Abstract:
This invention relates to glucose-sensitive albumin-binding diboron conjugates. More particularly the invention provides novel diboron compounds, and in particular diboronate or diboroxole compounds, useful as intermediate compounds for the synthesis of diboron conjugates. The diboron compounds are characterized by formula (I), which is: R1-X-R2, and wherein "X" is a mono- to multiatomic linker and where R 1 and R 2 , which may be identical or different, each represents a group of Formula (lla) or (IIb) Also described are diboron conjugates represented by the general Formula (I'), which is: R1'-X'-R2', in which either the moeities R1' or R2' or X' carry a drug that is covalently attached to the diboron compound.
Abstract:
The present invention provides fluorogenic compounds, methods for making the same, and methods for using the same including methods of detecting and/or analyzing phospholipase C (PLC) activity. Compounds of the present invention include fluorogenic compounds, such as, for example, a compound of Formula I. Methods of the present invention include a method of identifying a test substance that inhibits phospholipase C activity, a method of detecting phospholipase C activity in a cell, and a method of detecting aberrant phospholipase C activity in a cell.

Abstract:
EVs are connected to onset and progression of numerous diseases and can be used for their diagnosis. Methods and platform technology to isolate EVs and detect intravesicle phosphoproteins from biofluids are discussed. Secreted extracellular vesicles in biofluids are effectively isolated and phosphoproteins are extracted for detection and identification as biomarkers for disease diagnosis using antibodies, mass spectrometry, or other like methods.
Abstract:
Aspects of the disclosure relate to compositions of enzyme-binding polypeptides (EBPs) that modify the substrate specificity of an enzyme and a method for identifying an EBP that modifies substrate specificity of an enzyme binding at least one substrate, the method comprising: contacting the enzyme with a polypeptide library comprising a plurality of EBPs that bind different epitopes of the enzyme; identifying EBPs that bind to the enzyme to form an EBP-enzyme complex; assaying for the activity level and substrate specificity of the EBP-enzyme complex; and identifying EBPs that modify the substrate specificity of the enzyme by identifying EBPs that, when in an EBP-enzyme complex, have a different substrate specificity than un-complexed EBP; wherein the catalytic rate constant of the EBP- enzyme complex is ≥50% of the un-complexed enzyme for at least one substrate and/or wherein the EBP-enzyme complex retains binding to a substrate.
Abstract:
This invention relates to methods and systems to provide a detection system that detects concentration of an analyte biomolecule (e.g., a protein, a biomarker, etc.) in a sample (e.g., a blood sample) to diagnose a disease. The detection system includes one or more microcantilevers that are immobilized with one or more receptor biomolecules to detect a concentration of an analyte biomolecule in the sample. The detection system further compares the concentration of the analyte biomolecule with a threshold value for diagnosing the disease.
