Description:

WARNING: This product is for research use only, not for human or veterinary use.

Homoharringtonine, or Omacetaxine mepesuccinate, is a pharmaceutical drug substance that is indicated for treatment of chronic myeloid leukemia (CML). It is a natural product first discovered in Cephalotaxus harringtonia, now manufactured by hemi-synthesis. It was approved by the US FDA in October 2012 for the treatment of adult patients with CML with resistance and/or intolerance to two or more tyrosine kinase inhibitors (TKIs).

Biological target:
Homoharringtonine (Omacetaxine mepesuccinate; HHT) is a cytotoxic alkaloid with antitumor properties which acts by inhibiting translation elongation.
In vitro activity:
TGF-β stimulation could induce EMT and increase the migration of tumor cells. The study next investigated the effect of HHT (Homoharringtonine) on HCC (hepatocellular carcinoma) cells migration after TGF-β stimulation by transwell migration assay and wound healing assay. As shown in Fig. 4a, c, although the higher number of migration cells was observed in the TGF-β induced HepG2 cells, as compared to controls, the addition of HHT reduced the migrated cells. Importantly, concurrent treatment with HHT and NVP-BHG712 (a small molecule EphB4 kinase-specific inhibitor) had a greater restraint effect on the migration of TGF-β induced HepG2 cells. Wound healing assay showed similar results that HHT could delay the closure of wound gaps in TGF-β induced HepG2 cells, whereas the addition of EphB4 siRNA impaired such effect (Fig. 4b, d). These results indicated that TGF-β induced the migration ability in HepG2 cells, which could be abrogated by EphB4 suppression of HHT.

In vivo activity:
The results of collagen density in the HHT (Homoharringtonine)-treated groups coincided with hematoxylin and eosin staining. Furthermore, HPC analysis was performed to reflect the amount of collagen in intraarticular fibrosis scar tissue. As shown in Fig. Fig.2d, following treatment of HHT, the HPCs of intraarticular scar tissue were significantly decreased compared to that of the control group. The observed results indicated that HHT could inhibit fibroblast proliferation and collagen production, reducing intraarticular fibrosis after knee surgery in rabbits.
