Abyssomicins—A 20-Year Retrospective View
Marine Drugs, 2021 Abyssomicins represent a new family of polycyclic macrolactones. The first described compounds of the abyssomicin family were abyssomicin B, C, atrop-C, and D, produced by the marine actinomycete strain Verrucosispora maris AB-18-032, which was isolated ...

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 ...

Chemistry – A European Journal, EarlyView.Herein, a sequential acyl‐thiol‐ene/S‐deacetylation protocol for selective installation of thiol residues onto synthetic peptides, on‐resin, is demonstrated. The hydrothiolation/S‐deacetylation protocol offers a novel synthetic tool for direct peptide conjugation on‐resin and for the preparation of novel disulfide containing neuropeptides displaying ...

ChemPhysChem, EarlyView.Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...

Electrochemical Science Advances, EarlyView.ABSTRACT Cancer is a result of uncontrolled cell growth with the potential to damage or spread to another part of the body. It is the deadliest disease in the world; therefore, rapid and sensitive detection is essential to fight it. In the past few decades, many diagnosis tools have been developed to detect cancer and monitor therapy progress.

Glia, EarlyView.The glial Na+ pump regulates [K+]o during neuronal activity, and the neuronal version restores [K+]o to baseline. Spreading depression‐related rise of K+ does not cause SD propagation via suppression of Na+/K+‐ATPase or glutamate transport. ABSTRACT Neuronal activity in the central nervous system is associated with a [K+]o transient that is swiftly ...
