Clinical Pharmacology and Therapeutics, 1984
Serum digoxin and metabolites were assayed in plasma and urine by HPLC in 10 dialysis-dependent patients with end-stage renal failure (group I) and in five patients with comparatively normal renal function (group II) after ingestion of 150 muCi 3H-digoxin-12 alpha.

Two healthy subjects took 3H-digoxigenin-12 alpha and unlabeled digoxigenin. Metabolites were assayed by high-pressure liquid chromatography (HPLC) in serum and urine. Of the tritium activity in the serum at 30 min, less than 26% chromatographed with digoxigenin; the rest chromatographed as metabolites, most of which were polar.

Planta Medica, 2012
Using a standard two-stage fermentation technique, the fungus Beauveria bassiana (ATCC 7159) was found to convert the eudesmanolide vulgarin (1) to 1α,4α-dihydroxy-5αH,6,11βH-eudesman-6,12-olide (2). The use of the yeastHansenula anomala ATCC 20170 instead, produced the less polar 4α-hydroxy-1-oxo-5αH,6,11βH-eudesman-6,12-olide(3), in addition to the ...

Toxicologic Pathology, 1988
About 4 million compounds have been described by chemists, and some 60,000 are presently on the market. The search for new chemicals with better properties and less toxicity continues, and future life quality will depend on our ability to find the safest compounds in each field of application.

Industrial carbohydrate biotransformations
Carbohydrate Research, 2008Nearly all major industrial processes which involve carbohydrates, include biotechnological transformations. This is due to the complex nature of carbohydrates where stereo- and regioselectivity are highly complex and difficult to control. Enzymes and microorganisms work highly selectively and efficiently in water solution, and provide high yield in ...

Biotechnology Advances, 2006
The main application of terpenes as fragrances and flavors depends on the absolute configuration of the compounds because enantiomers present different organoleptic properties. Biotransformations allow the production of regio- and stereoselective compounds under mild conditions. These products may be labeled as "natural".

Now in its seventh outstanding volume, Biotransformations has become established as a unique and important source for those involved in the discovery and development of new compounds. It broadly covers the scientific literature for the period 1987 to 1994. The series provides a complete survey of the biotransformations, in vertebrates, of the following:
