Thermodynamic properties of autunite, uranyl hydrogen phosphate, and uranyl orthophosphate from solubility and calorimetric measurements.

29 Sep 2009 In this study, we use solubility and drop-solution calorimetry measurements to determine the thermodynamic properties of the uranyl phosphate phases autunite, uranyl hydrogen phosphate, and uranyl orthophosphate. Conducting the solubility ... Read more...

Intramolecular cooperativity in the reaction of diacyl phosphates with serine beta-lactamases.

6 Sep 2009 Asymmetric diaroyl phosphates (ArCOOPO(2)(-)OCOAr', where Ar = Ph, Ar' = 4-biphenyl, 2-benzothiophenyl and 2-benzofuranyl) have been prepared, evaluated as serine (classes A, C, and D) beta-lactamase inhibitors, and compared with respect to the ... Read more...

Inhibition of class A and C beta-lactamases by diaroyl phosphates.

6 Sep 2009 A series of diaroyl phosphates was employed to assess the general reactivity of this class of molecule against classical class A and class C beta-lactamases. The compounds were found, in general, to be inhibitory substrates of both classes of ... Read more...
