Pigment‐Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials

Chemistry–Methods, EarlyView.
A methodology has been developed to extract the colored organic fraction occluded within seashell biomineral waste. Applied to sea urchin skeletons, free polyhydroxylated naphthoquinone (PHNQ) pigments and PHNQ‐macromolecule complexes are isolated. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to

The Role of High‐Gradient Diffusion Nuclear Magnetic Resonance in Exploring Peculiarity of Water in Ionic Liquids Doped with Alkali Metals

Chemistry–Methods, EarlyView.
Applying high gradients during diffusion nuclear magnetic resonance experiments allows for the determination of isolated microenvironments in ternary solutions composed of an imidazolium‐based ionic liquid, water and alkali metal halide. Two separate water populations are detected, forming either the isolated solvent network or the first solvation ...

DRL‐Fit: Determining Rate Constants In Multistep Reactions From ESI‐MS Data

Chemistry–Methods, EarlyView.
DRL‐Fit is a Python program that can fit a kinetic model to delayed reactant labeling data from ESI‐MS experiments, allowing rate constants to be determined in a multistep reaction. Consequently, the concentrations of all the involved molecules can be determined. This is applied to the nitro‐Mannich reaction to showcase the capabilities and limitations

First‐in‐Human Study of Merotocin, a Short‐Acting Peptidic Oxytocin Receptor Agonist for Lactation Support

Clinical Pharmacology in Drug Development, EarlyView.
Abstract Endogenous oxytocin plays an important role in lactation, but its effectiveness as an exogenous galactagogue has been modest due to dose‐limiting side effects related to off‐target effects at the vasopressin V2 receptor. Merotocin (FE 202767) is a short‐acting peptidic oxytocin receptor agonist with the potential to aid mothers experiencing ...
