ROS-Scavenging Therapeutic Hydrogels for Modulation of the Inflammatory Response.

ACS Applied Materials and Interfaces, 2021
Although reactive oxygen species (ROS) are essential for cellular processes, excessive ROS could be a major cause of various inflammatory diseases because of the oxidation of proteins, DNA, and membrane lipids.

ROS-scavenging hydrogel to promote healing of bacteria infected diabetic wounds.

Biomaterials, 2020
Bacterial infection has been a great threat to dermal wounds, especially to difficult-to-heal diabetic wounds. It is known that reactive oxygen species (ROS) generated by wounds or bacterial infection could further impede wound healing.

Propofol Is a Peroxynitrite Scavenger

Anesthesia & Analgesia, 1997
P eroxynitrite is a potent oxidant formed by the rapid reaction between nitric oxide and superoxide radical (1). The peroxynitrite anion is relatively stable, but it can rapidly protonate to peroxynitrous acid, an unstable species, which decomposes with a half-life of about one second at pH 7.4 (1,2).

Melatonin is a scavenger of peroxynitrite

Life Sciences, 1997
Peroxynitrite is a toxic oxidant formed from the reaction of superoxide and nitric oxide under conditions of inflammation and oxidant stress. Here we demonstrate that the pineal neurohormone melatonin inhibits peroxynitrite-mediated oxidant processes. Melatonin caused a dose-dependent inhibition of the oxidation of dihydrorhodamine 123 to rhodamine in ...

Scavenger and Sentry:

2020
Foragers domesticated dogs before plants and livestock. In the Near East, dogs are present from the Epipaleolithic, living with settled foragers. With the advent of farming in the Neolithic, human activities changed and dogs’ lives surely did as well. Dogs have served many roles in human societies: food, pet, guard, herding aid, and scavenger, to name ...

Characterization and Application of Lignin–Carbohydrate Complexes from Lignocellulosic Materials as Antioxidants for Scavenging In Vitro and In Vivo Reactive Oxygen Species

, 2020
Lignin–carbohydrate complexes (LCCs) have shown antioxidant ability to scavenge the individual free radicals in vitro, while little work has been carried out to show if the LCCs can efficiently scavenge the intracellular and endogenous reactive oxygen ...

Peroxynitrite Scavenging by Flavonoids

Biochemical and Biophysical Research Communications, 1997
The peroxynitrite scavenging activity of a series of structurally related flavonoids was tested. It was found that flavonoids are excellent scavengers of peroxynitrite. Compared to the known peroxynitrite scavenger ebselen, the most active flavonoids proved to be 10 times more effective.

Sustainable Nanosheet Antioxidants for Sepsis Therapy via Scavenging Intracellular Reactive Oxygen and Nitrogen Species.

ACS Nano, 2020
Sepsis is an aberrant systemic inflammatory response mediated by excessive production of reactive oxygen species (ROS) and reactive nitrogen species (RNS).
