Application

PF-06928215 has been used to study its inhibitory effects on cyclic GMP-AMP synthase (cGAS).

Biochem/physiol Actions

PF-06928215 is a high affinity (KD = 200 nM) active site-targeting, substrate-competitive cyclic GMP-AMP synthase (cGAS) inhibitor (IC50 = 4.9 μM; 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.

Trypanosoma cruzi (T. cruzi) is the etiological agent of Chagas cardiomyopathy. In the present study, we investigated the role of extracellular vesicles (Ev) in shaping the macrophage (Mφ) response in progressive Chagas disease (CD). We purified T. cruzi Ev (TcEv)
