An organic phosphorothioate anion that is the conjugate base of O,O-diethyl hydrogen thiophosphate, resulting from the deprotonation of the thiophosphate group. Major species at pH 7.3.
A hydrochloride obtained by combining 4,4'-carbonimidoylbis(N,N-dimethylaniline) with one molar equivalent of hydrogen chloride. A fluorescent stain for demonstrating acid fast organisms in a method similar to the Ziehl Neelsen. It also can be used to make a fluorescent Schiff reagent.
A xanthene dye that is fluorescein in which the hydrogens at positions 2',4',5' and 7' are replaced by bromo groups, and the hydrogens at positions 4,5,6 and 7 are replaced by chloro groups. It is a red synthetic pigment which is widely used in colored cosmetics (e.g. lipsticks and blushers).
A substituted aniline that is aniline in which the hydrogen ortho to the amino group has been replaced by a methoxy group. It is used as a chemical intermediate in the synthesis of azo pigments and dyes.
A cyclodepsipeptide isolated from Jaspis splendens. A derivative of jaspamide, it has been shown to exhibit cytotoxic and microfilament disruption activity.
A piperidine alkaloid that consists of 5,7-dihydroxyflavone attached to a 1-methylpiperindin-2-yl moiety at position 8. It is a flavonoid alkaloid isolated from Buchenavia capitata, and has been shown to exhibit anti-HIV activity.
The term used to refer to the carbohydrate portion of O-glycoproteins when attached to the hydroxyl oxygen of serine, threonine, hydroxylysine or hydroxyproline side-chains.
A cephalosporin compound having (R)-O-formylmandelamido and N-methylthiotetrazole side groups. It is used (as the sodium salt) as a progrug for cefamandole.
A repetitive glycan polysaccharide contained within a lipopolysaccharide (LPS). The O-antigen is attached to the core oligosaccharide, and comprises the outermost domain of the LPS molecule.
The ethanolamine mono-ester of phosphoric acid, and a metabolite of phospholipid metabolism. This phosphomonoester shows strong structural similarity to the inhibitory neurotransmitter GABA, and is decreased in post-mortem Alzheimer's disease brain.
An imine formed formally from a quinodimethane by replacement of one or more atoms of the methylene groups, which are situated ortho to each other, by =NH or =NR.
A glycoprotein where the carbohydrate portion is linked to the protein component via a glycosidic bond to a hydroxyl oxygen from serine, threonine, hydroxylysine or hydroxyproline side-chains.
An N-acylpiperidine obtained by formal condensation of the carboxy group of 5-[(3-methoxyphenoxy)methyl]-1,2-oxazole-3-carboxylic acid with the secondary amino group of 4-(pyridin-4-yl)piperidine.
A tertiary amino compound that is N,N-dimethylethanamine substituted at position 1 by a 1-hydroxycyclohexyl and 4-hydroxyphenyl group. It is a metabolite of the drug venlafaxine.
[Agren & Andersson 2012] Accumulation of litter and particular decomposed plant parts on top of the mineral soil. Often sub-divided into litter (S, L and F) and humus (H) horizons. This horizon consists mostly of organic matter. In forest soils, this horizon is often called forest floor
