Description:

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

IT-901 is a c-Rel Inhibitor That Mediates Anticancer Properties in Hematologic Malignancies by Blocking NF-κB-Controlled Oxidative Stress Responses. IT-901 potently inhibits the NF-κB subunit c-Rel. IT-901 suppressed graft-versus-host disease while preserving graft-versus-lymphoma activity during allogeneic transplantation. Further preclinical assessment of IT-901 for the treatment of human B-cell lymphoma revealed antitumor properties in vitro and in vivo without restriction to NF-κB-dependent lymphoma. IT-901 did not elicit increased levels of reactive oxygen species in normal leukocytes, illustrating its cancer selective properties. IT-901 is a novel therapeutic agent to treat human lymphoid tumors and ameliorate graft-versus-host disease.

Product Data
Biological target:
IT-901 is an orally active and potent NF-κB subunit c-Rel inhibitor with an IC50 of 0.1 µM, 3 μM for NF-κB DNA binding and c-Rel DNA binding, respectively.
In vitro activity:
c-Rel inhibitor IT901 at a concentration higher than 5 μM caused toxicity to BV2 cells and IT901 at 2.5 μM could inhibit c-Rel activity in LPS-treated BV2 cells (Supplementary Fig. S5). This study found BV2 cells treated with IT901 produced more NO compared to DMSO-treated cells after LPS stimulation (Fig. 5H).

In vivo activity:
Moreover, flow cytometry (Figure 7C) and immunohistochemistry (IHC) analyses, using an anti-human CD20 antibody (Figure 7D and Online Supplementary Figure S4A), indicated that IT-901 treatment significantly reduced the number of Mec-1 cells in liver, spleen and bone marrow (BM). In line with the specificity of action of IT-901, a significant decrease in total expression and nuclear localization of the p65 subunit was apparent in IT-901-treated mice (Figure 7D and Online Supplementary Figure S4B).
