Zur Pharmakokinetik von Lipidsenkern, 10. Mitt.: Zweiter Beitrag zur Frage der Dehalogenierung des Lipidsenkers Ciprofibrat

Abstract

rac-2 described as a metabolite of rac-1 was synthesized in four steps starting with rac-3. Partial dehalogenation occurs with LiAlH4. A new structure assignment of the resulting stereoisomers resulted from NMR spectroscopy. After oral administration of rac-1 in multiple dose studies to volunteers, rac-2 could not be detected within the limitations of sensitivity of HPLC (UV-detector) in plasma or in urine.
