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...
متن کاملIsolation and Structure Elucidation of Secondary Metabolites from Echinophora platyloba DC from Iran
Background: Echinophora platyloba DC (Apiaceae) is one of the two endemic species of Echinophora genus in Iran. It has many folkloric uses and several biological activities but there is no information about its phytoconstituents. Objective: In this work some of the secondary metabolites were isolated, purified and identified from n-hexane, ethyl acetate and methanol extracts from the aerial pa...
متن کاملFour butyrolactones and diverse bioactive secondary metabolites from terrestrial Aspergillus flavipes MM2: isolation and structure determination
The chemical constituents and biological activities of the terrestrial Aspergillus flavipes MM2 isolated from Egyptian rice hulls are reported. Seven bioactive compounds were obtained, of which one sterol: ergosterol (1), four butyrolactones: butyrolactone I (2), aspulvinone H (3), butyrolactone-V (6) and 4,4'-diydroxypulvinone (7), along with 6-methylsalicylic acid (4) and the cyclopentenone a...
