摘要:
A nanoplasmonic resonator (NPR) comprising a metallic nanodisk with alternating shielding layer(s), having a tagged biomolecule conjugated or tethered to the surface of the nanoplasmonic resonator for highly sensitive measurement of enzymatic activity. NPRs enhance Raman signals in a highly reproducible manner, enabling fast detection of protease and enzyme activity, such as Prostate Specific Antigen (paPSA), in real-time, at picomolar sensitivity levels. Experiments on extracellular fluid (ECF) from paPSA-positive cells demonstrate specific detection in a complex bio-fluid background in real-time single-step detection in very small sample volumes.

The present invention relates to () non-peptide aspartyl protease inhibitors; (ii) methods for modulating the processing of an amyloid precursor protein (APP); (iii) methods for modulating the processing of a tau protein (τ-protein); and (iv) methods for treating neurodegenerative diseases. For instance, in one embodiment, the present invention provides a method for modulating the processing of an amyloid precursor protein (APP), the method comprising contacting a composition containing the APP with an aspartyl protease inhibitor having the formula: wherein: R1, R2 and R3 are members independently selected from the group consisting of alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, substituted arylalkyl, aryloxyalkyl, substituted aryloxyalkyl, heteroaryl, substituted heteroaryl, heteroarylalkyl, substituted heteroarylalkyl, heterocycles, substituted heterocycles, heterocyclicalkyl and substituted heterocyclicalkyl; and R5 and R6 are independently selected from the group consisting of hydrogen, halogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, substituted arylalkyl, aryloxyalkyl and substituted aryloxyalkyl; or R5 and R6 and the carbons to which they are bound join to form an optionally substituted carbocyclic or heterocyclic fused ring system having a total of 9- or 10-ring atoms within the fused ring system.
摘要:
A library of candidate target binding fragments (CTBF's) each CTBF being a small organic molecule and having a linkable functional group (LFG) or blocked form thereof (BLFG), wherein the LFG or BLFG contains a linking group (LG), the LG being a disulfide group.
摘要:
The present invention is directed to novel methods for identifying small molecule ligands that are capable of binding with high affinity to a biological target molecule of interest. High affinity binding ligands identified by the described methods find use, for example, as small molecule lead compounds that may they themselves be, or may give rise to, novel therapeutic drugs. More specifically, the subject invention is directed to methods for identifying a ligand that binds to a target biological molecule of interest, wherein a population of small organic compounds are selected and then “pre-screened” to identify those that are capable of binding to the molecular target. The small organic compounds that are identified during the pre-screening as being capable of binding to the target (or structurally related analogs thereof) are then coupled in various combinations with a linker element to provide a library of potential ligands for binding to the target molecule that is then screened to identify ligands having very high binding affinities for the molecular target. Ligands obtained by this method and methods for using those ligands for inhibiting the interaction between two biological molecules are also provided.

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:
Methods, compositions, and devices for synthesizing combinatorial libraries of various useful compounds, such as benzodiazepines, prostaglandins, .beta.-turn mimetics and glycerol-derived drugs is described. In order to expediently synthesize such combinatorial libraries of derivatives based upon these core structures, a general methodology for the solid phase synthesis of these derivatives is also provided. This disclosure thus also describes an important extension of solid phase synthesis methods to nonpolymeric organic compounds.
