氢溴酸卤夫酮 用途与合成方法
Ki: 18.3±0.5 nM (prolyl-tRNA synthetase)
Halofuginone competitively inhibits prolyl-tRNA synthetase by occupying both the prolineand tRNA-binding pockets of prolyl-tRNA synthetase.
The IC
50
s of Halofuginone (1, 10, 100, 1000, 10000 nM; 48 hours) are 114.6 and 58.9 nM in KYSE70 and A549 cells, respectively.
The IC
50
s of Halofuginone (1, 10, 100, 1000 nM; 24 hours) for NRF2 protein are 22.3 and 37.2 nM in KYSE70 and A549 cells, respectively. The IC
50
of Halofuginone for global protein synthesis is 22.6 and 45.7 nM in KYSE70 and A549 cells, respectively.
Cell Viability Assay
| Cell Line: | KYSE70 cells from human oesophageal cancer harbouring a mutation in the NRF2 gene and A549 cells harbouring the KEAP1 gene mutation |
| Concentration: | 1, 10, 100, 1000, 10000 nM |
| Incubation Time: | 48 hours |
| Result: | The IC 50 s were 114.6 and 58.9 nM in KYSE70 and A549 cells, respectively. |
Western Blot Analysis
| Cell Line: | KYSE70 cells from human oesophageal cancer harbouring a mutation in the NRF2 gene and A549 cells harbouring the KEAP1 gene mutation |
| Concentration: | 1, 10, 100, 1000 nM |
| Incubation Time: | 24 hours |
| Result: | The IC 50 s for NRF2 protein were 22.3 and 37.2 nM in KYSE70 and A549 cells, respectively. |
Halofuginone (0.2, 0.5, 1 or 2.5 mg/kg; injected intraperitoneally every other day for 1 month) attenuates progression of OA in anterior cruciate ligament transection (ACLT) mice. Lower concentration (0.2 or 0.5 mg/kg) has minimal effects on subchondral bone and higher concentration (2.5 mg/kg) induces proteoglycan loss in articular cartilage.
Halofuginone (0.25 mg/kg; intraperitoneally injected; every day; 16 days) decreases NRF2 protein levels in tumors. While the tumor volumes do not change substantially between treatments with the vehicle, Halofuginone (0.25 mg/kg, intraperitoneally injected, every day) or cisplatin alone. Combined treatment with Halofuginone and Cisplatin significantly suppresses the tumor volume compared to treatment with Halofuginone or cisplatin alone.
| Animal Model: | 3-month-old male C57BL/6J (WT) mice |
| Dosage: | 0.2, 0.5, 1 or 2.5 mg/kg |
| Administration: | Injected intraperitoneally every other day for 1 month |
| Result: | Attenuated progression of OA in ACLT mice. |
| Animal Model: | Male nude mice (BALB/C nu/nu mice) (6-8-week) |
| Dosage: | 0.25 mg/kg |
| Administration: | Intraperitoneally injected; every day; 16 days |
| Result: | The combined treatment with Cisplatin significantly suppressed the tumor volume. NRF2 protein levels in tumors were indeed decreased. |
