Enpp-1-IN-27

Enpp-1-IN-27 is a selective ENPP1 inhibitor with an IC50 of 14.68 nM, exhibiting approximately 410-fold selectivity against ENPP2 and 10-fold selectivity against ENPP3. Enpp-1-IN-27 stabilizes cGAMP levels and activates the STING pathway, promoting cytokine release and enhancing innate immune responses. Enpp-1-IN-27 induces ISRE activation and amplified cGAMP-mediated immune responses and shows the desired antitumor efficacy in the 4T1 and CT26 syngeneic mouse models. Enpp-1-IN-27 can used for the studies of breast cancer and colon cancer[1].
