Purine riboside-5'-O-triphosphate (sodium)
Purine riboside-5'-O-triphosphate sodium, an active metabolite of Nebularine , acts as an inhibitor of DNA primase ATP and GTP polymerization activities, with IC50 values of 35 µM and 28 µM for the human enzyme, respectively. Purine riboside-5'-O-triphosphate sodium inhibits calmodulin-dependent protein kinase II (CaMKII) with a Ki value of 590 µM[1][2][3].
