| 5-HT | 5-Hydroxy-Tryptamine = Serotonin |
| GSCN | giant serotonin-containing neuron |
| GSN | gelsonin; giant serotonin-containing neuron |
| beta-lactamase inhibitor | <pharmacology> Drugs such as clavulanic acid, which are used to inhibit bacterial beta-lactamases; often used with a penicillin or cephalosporin to overcome drug resistance. (05 Mar 2000) |
|---|---|
| Bowman-Birk inhibitor | A polypeptide that will inhibit both trypsin and chymotrypsin. (05 Mar 2000) |
| C1 esterase inhibitor | An a2-neuraminoglycoprotein that inhibits the enzymatic activity of C1 esterase, the activated first component of complement. A deficiency of this inhibitor results in a lack of inhibition of C1r and C1s leading to uncontrolled activation of the complement cascade and oedema. (05 Mar 2000) |
| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |
| carbonic acid inhibitor | <pharmacology> A group of diuretic medications which act to inhibit the enzyme carbonic anhydrase to create a metabolic acidosis. Many of these medications are used in the treatment of glaucoma. (27 Sep 1997) |
| carbonic anhydrase inhibitor | <pharmacology> A group of medications (sulphonamide drugs) which inhibit the enzyme carbonic anhydrase. These medications are used in the treatment of glaucoma. Examples include acetazolamide, dichlorphenamide and methazolamide. (27 Sep 1997) |
| mammary derived growth inhibitor | Fatty acid binding protein that inhibits proliferation of mammary carcinoma cells. (18 Nov 1997) |
| mechanism-based inhibitor | A competitive inhibitor that is converted to an irreversible inhibitor at the active site of the enzyme. Synonym: mechanism-based inhibitor. (05 Mar 2000) |
| glucosidase inhibitor | Agents such as acarbose which reduce gastrointestinal absorption of carbohydrates. This group of drugs has been known popularly as "starch blockers". They lower plasma glucose levels and tend to cause weight loss. A limiting side effect is flatulence. (05 Mar 2000) |
| medication, ace-inhibitor | Agents that inhibit ACE (angiotensin-converting enzyme), thereby acting as vasodilators (really as anti-vasoconstrictors), lightening the stress load on the heart. (12 Dec 1998) |
| residual inhibitor | A sound-generating device, worn in the ear, which inhibits or suppresses the sounds of tinnitus by masking, with a residual inhibitory effect when the device is turned off. (05 Mar 2000) |
| respiratory inhibitor | A compound that inhibits the respiratory chain. Synonym: respiratory poison. (05 Mar 2000) |
| cholinesterase inhibitor | <pharmacology> These are substances which which act to inhibit acetylcholinesterase, the enzyme which breaks down acetylcholine and thus enhance and subsequently prevent transmission of nerve impulses from one nerve cell to another or to a muscle. Examples include pyridostigmine, ambenonium and neostigmine. (15 Jan 1998) |
| monoamine oxidase inhibitor | <pharmacology> A drug that interferes with the action of monoamine oxidase, slowing the breakdown of certain neurotransmitters. Used in the treatment of depression. Monoamine oxidase inhibitors are a group of antidepressant drugs that prevent the activity of the enzyme monoamine oxidase in the central nervous system (brain) thus affecting mood. The use of these medications is often restricted due to their severe side effects and drug (and food) interactions. Examples include isocarboxazid, pargyline, selegiline, furazolidone and phenelzine. Acronym: MAOI (26 Mar 1998) |
| complement cytolysis inhibitor | <protein> Vertebrate glycoprotein of uncertain function. Secreted as a 400 amino acid peptide, then cleaved to form two 200 amino acid peptides that are linked by a disulphide bridge. Synonym: complement associated protein, complement cytolysis inhibitor, glycoprotein III. (11 Jan 1998) |
