NTPDase-IN-2 (compound 5g) is a selective NTPDase inhibitor with IC50s of 0.04 and 2.27 μM for h-NTPDase-2/-8, respectively. NTPDase-IN-2 non-competitively inhibits h-NTPDase-1/-2 with a Km of 74 μM for h-NTPDase-2. NTPDase-IN-2 can be used in studies of cancer, immunologic disorders as well as bacterial infections[1].

h-NTPDase-2: 0.04 μM (IC₅₀); h-NTPDase-8: 2.27 μM (IC₅₀); h-NTPDase-1: ＞100 μM (IC₅₀); h-NTPDase-3: ＞100 μM (IC₅₀)
