RIG012 is a potent RIG-I inhibitor with an IC50 of 0.71 μM (measured by NADH-coupled ATPase), and it inhibits the expression of IFN-β and ISG hRsad2.

RIG-I:0.71 μM

RIG012 (1, 1.25, 1.5, 2, 2.5, 3, 4 μM) has potent dose-dependent inhibition of RIG-I signaling in HEK293T cells co-transfected with expression plasmids and reporter plasmids.[1]
RIG012 (1.25, 2.25, 4.5, 9, 18 μM) has potent dose-dependent inhibition of IFN-β and ISG hRsad2 expression in A549 cells.[1]
RIG012 contains a strong chromophore that absorbs in the visible range (λmax of 470 nm). Upon binding to RIG-I, the 470 nm absorption band of RIG012 undergoes a significant hyperchromic shift toward higher intensity values.[1]
