1. ((o-Carboxyphenyl)thio)ethylmercury, Sodium Salt
[An organomercurial compound and derivative of thiosalicyclic acid with antibacterial and antifungal properties. Although the mechanism of action has not been fully elucidated, thimerosal inhibits sulfhydryl-containing active site of various enzymes and binds to sulfhydryl compounds, such as glutathione, cysteine, and SH groups of proteins. In addition, thimerosal activates the InsP3 calcium channel on endoplasmic reticular membrane, thereby triggering the release of calcium from intracellular stores resulting in a calcium-induced calcium-influx of extracellular calcium. Consequently, thimerosal may induce or inhibit cellular functions dependent on calcium signaling. ( NCI )] (UMLS (NCI) C0039867) =Organic Chemical; Pharmacologic Substance ;

3. (o-Bromobenzyl)ethyldimethylammonium p-Toluenesulfonate
[The tosylate salt form of bretylium, a quaternary ammonium salt and non-selective adrenergic neuronal blocking agent with anti-arrhythmic properties. Bretylium tosylate is selectively taken up into peripheral nerve terminals and initially causes a release of norepinephrine from sympathetic nerve endings, thereby causing a sympathomimetic effect. This is followed by a prolonged anti-adrenergic action which prevents further discharge of neurotransmitter from sympathetic nerve endings. Its myocardial effects include a prolongation of action potential as well as refractory period. This drug is used to treat and suppress ventricular arrhythmias, particularly ventricular fibrillation and ventricular tachycardia.

[A synthetic, colorless liquid or white crystalline solid that is readily soluble in water and many organic solvents such as ketones, esters and aromatic hydrocarbons. 1,3-propanesultone is used as a chemical intermediate in the production of detergents, dyes, lathering agents, bacteriostats, fungicides, insecticides, cation-exchange resins, corrosion inhibitors and vulcanization accelerators. When heated to decomposition, it emits toxic fumes of sulfur oxides. Humans are potentially exposed to residues of 1,3-propane sultone when using products manufactured from this compound. The primary routes of potential human exposure to 1,3-propane sultone are ingestion and inhalation. Contact with this chemical can cause mild irritation of the eyes and skin.

[A synthetic analog of lysophosphatidylcholine, an ether lipid, possessing anti-leishmanial and antineoplastic activity. The mechanism of action for edelfosine has not been fully elucidated. Targeting cellular membranes, edelfosine modulates membrane permeability, membrane lipid composition, and phospholipid metabolism. Edelfosine also inhibits the phosphatidylinositol 3 kinase (PI3K)-AKT/PKB survival pathway, possibly activating the pro-apoptotic stress-activated protein kinase (SAPK/JNK) pathways, thereby inducing apoptosis. In addition, this agent inhibits protein kinase C, intracellular activation of the Fas/CD95 receptor, and intracellular acidification. Anti-leishmanial activity may be due to inhibition of a glycosomal alkyl-specific-acylCoA acyltransferase. (NCI) ( NCI )] (UMLS (NCI) C0044549) =Lipid; Pharmacologic Substance ;

40. 8-Oxoguanine DNA Glycosylase
[The protein 8-Oxoguanine DNA Glycosylase, encoded by the OGG1 gene, is an enzyme in base excision repair. OGG1 incises DNA at 8-oxoguanine residues and excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-n-methylformamidopyrimidine (FAPY) from damaged DNA. OGG1 also has activities of beta-lyase that nicks DNA 3-prime to the lesion and endonuclease that cleaves DNA near apurinic or apyrimidinic sites to products with 5-prime-phosphate. Alternative splicing of the C-terminal region of the OGG1 gene classifies splice variants into two major groups, type 1 and type 2, depending on the last exon of the sequence. Type 1 variants end with exon 7 and type 2 end with exon 8. All variants share the N-terminal region in common (1a/alpha, 1b, 1c, 2a/beta, 2b, 2c, 2d and 2e) and 1a is the prevalent form. OGG1 is ubiquitous and located in nucleus (isoform 1a) and mitochondria (isoform 2a). Defects in OGG1 are associated with tumor formation. ( NCI )] (UMLS (NCI) C1363852) N-Glycosylase/DNA Lyase;
