Sigma KEE - BiologicallyActiveSubstance
KB Term: 
A Substance that is capable of inducing a change in the structure or functioning of an Organism. This Class includes Substances used in the treatment, diagnosis, prevention or analysis of normal and abnormal body function. This Class also includes Substances that occur naturally in the body and are administered therapeutically. Finally, BiologicallyActiveSubstance includes Nutrients, most drugs of abuse, and agents that require special handling because of their toxicity.
Parents Substance An Object in which every part is similar to every other in every relevant respect. More precisely, something is a Substance when it has only arbitrary pieces as parts - any parts have properties which are similar to those of the whole. Note that a Substance may nonetheless have physical properties that vary. For example, the temperature, chemical constitution, density, etc. may change from one part to another. An example would be a body of water.
Children AlkaloidA ChemicalBase found in Plants that has physiological and psychological effects.
 AntibioticA BiologicallyActiveSubstance than can kill instances of Bacterium.
 AntigenAny BiologicallyActiveSubstance that has the capacity to stimulate the production of Antibodies.
 AtropineAn anticholinergic agent.
 BiochemicalAgentA BiologicalAgent or a ChemicalAgent.
 ChemicalAgentSynthetic compounds that are not an analogue of anything occurring naturally and that can result in serious burns, paralysis, and death to Organisms.
 ControlledSubstanceControlledSubstance is the subclass of BiologicallyActiveSubstances whose distribution and use is controlled by government regulation.
 CSGas2-chlorobenzalmalononitrile (chemical formula: C10H5ClN2) is a substance that is used as a riot control agent and is usually claimed to be non-lethal by the forces who use it. CS was discovered by two Americans, Ben Carson and Roger Staughton in 1928, the first letters of the scientists' surname giving us the name of the substance, 'CS' [4]. It was developed and tested secretly at Porton Down in Wiltshire, England. Apparently this testing occurred in the 1950s and 1960s when CS was used firstly on animals, then subsequently on British Army servicemen volunteers. Notably CS has a limited effect on animals due to under-developed tear-ducts and protection by fur. [5]. (from Wikipedia). Known as tear or pepper gas, often used by paramilitary and police to control unruly crowds, the gas can cause temporary blindness and tearing.
 DepressantAny BiologicallyActiveSubstance which has the effect of depressing the central nervous system, i.e. decreasing function or activity in the Brain or SpinalCord.
 DimercaprolA chelating agent often used to treat Lewisite, as well as Lead Poisoning.
 HormoneIn Animals, a chemical secreted by an endocrine gland whose products are released into the circulating fluid. Plant hormones or synthetic hormones which are used only to alter or control various physiologic processes, e.g., reproductive control agents, are assigned to the Class BiologicallyActiveSubstance. Hormones act as chemical messengers and regulate various physiologic processes such as growth, reproduction, metabolism, etc. They usually fall into two broad categories, viz. steroid hormones and peptide hormones.
 MedicineAny BiologicallyActiveSubstance which has a therapeutic effect under certain conditions.
 NutrientA BiologicallyActiveSubstance required by an Organism. It is generally ingested as Food, and it is of primary interest because of its role in the biologic functioning of the Organism.
 OpiumA substance harvested from the seed capsules of the opium poppy that contains various powerful alkaloids.
 PyrethrumPyrethrum is the subclass of BiologicallyActiveSubstance consisting of insecticidal derivations from the flower heads of Chrysanthemums.
 PyridostigmineBromideA substance that has been shown to protect lower primates from the lethal effects of Soman. Although there is no proof that it does the same for humans, it was administered to soldiers in the Gulf War.
 SteroidA class of OrganicCompounds having the same basic chemical structure and having significant physiological effects.
 StimulantAny BiologicallyActiveSubstance which has the effect of stimulating the central nervous system, i.e. increasing function or activity in the Brain or SpinalCord.
 ToxinBiologicalAgents that are a toxic BiologicallyActiveSubstance produced by an Organism or that are the synthetic analogue of a toxic BiologicallyActiveSubstance produced by an Organism.
