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

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.

To improve the therapeutic efficacy of anticancer drugs and reduce its toxic side effects, we synthesized a series of amphiphilic o-nitrobenzyl molecules 4-(4-N,N,N,N-dicarboxymethyl-diethylenetriamino)acetoxymethyl-3-nitro-N,N-dialk-ylbenzamide (N,N-NB-DTPA) with good photolysis property and acid sensitivity. Simultaneously, N, N-NB-DTPA liposomes composed of the o-nitrobenzyl molecules have good biocompatibility, low hemolysis rate and cytotoxicity, and the drug encapsulation efficiency of the liposomes exceeds 70%. N, N-NB-DTPA-DOX liposomes possess good stability and can keep uniform distribution in PBS solution for 10 days. The drug release rate of these drug-loaded liposomes reaches to the maximums under pH 5.0 and 30 min UV irradiation, revealing pH/UV dual-responsiveness of these drug-loaded liposomes. The low pH makes DOX separate from these drug-loaded liposomes, and the UV irradiation leads to o-nitrobenzyl ester bond cleave, which contribute to accelerate the release of drug from drug-loaded liposomes. Furthermore, N, N-NB-DTPA-DOX liposomes after UV irradiation have better therapeutic effect than single DOX·HCl, which may result from the production of nitrosobenzaldehyde derivatives after UV irradiation.

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.
