radical generation

3-(3-Methoxyphenyl)acrylic acid can inhibit free radical generation, has antioxidant potential, and can be used in biochemical experiments and drug synthesis.

AD 0261 is a radical scavenger. It has a strong inhibitory action on the generation of lipid peroxides and superoxide anions.

N-Stearoyltyrosine (N-(1-Oxooctadecyl)-L-tyrosine) is an analog of Anandamide. It exhibits neuroprotective effects by safeguarding the CA1 region of the hippocampus in a gerbil ischemia-reperfusion model. Additionally, N-Stearoyltyrosine inhibits free radical generation, enhances antioxidant capacity, and reduces IR-induced apoptosis (cell apoptosis).

PI3K-IN-59 (Compound 3d) is a PI3K inhibitor with an IC50 value of 17.44 μM. It demonstrates significant antiproliferative activity, showing potent inhibition against breast cancer 4T1 cells (IC50: 3.70 μM), colon cancer CT26 cells (IC50: 1.98 μM), and human breast cancer cells (IC50: 19.72 μM). The compound operates through a dual antitumor mechanism by inhibiting PI3Kα enzymatic activity and inducing hydroxyl radical (•OH) generation via the Fenton reaction. PI3K-IN-59 shows promising efficacy against 4T1 tumors, making it suitable for synergistic targeting studies in breast and colon cancer.

AAPH is a water-soluble azo compound which is used extensively as a free radical generator, often in the study of lipid peroxidation and the characterization of antioxidants.[1],[2],[3],[4] Decomposition of AAPH produces molecular nitrogen and 2 carbon radicals. The carbon radicals may combine to produce stable products or react with molecular oxygen to give peroxyl radicals. The half-life of AAPH is about 175 hours (37°C at neutral pH), making the rate of free radical generation essentially constant during the first several hours in solution.[5] While AAPH may be used effectively for lipid peroxidation in aqueous dispersions of fatty acids, other radical generators may be better suited for peroxidation studies in lipid micelles or membranes.[6],[7]

Lazabemide (Ro 19-6327) is a selective and reversible monoamine oxidase B (MAO-B) inhibitor with IC50 values of 0.03 μM for MAO-B and >100 μM for MAO-A.

Lazabemide hydrochloride (N-(2-Aminoethyl)-5-chlor-2-pyridincarbox) is a reversible and selective mao-b inhibitor(Ki:7.9nM).

I2959, widely known as Irgacure 2959, is a photoinitiator extensively used for ultraviolet light-induced photocrosslinking of hydrogels in biomedical applications and is particularly utilized in combination with carboxymethylcellulose (CMA) hydrogels as a bioink for bio 3D printing applications; furthermore, I2959 is recognized for its high radical generation efficiency under UV exposure but also exhibits concentration-dependent cytotoxicity to rapidly dividing cell lines.
