Product Introduction
Bioactivity


英文名: Finasteride acetate

描述: Finasteride (MK-906) acetate 是一种高效的5α-还原酶 (5α-reductase) 竞争性抑制剂，其对 II 型 5α-还原酶的IC50值仅为 4.2 nM，其对该型酶的亲和力是对 I 型酶亲和力的约100倍。因此，Finasteride acetate 主要在良性前列腺增生症 (BPH) 和雄激素性脱发研究领域中应用。

体外活性: Finasteride (10 μM; 6-24 h) induces the expression of HO-1 and Nrf2 proteins in PC-3 cells [2]. Finasteride can reduce the conversion of [ 3 H]testosterone (T) to [ 3 H]dihydrotestosterone (DHT) in P. crustosum [1]. Cell Viability Assay [2] Cell Line: PC-3, DU-145, and LNCaP cells Concentration: 10 μM Incubation Time: 6, 12, 24 h Result: Increased the expression of HO-1 protein in a time-dependent manner in PC-3 cells. Induced the expression of Nrf2 protein in DU-145 and PC-3 cells, but not in LNCaP cells.

体内活性: Finasteride (0.1-0.5 mg/kg; p.o. once daily for 16 weeks) reduces prostatic size in dogs with BPH while not adversely affecting semen quality or serum testosterone concentration [3]. Animal Model: Male dogs with spontaneous BPH (2.7-11 years old; 10.3-49 kg) [3] Dosage: 0.1-0.5 mg/kg Administration: P.o. once daily for 16 weeks Result: Decreased prostatic diameter (20%), prostatic volume (43%), and serum DHT concentration (58%). Decreased semen volume but did not adversely effect on semen quality or serum testosterone concentration. No adverse effects on dogs.

存储条件: Powder: -20°C for 3 years | In solvent: -80°C for 1 year
