  Chemical Modifications of Peptide Sequences via S-Alkylation Reaction

  摘要：

  A chemoselective, convenient, and mild synthetic strategy to modify peptides on a cysteine sulfhydryl group is described. It simply requires activated molecular sieves to selectively promote S-alkylation in the presence of peptide nucleophilic functionalities. The procedure is easy to perform, fast, and provides high yields even in the case of poor electrophilic groups. Moreover, the method allows an efficient one-pot poly alkylation, proving that the sulfhydryl reactivity does not rely on its specific position within the peptide sequence.

  A palladium selective chemosensor based on a fluorescein-allyloxy benzene scaffold and a method of detecting palladium ions in a fluid sample with the chemosensor, whereby the fluid sample is contacted with a solution that includes water and the chemosensor to form a mixture. An ultraviolet visible absorption profile and/or a fluorescence emission profile of the mixture is measured to determine a presence or absence of palladium ions in the fluid sample, wherein the chemosensor has an ultraviolet visible absorption peak at 315 to 325 nm and a fluorescence emissions peak at 380 to 400 nm in the solution, and wherein a bathochromic shift in the ultraviolet visible absorption peak to 338 to 342 nm in the mixture and/or a bathochromic shift in the fluorescence emissions peak to 530 to 550 nm in the mixture indicates the presence of palladium ions in the fluid sample.

  Methods are provided for detecting formation of oligomeric complexes of molecules on the surface of cell membranes. These methods employ pairs of tagged probes and cleaving probes, each of which binds specificly to a cell surface molecule. The tagged probe includes a molecular tag that is linked to a first binding compound through a cleavable linkage, and the cleaving probe includes a second binding agent and a cleavage-inducing moiety that can cleave the linkage when within a defined proximity thereto. Binding of the two probes to cell surface molecules that have formed an oligomeric complex results in release of the molecular tag from the binding compound, providing a measure of formation of the complex.
