Description: I-BET-726, also known as GSK1324726A, is a potent and selective inhibitor of BET family proteins. Oral administration of I-BET726 to mouse xenograft models of human neuroblastoma results in tumor growth inhibition and down-regulation MYCN and BCL2 expression, suggesting a potential role for these genes in tumor growth.
