Abstract:
The threat of a deliberate release of chemical nerve agents has underscored the need to continually improve field effective treatments for these types of poisonings. The oxime containing HLö-7 is a potential second-generation therapeutic reactivator. A synthetic process for HLö-7 is detailed with improvements to the DIBAL reduction and ion exchange steps. HLö-7 was visualized for the first time within the active site of human acetylcholinesterase and its relative ex vivo potency confirmed against various nerve agents using a phrenic nerve hemidiaphragm assay.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
