General description

A cell-permeable benzylidene-thioxo-imidazolidinone compund that directly and reversibly binds to c-Rel to change its conformation and blocks its DNA binding and transcriptional activity (IC50 = 3 µM in EMSA). Shows good selectivity over Oct1 and AP1. Reduces IL-2 expression in activated T cells without affecting their viability. Induces growth arrest in diffuse large B-cell lymphoma (DLBCL) cell line Ly3 (IC50 = 18 uM). Shown to reduce alloactivation in T cells and diminish graft-versus-host disease (GVHD), but does not impair TCR-mediated killing. Improves the survival rate of lethally irradiated BABL/c mice transplanted with T cell depleted bone marrow cells from C57BL/6 mice (~24 mg/kg, i.p, daily).

Please note that the molecular weight for this compound is batch-specific due to variable water content.
