Immunology/Inflammation

SR-717 is a non-nucleotide STING agonist with EC₅₀s of 2.1 uM and 2.2 uM in ISG-THP1 (WT) and ISG-THP1 cGAS KO (cGAS KO) cell lines, respectively. SR-717 is a stable cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) mimetic. Antitumor activity^[1]. In Vitro: SR-717 activates STING by inducing the same closed conformation, which thereby provides an avenue to explore this class of systemic STING agonist in diverse contexts, including antitumor immunity^[1].
SR-717 (3.8 uM) induces the expression of PD-L1 in THP1 cells and in primary human peripheral blood mononuclear cells in a STING-dependent manner^[1]. In Vivo: SR-717 (30 mg/kg intraperitoneal once-per-day for 1 week) shows antitumor activities in WT or Sting^gt/gt mice^[1].
SR-717 (30 mg/kg intraperitoneally for 7 days) displays antitumor activity; promots the activation of CD8⁺ T, natural killer, and dendritic cells in relevant tissues; and facilitates antigen cross-priming^[1].
