Metal- and acid-free, TBN-mediated direct CH nitration of arenes

open access: yesJournal of Saudi Chemical Society, 2019
A metal-free, acid-free, direct and eco-friendly nitration methodology has been developed. A tert-butyl nitrite efficiently promotes the direct CH nitration of electron-rich arenes with good to excellent yields and regioselectivities.

KINETICS STUDY ON NITRATION OF METHYL RICINOLEATE [PDF]

open access: yesIndonesian Journal of Chemistry, 2012
Kinetics parameter values of methyl ricinoleate nitration (rate constant, reaction order and the rate of reaction) have been determined. Nitration was carried out with both concentrations of HNO3 and acetic anhydride in excess to the concentration of ...

Protein Tyrosine Nitration in Plant Nitric Oxide Signaling

open access: yesFrontiers in Plant Science, 2022
Nitric oxide (NO), which is ubiquitously present in living organisms, regulates many developmental and stress-activated processes in plants. Regulatory effects exerted by NO lies mostly in its chemical reactivity as a free radical.

A pilot study on nitration/dysfunction of NK1 segment of myogenic stem cell activator HGF

open access: yesBiochemistry and Biophysics Reports, 2022
Protein tyrosine residue (Y) nitration, a post-translational chemical-modification mode, has been associated with changes in protein activity and function; hence the accumulation of specific nitrated proteins in tissues may be used to monitor the onset ...

Nitrate and periplasmic nitrate reductases [PDF]

open access: yesChem. Soc. Rev., 2014
The nitrate anion is a simple, abundant and relatively stable species, yet plays a significant role in global cycling of nitrogen, global climate change, and human health. Although it has been known for quite some time that nitrate is an important species environmentally, recent studies have identified potential medical applications.

RAC1 nitration at Y32 IS involved in the endothelial barrier disruption associated with lipopolysaccharide-mediated acute lung injury

open access: yesRedox Biology, 2021
Acute lung injury (ALI), a devastating illness induced by systemic inflammation e.g., sepsis or local lung inflammation e.g., COVID-19 mediated severe pneumonia, has an unacceptably high mortality and has no effective therapy.

Impact of Protein Nitration on Influenza Virus Infectivity and Immunogenicity

open access: yesMicrobiology Spectrum, 2022
Influenza viruses are deadly respiratory pathogens of special importance due to their long history of global pandemics. During influenza virus infections, the host responds by producing interferons, which activate interferon-stimulated genes (ISGs ...
