). This activity was not fungicidal, as revealed by the broth microdilution assay, however complex 3 showed the ability to modulate Candida hyphae formation, which is an important process during infection and showed significant synergistic effect with clinically used antifungal polyene nystatin.

Trypanothione reductase and superoxide dismutase as current drug targets for Trypanosoma cruzi: An overview of compounds with activity against chagas disease

It has been over a century since Carlos Chagas discovered the Trypanosoma cruzi (T. cruzi) as the causative agent of Chagas disease (CD), a neglected tropical disease with several socioeconomic, epidemiological and human health repercussions. Currently, there are only two commercialized drugs to treat CD in acute phase, nifurtimox and benznidazol, with several adverse side effects. Thus, new orally available and safe drugs for this parasitic infection are urgently required. One strategy of great importance in new drug discovery programmes is based on the search of molecules enabling to interfere with enzymes involved in T. cruzi metabolism. This review will focus on two of the most promising targets for the therapy of CD: trypanothione reductase (TR) and the iron-containing superoxide dismutase (Fe-SOD), which protect the parasite against oxidative damage by reactive oxygen species. A brief comparison of the function, mechanism of action and the active sites between T. cruzi TR and Fe-SOD with their analogues enzymes in human, glutathione reductase (GR) and the corresponding SODs, will be discussed. This review will also summarize the recent development and structure-activity relationships of novel compounds reported for their ability to selectively inhibit these targets, aiming to define molecular bases in the search for new effective treatment of CD.

Uses of K2S2O8 in Metal-Catalyzed and Metal-Free Oxidative Transformations

Carbon-carbon/carbon-heteroatom bond formation via oxidative transformations is a heavily explored topic at the frontier of chemistry. Potassium persulfate (K2S2O8) has emerged as a cost-effective, suitable inorganic oxidant for a wide array of oxidative transformations, ranging from laboratory experiments to industrial processes. The current review provides a comprehensive coverage of oxidative transformations aided with K2S2O8 in the presence or absence of a transition-metal catalyst, critical assessment of the results, and underlying mechanisms. Organic chemists may find this review to be a useful guide for the expedient synthesis of new chemical entities, to formulate mechanistic manifolds involving the sulfate radical anion, or to design novel oxidative transformations. A detailed understanding of the unsolved mechanisms could further enrich the field.
