| uracil mustard | <chemical> Nitrogen mustard derivative of uracil. It is a alkylating antineoplastic agent that is used in lymphatic malignancies, and causes mainly gastrointestinal and bone marrow damage. Pharmacological action: antineoplastic agent, alkylating. Chemical name: 2,4(1H,3H)-Pyrimidinedione, 5-(bis(2-chloroethyl)amino)- (12 Dec 1998) |

| uracil | <biochemistry> The pyrimidine base from which uridine is derived. (18 Nov 1997) |
|---|---|
| uracil-6-carboxylic acid | Intermediate in the de novo synthesis of pyrimidines. Linked glycosidically to ribose 5' phosphate, orotate forms the pyrimidine nucleotide orotidylate, that on decarboxylation at position 5 of the pyrimidine ring yields the major nucleotide uridylate (uridine 5' phosphate). (18 Nov 1997) |
| uracil dehydrogenase | An oxidoreductase catalyzing oxidation of uracil to barbituric acid; also oxidises thymine. Synonym: uracil oxidase. (05 Mar 2000) |
| uracil-DNA glycosidase | <enzyme> Catalyses hydrolysis of n-glycosidic bond of damaged nucleotide residues to give free uracil and partly depyrimidinated DNA of unaltered chain length; does not cleave phosphodiester bonds; a DNA repair enzyme Registry number: EC 3.2.2.- Synonym: ura-DNA glycosidase, uracil-DNA glycosylase, uracil n-glycosidase, ura-DNA glycosylase, uracil n-glycosylase (26 Jun 1999) |
| uracil oxidase | An oxidoreductase catalyzing oxidation of uracil to barbituric acid; also oxidises thymine. Synonym: uracil oxidase. (05 Mar 2000) |

| uracil phosphoribosyltransferase | See: phosphoribosyltransferase. (05 Mar 2000) |
| aniline mustard | <chemical> N,n-bis(2-chloroethyl)aniline. Alkylating anti-neoplastic agent effective in some mouse tumours, but less useful in man. Pharmacological action: antineoplastic agent, alkylating. Chemical name: Benzenamine, N,N-bis(2-chloroethyl)- (12 Dec 1998) |
| black mustard | The dried ripe seed of Brassica nigra or of B. Juncea; it is the source of allyl isothiocyanate; it contains sinigrin (potassium myronate); myrosin; sinapine sulfocyanate; erucic, behenic, and synapolic acids; and fixed oil; a prompt emetic, a rubefacient, and a condiment. (05 Mar 2000) |
| volatile mustard oil | CH2==CH-CH2-NCS; volatile mustard CH-allylisosulfocyanate; isothiocyanic allyl ester;obtained from Brassica nigra or produced synthetically; a vesicant, used in 10% solution in 50% alcohol as a counterirritant in neuralgia. Gives mustard its characteristics flavor and aroma. See: mustard oil. Synonym: volatile mustard oil. (05 Mar 2000) |
| white mustard | The ripe seeds of Brassica (Sinapis) alba; less pungent than black mustard, but with the same constituents and uses. (05 Mar 2000) |
| mustard | 1. <botany> The name of several cruciferous plants of the genus Brassica (formerly Sinapis), as white mustard (B. Alba), black mustard (B. Nigra), wild mustard or charlock (B. Sinapistrum). There are also many herbs of the same family which are called mustard, and have more or less of the flavor of the true mustard; as, bowyer's mustard (Lepidium ruderale); hedge mustard (Sisymbrium officinale); Mithridate mustard (Thlaspi arvense); tower mustard (Arabis perfoliata); treacle mustard (Erysimum cheiranthoides). 2. A powder or a paste made from the seeds of black or white mustard, used as a condiment and a rubefacient. Taken internally it is stimulant and diuretic, and in large doses is emetic. Origin: OF. Moustarde, F. Moutarde, fr. L. Mustum must, mustard was prepared for use by being mixed with must. See Must. Source: Websters Dictionary (01 Mar 1998) |
| mustard chlorohydrin | 2-(2-chloroethylthio)ethanol An antineoplastic agent. Synonym: mustard chlorohydrin, semisulfur mustard. (05 Mar 2000) |
| 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) |
| mustard gas | <chemical> 1,1'-thiobis(2-chloroethane). Severe irritant and vesicant of skin, eyes, and lungs. It may cause blindness and lethal lung oedema and was formerly used as a war gas. The substance has been proposed as a cytostatic and for treatment of psoriasis. It has been listed as a known carcinogen in the fourth annual report on carcinogens (ntp-85-002, 1985) (merck, 11th ed). Pharmacological action: carcinogens, chemical warfare agents, dermatologic agents. Chemical name: Ethane, 1,1'-thiobis(2-chloro- (12 Dec 1998) |
