WebMar 15, 2016 · Between the two diastereomers of the PS RNA chiral center, the R(p) isomer is 37 times more active than the S(p) one. Among the other divalent metal ions, only Hg(2+) can cleave the substrate due to its extremely high thiophilicity. A catalytic beacon sensor was designed with a detection limit of 1.6 nM Cu(2+) and extremely high selectivity. WebA further investigation of the apparent thiophilicity provided the subject for this study. DBTO was employed as a putative O(3 P)-precursor. However, the effective rate of O(3 P) formation was found to be dependent on reactant concentrations in certain cases. All reactants were found to increase the rate of deoxygenation to some extent, but in ...
