Biological Activity

MS417 (also known as GTPL7512) is a potent and selective BRD4 inhibitor, which binds to BRD4-BD1 and BRD4-BD2 with IC50s of 30 and 46 nM, respectively. MS417 effectively blocks BRD4 binding to NF-κB, almost completely suppresses TNFα-induced NF-κB transcription activation in human embryonic kidney 293T cells at 1 μM and also reduces NF-κB p65 acetylation in the HIV-infected RTECs. MS417 (1 μM) modulation of gene transcription in HIV-infected human primary renal tubular epithelial cells. 

In vivo, MS417 (0.08 mg/kg) markedly improves renal function, reduces proteinuria and decreases glomerulosclerosis, tubular injury, and infiltration of inflammatory cells in the kidney of Tg26 mice.

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.
