ENPP3 inhibitor is an inhibitor of ectonucleotide pyrophosphatase/phosphodiesterase family member 3 (ENPP3; Ki = 53.7 nM).1 It is selective for ENPP3 over ENPP1, ENPP2, tissue-nonspecific alkaline phosphatase (TNAP), ecto-5′-nucleotidase (CD73), nucleoside triphosphate diphosphohydrolase 1 (NTPDase 1), NTPDase 2, and NTPDase 3. ENPP3 inhibitor also inhibits carbonic anhydrase II (CAII) and CAIX (Kis = 74.7 and 20.3 nM, respectively).
