KI-TOX-A3

KI-TOX-A3 is a selective protein-protein interaction (PPI) inhibitor targeting the TOX protein, with an IC50 value of 0.51 ?M for the TOX-KAT7 interaction. It promotes proteasomal degradation of TOX, restores KAT7-mediated H3K14 acetylation, reverses CD8+ T cell exhaustion, and inhibits proliferation of T-cell acute lymphoblastic leukemia (T-ALL) cells. KI-TOX-A3 holds potential for research in hematological malignancies, including T-ALL.
