Isolation and identification of two new nicotinamide metabolites.
Two previously unreported metabolites of nicotinamide have been discovered as urinary excretion products of rats following intraperitoneal injection of nicotinamide-7-i4C or nicotinic acid-7-W. These compounds have been identified as 6-hydroxynicotinamide and 6-hydroxynicotinic acid by comparison of ultraviolet, infrared, and mass spectra and behavior on chromatography and electrophoresis with ...
متن کاملSYNTHESIS OF NEW PHASE- 1 METABOLITES OF TWO BARBITURATES
The new 4'- hydroxy and 3'- aldehyde phase- 1 metabolites of butobarbitone and pentobarbitone are fully synthesized for the first time. These metabolites were used to idenfity and quantify the natural metabolites in human urine after single and multiple doses of these drugs. The synthesized metobolites have spectral characterizations (IR, NMR, U.V. and mass spectroscopy) consisted with the ...
متن کاملN-GLUCOSIDES: NEW PHASE-II METABOLITES OF TWO BARBITURATES
The new phase-II N-glucoside metabolites of butobarbitone and pentobarbitone are identified and quantified in human urine after single doses of these drugs. The identification and quantification of these metabolites were carried out by mass spectroscopy technique (accurate mass measurement and high voltage scanning). It was found that the butobarbitone N-glucoside comprised 26% of the dos...

15 صفحه اولon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
