|---|---|
| methoxychlor | <chemical> An insecticide. Methoxychlor has oestrogenic effects in mammals, among other effects. Pharmacological action: insecticide, organochlorine. Chemical name: Benzene, 1,1'-(2,2,2-trichloroethylidene)bis(4-methoxy- (12 Dec 1998) |
| methoxydimethyltryptamines | Compounds that contain the biogenic monoamine tryptamine and are substituted with one methoxy group and two methyl groups. Members of this group include several potent serotonergic hallucinogens found in several unrelated plants, skins of certain toads, and in mammalian brains. They are possibly involved in the aetiology of schizophrenia. (12 Dec 1998) |
| methoxyflurane | <chemical> An inhalation anaesthetic. Currently, methoxyflurane is rarely used for surgical, obstetric, or dental anaesthesia. If so employed, it should be administered with nitrous oxide to achieve a relatively light level of anaesthesia, and a neuromuscular blocking agent given concurrently to obtain the desired degree of muscular relaxation. Pharmacological action: anaesthetics, inhalation. Chemical name: Ethane, 2,2-dichloro-1,1-difluoro-1-methoxy- (12 Dec 1998) |
| methoxyflurane defluorinase | <enzyme> Metabolises methoxyflurane, isoflurane or enflurane enzyme induction with phenobarbital to inorganic fluorides. Registry number: EC 1.- (26 Jun 1999) |
| methoxyhydroxyphenylglycol | <chemical> 1-(4-hydroxy-3-methoxyphenyl)-1,2-ethanediol. Synthesised by animals from endogenous epinephrine and norepinephrine. It is found in brain, blood, csf, and urine, where its concentrations are used to measure catecholamine turnover. Chemical name: 1,2-Ethanediol, 1-(4-hydroxy-3-methoxyphenyl)- (12 Dec 1998) |
| methoxyl | <chemistry> A hypothetical radical, CH3O, analogous to hydroxyl. Source: Websters Dictionary (01 Mar 1998) |
| methoxyneurosporene dehydrogenase | <enzyme> From rhodobacter sphaeroides; involved in later stages of carotenoid biosynthesis Registry number: EC 1.- Synonym: crtd gene product (26 Jun 1999) |
| methoxyphenamine hydrochloride | Beta-(o-Methoxyphenyl)isopropylmethylamine hydrochloride;a sympathomimetic amine. (05 Mar 2000) |
| methoxyresorufin-O-demethylase | <enzyme> A monooxygenase that is supported by both p4501a1 and p4501a2 Registry number: EC 1.- Synonym: mrod (26 Jun 1999) |
| S-adenosyl-L-methionine-2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone-O-methyltransferase | <enzyme> Proposed pathway for final reaction in ubiquinone biosynthesis. Registry number: EC 2.1.1.- Synonym: 2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone methyltransferase, ubig gene product, ubig protein (26 Jun 1999) |

| 3-methoxy-4-hydroxymandelic acid | Misnomer for 4-hydroxy-3-methoxymandelic acid (a,3-dihydroxy-2-methoxybenzeneacetic acid);the major urinary metabolite of adrenal and sympathetic catecholamines (e.g., from both epinephrine and norepinephrine); elevated in most patients with pheochromocytoma. Acronym: VMA (05 Mar 2000) |
| 3-methoxy-4-hydroxymandelic acid test | A test for catecholamine-secreting tumours (pheochromocytoma and neuroblastoma) performed on a 24-hr urine specimen; it is based on the fact that vanillylmandelic acid is the major urinary metabolite of norepinephrine and epinephrine. Synonym: 3-methoxy-4-hydroxymandelic acid test, VMA test. (05 Mar 2000) |
| 3-methoxy-4-hydroxyphenylethanol | <chemical> 3-methoxy-4-hydroxyphenylethanol. Metabolite of serotonin and norepinephrine. Chemical name: Benzeneethanol, 4-hydroxy-3-methoxy- (12 Dec 1998) |
