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. IT-901, a bioactive naphthalenethiobarbiturate derivative, has the potential for human lymphoid tumors and ameliorate graft-versus-host disease (GVHD).

In Vitro

IT-901 (1, 3, 5 μM; for 24 hours) results in decreased proliferation of viable ABC and GCB DLBCL cells^[1].
IT-901 (3 μM; for 24 hours) decreases cell viability in a dose-dependent fashion, at least 60 percent of cells were still viable after 48 hours of IT-901 treatment (4μM) in all tested cell lines except HBL1^[1].
IT-901 (1, 5, 10 μM; for 6 hours) documents Diminished expression of p65 and p50 in nuclear and cytosolic fractions and also decreases the expression of the inhibitory subunit IκBα both in the phosphorylated and non-phosphorylated forms in primary CLL cells and cell lines^[2].
The IC₅₀ of IT-901/GDM-12 is 2.9 μM for c-Rel whereas IL-2 secretion is successfully blocked at 5 μM^[1].
The concentrations of IT-901 above 10 μM become increasingly toxic and may lead to apoptosis of healthy cells^[1].
IT-901 inhibits cell growth of both activated B-like (ABC) and germinal center B-like (GCB) cell lines with the IC₅₀ values between 3μM to 4μM^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
