生物活性

UT-143 is an orally active, selective irreversible covalent antagonist of androgen receptor (AR). UT-143 inhibits the proliferation of AR-positive prostate cancer cells, reduces the weight of androgen target tissues in rats, and suppresses the growth of AR-positive xenograft tumors. UT-143 can be used for the research of prostate cancer[1].

体外研究
(In Vitro)

UT-143 (10 µM; 16 h) 可显著降低 22RV1 前列腺癌细胞中全基因组染色质的可及性,将可及区域数量从 36141 个减少至 10302 个[1]
UT-143 抑制雄激素受体转录激活,IC50 值为 0.15 μM[1]

体内研究
(In Vivo)

UT-143 (20 mg/kg;口服;每日一次;连续 13 天) 可强效抑制正常雄性 Sprague-Dawley 大鼠的雄激素依赖性前列腺及精囊生长,且不会改变大鼠的体重或非靶器官重量[1]
UT-143 (60 mg/kg;口服;每日一次;连续 18 天) 可强效抑制雄性免疫健全 NSG 小鼠体内 AR 阳性 LNCaP-AR 前列腺癌异种移植瘤的生长,肿瘤生长抑制率超过 95%[1]

Reduced seminal vesicle weight to ~200 mg (vehicle control ~400 mg, P<0.01).
Had no effect on body weight, lean mass, fat mass, or the weights of the heart, kidney, spleen, and thymus.
Animal Model: NSG (male)[1]
Dosage: 60 mg/kg
Administration: p.o.; daily; 18 days
Result: Achieved greater than 95% tumor growth inhibition, with tumor volume showing a net decrease from baseline over the treatment period.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
