Reactive Oxygen Species (ROS)
Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

Acetyl zingerone
0 ImagesAcetyl zingerone is an analog of Zingerone (HY-14621). Acetyl zingerone downregulates the expression of ROS metabolism-related genes, fibroblast senescence-related genes, keratinocyte differentiation-related genes, and IL-17A target genes. Acetyl zingerone inhibits the activities of MMP-1, MMP-3, and MMP-12, as well as the activation of NLRP3 inflammasome, pyroptosis (pyroptosis), ferroptosis (ferroptosis), cartilage destruction, and UVA-induced cyclobutane pyrimidine dimer formation.

Phellodendrine
0 ImagesPhellodendrine is an orally active plant alkaloid. Phellodendrine inhibits the proliferation of KRAS-mutated pancreatic cancer cells by suppressing macropinocytosis and glutamine metabolism, inducing ROS accumulation and mitochondrial apoptosis.

Phellodendrine can alleviate gouty arthritis by inhibiting the IL-6/STAT3 signaling pathway. Phellodendrine suppresses allergic reactions by altering the conformation of MRGPRB3/MRGPRX2 protein, thereby inhibiting the activation of PKC and subsequent downstream MAPK and NF-κB signaling. Phellodendrine inhibits the AKT/NF-κB pathway and down-regulates the expression of COX-2, thereby protecting zebrafish embryos from oxidative stress. Phellodendrine has an anti-major depressive disorder (MDD) effect by down-regulating CHRM1, HTR1A, and the PI3K/Akt signaling pathway.

Quinclorac
0 ImagesQuinclorac is a highly selective quinoline carboxylic acid synthetic auxin herbicide. Quinclorac weakly inhibits HPPD, accompanied by a transient decrease in carotenoids. Quinclorac upregulates ACC synthase (ACS), leading to the co-accumulation of ethylene and cyanide, while increasing the ABA/IAA ratio, which induces ROS burst, membrane lipid peroxidation (MDA) and lethal growth inhibition. Residual Quinclorac in soil can cause abnormal growth of subsequent tobacco crops. In calli of Phaseolus vulgaris, Quinclorac induces oxidative stress (increased MDA and decreased RGR), but cells after stepwise pressurized acclimation acquire a constitutive antioxidant state, which remains stable after de-acclimation and tolerates oxidative damage caused by Quinclorac. Quinclorac can be used in studies related to herbicide action mechanisms, bioremediation of soil residues, and adaptive responses of plant cells to oxidative stress.
