npp 3

NPP3-IN-1 (Compound 3e) is an inhibitor of phosphodiesterase/pyrophosphatase-3 (NPP3), exhibiting IC50 values of 0.24 μM for NPP3 and 1.37 μM for NPP1.

Enpp/Carbonic anhydrase-IN-1 (compound 1e) is a potent inhibitor of Enpp and carbonic anhydrase, exhibiting IC50s of 1.36, 1.35, 3.00, 0.88, and 1.02 µM for NPP1, NPP2, NPP3, CA-II, and CA-IX respectively. Enpp/Carbonic anhydrase-IN-1 also demonstrates selective antiproliferative activity for cancer cells.

Enpp/Carbonic anhydrase-IN-2 is a potent dual inhibitor of Enpp and carbonic anhydrase, inhibiting NPP1, NPP2, NPP3, CA-IX, CA-XII, with IC50 values of 1.13, 1.07, 0.74, 0.33, 0.68, respectively.Enpp/Carbonic anhydrase-IN-2 induced apoptosis.Enpp/Carbonic anhydrase-IN-2 has antiproliferative activity against cancer cells and low cytotoxicity against normal cells.

ENPP3 Inhibitor 1 is a selective inhibitor of ENPP3, exhibiting an IC50 value of 0.15 µM, compared to an IC50 of 41.4 µM for ENPP1. It demonstrates antitumor effects against breast and cervical cancers.
