| Description | 5α-Pregnane-3β,6α-diol-20-one is a mitogenic metabolite derived from progesterone, capable of being synthesized by androgen-responsive prostate cancer cells under conditions of starvation. |
| In vitro | Progesterone is converted to 5α-pregnane-3β,6α-diol-20-one in human fibroblasts [1]. Pregnenolone and progesterone are avidly metabolized to 5α-pregnan-3β,6α-diol-20-one in the C4.2 cell line, with nearly complete conversions at 24 h and 18 h, respectively. Preferential 5α-pregnan-3β,6α-diol-20-one formation from early steroid precursors is independent of CYP17A1 but rather dependent on 3β-HSD activity [2]. |
