Less than 2% of all potential neurotherapeutics cross the blood-brain barrier (BBB). Here, we sought to build a construct with the capacity to cross this barrier, to behave as a chemical delivery system, and, once inside the central nervous system, to be

A novel dual-stimuli cleavable linker containing adjacent UV light-sensitive o-nitrobenzyl ester and GSH-responsive disulfide bonds was first designed and synthesized to increase the responsivity to external stimuli. The functionalized linker was then uti

Paragraph 0145; 0152-0153, (2021/08/20)
The present invention provides photo-cleavable anionic surfactants, particularly 4-hexylphenylazosulfonate (Azo) and sodium 4-hexylphenylazosulfonate derivatives, which can be rapidly degraded upon UV irradiation, for top-down and bottom-up proteomics. These surfactants can effectively solubilize proteins and peptide fragments with performance comparable to sodium dodecyl sulfate (SDS) and are compatible with mass spectrometry analysis of the solubilized proteins and peptide fragments. Top-down proteomic studies using the present photo-cleavable anionic surfactants has allowed the detection of 100-fold more unique proteoforms as compared to controls and has enabled the solubilization of membrane proteins for comprehensive characterization of protein post-trans-modifications. In addition, the present photo-cleavable anionic surfactants are also suitable for dissolving polypeptides in bottom-up proteomic experiments including extracellular matrix proteomics, and are suitable as a substitute for SDS in gel electrophoresis.

The invention relates to a photo-induced multifunctional cross-linking agent as shown in a general formula (I), wherein the photo-induced multifunctional cross-linking agent is mainly applied to biomacromolecule interaction, such as protein-protein interaction and protein-nucleic acid interaction. According to the invention, the cross-linking agent can be used in biological samples or cells of cell lysis solutions to capture protein-protein interaction or protein-nucleic acid interaction, and can be applied to subsequent protein enrichment and protein cross-linking mass spectrometry; and the photo-induced multifunctional cross-linking agent has important application potential and practical value in interaction research of biomacromolecules.
Multi-stimuli controlled release of a transmembrane chloride ion carrier from a sulfonium-linked procarrier

In recent times, anion transporters have received substantial consideration due to their ability to disrupt the ionic equilibrium across membrane bilayers. While numerous Cl- ion transporters were developed for channelopathies, unfortunately, poor aqueous solubility precluded their bioapplicability. Herein, we demonstrate the development of a multi-stimuli activatable anion transport approach to induce regulated transport of Cl- ions across membranes under specific conditions. The sulfonium-based procarrier was initially inactive, but the transmembrane transport of Cl- ions was activated in the presence of stimuli such as glutathione (GSH), reactive oxygen species (ROS) and light. The release of the hydrophobic anionophore from the aqueous-soluble procarrier under specific conditions leads to the successful transport of Cl- ions. Under physiological conditions, these anion carriers follow an antiport exchange mechanism to transport Cl- ions across lipid bilayers. Such multi-stimuli activatable procarriers have great potential to combat various types of channelopathies, including cancer, cystic fibrosis, kidney stones, myotonia, and others.
