Background:

RU.521 (RU320521) is a potent dsDNA and cGAS inhibitor with an IC50 of 700 nM for dsDNA. RU.521 inhibits cGAS-mediated interferon upregulation and suppresses dsDNA-dependent activation. RU.521 is active and selective in cellular assays of cyclic GMP-AMP synthase-mediated signaling and reduces constitutive expression of interferon in macrophages from a mouse model of Aicardi-GoutiÈres syndrome (AGS)[1]. IC50: 700 nM (dsDNA)[1]
