- 1,1'-(2,2,2-Trichloroethylidene)-bis[4-chlorobenzene]
- [insecticide that came into prominence during and after World War II; for a time it proved very effective, but insect populations rapidly developed tolerance for it, hence much of its original effectiveness has been lost; general usage is now widely discouraged because of the toxicity that results from the environmental persistence of this agent.

- 1,1,2,2-Tetrachloroethylene
- [A colorless, volatile, nonflammable, liquid, chlorinated hydrocarbon with an ether-like odor that may emit toxic fumes of phosgene when exposed to sunlight or flames. Tetrachloroethylene is mainly used as a cleaning solvent in dry cleaning and textile processing and in the manufacture of fluorocarbons. Exposure to this substance irritates the upper respiratory tract and eyes and causes neurological effects as well as kidney and liver damage. Tetrachloroethylene is reasonably anticipated to be a human carcinogen and may be linked to an increased risk of developing skin, colon, lung, esophageal, and urogenital tract cancer as well as lymphosarcoma and leukemia. (NCI05) ( NCI )] (UMLS (NCI) C0039637) =Organic Chemical; Pharmacologic Substance; Hazardous or Poisonous Substance
- 1,1,2,2-Tetrafluoroethylene
- [A synthetic, colorless, flammable gas that is insoluble in water. Tetrafluoroethylene is used primarily in the synthesis of polytetrafluoroethylene resins. It is also used as a monomer in the synthesis of copolymers and as a propellant for food product aerosols. When heated to decomposition, tetrafluoroethylene emits highly toxic fluorocarbon fumes. The primary route of human exposure to this compound is inhalation. Acute inhalation exposure to tetrafluoroethylene may result in irritation of the respiratory tract and buildup of fluid in the lungs (pulmonary edema). Contact with this gas can cause eye irritation. This chemical is reasonably anticipated to be a human carcinogen. (NCI05) ( NCI )] (UMLS (NCI) C0076258) =Organic Chemical

- 1,2,3,4-tetrahydro-9-acridinamine Monohydrochloride Monohydrate
- [The hydrochloride salt form of tacrine, an aminoacridine derivative with cognitive stimulating property. Although the mechanism of action has not been fully elucidated, tacrine hydrochloride may bind reversibly to cholinesterase, acetylcholinesterase as well as butyrylcholinesterase, thereby decreasing the breakdown of acetylcholine, and prolonging synaptic actions as well as increased release of acetylcholine. In addition, this agent inhibits monoamine oxidase (MAO) and may inhibit the reuptake of catecholamines and serotonin. Finally, a novel mechanism of action studied in animal models suggests tacrine to attenuate the production of interleukin-1beta in the hippocampus and blood, thereby producing central and peripheral anti-inflammatory effects that may play a role in Alzheimer's disease.

- [A synthetic, colorless to light yellow liquid that is soluble in polar organic solvents and only slightly soluble in water. 1,2,3-Trichloropropane is used as both a chemical intermediate and cross-linking agent in the production of polymers. 1,2,3-Trichloropropane is flammable and, when heated to decomposition, emits toxic fumes of hydrogen chloride. Exposure of humans to 1,2,3-trichloropropane vapor causes irritation of the eyes and throat. It is reasonably anticipated to be a human carcinogen.

- 1,2,4-triazine-3,5(2H,4H)-dione, 2-beta-D-ribofuranosyl
- [A synthetic triazine nucleoside derivative possessing antineoplastic and anti-psoriatic activity. After metabolism to 6-azauridine-5-prime monophosphate, 6-Azauridine inhibits de novo pyrimidine biosynthesis and incorporates the 5-prime triphosphate metabolite into RNA, thereby preventing nucleic acid synthesis.

- [The hydrochloride salt form of trazodone, a synthetic triazolopyridine derivative with antidepressant and sedative properties. Based on studies from animal models, trazodone selectively inhibits the re-uptake of serotonin by synaptosomes in the brain, thereby increasing serotonin levels in the synaptic cleft and potentiating serotonin activity. Trazodone is not a monoamine oxidase inhibitor and, unlike amphetamine-type drugs, does not stimulate the central nervous system. The sedative effect of trazodone is likely via alpha-adrenergic and mild histamine H1 blocking actions.

- [An alpha-1-adrenergic antagonist that acts by blocking alpha-adrenergic receptors in the smooth muscle of blood vessels (arteries, arterioles and veins), gastrointestinal tract, and radial smooth muscle of the iris. This prevents smooth muscle contraction and results in vasodilatation. Administered in the eye, dapiprazole hydrochloride produces miosis. In the heart, it may antagonize alpha-1 adrenoreceptors in myocytes causing a mild negative inotropic effect.

- 2,3,4,5-tetrahydroxy-1,6- dioxido-hexane-1,6-dione, Calcium
- [The calcium salt form of glucaric acid, a natural substance found in many fruits and vegetables, with potential anti-cancer property. The active metabolite of calcium glucarate, D-Glucaro-1,4-Lactone in vivo, is an inhibitor of beta-Glucuronidase, an enzyme found in certain bacteria reside in the human gut. One of the key processes in which human body eliminates toxic chemicals as well as hormones (such as estrogen) is by attaching glucuronic acid to them in the liver and then excreting the complex in the bile. When beta-glucuronidase breaks the bond, it prolongs the stay of the hormone or toxic chemical in the body. Elevated beta-glucuronidase activity has been implicated to be associated with an increased risk for hormone-dependent cancers like breast, prostate, and colon cancers. Thereby, supplementing calcium glucarate may suppress the developments of hormone-dependent cancers. ( NCI )] (UMLS (NCI) C0006698) =Organic Chemical; Pharmacologic Substance ;;

- 3,4,4'-Trichlorodiphenylurea
- [A triclosan analogue with an antibacterial property. Triclocarban exerts its effect by inhibiting the activity of enoyl-(acyl-carrier protein) (ACP) reductase, widely distributed in bacteria, fungi and plants. ACP reductase catalyses the last step in each cycle of fatty acid elongation in the type II fatty acid synthase systems. As a result, this agent interupts cell membrane synthesis and leads to bacterial growth inhibition. ( NCI )] (UMLS (NCI) C0077072) =Organic Chemical; Pharmacologic Substance
