Enpp-1-IN-27 is a selective ENPP1 inhibitor with an IC50 of 14.68 nM, exhibiting approximately 410-fold selectivity over ENPP2 and roughly 10-fold selectivity over ENPP3. This compound stabilizes cGAMP levels and activates the STING pathway, leading to cytokine release and an enhanced innate immune response. In addition, Enpp-1-IN-27 activates ISRE and boosts cGAMP-mediated immune responses, demonstrating significant antitumor effects in 4T1 and CT26 syngeneic mouse models. It is applicable to breast cancer and colon cancer research.
