ENPP1 inhibitor 4e is an inhibitor of ectonucleotide pyrophosphatase/phosphodiesterase family member 1 (ENPP1; IC50 = 0.188 µM), an enzyme that degrades the stimulator of interferon genes (STING) activator 2'3'-cGAMP .1 It inhibits ENPP1 in MDA-MB-231 cells, which highly express ENPP1 (IC50 = 0.732 µM). ENPP1 inhibitor 4e is selectively cytotoxic to 4T1 murine metastatic breast cancer cells (IC50 = 2.99 µM) over non-cancerous L-02 and 293T cells at 50 µM. It increases serum levels of IFN-β in mice when administered at a dose of 0.5 mg/kg in combination with cGAMP when compared to mice administered only cGAMP or mice not receiving either compound, indicating that ENPP1 inhibitor 4e reduces the degradation of cGAMP.
