SR-717 lithium

• Catalog Number: ACM2375421091
• Product Name: SR-717 lithium
• CAS: 2375421-09-1
• Category: Agonists
• Description: 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.
