Background |
Halofuginone is a competitive prolyl-tRNA synthetase inhibitor. Halofuginone has anti-malarial, anti-inflammatory, anti-cancer and anti-fibrosis activities. |
Biological Activity |
Halofuginone 是 Febrifugine 的一种低毒性衍生物,可从 Dichroa febrifuga 中分离出来[1]。Halofuginone 是一种 ATP 竞争性的脯氨酰-tRNA 合成酶 (prolyl-tRNA synthetase) 抑制剂,Ki 为 18.3 nM[2]。Halofuginone 通过抑制 TGF-β 活性可减轻骨关节炎[3]。 |
In Vitro |
Halofuginone通过占据脯氨酰-tRNA合成酶的脯氨酸和tRNA结合口袋竞争性地抑制脯氨酰-tRNA合成酶[1]。在KYSE70和A549细胞中,Halofuginone的IC50为114.6和58.9nM。在KYSE70和A549细胞中,Halofuginone对NRF2的IC50分别为22.3和37.2nM。在KYSE70和A549细胞中,Halofuginone对全球蛋白质合成的IC50分别为22.6和45.7 nM [1]。在KYSE70和A549细胞系中,在Halofuginone存在下NRF2蛋白的量显著降低。在将Halofuginone应用于KYSE70和A549细胞后,NRF2 mRNA水平没有降低,而是增加,表明Halofuginone在转录后水平起降低NRF2蛋白表达的作用。时程研究表明,Halofuginone在治疗12小时内降低了KYSE70和A549细胞中NRF2蛋白的表达[1]。 |
In Vivo |
Halofuginone减弱前交叉韧带横断(ACLT)小鼠的OA进展。使用多次浓度的HF(0.2,0.5,1或2.5mg/kg)在手术后每隔一天注射1个月来确定最佳剂量(1mg/kg体重)。较低浓度(0.2或0.5 mg/kg)对软骨下骨的影响最小,较高浓度(2.5 mg/kg)可诱导关节软骨中蛋白多糖的丢失[3]。 Halofuginone(0.25mg/kg,腹膜内)降低肿瘤中的NRF2蛋白水平。虽然与载体治疗之间肿瘤体积没有显著变化,但是单独使用卤夫酮(0.25 mg/kg,腹膜内注射,每天)或单独使用顺铂,与单独使用Halofuginone或顺铂治疗相比,Halofuginone和顺铂联合治疗显著抑制了肿瘤体积[1]。 |
