SR-717 is an agonist of stimulator of interferon genes STING for treating cancer. SR-717 demonstrates broad interspecies and interallelic specificity. SR-717 functions as a direct cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) mimetic that induces the same "closed" conformation of STING. SR-717 displayed antitumor activity; promoted the activation of CD8+ T, natural killer, and dendritic cells in relevant tissues; and facilitated antigen cross-priming. SR-717 also induced the expression of clinically relevant targets, including programmed cell death 1 ligand 1 (PD-L1), in a STING-dependent manner.

How to use

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. SR-717 (3.8 μM) induces the expression of PD-L1 in THP1 cells and in primary human peripheral blood mononuclear cells in a STING-dependent manner.

In Vivo:

SR-717 (30 mg/kg intraperitoneal once-per-day for 1 week) shows antitumor activities in WT or Stinggt/gt mice. 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.
