11-Ketodihydrotestosterone (11-KDHT; 5α-Dihydro-11-keto testosterone) 是一种内源性类固醇，是 11β-羟基雄烯二酮的代谢产物。11-Ketodihydrotestosterone 是一种活性雄激素，也是一种有效的雄激素受体 (AR) 激动剂，对人 AR 的 K_i 为 20.4 nM，EC₅₀ 为 1.35 nM。11-Ketodihydrotestosterone 在雄激素依赖性前列腺癌细胞中诱导基因调节，蛋白质表达和细胞生长。

11-Ketodihydrotestosterone (11-KDHT; 5α-Dihydro-11-keto testosterone) is an endogenous steroid and a metabolite of 11β-Hydroxyandrostenedione. 11-Ketodihydrotestosterone is an active androgen and is also a potent androgen receptor (AR) agonist with a K i of 20.4 nM and an EC 50 of 1.35 nM for human AR. 11-Ketodihydrotestosterone drives gene regulation, protein expression and cell growth in androgen-dependent prostate cancer cells.

11-Ketodihydrotestosterone (11-KDHT; 1-10 nM; 24 hours; LNCaP and VCaP cells) treatment induces significant cell proliferation.
11-Ketodihydrotestosterone (11-KDHT; 0.1-10 nM; 7-10 days; LNCaP and VCaP cells) treatment results in the significant upregulation of KLK3 , TMPRSS2 and FKBP5 in both LNCaP and VCaP cells, with the exception of KLK3 at 1 nM in LNCaP cells.
In PNT2 cells, only 20% of 11β-hydroxyandrostenedione (11OHA4) and 11β-hydroxytestosterone (11OHT) are metabolised with the former yielding 11keto-androstenedione (11KA4), 11-Ketodihydrotestosterone (11-KDHT) and 11β-hydroxy-5α-androstanedione (11OH-5αDIONE) and the latter yielding 11OHA4, 11KT and 11-Ketodihydrotestosterone with downstream products <0.03 μM.
In prostate cancer tissue, C11-oxy C19 metabolites at significantly higher levels than the C19 steroids are detected,

Room temperature in continental US; may vary elsewhere.
