Queuine is a selective substrate for tRNA guanine transglycosylase (TGT) and can be incorporated into eukaryotic tRNA. Queuine promotes tRNA modification, affecting mitochondrial function and Warburg metabolic phenotype. If Queuine is deficient, aerobic glycolysis can be enhanced, oxidative phosphorylation can be inhibited, and Warburg metabolism can be promoted, accompanied by increased ammonia and lactate production and increased lactate dehydrogenase activity. Queuine can be used for autoimmune diseases (such as experimental models of multiple sclerosis) and cancer metabolic regulation, and its deficiency is associated with low tRNA modification in tumor cells .

8-Bromo-2'-deoxyguanosine is an inflammation-related DNA halogenated adduct and an early biomarker of inflammation-induced oxidative tissue damage. The formation of 8-Bromo-2'-deoxyguanosine precedes that of oxidative and nitrative products, and it can be generated via the MPO-H2O2-Cl --Br - system. 8-Bromo-2'-deoxyguanosine serves as the immunogen for preparing the monoclonal antibody mAb8B3, which can be used to detect early DNA modifications in preclinical models; its urinary level also increases significantly in inflammatory disease models. 8-Bromo-2'-deoxyguanosine can also be produced in the dermis of UV-B irradiated mice, and the extract of Coprinus comatus significantly reduces its level. 8-Bromo-2'-deoxyguanosine finds applications in studies related to inflammatory diseases, diabetes, hepatocellular carcinoma, and UV-B induced skin inflammation .

1,7-Dimethyluric acid is an N-methylated uric acid and purine derivative, as well as a caffeine metabolite. When 1,7-Dimethyluric acid is acted upon by peroxidase in the presence of H2O2, it follows the same oxidation pathway to generate a UV-absorbing intermediate, which decays via first-order kinetics. 1,7-Dimethyluric acid can adsorb onto pyrolytic graphite electrodes, but not onto glassy carbon electrodes or platinum electrodes. The N-methylation modification of its pyrimidine ring prevents ring contraction of the diol intermediate, and no NMR evidence of O-alkylation is observed during propylation under the test conditions .

Nerve Growth Factor 2.5S,murine submaxillary gland is a neurotrophic polypeptide and protein growth factor isolated from murine submaxillary glands. Nerve Growth Factor 2.5S,murine submaxillary gland increases the survival rate, phagocytic capacity and superoxide anion production level of mouse cells. Nerve Growth Factor 2.5S,murine submaxillary gland acts through cell membrane surface receptors to mediate the differentiation and maintenance of adrenergic neurons in the sympathetic nervous system. Nerve Growth Factor 2.5S,murine submaxillary gland loses its activity and undergoes dimer dissociation due to oxidation; it remains active after modification of specific tryptophan residues, while its tyrosine residues are not essential for activity. Nerve Growth Factor 2.5S,murine submaxillary gland may play a role in the inflammatory process .

2,3-Dimethyl-2,3-diphenylbutane is a minor product formed during the thermal decomposition of dicumyl peroxide (DCP) in cumene, generated through radical coupling reactions. As an initiator capable of producing free radicals, 2,3-dimethyl-2,3-diphenylbutane promotes cross-linking or decomposition processes via initiating free radical reactions in fields such as polymer polymerization (e.g., modification of polyphenylene oxide processing), organic synthesis (e.g., DCP decomposition reactions), and coal processing (e.g., oxidation stabilization of coal tar pitch), thereby enhancing material properties or reaction efficiency .

Synonyms: 8-Oxo-Deoxyguanosine triphosphate
8-Oxo-dGTP (8-Oxo-Deoxyguanosine triphosphate) is an oxidized guanine nucleotide formed by ROS-mediated oxidative modification of dGTP, and it also serves as a key substrate for 8-oxo-dGTP pyrophosphohydrolases (such as hMTH1 and E. coli MutT). 8-Oxo-dGTP acts as a DNA mutagen, inserts into nascent DNA and pairs with adenine and cytosine, inducing A:T to C:G transversion mutations. Furthermore, 8-Oxo-dGTP causes oxidative DNA base modification, strand breakage and S-phase arrest, and ultimately triggers AIF-mediated apoptosis and promotes spontaneous carcinogenesis in mth1-deficient mice. Accumulation of 8-Oxo-dGTP in cells induces genomic instability, but it exhibits a tumor-suppressive effect that reduces tumor incidence in mouse models instead. 8-Oxo-dGTP is widely used in studies related to spontaneous carcinogenesis, Parkinson's disease, Alzheimer's disease, heart failure and tumor mechanisms .

Humantenine is a highly toxic indole alkaloid from Gelsemium elegans (Gardn. & Champ.) Benth. that binds to RNA m6A modification regulatory proteins (ALKBH5, METTL). Humantenine stably binds via hydrogen bonding and hydrophobic interactions and disrupts the m6A methylation level of target genes, thereby impairing the expression of intestinal epithelial cell tight junction and cytoskeleton-related genes, causing intestinal barrier dysfunction and significant intestinal cytotoxicity. The intraperitoneal injection LD50 values of Humantenine are <1 mg/kg in mice, 1.2 mg/kg in male rats and 1.5 mg/kg in female rats, respectively. Species differences exist in the metabolism of Humantenine in human, porcine, goat and rat liver microsomes, and demethylation, dehydrogenation and oxidation occur in liver microsomes .
