Unveiling the agonistic properties of Preyssler-type Polyoxotungstates on purin...
Poejo, Joana; Gumerova, Nadiia I.; Rompel, Annette; Mata, Ana M.; Aureliano, Manuel; Gutierrez-Merino, CarlosThe Preyssler-type polyoxotungstate ({P5W30}) belongs to the family of polyanionic metal-oxides formed by group V and VI metal ions, such as V, Mo and W, commonly known as polyoxometalates (POMs). POMs have demonstrated inhibitory effect on a significant number of ATP-binding proteins in vitro. Purinergic P2 receptors, widely expressed in eukaryotic cells, contain extracellularly oriented ATP-binding sites and ...
Inhibition of SERCA and PMCA Ca2+-ATPase activities by polyoxotungstates
Aureliano, Manuel; Fraqueza, Gil; Berrocal, Maria; Cordoba-Granados, Juan J.; Gumerova, Nadiia I.; Rompel, Annette; Gutierrez-Merino, CarlosPlasma membrane calcium ATPases (PMCA) and sarco(endo) reticulum calcium ATPases (SERCA) are key proteins in the maintenance of calcium homeostasis. Herein, we compare for the first time the inhibition of SERCA and PMCA calcium pumps by several polyoxotungstates (POTs), namely by Wells-Dawson phospho-tungstate anions [P2W18O62]6-(intact, {P2W18}), [P2W17O61]10-(monolacunary, {P2W17}), [P2W15O56]12-(trilacunary,...
Gold compounds inhibit the Ca2+-ATPase activity of brain PMCA and human neurobl...
Berrocal, Maria; Cordoba-Granados, Juan J.; Carabineiro, Sónia A. C.; Gutierrez-Merino, Carlos; Aureliano, Manuel; Mata, Ana M.Plasma membrane calcium ATPases (PMCA) are key proteins in the maintenance of calcium (Ca<sup>2+</sup>) homeostasis. Dysregulation of PMCA function is associated with several human pathologies, including neurodegenerative diseases, and, therefore, these proteins are potential drug targets to counteract those diseases. Gold compounds, namely of Au(I), are well-known for their therapeutic use in rheumatoid arthri...
