Human cytochrome P450 3A4 forms a series of minortestosterone hydroxylation products in addition to 6b-hy-droxytestosterone, the major product. One of these, formedat the next highest rate after the 6b-and 2b-hydroxy prod-ucts, was identified as 1b-hydroxytestosterone. This productwas characterized from a mixture of testosterone oxidationproducts using an HPLC-solid phase extraction-cryoprobeNMR/time-of-flight mass spectrometry system, with anestimated total of6lgof this product.Mass spectrometryestablished the formula as C19H29O3(MH+305.2080)....
