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.

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.
