What's the difference between aniline and violaniline?

Aniline


Definition:

  • (n.) An organic base belonging to the phenylamines. It may be regarded as ammonia in which one hydrogen atom has been replaced by the radical phenyl. It is a colorless, oily liquid, originally obtained from indigo by distillation, but now largely manufactured from coal tar or nitrobenzene as a base from which many brilliant dyes are made.
  • (a.) Made from, or of the nature of, aniline.

Example Sentences:

  • (1) Pretreatment of rats with 6-(3-picolyl)amino-2,2,5,8-tetramethylchromane (PATC) for 7 days resulted in a significant increase in the activities of benzphetamine N-demethylase, p-nitroanisole O-demethylase and aniline hydroxylase in liver microsomes prepared 24 h after the last treatment.
  • (2) Comparison of the specific activities for aniline hydroxylation and p-nitrophenol hydroxylation of individual microsomal samples from control, ethanol-pretreated and phenobarbital-pretreated animals showed a high degree of correlation (r2 = 0.98) consistent with the involvement of the same site for catalysis of these two compounds.
  • (3) Chlordimeform had no effect on the cytochrome P-450 content, aniline p-hydroxylase or glutathione S-transferase activities, but induced ethoxyresorufin-O-deethylase, ethoxycoumarin-O-deethylase and epoxide hydrolase activities and decreased aldrin epoxidase and aminopyrine N-demethylase activities.
  • (4) Intestinal aniline hydroxylation was refractory to ethanol induction.
  • (5) Incubation of aniline-metabolizing hepatocytes with disulfiram resulted in decreased formation of 4-aminophenol, but this was not associated with impaired glucuronidation or cytochrome P-450 levels.
  • (6) At 20 degrees C, in a phosphate buffer, pH 5,8--8,0, methanol and aniline interactions with hemoglobin and cytochrome c were studied using the difference spectrophotometry method.
  • (7) Activities of amidopyrine N-demethylase, aniline hydroxylase, NADPH, cytochrome c reductase as well as content of cytochromes P-450 and b5 were studied in liver tissue of rats within 1, 3, 7, 10, 20 and 30 days of hypokinesia caused by maintaining of the animals in individual cell-cases.
  • (8) In contrast, menadione does not change the type II binding spectrum induced by aniline.
  • (9) Enzymatic polymerization took place on the surface of BOD-adsorbed solid matrix which was in contact with a buffer solution containing aniline.
  • (10) In NADPH-containing microsomal systems with 4-fluoro-substituted anilines, formation of the 4-hydroxyaniline derivative is observed because NADPH chemically reduces this quinoneimine metabolite.
  • (11) The activity of aniline hydroxylase was significantly increased in liver microsomes of EHBR whereas the activity of ethylmorphine N-demethylase was found to be significantly decreased in EHBR as compared to control rats.
  • (12) When compared to the first day, methemoglobin (MetHb) levels, measured prior to and following the exposure, increased with the days of exposure at 50 ppm aniline.
  • (13) Although metabolic attack occurred adjacent to either the aniline nitrogen or the aliphatic amine, metabolic attack occurred primarily adjacent to the more basic nitrogen at the 1'-position, even when this position bore a methyl substituent.
  • (14) Carbon monoxide inhibits the hydroxylase activity of the tissue-free system to a smaller extent than that of a system containing microsomes plus haemoglobin whereas p-chloromercuribenzoate inhibits only the flavoprotein-dependent hydroxylation of aniline mediated by haemoglobin.
  • (15) The profiles of urinary metabolites produced by rats and mice were not appreciably different in animals predosed with aniline.
  • (16) The results indicate that aniline degrading populations of these various microbial communities exhibit different activities probably depending on the extent of adaptation to pollutants to which the microbes are exposed.
  • (17) A high-pressure liquid chromatographic method has been developed for the determination of nanomole quantities of aniline; its metabolites o- and p-aminophenol, phenylhydroxylamine, nitrosobenzene and nitrobenzene; and azobenzene and azoxybenzene which form non-enzymatically by condensation of reactive metabolites.
  • (18) A series of ortho-quinone analogues 1-28 of podophyllotoxin possessing various C-4 beta-aniline moieties have been synthesized and evaluated for their inhibitory activity against human DNA topoisomerase II, their activity in causing cellular protein-linked DNA breakage, and their cytotoxicity against KB cells.
  • (19) The inhibitory effect of the nitroso-compound is demonstrated to be non-competitive on aminopyrine N-demethylase, p-nitroanisole O-demethylase and aniline hydroxylase.
  • (20) Compared with the control values, the levamisole treatment significantly increased the amount of cytochrome P450 and cytochrome b5 and the in-vitro activities of aminopyrine N-demethylase, benzphetamine N-demethylase and aniline hydroxylase.

Violaniline


Definition:

  • (n.) A dyestuff of the induline group, made from aniline, and used as a substitute for indigo in dyeing wool and silk a violet-blue or a gray-blue color.
