ABSTRACT
Polyoxotungstates were identified as potent inhibitors of NTPDases1, 2, and 3. The most potent compound was K(6)H(2)[TiW(11)CoO(40)], exhibiting K(i) values of 0.140 microM (NTPDase1), 0.910 microM (NTPDase2), and 0.563 microM (NTPDase3). One of the compounds, (NH(4))(18)[NaSb(9)W(21)O(86)], was selective for NTPDases2 and 3 versus NTPDase1. NTPDase inhibition might contribute to the described biological effects of polyoxometalates, including their anti-cancer activity.
