We previously demonstrated that 1-ethyl-2-benzimidazolone (1-EBIO) directly activates basolateral membrane calcium-activated K(+) channels (K(Ca)), thereby stimulating Cl(-) secretion across several epithelia. In our pursuit to identify potent modulators of Cl(-) secretion that may be useful to overcome the Cl(-) secretory defect in cystic fibrosis (CF), we have identified chlorzoxazone [5-chlo...
BACKGROUND The identification of strategies to improve mutant CFTR function remains a key priority in the development of new treatments for cystic fibrosis (CF). Previous studies demonstrated that the K⁺ channel opener 1-ethyl-2-benzimidazolone (1-EBIO) potentiates CFTR-mediated Cl⁻ secretion in cultured cells and mouse colon. However, the effects of 1-EBIO on wild-type and mutant CFTR function...
The adsorption behavior of Benzimidazol-2-one (Bz), 5-Methylbenzimidazol-2-one(CH3Bz) and 5-Chlorobenzimidazol-2-one (ClBz) as inhibitors for mild steel corrosion in HCl 1M have been studied computationally using density functional theory (DFT) calculations with the hybrid B3LYP functional. The calculations were focused on the protonated forms of the molecules under study, seeing tha...
p-Nitrophenyl N-(2-mercaptophenyl)-N-methylcarbamate cyclizes rapidly at 25' to N-methylbenzothiazolone with release of p-nitrophenol. The pH-rate constant profile is sigmoidal with pK,,, = 8.7. The effective molarity of the neighboring sulfhydryl group is 1.4 X los M in comparison with bimolecular attack of thiols on p-nitrophenyl N-methyl-Nphenylcarbamate. The pH-rate constant profile for cyc...
A robust binary hydrogen-bonded supramolecular organic framework (SOF-7) has been synthesized by solvothermal reaction of 1,4-bis-(4-(3,5-dicyano2,6-dipyridyl)dihydropyridyl)benzene (1) and 5,5′-bis(azanediyl)-oxalyl-diisophthalic acid (2). Single crystal Xray diffraction analysis shows that SOF-7 comprises 2 and 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)pyridyl)benzene (3); the latter formed in si...
