The fate of[14C]thalidomide in the pregnant rabbit.
1. The fate of [(14)C]thalidomide orally administered to pregnant rabbits at the beginning of the sensitive phase of pregnancy has been studied. 2. After the oral administration of [(14)C]thalidomide on the 192nd hour of pregnancy about 68% of the radioactivity appears in the urine and 22% in the faeces. 3. The urinary (14)C is made up as follows (% of dose): thalidomide (2); alpha-(o-carboxybe...
متن کاملThe fate of 14C in glucose 6-phosphate synthesized from [1-14C]Ribose 5-phosphate by enzymes of rat liver.
1. Glucose 5-phosphate was synthesized from ribose 5-phosphate by an enzyme extract prepared from an acetone-dried powder of rat liver. Three rates of ribose 5-phosphate utilization were observed during incubation for 17 h. An analysis of intermediates and products formed throughout the incubation revealed that as much as 20% of the substrate carbon could not be accounted for. 2. With [1-14C]ri...
متن کاملMetabolic fate of 14C-labelled nicotinamide and adenine in germinating propagules of the mangrove Bruguiera gymnorrhiza.
We studied the metabolic fate of [carbonyl-14C]nicotinamide and [8-(14)C]adenine in segments taken from young and developing leaves, stem, hypocotyls, and roots of a shoot-root type emerging propagule of the mangrove plant Bruguiera gymnorrhiza. Thin-layer chromatography was used together with a bioimaging analyser system. During 4 h of incubation, incorporation of radioactivity from [carbonyl-...
متن کاملFate of organochlorine 14C-dicofol in a lab-scale wastewater treatment
The fate of organochlorine (14)C-dicofol in activated sludge process was investigated. Results showed that the major part of radioactivity remained adsorbed on biological sludge. Consequently, its final disposal deserves special attention. The small amounts of dicofol, biotransformed or not, which remained in the treated effluent could contaminate receiving bodies.
متن کاملEnantioselective hydrolysis of racemic naproxen nitrile and naproxen amide to S-naproxen by new bacterial isolates.
Bacteria were enriched from soil samples with succinate as a carbon source and racemic naproxen nitrile [2-(6-methoxy-2-naphthyl)propionitrile] as sole source of nitrogen. Since naproxen nitrile was only poorly soluble in water media amended with different water-immiscible organic phases were used for the enrichments. With pristane (2,6,10,14-tetramethylpentadecane) as the organic phase two bac...
