cGAS inhibition by RU.365 and its chemical active analogs. a In vitro concentration response curves for RU.365 and the most potent analog synthesized in-house, RU.521, in the presence of dsDNA, ATP and GTP as measured by RF-MS. The IC50 values for RU.365, RU.521 and less potent analogs are listed in Supplementary Table 4. Values are averages of triplicate determinations with SD indicated. b Isothermal titration calorimetry-binding curves for RU.521 titrated into cGAS/dsDNA complex
