| dimethyl ketone | <chemical> A colourless, flammable liquid which is used as a solvent (it is most familiar as the solvent in nail polish remover). The simplest ketone, it mixes with water, ethyl alcohol, and most oils. It melts at -95.4 deg C. And boils at 56.2 deg C. It is naturally found in very tiny quantities in the body fluids and tissues of healthy people and in somewhat larger amounts in people suffering from diabetes or starvation. (11 Mar 1998) |

| dimethyl phthalate | An insect repellent. (05 Mar 2000) |
| dimethyl suberimidate | <chemical> The methyl imidoester of suberic acid used to produce cross links in proteins. Each end of the imidoester will react with an amino group in the protein molecule to form an amidine. Pharmacological action: indicators and reagents. Chemical name: Octanediimidic acid, dimethyl ester (12 Dec 1998) |
| dimethyl sulfate | An industrial chemical (sulfuric acid dimethyl ester (CH3)2SO4), used in synthesis as an alkylating agent; it causes nystagmus, convulsions, and death from pulmonary complications. (05 Mar 2000) |
| dimethyl sulfoxide | <chemical> An alkyl sulfoxide that is practically odourless in its purified form. As a highly polar organic liquid, it is a powerful solvent. Its biologic activities include the ability to penetrate plant and animal tissues and to preserve living cells during freezing. It has been used investigationally as a topical analgesic and anti-inflammatory agent, and as an agent to increase the penetrability of other substances. It is available as a 50 percent solution for direct instillation into the bladder for treatment of interstitial cystitis. Pharmacological action: anti-inflammatory agent, topical, cryoprotective agents. Chemical name: Methane, sulfinylbis- (12 Dec 1998) |
| dimethyl sulfoxide reductase | <enzyme> From anaerobically grown E coli; reduced fmn and fad or methyl viologen can serve as electron donors Registry number: EC 1.8.99.- Synonym: dimethylsulfoxide reductase, dmso reductase, dora gene product (26 Jun 1999) |
| dimethyl sulphoxide | <chemical> A substance with the formula (CH3)2SO that is used as a cryoprotectant to protect cultured animal cells from the damaging effects of cryopreservation (storage by freezing). It is also used in transfection to increase the chances that the target eukaryotic cells will actually pick up, incorporate and express the DNA. (09 Oct 1997) |
| dimethyl tubocurarine chloride | Dimethyl ether of d-tubocurarine chloride; a skeletal muscle relaxant. See: tubocurarine chloride. (05 Mar 2000) |
| dimethyl tubocurarine iodide | (+)-O,O'-dimethylchondrocurarine diiodide;a nondepolarising neuromuscular blocking agent used to provide relaxation during surgical operations. Synonym: dimethyl d-tubocurarine, dimethyl tubocurarine iodide. (05 Mar 2000) |
| 6,7-dimethyl-8-ribityllumazine synthase | <chemical> Converts 5-amino-6-ribitylamino-2,4(1h,3h)-pyrimidinedione plus ribose 5-phosphate to an aliphatic intermediate which is converted to 6,7-dimethyl-8-ribityllumazine Chemical name: synthase, 6,7-dimethyl-8-ribityllumazine Synonym: 6,7-dmrl synthase, lumazine synthase (26 Jun 1999) |
| 9,10-dimethyl-1,2-benzanthracene | <chemical> 7,12-dimethylbenzanthracene. Polycyclic aromatic hydrocarbon found in tobacco smoke that is a potent carcinogen. Pharmacological action: carcinogens. Chemical name: Benz(a)anthracene, 7,12-dimethyl- (12 Dec 1998) |
