Biochem/physiol Actions

PF-06928215 is a high affinity (KD of the (1R,2S) enantiomer = 200 nM) active site-targeting, substrate-competitive cyclic GMP-AMP synthase (cGAS) inhibitor (IC50 = 4.9 μM using the (1R,2S) enantiomer; in the presence of 1 mM ATP, 0.3 mM GTP, 100 nM 45-bp interferon-stimulatory dsDNA (ISD)). PF-06928215 displays no inhibitory potency against dsDNA-induced IFN-β expression in cellular cGAS assays, most likely due to limited cell-permeability and/or high levels of cellular ATP and GTP in the reporter cells employed. Note: this product contains the two cis-enantiomers (1R,2S) and (1S,2R).
