  • Description

Halofuginone(cas 55837-20-2) inhibits the development of T helper 17 cells, immune cells that play an important role in autoimmune disease, but it does not affect other kinds of T cells which are involved in normal immune function. Halofuginone therefore has potential for the treatment of autoimmune disorders.
Halofuginone is also an inhibitor of collagen type I gene expression and as a consequence it may inhibit tumor cell growth. Halofuginone exerts its effects by acting as a high affinity inhibitor of the enzyme glutamyl-prolyl tRNA synthetase. Inhibition of prolyl tRNA charging leads to the accumulation of uncharged prolyl tRNAs, which serve as a signal to initiate the amino acid starvation response, which in turn exerts anti-inflammatory and anti-fibrotic effects.

In vitro: The addition of halofuginone can significantly inhibit the migratory and invasive trend induced by irradiation, and the TGF-β pathway was also inhibited. In the study, we observed the strong inhibitory activity of halofuginone on HepG2 cell growth and the cell cycle and apoptosis assays showed that halofuginone arrested the cell cycle and inhibited the induction. And we found that halofuginone inhibits tumor cell cycle possibly by up-regulating p15 and p21 of expression. Then, we found that the proportion of cleaved PARP, caspase-3, 8 and 9 in HepG2 cells increased after halofuginone treatment. And the results showed that halofuginone down-regulated Mcl-1 and c-IAP1 expression. Finally, our results showed halofuginone regulated the activities of JNK and MEK/ERK signaling pathways in hepatocellular carcinoma cells.
In vivo: In animal xenograft model, the addition of halofuginone to irradiation inhibited the growth of subcutaneously implanted xenografts, reduced hepatic and pulmonary metastases, and improved survival of the mice. C57BL/6 recipient mice received an orthotopic left lung transplant, and Lung transplant recipients received daily intraperitoneal injections of 2.5 μg halofuginone or vehicle alone. Lung grafts were assessed on Days 7, 14, and 28 post-transplant. Compared with control mice, on Day 28 post-transplant, lung grafts of mice treated with halofuginone showed a significant reduction in the percentage of obliterated airways (6.8 ± 4.7% vs 52.5 ± 13.8%, p < 0.01), as well as significantly reduced parenchymal fibrosis (5.5 ± 2.3% vs 35.9 ± 10.9%, p < 0.05).
