Biological Activity

H-151 is a highly potent, selective and covalent antagonist of STING, reduces TBK1 phosphorylation and suppresses human STING palmitoylation. H-151 (0.02-2 μM) reduces IFNβ luciferase reporter measurements of HEK293T cells. H-151 (0.5 μM; 2 h) inhibits the phosphorylation of TBK1 in THP-1 cells.

Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

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.
