Halofuginone (Synonyms: RU-19110)

Cat. No.: HY-N1584 Purity: 98.32%
Handling Instructions

Halofuginone (RU-19110) is a less-toxic form of Febrifugine, which is isolated from the plant Dichroa febrifuga. Halofuginone inhibits prolyl-tRNA synthetase in an ATP-dependent manner with a Ki of 18.3 nM. Halofuginone attenuates osteoarthritis (OA) by inhibition of TGF-β activity.

Description

Halofuginone (RU-19110) is a less-toxic form of Febrifugine, which is isolated from the plant Dichroa febrifuga[1]. Halofuginone inhibits prolyl-tRNA synthetase in an ATP-dependent manner with a Ki of 18.3 nM[2]. Halofuginone attenuates osteoarthritis (OA) by inhibition of TGF-β activity[3].

IC50 & Target

Ki: 18.3±0.5 nM (prolyl-tRNA synthetase)[2]

In Vitro

Halofuginone competitively inhibits prolyl-tRNA synthetase by occupying both the prolineand tRNA-binding pockets of prolyl-tRNA synthetase[1].
The IC50s of Halofuginone (1, 10, 100, 1000, 10000 nM; 48 hours) are 114.6 and 58.9 nM in KYSE70 and A549 cells, respectively.
The IC50s 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 IC50 of Halofuginone for global protein synthesis is 22.6 and 45.7 nM in KYSE70 and A549 cells, respectively[1].

Cell Viability Assay[1]

Cell Line: KYSE70 cells from human oesophageal cancer harbouring a mutation in the NRF2 gene and A549 cells harbouring theKEAP1 gene mutation
Concentration: 1, 10, 100, 1000, 10000 nM
Incubation Time: 48 hours
Result: The IC50s were 114.6 and 58.9 nM in KYSE70 and A549 cells, respectively.

Western Blot Analysis[1]

Cell Line: KYSE70 cells from human oesophageal cancer harbouring a mutation in the NRF2 gene and A549 cells harbouring theKEAP1 gene mutation.
Concentration: 1, 10, 100, 1000 nM
Incubation Time: 24 hours
Result: The IC50s for NRF2 protein were 22.3 and 37.2 nM in KYSE70 and A549 cells, respectively.
In Vivo

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[3].
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[1].

Animal Model: 3-month-old male C57BL/6J (WT) mice[3]
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)[1]
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.
