PSB-12379

PSB-12379 is an inhibitor of ecto-5'-nucleotidase (CD73, Kis = 2.21 and 9.03 nM for the recombinant human and rat enzyme, respectively). It is selective for CD73 over human nucleoside triphosphate diphosphohydrolase 1 (NTPDase 1), -2, and -3, ectonucleotide pyrophosphatase/phosphodiesterase family member 1 (ENPP1), -2, and -3 (Kis = >10,000 nM for all), as well as the purinergic P2Y1 and P2Y12 receptors at 10 µM. PSB-12379 inhibits CD73 in isolated human serum with a Ki value of 18.8 nM.Formal Name: N-(phenylmethyl)-adenosine, 5'-[hydrogen P-(phosphonomethyl)phosphonate]. CAS Number: 1802226-78-3.
