Mass Spectrometry Reviews, EarlyView.Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Synthesis of Some Aminopicolinic Acids [PDF]
, 2012 Some aminopicolinic acid derivatives have been synthesized and fully characterized. These pyridine derivatives were 4-aminopicolinic acid, 4-(4-aminophenylethynyl) picolinic acid and 4-(3-aminophenylethynyl) picolinic acid. In addition to these compounds,

Copper(II) Inhibition of the SARS‐CoV‐2 Main Protease
Natural Sciences, EarlyView.Molecular Docking of Cu(II) Schiff‐Base Chelates to SARS‐CoV‐2 Mpro. Two distinct Cu(II) chelates (Cu(II)Lp and Cu(II)Lm) are shown docked within the active site pocket of the Mpro, interacting with key residues HIS 41 and CYS 145. ABSTRACT In an analysis of the structural stability of the coronavirus main protease (Mpro), we identified regions of the ...

Susceptibility functions for slow relaxation processes in supercooled liquids and the search for universal relaxation patterns [PDF]
, 2002 In order to describe the slow response of a glass former we discuss some distribution of correlation times, e.g., the generalized gamma distribution (GG) and an extension thereof (GGE), the latter allowing to reproduce a simple peak susceptibility such as of Cole-Davidson type as well as a susceptibility exhibiting an additional high frequency power ...

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
Icarus, 2019, 319, 685-700, 2018 The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...

Synthesis, characterisation and luminescent properties of lanthanide-organic polymers with picolinic and glutaric acids [PDF]
Three new lanthanide(III) complexes (Ln = Sm, Tb and Eu) of picolinic and glutaric acid were prepared and characterised. The crystal structure of the complex [Sm(glu)(pic)- (H2O)2] (where Hpic and H2glu stand for picolinic and glutaric acid ...

Catalytic and mechanistic studies into the epoxidation of styrenes using manganese complexes of structurally similar polyamine ligands [PDF]
, 2014 The synthesis and catalytic activity of manganese(ii) complexes of two polyamine ligands is reported which highlights how a small structural change in the ligand affects the overall catalytic behaviour.
