| decamethonium bromide | Decamethylene-1,10-bis-trimethylammonium dibromide;a synthetic nondepolarising neuromuscular blocking agent used to produce muscular relaxation during general anaesthesia. (05 Mar 2000) |
| demecarium bromide | A potent cholinesterase inhibitor used in the treatment of glaucoma and accommodative esotropia; it is stable in aqueous solution. (05 Mar 2000) |
| domiphen bromide | Dodecyldimethyl(2-phenoxyethyl)ammonium bromide;an antiseptic. (05 Mar 2000) |
| oxyphenonium bromide | Diethyl(2-hydroxyethyl)methylammonium bromide alpha-phenyl-alpha-cyclohexylglycolate;a quaternary ammonium compound with anticholinergic action. (05 Mar 2000) |
| thonzonium bromide | Hexadecyl[2-[(p-methoxybenzyl)-2-pyrimidinylamino]ethyl]dimethylammonium bromide;a surface-active agent used in ear drops and aerosols. (05 Mar 2000) |
| ethidium bromide | <chemical, molecular biology> A dye that intercalates into DNA and to some extent RNA. Intercalation into linear DNA is easier than into circular DNA and the addition of ethidium bromide to DNA prior to ultracentrifugation on a caesium chloride gradient is much used to separate nuclear and mitochondrial or plasmid DNA for analytical purposes. Because less intercalates into the circular DNA, the density remains higher. (18 Nov 1997) |
| 2-hydroxy-5-nitrobenzyl bromide | <chemical> 2-(bromomethyl)-5-nitrophenol. A chemical reagent that reacts with and modifies chemically the tryptophan portion of protein molecules. Used for 'active site' enzyme studies and other protein studies. Sometimes referred to as koshland's reagent. Pharmacological action: indicators and reagents. Chemical name: Phenol, 2-(bromomethyl)-4-nitro- (12 Dec 1998) |
| lithium bromide | LiBr;a white deliquescent powder, used as a sedative and hypnotic. (05 Mar 2000) |
| active methyl | A methyl group attached to a quaternary ammonium ion or a tertiary sulfonium ion that can take part in transmethylation reactions; e.g., methyl groups in choline and in S-adenosyl-l-methionine, which are thus methyl donors. (05 Mar 2000) |
| aklanonic acid methyl ester cyclase | <enzyme> Catalyses the formation of aklaviketone from aklanonic acid methyl ester; involved in daunomycin biosynthesis; see also daunorubicin-doxorubicin polyketide synthase Registry number: EC 5.- Synonym: aame cyclase, daud protein, daud gene product, dnrd protein, dnrd gene product (26 Jun 1999) |
| alpha-(4-O-methyl)-D-glucuronidase | <enzyme> Removes 4-o-methyl-glucopyranosyl uronic acid residues from the 2-position of fungal cell wall xylans Registry number: EC 3.2.1.- Synonym: 4-o-methyl-glucuronidase (26 Jun 1999) |
| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |
| alpha methyl dopa | <drug> An antihypertensive drug, preferred in pregnant patients. (18 Nov 1997) |
| angular methyl | A methyl group attached to carbon 10 (between rings A and B) or to carbon 13 (between rings C and D) of the steroid nucleus. (05 Mar 2000) |
