| 4-aminobenzoic acid | <chemical> 4-aminobenzoic acid. A member of the vitamin b complex. It is also employed as a sunscreening agent. The potassium salt is used therapeutically in fibrotic skin disorders. Pharmacological action: sunscreening agents. Chemical name: Benzoic acid, 4-amino- (12 Dec 1998) |
| 4-aminobutyrate pathway | The pathway that ultimately converts 4-aminobutyrate to succinate; succinate is then converted to alpha-ketoglutarate, via the tricarboxylic acid cycle, which is then acted upon by glutamate dehydrogenase; glutamate is then decarboxylated to reform 4-aminobutyrate; an important pathway for those cells which make this neuroactive molecule. Synonym: GABA pathway. (05 Mar 2000) |
| 4-aminobutyrate transaminase | <enzyme> An enzyme that converts brain gamma-aminobutyric acid (gaba) into succinate saemialdehyde, which can be converted to succinic acid and enter the citric acid cycle. It also acts on beta-alanine. Chemical name: 4-Aminobutanoate:2-oxoglutarate aminotransferase Registry number: EC 2.6.1.19 (12 Dec 1998) |
| 4-aminopyridine | <chemical> A potassium channel blocker. It is used primarily as a research tool and is helpful in characterizing subtypes of potassium channels. It has been used clinically in lambert-eaton syndrome and multiple sclerosis because by blocking potassium channels it prolongs action potentials thereby increasing transmitter release at the neuromuscular junction (and elsewhere). Chemical name: 4-Pyridinamine (12 Dec 1998) |
| 4-androstene-3,17-dione-16 beta-hydroxylase | <enzyme> Catalyses androst-4-en-3,17-dione to 16 beta-hydroxyandrost-4-en-3,17-dione; cytochrome p450 2b1 is both a androstenedione 16beta-hydroxylase and a testosterone 16beta-hydroxylase Registry number: EC 1.14.99.- Synonym: aedo-16-hydroxylase, steroid 16-hydroxylase, cytochrome p450 2b2, cyp 2b2, cyp2b2 (26 Jun 1999) |
| 4-butyrolactone | <chemical> Dihydro-2(3h)-furanone. An endogenous compound, made from gamma-aminobutyrate and the precursor of gamma-hydroxybutyrate, it is also used as a pharmacological agent. It apparently acts as a modulator at the picrotoxin binding site of gaba-a receptors, and may also affect gaba-b receptors. It is used mainly as an experimental tool. Among other systemic effects, it causes increase of brain dopamine by inhibiting its release from nerve terminals. It is also used as an industrial solvent and precursor. Pharmacological action: gaba modulators, solvents. Chemical name: 2(3H)-Furanone, dihydro- (12 Dec 1998) |
| 4-carboxyglutamic acid | A carboxylated form of glutamic acid found in certain proteins (e.g., prothrombin, factors VII, IX, and X, osteocalcin). Its synthesis is vitamin K-dependent. (05 Mar 2000) |
