| chromogenic compounds | Colourless, endogenous or exogenous pigment precursors that may be transformed by biological mechanisms into coloured compounds; used in biochemical assays and in diagnosis as indicators, especially in the form of enzyme substrates. Synonym: chromogens (not to be confused with pigment-synthesizing bacteria also called chromogens). (12 Dec 1998) |
|---|---|
| phenylmercury compounds | <chemical> Organic mercury compounds in which the mercury is attached to a phenyl group. Often used as fungicides and seed treatment agents. Pharmacological action: fungicides, industrial. (12 Dec 1998) |
| ruthenium compounds | Inorganic compounds that contain ruthenium as an integral part of the molecule. (12 Dec 1998) |
| phosphorus compounds | Inorganic compounds that contain phosphorus as an integral part of the molecule. (12 Dec 1998) |
| platinum compounds | Inorganic compounds which contain platinum as the central atom. (12 Dec 1998) |
| mustard compounds | Strong alkylating and immunosuppressive agents whose biological activity is based on the presence of bis(2-chloroethyl)- groups. Although otherwise structurally diverse, the compounds have in common the capacity to contribute alkyl groups to DNA. They are generally highly toxic but include among their number many widely used and effective antineoplastic agent. (12 Dec 1998) |
| polychloroterphenyl compounds | Compounds consisting of three benzene rings linked to each other in either ortho, meta or para positions and substituted with chlorine atoms. (12 Dec 1998) |
| potassium compounds | Inorganic compounds that contain potassium as an integral part of the molecule. (12 Dec 1998) |
| pralidoxime compounds | Various salts of a quaternary ammonium oxime that reconstitute inactivated acetylcholinesterase, especially at the neuromuscular junction, and may cause neuromuscular blockade. They are used as antidotes to organophosphorus poisoning as chlorides, iodides, methanesulfonates (mesylates), or other salts. (12 Dec 1998) |
| heterocyclic compounds | Ring compounds having atoms other than carbon in their nuclei. (12 Dec 1998) |
| heterocyclic compounds, 1-ring | A class of organic compounds containing a ring structure made up of more than one kind of atom, usually carbon plus another atom. The ring structure can be aromatic or nonaromatic. (12 Dec 1998) |
| heterocyclic compounds, 2-ring | A class of organic compounds containing two ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic. (12 Dec 1998) |
| heterocyclic compounds, 3-ring | A class of organic compounds containing three ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic (12 Dec 1998) |
| heterocyclic compounds, bridged-ring | A class of organic compounds which contain two rings that share a pair of bridgehead carbon atoms. (12 Dec 1998) |
| heterocyclic compounds with 4 or more rings | A class of organic compounds containing four or more ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic. (12 Dec 1998) |
