    摘要: This invention pertains to the in vitro detection of proteases using a single peptide-conjugate nanocrescent surface enhanced Raman scattering (SERS) probes with at least nanomolar sensitivity. The probe enables detection of proteolytic activity in extremely small volume and at low concentration. In certain embodiments the probes comprise an indicator for the detection of an active protease, where the indicator comprises a nanocrescent attached to a peptide, where said peptide comprises a recognition site for the protease and a Raman tag attached to the peptide.

    摘要: A method of preparing an olefin comprising: reacting a polyol in the presence of a carboxylic acid, such that an olefin is produced by the deoxygenation of the polyol. The reacting step can comprise (a) providing a composition comprising the polyol, (b) heating the composition, and (c) introducing the carboxylic acid to the composition wherein the introducing step occurs prior to, at the same time as, or subsequent to the heating step. In one embodiment, the polyol is glycerol, the carboxylic acid is formic acid, and the olefin is allyl alcohol, which is produced at a yield of about 80% or greater.

    摘要: A method is presented for the preparation and use of fluorogenic peptide substrates that allows for the configuration of general substrate libraries to rapidly identify the primary and extended specificity of enzymes, such as proteases. The substrates contain a fluorogenic-leaving group, such as 7-amino-4-carbamoylmethyl-coumarin (ACC). Substrates incorporating the ACC leaving group show comparable kinetic profiles as those with the traditionally used 7-amino-4-methyl-coumarin (AMC) leaving group. The bifunctional nature of ACC allows for the efficient production of single substrates and substrate libraries using solid-phase synthesis techniques.
