Oral insulin delivery could change the life of millions of diabetic patients as an effective, safe, easy-to-use, and affordable alternative to insulin injections, known by an inherently thwarted patient compliance. Here, we designed a multistage nanoparticle (NP) system capable of circumventing the biological barriers that lead to poor drug absorpt...

Gold is a valuable metal that can be dissolved with common household chemicals as reported by Timo Repo et al. in their Research Article (e202117587). By applying catalytic iodine, aqueous hydrogen peroxide and 2‐mercaptobenzimidazol, gold promptly dissolves in ethanol. Catalytic reactions and environmentally benign solvents and reagents are the ba...

Magmas readily react with their wall-rocks forming metamorphic contact aureoles. Sulphurand possibly metal mobilization within these contact aureoles is essential in the formation o feconomic magmatic sulphide deposits. We performed heating and partial melting experiments on a black shale sample from the Paleoproterozoic Virginia Formation, which i...
Article
Well-established label in biomolecules analysis, fluorescein isothiocyanate is commercially available in its two different isomers with equal fluorescence sensitivity, differing in meta- vs. para-isothiocyanate position. It was found in this study that the stability of the isomers depends on the polarity of different solvents and the pyridine (stab...
Article

The synthesis of new types of furan-based compounds other than 5-hydroxymethylfurfural from glucose is a very attractive yet underexploited strategy. We report here a catalytic conversion of glucose with acetylacetone (acac) to furan-centered chemicals, 2-methyl-3-acetylfuran (MAF) and 1-(5-(1,2-dihydroxyethyl)-2-methylfuran-3-yl)ethan-1-one (DMAF)...
Article
Invited for the cover of this issue is the group of Timo Repo at the University of Helsinki. The image depicts a ligand‐exchange reaction as a battle between hummingbirds and golden birds, which represent two different thiol ligands. Read the full text of the article at 10.1002/chem.202101028. “Gold is a valuable component in electronic waste, but...
Article
Dissolution of elemental gold occurs promptly with two different thiol ligands that act in a cooperative manner. The reaction benefits from the dynamic coordination sphere of AuI species that enables the dissolution to proceed via ligand‐exchange reactions. The dissolution proceeds from left to right and the birds represent the different Au species...
Article
A new selective synthesis of novel quinoline carboxamides was developed by the N-alkylation reaction of methyl (2-oxo-1,2- dihydroquinolin-4-yl)-L-alaninate via phase transfer catalysis in a basic medium at room temperature. The compounds were obtained in excellent yields (70-90%) and characterized by ¹H, ¹³CNMR spectroscopy and mass spectra. In ad...

Development of new, environmentally benign dissolution methods for metallic gold is driven by needs in the circular economy. Gold is widely used in consumer electronics, but sustainable and selective dissolution methods for Au are scarce. Herein we describe a quantitative dissolution of gold in organic solution under mild conditions using hydrogen...

Breast cancer, with around 2 million new cases in 2019, is the second most common cancer worldwide and the second leading cause of cancer death among females. The aim of this work is to realize a targeting nanomedicine through the conjugation of LinTT1 peptide, a specific molecule targeting p32 protein overexpressed by breast cancer and cancer asso...

N-aryl-oxazolidinones is a prominent family of antimicrobials used for treating infections caused by clinically prevalent Gram-positive bacteria. Recently, boron-containing compounds have displayed intriguing potential in the antibiotic discovery setting. Herein, we report the unprecedented introduction of a boron-containing moiety such as an aryl...

Herein we report a unique method for preparing diaryl hydroxyl dicarboxylic acids in a diastereospecific manner. The three-component reaction occurs between amino acid, aromatic aldehyde and primary alcohol in alkaline solutions under micro-wave-assisted conditions. The dicarboxylic acids are isolated as sodium salts in high yields (up to 77%) by a...

Stanozolol (STZ) is a drug used to treat serious disorders like aplastic anemia and hereditary angioedema. It is also indicated as an adjunct therapy for the treatment of vascular disorders and growth failures. Encouraging results obtained using animal models demonstrated that STZ increases bone formation and mineralization, thus improving both den...
