Galeterone (TOK-001) 是一种多功能的抗雄激素，是 CYP17 抑制剂，在去势抵抗性前列腺癌中，IC₅₀ 为 47 nM。

Galeterone (TOK-001) is a multifunctional antiandrogen and CYP17 inhibitor (IC 50 =47 nM) in castration resistant prostate cancer (CRPC).

IC50: 47 nM (CYP17)

Galeterone (TOK-001) affords strong CYP17 lyase inhibition, with IC50 of 47 nM. Galeterone (TOK-001) is both a CYP17A1 inhibitor and androgen receptor antagonist and the similarity of these binding modes is likely the reason for this dual mechanism of action.This CYP17A1 binds abiraterone and Galeterone (TOK-001) with absorbance decreases at 402 nm and increases at 424 nm, consistent with nitrogen binding to the heme iron (type II interaction) with Kd of <100 nM. When LNCaP cells are cultured in medium supplemented with charcoal-stripped serum (CSS, T<1 nM) followed by treatment with increasing concentrations of Galeterone (TOK-001), the steady-state levels of AR protein are markedly decreased (up to 84%, 15 μM Galeterone (TOK-001)). In LAPC-4 cells, abiraterone alcohol reduced AR expression to a greater extent than Galeterone (TOK-001) at concentra

Mice inoculated with LAPC-4 tumors are treated subcutaneously with 0.15 mmol/kg of Galeterone (TOK-001) twice daily. Mice treated with TOK-001 have smaller average tumor volume on day 31 when compared to control (p= 0.0001). Galeterone (TOK-001) treatment also significantly reduces the growth rate of tumor growth compared to control (p<0.0001). Upon excision, final tumor weights are also significantly reduced in animals treated with Galeterone (TOK-001) compared to animals treated with control, and castration (p<0.05). has not independently confirmed the accuracy of these methods. They are for reference only.
