生物活性
5α-Pregnane-3β,6α-diol-20-one 是一種促進(jìn)有絲分裂的 progesterone 代謝物，可于血清不足時(shí)雄性激素反應(yīng)的前列腺素癌細(xì)胞中產(chǎn)生。體外研究
Progesterone is converted to 5α-pregnane-3β,6α-diol-20-one in human fibroblasts. 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 relies on 3β-HSD activity.
