EPI-001 是一种选择性雄激素受体 (AR) 的抑制剂,靶向 AR 的反式激活单元 5 (Tau-5)。EPI-001 可抑制 AR 氨基末端结构域 (NTD) 的反式激活,IC50值约为 6 μM。EPI-001 也是一种选择性的PPARγ调节剂。EPI-001 对去势抵抗性前列腺癌具有活性。
生物活性 | EPI-001, a selective inhibitor ofAndrogen Receptor(AR), targets transactivation unit 5 (Tau-5) of the AR. EPI-001 can inhibit transactivation of the AR amino-terminal domain (NTD), with anIC50of ~6 μM. EPI-001 is also a selective modulator ofPPARγ. EPI-001 is active against castration-resistant prostatecancer[1][2][3]. |

体外研究 (In Vitro) | EPI-001 (5-100 μM; 7 d) inhibits PCa/CRPC cell growth in a dose-dependent manner[2]. EPI-001 (50 μM) inhibits endogenous AR mRNA and protein expression in PCa and CRPC cell lines[2]. EPI-001 (50 μM) inhibits transcriptional activity of both AR TAU1 and TAU5[2].
Cell Proliferation Assay[2] Cell Line: | PCa, CRPC, PC-3, DU 145, and T47D cell lines | Concentration: | 0, 5, 10, 25, 50, 100 μM | Incubation Time: | 7 days | Result: | Inhibited growth of LNCaP cells at low concentrations. Inhibited growth of AR-negative PC-3 and DU 145 cell lines as well as the T47D breast carcinoma cell line. |
Western Blot Analysis[2] Cell Line: | LNCaP, VCaP LAPC4, C4-2,22Rv1, and CWR-R1 cells | Concentration: | 50 μM | Incubation Time: | 8-16 hours | Result: | Decreased expression of full-length AR protein to varying degrees. |

体内研究 (In Vivo) | EPI-00 (20 mg/kg; i.v. every 5 d for 25 d) inhibits the growth of tumors and has no general toxicity in vivo[1]. EPI-00 (50 mg/kg; i.v.) blocks the androgen-axis and inhibits androgen-dependent tumor growth[1].
Animal Model: | Male NOD-SCID mice (6-8 weeks) bearing LNCaP[1] | Dosage: | 20 mg/kg | Administration: | I.v. every 5 days for 25 days | Result: | Reduced tumors from 100.3±1.72 mm3to 73.03±29.6 mm3within 2 weeks. Did not cause general toxicity indicated by no change in animal behavior or body weight. |
