Chloramphenicol mediates superoxide production in Photosystem II and enhances its photodamage in isolated membrane particles

open access: yesFrontiers in Plant Science, 2016
Chloramphenicol is an inhibitor of protein synthesis, which is frequently used to decouple photodamage and protein synthesis dependent repair of Photosystem II during the process of photoinhibition.

Impact of Exposure to Pyraclostrobin and to a Pyraclostrobin/Boscalid Mixture on the Mitochondrial Function of Human Hepatocytes

open access: yesMolecules, 2023
Fungicides are widely used in agriculture for crop protection. Succinate dehydrogenase inhibitors (SDHIs) and strobilurins inhibit mitochondria electron transport chain (ETC) in fungi, by blocking complex II and complex III, respectively.

Differential effects of superoxide dismutase and superoxide dismutase/catalase mimetics on human breast cancer cells

open access: yes, 2015
Reactive oxygen species (ROS) such as superoxide and hydrogen peroxide (H2O2) have been implicated in development and progression of breast cancer. In the present study, we have evaluated the effects of the superoxide dismutase (SOD) mimetic MnTmPyP and ...

Polymeric membranes with selective permeability : shielding of an antioxidant enzyme [PDF]

open access: yes, 2008
In this work we designed an antioxidant nanoreactor based on the encapsulation of CuZnSOD in amphiphilic copolymer nanovesicles. The nanovesicles are formed by self-assembly of amphiphilic copolymer poly-(2-methyloxazoline)-poly- (dimethylsiloxane ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

open access: yesAdvanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Cytochrome c and superoxide [PDF]

open access: yesJBIC Journal of Biological Inorganic Chemistry, 2013
Wegerich et al. (J. Biol. Inorg. Chem. 18:429-440, 2013), working with singly modified human cytochromes c, claim to have found a new mechanism for the reduction of iron(III) cytochrome c by superoxide. I show that electron transfer by way of the solvent-accessible haem edge - a mechanism not considered by Wegerich et al.

Pergolide can induce soluble Superoxide dismutase in rat striata

open access: yes, 1992
Pergolide, a dopamine receptor agonist, given daily i.p. for three weeks at 0.04mg/kg and 0.4mg/kg, significantly induced soluble (Cu-Zn) superoxide dismutase in the rat striatum, while having no effect on the mitochondrial (Mn) form of the enzyme.

An Engineered Biomimetic Nanoreactor With Cascade Functions for Targeted and Combinatorial Therapy of Ischemic Stroke

open access: yesAdvanced Healthcare Materials, EarlyView.
Preparation of RVG‐modified erythrocyte membrane‐coated HMPB nanocarriers loaded with L‐arginine and NBP (RM@HPAN) and its neuroprotective mechanism. After intravenous injection, RM@HPAN achieves prolonged circulation, RVG‐29‐mediated BBB penetration, and ischemic accumulation.
