Tiomolibdate diammonium (NSC-286644) is an inhibitor of superoxide dismutase 1 (SOD1) exerting antiangiogenic and antitumor activities. Tiomolibdate diammonium inhibits the activities of cuproenzymes, including SOD1 and COX.

NF-κΒ activator 1 can activate the nf-kappa Β gene activator, EC50 of 0.9 microns. NF-κΒ is widely used in eukaryotic cells as a gene regulating cell proliferation and cell survival. NF-κΒ activator 1 induces superoxide dismutase (SOD) 2 1 mRNA expression.

Morin monohydrate (oxylon pomiferum monohydrate) is a flavonoid extracted from Morus alba plant with anticancer, antioxidant, and anti-inflammatory activities, which reduces T-2 toxin-induced TNF-alpha, COX-2, IL-1β, IL-6, caspase-1, caspase-3, and caspase-11 mRNA. BML-286 is a WNP-containing WNP-containing BML-286, which reduces T-2 toxin-induced TNF-α, COX-2, IL-1β, IL-6, caspase-1, caspase-3, and caspase-11 mRNA expression, and ameliorates T-2 toxin-induced injury by decreasing malondialdehyde (MDA) and increasing superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione peroxidase (GSH-PX).

1. ISOGINKGETIN (4',4'''-Dimethylamentoflavone), a compound derived from the leaves of Ginkgo biloba, to up-regulate adiponectin secretion with potency comparable to that of rosiglitazone, a known modulator of adiponectin production. 2. Isoginkgetin has anti-tumor activity, the mechanistic basis is splicing inhibition , thus, pre-mRNA splicing inhibitors may represent a novel avenue for development of new anti-cancer agents.3. Isoginkgetin can inhibit tumor cell invasion by regulating phosphatidylinositol 3-kinase Akt-dependent matrix metalloproteinase-9 expression. 4. Isoginkgetin (0.3mg kg ip for 3d) can reduce the level of O2·- in plasma and erythroeyte and sometimes increase the activity of SOD in anoxic rats, the action being stronger than aspirin.

1. Pectolinarigenin (Pectolinaringenin) exhibits hepatoprotective activity mainly via SOD antioxidant mechanism. 2. Pectolinarigenin possesses anti-inflammatory activity and that they may inhibit eicosanoid formation in inflammatory lesions.

Tat-Gap 19, a peptide inhibitor of connexin43 (Cx43) hemichannels, is derived from the HIV-1 Tat protein transduction domain fused with a nine-amino acid sequence from Cx43 residues 128-136. This compound, at a concentration of 10 µM, effectively suppresses glutamate-induced ATP release in primary rat hepatocytes, indicating inhibition of Cx43 hemichannel activity. Furthermore, Tat-Gap 19 demonstrates therapeutic potential by significantly reducing infarct volume in a mouse cerebral ischemia-reperfusion injury model following middle cerebral artery occlusion (MCAO) at a dosage of 25 mg/kg. Moreover, its intraperitoneal administration at 1 mg/kg per day ameliorates fibrosis and decreases the area of hepatic stellate cells, the precursors to myofibroblasts, expressing α-smooth muscle actin (α-SMA), in a model of thioacetamide-induced liver damage. Additionally, it enhances superoxide dismutase (SOD) activity in hepatic cells from the treated mice, indicating its antioxidative benefits.

Pheophytin a, a chlorophyll isolated from S. vermiculata extracts, demonstrates antioxidant activity with IC50 values of 200.5 and 137.7 μg mL for SOD and NO, respectively. It also exhibits reducing power (IC50 = 4.2 μg mL) and a cytotoxic effect on the MCF-7 cell line (IC50 = 35.9 μg mL) [1].

1-Methylcyclopropene (1-MCP) is an ethylene inhibitor that irreversibly binds to ethylene receptors, blocking the ethylene binding sites. This compound enhances the activities of SOD and POD enzymes. Additionally, 1-Methylcyclopropene delays the softening of soft jujube kiwi fruit, thereby extending its shelf life and storage duration. It achieves this by reducing the activity of cell wall-modifying enzymes, which slows down the degradation of cell wall components (including pectin, cellulose, and hemicellulose).

Trilobatin (P-Phlorizin) has anti-oxidant effect, can increase superoxide dismutase (SOD) activity.Trilobatin has anti-inflammatory effect, it potentially inhibits the lipopolysaccharide (LPS)-induced inflammatory response by suppressing the NF-κB signaling pathway.Trilobatin shows a strong inhibitory activity against α-glucosidase and a moderate inhibitory activity against α-amylase for management of postprandial hyperglycemia with less side effect.

Superoxide dismutase (SOD), an enzyme that alternatively catalyzes the disproportionate decomposition of superoxide anion radicals (O2-) to O2 and H2O2, is an important antioxidant defense mechanism that effectively reduces pro-inflammatory cytokines and inhibits neutrophil infiltration into sites of tissue damage.

Antioxidant agent-3 (Compound 14q), a potent antioxidant, exhibits strong scavenging activity against DPPH radicals and ABTS+ radicals with IC50 values of 26.58 μM and 30.31 μM, respectively. Additionally, it enhances levels of reactive oxygen species (ROS), superoxide dismutase (SOD), and glutathione (GSH), while diminishing lactate dehydrogenase (LDH) in H2O2-treated HepG2 cells [1].

Mn(III)TMPyP is a manganese-porphyrin which acts as a superoxide dismutase (SOD) mimetic and peroxynitrite decomposition catalyst. SOD mimetics described to date are unstable and are capable of catalyzing undesired side-reactions in addition to the dismutation of the superoxide radical (O2-). Mn(III)TMPyP is an SOD mimetic with increased stability to pH and hydrogen peroxide. The rate constant for superoxide dismutation and peroxynitrite decomposition are 3.9 x 107 M-1s-1 and ~2 x 106 M-1s-1, respectively. Mn(III)TMPyP protected and enhanced the growth of SOD E. coli with a doubling time of 60 minutes (as compared to 240 minutes of the control) at 25 µM.

NF-κΒ Activator 2 is a potent, orally active compound that efficiently activates NF-κB with an EC50 value of 1.58 μM. By enhancing NF-κB expression and activation, it induces SOD 2 synthesis, rendering it useful for amyotrophic lateral sclerosis (ALS) research [1].
