barbituric การใช้

• The equilibrium of the reaction favors the formation of barbituric acid.
• Barbiturase is very specific to barbituric acid and will not react with derivatives.
• Urea, malonate, and cyanuric acid inhibit the hydrolysis of barbituric acid.
• In addition, barbituric acid inhibits multiple enzymes that are involved in de novo pyrimidine synthesis.
• Barbiturates are derivatives of barbituric acid.
• It is a common reagent for organic synthesis used, for example, as a precursor for barbituric acid.
• Which is a multicomponent reaction of N, N'- dimethyl-barbituric acid, benzaldehyde and ethyl vinyl ether.
• In 1903, he published observations that barbital ( then known as diethyl-barbituric acid ) has sedative properties in humans.
• In 1912, Bayer introduced another barbituric acid derivative, phenobarbital, under the trade name Luminal, as a sedative-hypnotic.
• The species is prepared by addition of ammonia to o-phthalonitrile to give the diiminoisoindoline, which in turn condenses with barbituric acid.
• I'm trying to figure out why dimedone is almost as acidic as barbituric acid, compared to other diketones ( 3 pKa drop ).
• Another proposed use of physostigmine is to reverse the effects of barbiturates ( any of a group of barbituric acids derived for use as sedatives or hypnotics ).
• Regarding barbituric acid, was it ever proven whether the reported thermodynamic pKa is actually for the doubly-? position rather than an amide N-H?
• A mixture containing citric acid, monopotassium phosphate, boric acid, and diethyl barbituric acid can be made to cover the pH range 2.6 to 12.
• Barbituric acid itself does not have any direct effect on the central nervous system and chemists have derived over 2, 500 compounds from it that possess pharmacologically active qualities.
• This yellow green compound is prepared by addition of ammonia to o-phthalonitrile to give the diiminoisoindoline, which in turn condenses first with N-methylcyanoacetamide and then with barbituric acid.
• About the program : Includes seven nights'accommodation at Barbituric Belagaggio in Montefollonico; all meals for five days, including wine, olive oil and cheese tastings; visits to local markets and historical towns.
• Barbiturates can in most cases be used either as the free acid or as salts of sodium, calcium, potassium, magnesium, lithium, etc . Codeine-and Dionine-based salts of barbituric acid have been developed.
• One thing I've been thinking about is homoaromaticity ( and the aromaticity-stabilisation for barbituric acid probably is significantly reduced because of the number of heteroatoms and EWGs involved ) . talk ) 17 : 23, 25 April 2010 ( UTC)
