NPP1-IN-1 is a highly potent inhibitor of NPP enzymes, effectively inhibiting NPP1 with an IC 50 value of 0.15 μM and NPP3 with an IC 50 value of 40 μM [1].
ARL 67156 is a weak competitive inhibitor of NTPDase1 (CD39), NTPDase3 and NPP1, with Kis of 11, 18 and 12 μM, respectively[1]. ARL67156 trisodium salt is an inhibitor of ecto-ATPase.
Enpp-1-IN-11 (compound 23) is a highly potent inhibitor of Ecto-nucleotide pyrophosphatase phosphodiesterases 1 (ENPP1), with a Ki value of 45 nM. It demonstrates excellent stability in human and mouse plasma and exhibits low clearance in both human and mouse liver microsomes. Enpp-1-IN-11 holds promise for anticancer research [1].
Enpp-1-IN-9, a powerful inhibitor of ectonucleotide pyrophosphatase-phosphodiesterase 1 (ENPP1), exhibits wide substrate specificity, capable of cleaving various bonds such as phosphodiester bonds of nucleotides and nucleotide sugars, as well as pyrophosphate bonds of nucleotides and nucleotide sugars. Its potential application lies in the fields of cancer and infectious disease research[1].
