Enpp-1-IN-32
Enpp-1-IN-32 is an orally active, selective ENPP-1 inhibitor with an IC50 of 9.5 nM. Enpp-1-IN-32 shows selectivity over ENPP2/ENPP3. Enpp-1-IN-32 blocks cGAMP hydrolysis, and activates the STING pathway. Enpp-1-IN-32 exhibits antitumor effects in syngeneic mouse models. Enpp-1-IN-32 can be used for the research of triple-negative breast carcinoma.

Biological Activity
Enpp-1-IN-32 (compound A25) shows negligible activity against recombinant human ENPP2 and weak activity against recombinant human ENPP3 (IC50 > 1000 nM)[1].
Enpp-1-IN-32 (3 h) potently inhibits cellular ENPP1 activity in MDA-MB-231 cells with an IC50 of 262.3 nM[1].
Enpp-1-IN-32 (12.5-50 μM; 48 h) shows no cytotoxicity toward MDA-MB-231, 4T1, HEK-293T, or THP-1 cells[1].
Enpp-1-IN-32 (25 μM; 1-24 h) effectively enhances cGAMP-mediated STING pathway activation in THP-1 cells, increasing downstream gene expression, IFN-β secretion, and phosphorylation of STING, TBK1, and IRF3[1].
