APPLICATION OF PHOTOELECTRON SPECTROSCOPY TO BIOLOGICALLY ACTIVE MOLECULES AND THEIR CONSTITUENT PARTS. VII. N-CYANOAZOMETHINES

A series of N-cyanoazomethines 1-12 has been synthesized, and their electronic properties studied by He(I) photoelectron (PE) spectroscopy using the composite molecule approach.This allows partial assignment of the ionization energies in the PE spectrum of cimetidine 16, a known H2-receptor antagonist.Determination of differential UV spectra of the model compounds 7 and 13 revealed that no intramolecular charge transfer (CT) interaction exists between the two “ends” of the cimetidine molecule, i.e. between the ?-electron rich imidazole ring and the relatively ?-electron deficient cyanoguanidine moiety.

Two small molecules restore stability to a subpopulation of the cystic fibrosis transmembrane conductance regulator with the predominant disease-causing mutation

Cystic fibrosis (CF) is caused by mutations that disrupt the plasma membrane expression, stability, and function of the cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel. Two small molecules, the CFTR corrector lumacaftor and the potentiator ivacaftor, are now used clinically to treat CF, although some studies suggest that they have counteracting effects on CFTR stability. Here, we investigated the impact of these compounds on the instability of F508del-CFTR, the most common CF mutation. To study individual CFTR Cl- channels, we performed single-channel recording, whereas to assess entire CFTR populations, we used purified CFTR proteins and macroscopicCFTRCl-currents. At 37 C, low temperature-rescued F508del-CFTR more rapidly lost function in cell-free membrane patches and showed altered channel gating and current flow through open channels. Compared with purified wildtype CFTR, the full-length F508del-CFTR was about 10 C less thermostable. Lumacaftor partially stabilized purified fulllength F508del-CFTR and slightly delayed deactivation of individual F508del-CFTR Cl- channels. By contrast, ivacaftor further destabilized full-length F508del-CFTR and accelerated channel deactivation. Chronic (prolonged) co-incubation of F508del-CFTR-expressing cells with lumacaftor and ivacaftor deactivated macroscopic F508del-CFTR Cl- currents. However, at the single-channel level, chronic co-incubation greatly increased F508del-CFTR channel activity and temporal stability in most, but not all, cell-free membrane patches. We conclude that chronic lumacaftor and ivacaftor co-treatment restores stability in a small subpopulation of F508del-CFTR Cl- channels but that the majority remain destabilized. A fuller understanding of these effects and the characterization of the small F508del-CFTR subpopulation might be crucial for CF therapy development.

Development of a novel sulfonate ester-based prodrug strategy

A self-immolative gamma-aminopropylsulfonate linker was investigated for use in the development of prodrugs that are reactive to various chemical or biological stimuli. To demonstrate their utility, a leucine-conjugated prodrug of 5-chloroquinolin-8-ol (5-Cl-8-HQ), which is a potent inhibitor against aminopeptidase from Aeromonas proteolytica (AAP), was synthesized. The sulfonate prodrug was considerably stable under physiological conditions, with only enzyme-mediated hydrolysis of leucine triggering the subsequent intramolecular cyclization to simultaneously release 5-Cl-8-HQ and form gamma-sultam. It was also confirmed that this gamma-aminopropylsulfonate linker was applicable for prodrugs of not only 8-HQ derivatives but also other drugs bearing a phenolic hydroxy group.
