highly potent mutant kinase-specific inhibitorsbased on a pyrazolopyrimidine scaffold. Here, we asked if the selectivity of the resulting pyrazolopyrimidines could be improved, as they inhibit several wild-type kinases with low-micromolar IC50 values. Our approach to improve the selectivity of allele-specific inhibitors was to explore a second kinaseinhibitorscaffold. A series of 6,9-disubstituted purines

and fluorescentsensor RBTP for detection of Pd (II) cation was prepared and structurally characterized. Sensor RBTP shows high sensitivity and selectivity to Pd2+ in EtOH/H2O solution (3/2, v/v, pH 7.4, HEPES buffer, 0.5 mM). And sensor RBTP not only exhibited a naked-eye color change from colorless to pink, but also displayed “turn-on” fluorescent sensing for recognition and detection of Pd2+. The
