Biological Activity

STING inhibitor 18 is a potent, orthosteric STING inhibitor / antagonist with IC50 of 68 nM in HAQ STING cGAMP displacement assay.
STING inhibitor 18 displace cGAMP and stabilize the “open” conformation of STING, a key assumption is that stabilizing the “open” conformation will prevent all STING signaling.
STING inhibitor 18 exhibits good oral exposure, slow binding kinetics, and functional inhibition of STING-mediated cytokine release.
