NTPDase-IN-2 (compound 5g) selectively inhibits NTPDase-2 and NTPDase-8 with IC50 values of 0.04 µM and 2.27 µM, respectively, and exhibits non-competitive inhibition toward h-NTPDase-1 and h-NTPDase-2, with a Km of 74 µM for h-NTPDase-2. This compound is applicable in researching cancer, immunological disorders, and bacterial infections [1].

h-NTPDase-IN-4 is a pan-inhibitor of NTPDase, which can inhibit h-NTPDase1, 1h-NTPDase2, h-NTPDase3, h-NTPDase8. The IC50 values were 3.58 μM, 10.21 μM, 0.13 μM and 13.57 μM, respectively.

h-NTPDase-IN-1 (Compound 3i) is an inhibitor of human NTPDase with IC50 values of 2.88 μM for h-NTPDase1 and 0.72 μM for h-NTPDase3, indicating potential utility for thrombosis, inflammation, diabetes, and cancer research [1].

h-NTPDase-IN-5 (compound 3b) serves as a pan-inhibitor of NTPDase, exhibiting inhibitory concentration 50 (IC50) values of 1.10 μM [h-NTPDase1], 44.73 μM [h-NTPDase2], 26.14 μM [h-NTPDase3], and 0.32 μM [h-NTPDase8].

h-NTPDase8-IN-1 is a specific aminosulfonylbenzamide inhibitor of h-NTPDases8 (IC 50 = 0.28 ± 0.07 μM). h-NTPDase8-IN-1 can be used to study diseases brought about by aberrant h -NTPDase expression.

TcNTPDase1-IN-1 (compound 16) serves as an inhibitor of nucleoside triphosphate diphosphohydrolase 1 (TcNTPDase1) from Trypanosoma cruzi in vitro. This compound is applicable in research related to antibacterial, antitoxic, and antitumor activities.

Sodium metatungstate (Sodium polyoxotungstate) is a potent inhibitor of ecto-nucleoside triphosphate diphosphohydrolase (NTPDase), with Ki values of 2.58 μM for NTPDase 1, 3.26 μM for NTPDase 3, and 28.8 μM for NTPDase 2.

Sodium metatungstate (Sodium polyoxotungstate; POM-1) hydrate is an inhibitor of NTPDase, with Ki values for NTPDase1 (CD39), NTPDase 3, and NTPDase 2 being 2.58 μM, 3.26 μM, and 28.8 μM, respectively. It exhibits anti-inflammatory and anticancer properties and inhibits ATP hydrolysis while also blocking central synaptic transmission.
