Abstract

In the present biotransformation study using human in vitro liver samples, metabolites of SDZ RAD were characterized by LC-MS. The major metabolites resulted from single hydroxylation and demethylation pathways and corresponded to the class of first-generation metabolites; 39-O-demethyl-RAD was identified as metabolite. The potential ring-opened degradation product resulting from ester hydrolysis and its dehydrated analogue (seco acid) was detected to comparable amounts in both the incubations and in controls without the presence of NADPH. The direct formation of rapamycin from SDZ RAD could not be detected in this study.
