The elucidation of signalling pathways relies heavily upon the identification of protein kinase substrates. Recent investigations have demonstrated the efficacy of chemical genetics using ATP analogues and modified protein kinases for specific substrate labelling. Here we combine N(6) -(cyclohexyl)ATPγS with

Two haptens of the insecticide triazophos (O,O-diethyl O-[1-phenyl-1H-1,2,4-triazol-3-yl] phosphorothioate) were synthesized by introducing appropriate spacers in the O-ethyl site of the analyte molecular structure. First, thiophosphoryl chloride (PSCl(3)) reacts with methanol at low temperature to give O-ethyl dichlorothiophosphate. After reacting

Elemental [35S]sulfur was shown to equilibrate with the sulfur of thiophosphoryl chloride when these materials are heated together. This isotopic exchange reaction is the basis of a convenient, microscale synthesis of high specific activity [35S]PSCl3. [35S]Thiophosphoryl chloride is otherwise not
