Carteolol hydrochloride (Abbott-43326) is a synthetic quinolinone derivative, antihypertensive Carteolol Hydrochloride is a nonselective beta-adrenoceptor blocking agent for beta-1 and beta-2 receptors with no membrane-stabilizing activity but moderate intrinsic sympathomimetic effects. It is used for the treatment of hypertension and certain arrhythmias and as an anti-angina and antiglaucoma agent.

11-oxo-mogroside V (11-oxo Mogroside V) is a sweet tasting cucurbitane glycoside derivative of mogroside V. It has antioxidant effects against both O2- and OH- and prevents OH-induced DNA damage.

3,4-Dimethoxybenzyl alcohol is a secondary metabolite of lignin-degrading fungi and is commonly used as a non-phenolic substrate to measure ligninolytic activity.Veratryl alcohol protects lignin peroxidase (LiP) from inactivation by H2O2 and prevents accumulation of LiP III compounds[3].

Catalase is an essential enzyme in the metabolism of H2O2 and reactive oxygen species (ROS), making it useful for tumor research. Solutions of catalse should not be frozen. Frozen solution will result in a 50-70% loss of activity. Catalase is recommended to be prepared freshly before use.

2,5-dimethoxycyclohexa-2,5-diene-1,4-dio (Thermophillin) is a natural product. The redox cycle of 2,5-dimethoxybenzoquinone is a source of reducing equivalent for the regeneration of Fe2+ and H2O2 in brown rot fungal decay of wood.

BRD3067 FA is a natural product and a SIRT2 inhibitor with neuroprotective properties, capable of preventing H₂O₂-induced neuronal injury. Used in Alzheimer's disease-related research, this compound exhibits anti-neuroinflammatory and cognitive function-improving activities.

MAO-B-IN-2 is a selective and competitive inhibitor of MAO-B and BChE with IC50 values of 0.51 μM and 7.00 μM, respectively. It attenuates H2O2-induced cellular damage due to its strong ROS scavenging properties.

Methyl 3-hydroxy-4,5-dimethoxybenzoate (3,4-Dimethoxy-5-hydroxybenzoic acid methyl ester) is a gallic acid derivative from Pinus sylvestris exhibiting antibacterial activity and antioxidant properties in the presence of H2O2.

Ezetimibe ketone (EZM-K) is a metabolite of Ezetimibe with antioxidant activity, alleviating H2O2-induced apoptosis and reactive oxygen species (ROS) in NRK-52E cells, upregulating Nrf2 and HO-1 levels.

Huangjiangsu A has hepatoprotective potential against H2O2-induced cytotoxicity and ROS generation and could be promising as potential therapeutic agents for liver diseases. Huangjiangsu A is isolated from D. villosa.

AChE/BChE-IN-21 is an antagonist of the histamine H3 receptor, a calcium channel blocker, and an acetylcholinesterase inhibitor. It exhibits neuroprotective activities against H2O2 and Aβ1-40, and can restore cognitive functions in AD mice.

FO-4-15 is an activator of mGluR1/CaMKIIα. It exhibits protective effects against H2O2 in human neuroblastoma (SH-SY5Y) cells. In mice with Alzheimer's disease, FO-4-15 enhances cognitive function by activating the mGluR1/CaMKIIα pathway, reducing Aβ accumulation, Tau hyperphosphorylation, and synaptic damage.

Res-Glu3, a derivative of Resveratrol, exhibits antioxidant activities in a rat ischemia-reperfusion model and reduces ROS accumulation. It also provides neuroprotection against H2O2-induced cellular damage in PC12 cells.

9(10)-Nitrooleate, a mixture of endogenous lipid signaling molecules composed of 9-nitrooleic acid and 10-nitrooleic acid, is synthesized through nitration of oleic acid in the presence of peroxynitrite, nitrous acid, and myeloperoxidase with hydrogen peroxide (H2O2) and nitrite as auxiliary reagents.

Dopaminechrome (DACHR) is an oxidation product of dopamine that promotes the generation of H2O2 at mitochondrial complex I in the brain in a concentration- and respiration-dependent manner. It possesses neurotoxic properties and can be utilized in Parkinson's disease research.
