Biological Activity

GSK1324726A (I-BET726) is a highly selective inhibitor of BET family proteins with IC50 of 41 nM, 31 nM, and 22 nM for BRD2, BRD3, and BRD4, respectively. GSK1324726A inhibits cell growth and induces cytotoxicity in neuroblastoma cell lines. GSK1324726A also modulates expression of genes involved in apoptosis, signaling, and MYC-family pathways, including the direct suppression of BCL2 and MYCN.

In vivo, in the mouse SK–N-AS and CHP-212 models, GSK1324726A (15 mg/kg p.o.) results in tumor growth inhibition and down-regulation MYCN and BCL2 expression. [1] In a mouse septic shock model, GSK1324726A (10 mg/kg i.v.) shows potent anti-inflammatory effects, and prevents death of diseased animals.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
