nebularine

Nebularine (9-(beta-D-Ribofuranosyl)-9H-purine) is a purine nucleoside analog with a broad spectrum of antitumor activity, targeting inert lymphoid malignancies and inducing apoptosis.The anticancer mechanism of Nebularine is dependent on the inhibition of DNA synthesis.

8-Azanebularine, a chemical compound substituting hydrogen for the C6 amino group, effectively inhibits the ADAR2 reaction at elevated concentrations (IC50=15 mM), and exhibits high-affinity binding (KD=2 nM) when incorporated into an RNA structure recognized by human ADAR2. This characteristic makes 8-Azanebularine valuable for researching the ADAR-catalyzed RNA-editing reaction.

DMTr-2'-O-TBDMS-8-azanebularine-3'-CE-phosphoramidite is a monomeric material utilized in the synthesis of nucleic acids.

Purine riboside-5'-O-triphosphate sodium is an active metabolite of Nebularine and acts as an inhibitor of DNA primase ATP and GTP polymerization activities, with IC50 values of 35 µM and 28 µM, respectively. It also inhibits calmodulin-dependent protein kinase II (CaMKII), with a Ki value of 590 µM.
