产品介绍
UT-34 是一种有效的,选择性的,具有口服活性的第二代泛雄激素受体 (AR) 拮抗剂和降解剂,对野生型ARF876L-ARW741L-ARIC50分别为 211.7 nM,262.4 nM 和 215.7 nM。UT-34 与配体结合结构域 (LBD) 和功能 1 (AF-1) 结构域结合,并需要泛素蛋白酶体途径来降解AR。UT-34 具有抗前列腺癌的功效。
生物活性

UT-34 is a potent, selective and orally active second-generation pan-androgen receptor(AR)antagonist and degrader withIC50s of 211.7 nM, 262.4 nM and 215.7 nM forwild-type,F876LandW741L AR, respectively. UT-34 binds to ligand-binding domain (LBD) and function-1 (AF-1) domains and requires ubiquitinproteasomepathway to degrade theAR. UT-34 has anti-prostatecancerefficacy[1][2].

IC50& Target

IC50: 211.7 nM (Wild-type AR), 262.4 nM (F876L AR) and 215.7 nM (W741L AR)[1]

体外研究
(In Vitro)

UT-34 (3-10 μM; 24 hours; LNCaP cells) treatment inhibits the expression of PSA and FKBP5 and growth of LNCaP cells starting from 100 nM with maximum effect observed at 10 μM[1].
UT-34 (0.1-10 μM; 24 hours; LNCaP cells) treatment results in a reduction of AR levels at 1000 nM in LNCaP cells[1].
Treatment of ZR-75-1 cells maintained in serum-containing growth medium with UT-34 results in downregulation of AR protein levels, but not estrogen receptor (ER) or progesterone receptor (PR) levels. Furthermore, in MDA-MB-453 breast cancer cells that express AR and glucocorticoid receptor (GR), UT-34 induces the downregulation of AR, but not GR[1].
UT-34 is an effective degrader of both AR and AR-V7. LNCaP-ARV7 cells are treated for 24 hours in the presence of 0.1 nM R1881 or 10 ng/mL Doxycycline. Doxycycline induces the expression of EDN2, which is inhibited by UT-34, while UT-34 inhibits the expression of R1881-induced FKBP5 gene expression[1].

Cell Viability Assay[1]

Cell Line:LNCaP cells
Concentration:3 μM, 10 μM

Western Blot Analysis[1]

Cell Line:LNCaP cells
Concentration:0.1 μM, 1 μM, 10 μM

体内研究
(In Vivo)

UT-34 (20-40 mg/kg; oral administration; daily; for 14 days; NSG mice) at 20 and 40 mg/kg reduces the seminal vesicle weight by 10%-20% and 50%-60 %, respectively[1].
UT-34 inhibits androgen-dependent tissues such as prostate and seminal vesicles in rats, and the growth of Enzalutamide-resistant castration-resistant prostate cancer (CRPC) xenografts. UT-34 also induces tumor regression in intact immunocompromised rats[1].

Animal Model:Non obese diabetic/severe combined immunodeficiency Gamma (NSG) mice injected with MR49F cells[1]
Dosage:20 mg/kg or 40 mg/kg
Administration:Oral administration; daily; for 14 days
Result:Reduced the seminal vesicle weight.
