Reaction of NO with hypochlorous acid [PDF]

International Journal of Chemical Kinetics, 1979
AbstractThe reaction between NO(g) at concentrations between 0.1 and 1.0 Torr in 1‐atm N2 and aqueous solutions of NaClO has been studied over the pH range of 6–12 and hypochlorite concentrations between 0.01 and 1.0M. A very rapid and efficient reaction occurs leading to the production of about 30%–40% of the NO as NO2 and with conversions of NO up to

A Fast-Responsive OFF-ON Near-Infrared-II Fluorescent Probe for In Vivo Detection of Hypochlorous Acid in Rheumatoid Arthritis.

Analytical Chemistry, 2021
Rheumatoid arthritis (RA) is a common chronic autoimmune inflammatory disease, and its etiology is closely related to the overproduction of hypochlorous acid (HClO).

Mechanism of cyanocobalamin chlorination by hypochlorous acid

JBIC Journal of Biological Inorganic Chemistry, 2021
Hypochlorous acid (HOCl) is a strong oxidant produced by myeloperoxidase. Previous work suggested that HOCl modifies the corrin ring of cobalamins to yield chlorinated species via mechanisms that are incompletely understood. Herein, we report a mechanistic study on the reaction between cyanocobalamin (CNCbl, vitamin B12) and HOCl.

Ratiometric Detection of Hypochlorous Acid in Brain Tissues of Neuroinflammation and Maternal Immune Activation Models with a Deep-Red/Near-Infrared Emitting Probe.

ACS Sensors, 2021
Reactive oxygen species (ROS) produced by an inflammatory response in the brain are associated with various neurological disorders. To investigate ROS-associated neuroinflammatory diseases, fluorescent probes with practicality are in demand.

Reaction of uracil with hypochlorous acid

Biochemical and Biophysical Research Communications, 1978
Abstract The end products of the reaction of uracil with at least a 10-fold excess of aqueous hypochlorous acid at pH 7–8 were found to be trichloroacetic acid, carbon dioxide and nitrogen trichloride. Little formation of trichloroacetic acid was observed after 24 hours when the ratio of hypochlorous acid to uracil was less than 4:1.

Cephalosporins are scavengers of hypochlorous acid

Biochemical Pharmacology, 1995
Potential scavenging properties of cephalosporins (i.e. cefamandole, cefotaxime and ceftriaxone) towards hypochlorous acid (HOCl) as well as the antibacterial activity of control and HOCl-reacted antibiotics were investigated. We found that these drugs, at therapeutically relevant concentrations, are indeed scavengers of HOCl, with ceftriaxone showing ...

Modification of phosphatidylserine by hypochlorous acid

Chemistry and Physics of Lipids, 2009
The binding of the heme enzyme myeloperoxidase to phosphatidylserine epitopes on the surface of non-vital polymorphonuclear leukocytes and other cells at inflammatory sites favours modifications of this phospholipid by myeloperoxidase products. As detected by MALDI-TOF mass spectrometry hypochlorous acid and the myeloperoxidase-hydrogen peroxide ...
