| theophylline sodium acetate | A mixture of theophylline sodium and sodium acetate, with 60% of theophylline; has the same uses as theophylline. (05 Mar 2000) |
|---|
| theophylline sodium glycinate | Equilibrium mixture containing theophylline sodium and glycine in approximately molecular proportions, buffered with an additional mole of glycine; similar in action and uses to aminophylline but more stable in air, and less irritating to the gastric mucosa. (05 Mar 2000) |
|---|---|
| sodium acetate | <chemical> The trihydrate sodium salt of acetic acid, which is used as a source of sodium ions in solutions for haemodialysis and peritoneal dialysis. It has also been used as a systemic and urinary alkaliser, diuretic, and expectorant. Pharmacological action: diuretics, expectorants, pharmaceutic aid. (12 Dec 1998) |
| theophylline | <drug> Inhibits cAMP phosphodiesterase and is often used in conjunction with exogenous dibutyryl cyclic AMP to raise cellular cAMP levels. Other, less potent, methylxanthines are caffeine, theobromine and aminophylline. (18 Nov 1997) |
| theophylline aminoisobutanol | <drug> A diuretic and bronchodilator. Synonym: theophylline aminoisobutanol. (05 Mar 2000) |
| theophylline calcium salicylate | A mixture of calcium theophylline and sodium salicylate in molecular proportion; has the same actions and uses as theophylline. (05 Mar 2000) |
| theophylline ethanolamine | Theophylline monoethanolamine, with the same actions and uses as theophylline. (05 Mar 2000) |
| theophylline ethylenediamine | <drug> An inhibitor of cAMP phosphodiesterase. (18 Nov 1997) |
| theophylline isopropanolamine | Has the same actions and uses as aminophylline, but a more rapid onset and a longer duration of action. (05 Mar 2000) |
| theophylline oxidase | <enzyme> Catalyses the oxidation of theophylline to 1,3-dimethyluric acid in the presence of ferricytochrome c Registry number: EC 1.5.99.- (26 Jun 1999) |
| acetate | <biochemistry> A salt or ester of acetic acid, specifically, a synthetic textile fibre made from partially hydrolysed cellulose acetate, or a plastic-like film made from cellulose triacetate. The terminal hydrogen atom in the molecule is replaced by a metal, for instance copper acetate, or where substitution is by a radical, for instance ethyl acetate. (04 Jul 1999) |
| acetate-CoA ligase | <enzyme> An enzyme that catalyses the formation of CoA derivatives from ATP, acetate, and CoA to form AMP, pyrophosphate, and acetyl CoA. It acts also on propionates and acrylates. Chemical name: Acetate:CoA ligase (AMP-forming) Registry number: EC 6.2.1.1 (12 Dec 1998) |
| acetate kinase | <enzyme> An enzyme that catalyses reversibly the phosphorylation of acetate in the presence of a divalent cation and ATP with the formation of acetylphosphate and ADP. It is important in the glycolysis process. Chemical name: ATP:acetate phosphotransferase Registry number: EC 2.7.2.1 (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| acetate-succinate CoA-transferase | <enzyme> Tritichomonas and trichomonas enzyme converts acetyl-CoA and succinate to acetate and succinyl-CoA Registry number: EC 2.8.3.- Synonym: acetate-succinate coenzyme a-transferase (26 Jun 1999) |
| acetate thiokinase | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
