lipid peroxidation inhibitor 1

Lipid peroxidation inhibitor 1 is an inhibitor of lipid peroxidation (IC50: 0.07 μM).

KKII5 is a potent inhibitor of the lipoxygenase LOX-1 with an IC50 of 19 μM.KKII5 inhibits lipid peroxidation and enhances the ability of the active centers of some compounds to receive electrons.

Carvedilol phosphate hemihydrate (BM 14190 phosphate hemihydrate) is the phosphate salt form of carvedilol, a racemic mixture and adrenergic blocking agent with antihypertensive activity and no intrinsic sympathomimetic activity.

Carvedilol (SKF 105517) Phosphate is the phosphate salt form of carvedilol, a racemic mixture and adrenergic blocking agent with antihypertensive activity and devoid of intrinsic sympathomimetic activity. The S enantiomer of carvedilol nonselectively binds to and blocks beta-adrenergic receptors, thereby exerting negative inotropic and chronotropic effects, and leading to a reduction in cardiac output. In addition, both enantiomers of carvedilol bind to and block alpha 1-adrenergic receptors, thereby causing vasodilation and reducing peripheral vascular resistance.

NYY-6a is a ferroptosis (Ferroptosis) inhibitor, demonstrating significant suppression of RSL3-induced ferroptosis in 786-O and HT-1080 cells, with EC50 values of 52 nM and 50 nM, respectively. As a radical-trapping antioxidant (RTA), NYY-6a effectively reduces lipid peroxidation, comparable to ferrostatin-1 and liproxstatin-1, making it useful for research into ferroptosis-related pathologies.

Erastin2 is a ferroptosis inducer and inhibitor of the system xc- cystine glutamate transporter.[1][2] It inhibits glutamate release in CCF-STTG1 cells (IC50 = 0.0035 µM) and induces cell death in HAP1 cells at 5 µM, an effect blocked by ferrostatin-1 or deferoxamine.[1][2] Erastin2 also induces ferroptotic cell death in HT-1080 cells (EC50 = 0.15 µM), an effect blocked by β-mercaptoethanol (EC50 > 20 µM).[3] Additionally, it increases lipid peroxidation in HT-1080 cells at 1 µM.

9c(i472) is an inhibitor of 15-lipoxygenase-1 (15-LO-1; IC50 = 0.19 μM).1 It decreases LPS- and IFN-γ-induced NF- B activity in RAW-Blue cells when used at concentrations of 0.2, 1, and 5 μM. 9c(i472) reduces LPS- and IFN-γ-induced increases in Nos2 expression and lipid peroxidation in RAW 264.7 cells when used at a concentration of 5 μM.

AMK is an active metabolite of the neurohormone melatonin .1,2,3,4It is formed from melatoninviathe metabolic intermediate AFMK that is then deformylated by catalase or formamidase.5,6AMK scavenges singlet oxygenin vitrowhen used at a concentration of 200 μM.1It inhibits the epinephrine- and arachidonic acid-induced production of prostaglandin E2and PGD2in ovine seminal vesicle microsomes in a concentration- and time-dependent manner, as well as LPS-induced increases in COX-2 levels in RAW 264.7 macrophages when used at a concentration of 500 μM.2,3AMK (20 mg kg) decreases MPTP-induced increases in lipid peroxidation in the cytosol and mitochondria from substantia nigra and striatum in a mouse model of MPTP-induced Parkinson's disease.4 1.Schaefer, M., and Hardeland, R.The melatonin metabolite N1-acetyl-5-methoxykynuramine is a potent singlet oxygen scavengerJ.

DKI5 ((E)-N'-benzylidenehydrazinecarbothiohydrazide) is a LOX-1 inhibitor with an IC50 value of 22.5 μM.DKI5 may have anti-inflammatory and antioxidant activities and has shown anti-lipid peroxidation activity in in vitro bioassays.

6(5H)-Phenanthridinone is an inhibitor of poly(ADP-ribose) polymerase 1 (PARP1) and PARP2. It decreases radiation-induced PARP activity and proliferation of RDM4 murine lymphoma cells. 6(5H)-Phenanthridinone reduces NF-κB-induced transcription of the genes encoding TNF-α, IL-2, and IFN-γ in rat lymphocytes. In vivo, 6(5H)-phenanthridinone reduces spinal cord expression of inducible nitric oxide synthase (iNOS), IL-1β, TNF-α, IL-2, and IFN-γ and reduces disease score in a rat model of experimental autoimmune encephalomyelitis (EAE). It also decreases serum levels of lactate dehydrogenase as well as hepatic lipid peroxidation, oxidative DNA damage, and PARP levels.

Ferroptosis-IN-3 (Compound 25), a ferroptosis inhibitor, demonstrates potent activity by inhibiting RSL3-induced ferroptosis in HT-1080 cells (EC50: 8.6 nM). It exhibits radical scavenging abilities against DPPH and ABTS (EC50: 3.94 and 6.3 μM, respectively), and effectively reduces lipid peroxidation [1].

viFSP1, a species-independent FSP1 inhibitor, effectively induces ferroptosis in FSP1-dependent cells by targeting the highly conserved NAD(P)H binding pocket of FSP1, directly inhibiting its activity. This action results in lipid peroxidation and exhibits anticancer activity [1].

SelB-1 acts as a dual inhibitor of Topoisomerase I II (TopoisomeraseI II), exhibiting anticancer activity suitable for research on prostate and colon cancers. Additionally, SelB-1 can induce the expression of autophagy (autophagy) genes and lipid peroxidation while reducing GSH levels.
