N-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 کاملCalcium signal modulators inhibit aerial mycelium formation in Streptomyces alboniger.
accelerated aerial mycelium formation in various actinomycete species, including S. alboniger. This induction was completely inhibited by ethylene glycol bis(/?-aminoethylether)-JV,N,N ',N '-tetraacetic acid (EGTA), a Ca2+-specific chelating agent. Ca2+ thus has been shown to play a role in aerial mycelium formation of 21 (58%) out of 36 strains of actinomycetes tested3). Ca2+ is known as a sec...
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 کاملThree new metabolites from Botrytis cinerea.
Three new metabolites, gamma-abscisolactone (1), botrytisic acids A (3) and B (4) were isolated from the fermentation broth of Botrytis cinerea TB-3-H8. Their structures were elucidated on the basis of MS, IR, UV, and NMR spectroscopic data. Compound 2 was isolated from natural resource for the first time. The structure of 1 was further confirmed by single-crystal X-ray diffraction (CCDC-265897).
متن کاملNew Secondary Metabolites from Croton sparsiflorus
The genus Croton belongs to the family Euphorbiaceae and comprises well over 1300 species growing as trees, shrubs, and herbs in tropical and subtropical regions of both hemispheres [1]. One of its species is Croton sparsiflorus (syn. C. bonplandianus) which is a shrub growing in sandy clay soil in Asia and South America [2]. It is used as a potent hypotensive agent [3] and for the treatment of...
