Gold-catalyzed oxidation of alkynes

Although both alkynes and alkenes form stable complexes with gold,[1] alkynes are selectively activated by gold(I) in the presence of alkenes or other functional groups.[2] This high alkynophilicity of gold(I) actually reflects the higher reactivity of-alkyne gold(I) complexes over-alkene gold(I) complexes toward attack by a wide range of nucleophiles,[ 3] which is the basis for the surge in activity for synthetic applications based on the selective activation of alkynes in complex molecular settings.[2,4-6] The gold-catalyzed oxidation of alkynes takes place with oxidants with a highly polar X+-O-bond, such as sulfoxides and amine N-oxides,[7,8] which attack thealkyne gold(I) complex in a process similar to the addition of alcohols and water to alkynes, one of the prototypical transformations catalyzed by gold.[9-11] This addition reaction gives preferentially or exclusively products of Markovnikov addition[12,13] and can be performed with low catalyst loadings.[14] Two reviews have been published very recently covering developments in the gold(I)-catalyzed oxidation of alkynes.[7,8].

Context-Dependent and Disease-Specific Diversity in Protein Interactions within Stress Granules

Stress granules (SGs) are transient ribonucleoprotein (RNP) aggregates that form during cellular stress and are increasingly implicated in human neurodegeneration. To study the proteome and compositional diversity of SGs in different cell types and in the context of neurodegeneration-linked mutations, we used ascorbate peroxidase (APEX) proximity labeling, mass spectrometry, and immunofluorescence to identify ?150 previously unknown human SG components. A highly integrated, pre-existing SG protein interaction network in unstressed cells facilitates rapid coalescence into larger SGs. Approximately 20% of SG diversity is stress or cell-type dependent, with neuronal SGs displaying a particularly complex repertoire of proteins enriched in chaperones and autophagy factors. Strengthening the link between SGs and neurodegeneration, we demonstrate aberrant dynamics, composition, and subcellular distribution of SGs in cells from amyotrophic lateral sclerosis (ALS) patients. Using three Drosophila ALS/FTD models, we identify SG-associated modifiers of neurotoxicity in vivo. Altogether, our results highlight SG proteins as central to understanding and ultimately targeting neurodegeneration. Interactions between stress granule proteins exist ahead of a stress response and candidate SG proteins modify disease phenotypes in vivo.

Synthesis of functionalized tetrasubstituted pyrazolyl heterocycles – A review

Heterocyclic chemistry constitutes an essential branch of organic chemistry and heterocycles are widely known to display an array of biological properties. Pyrazoles represent key structural motifs in heterocyclic chemistry and are present in a large number of biologically active molecules relevant to the pharmaceutical and agrochemical industries. Compounds incorporating the pyrazolyl structural unit are being developed in a wide variety of therapeutic areas including CNS, metabolic diseases, and oncology. The current review summarizes recent advances in the synthesis of tetrasubstituted pyrazoles. The contents are discussed in five sections: (a) 1,3-dipolar cycloadditions, (b) related 1,3-dipolar cycloadditions, (c) condensations, (d) allenylphosphonates, and (e) synthesis of fused pyrazole containing heterocycles.

In vitro activity and preliminary toxicity of various diamidine compounds against Trypanosoma evansi

Trypanosoma evansi is an animal pathogenic protozoan, causing a wasting disease called Surra, which is broadly distributed in a wide range of mammalian hosts. Chemotherapy is the most efficient control method, which depends on four drugs. Unfortunately, with the appearance of resistance to these drugs, their effective use is threatened, emphasising a need to find new drugs. Diamidines bind to the minor groove of DNA at AT-rich sites and exert their anti-trypanosomal activity by inhibiting one or more DNA dependent enzymes or by directly impeding the transcription process.In total, 67 novel diamidine compounds were tested in vitro to determine activity against an animal pathogenic Chinese kinetoplastic T. evansi strain. In comparison, a human pathogenic Trypanosoma brucei rhodesiense strain and a P2 transporter knock out of a Trypanosoma brucei brucei strain were also tested. All diamidine compounds tested in this study against T. evansi produced inhibitory concentration (IC50) values below 50nM. The results demonstrate that these compounds are highly active against T. evansi in vitro. In addition, preliminary in vivo toxicity tests were performed on all 67 diamidines with 69% of the compounds showing no acute toxicity at an intra-peritoneal dose of 100mg/kg.

FMNH2-dependent monooxygenases initiate catabolism of sulfonamides in Microbacterium sp. strain BR1 subsisting on sulfonamide antibiotics

We report a cluster of genes encoding two monooxygenases (SadA and SadB) and one FMN reductase (SadC) that enable Microbacterium sp. strain BR1 and other Actinomycetes to inactivate sulfonamide antibiotics. Our results show that SadA and SadC are responsible for the initial attack of sulfonamide molecules resulting in the release of 4-aminophenol. The latter is further transformed into 1,2,4-trihydroxybenzene by SadB and SadC prior to mineralization and concomitant production of biomass. As the degradation products lack antibiotic activity, the presence of SadA will result in an alleviated bacteriostatic effect of sulfonamides. In addition to the relief from antibiotic stress this bacterium gains access to an additional carbon source when this gene cluster is expressed. As degradation of sulfonamides was also observed when Microbacterium sp. strain BR1 was grown on artificial urine medium, colonization with such strains may impede common sulfonamide treatment during co-infections with pathogens of the urinary tract. This case of biodegradation exemplifies the evolving catabolic capacity of bacteria, given that sulfonamide bacteriostatic are purely of synthetic origin. The wide distribution of this cluster in Actinomycetes and the presence of traA encoding a relaxase in its vicinity suggest that this cluster is mobile and that is rather alarming.
