Description

Biochem/physiol Actions

G150 is a substrate site-targeting, potent and selective human cyclic GMP-AMP synthase (cGAS) inhibitor (IC50 = 10.2 nM; 100 nM h-cGAS, 0.1 mM ATP & GTP, 25 nM 100-bp dsDNA) with no murine cGAS potency (IC50 >25 μM) and low cytotoxicity (THP1 LD50 = 53 μM). G150 selectively inhibits dsDNA-induced IFNB1/CXCL10 transcription in THP1 (IC50 = 1.96/7.57 μM) & primary human macrophages (IC50 = 0.62/0.87 μM) without affecting adenylyl cyclase activity, direct STING activation by cGAMP, or immune responses induced by hpRNA (RIG-I pathway), poly(I:C) (OAS/RNase L pathway), LPS (TLR4 pathway).

Substrate site-targeting, non-cytotoxic, potent and selective human cyclic GMP-AMP synthase (cGAS) inhibitor against cellular STING signaling.
