  • Publication number: 20240091213
    Abstract: Provided herein are bifunctional compounds that bind tau protein and/or promote targeted ubiquitination for the degradation of tau protein. In particular, provided are compounds that can bind tau protein, a protein whose aggregation is implicated in a variety of neurodegenerative disease (e.g., tauopathies), and can promote its degradation by recruiting an E3 ubiquitin ligase (e.g., Cereblon), which can ubiquitinate tau protein, marking it for proteasomal degradation. Also provided are radiolabeled forms of the bifunctional compounds, pharmaceutical compositions comprising the bifunctional compounds, methods of detecting and/or diagnosing neurological disorders, methods of detecting and/or diagnosing pathological aggregation of tau protein (e.g., in the central nervous system), methods of treating and/or preventing neurological disorders, and methods of promoting the degradation of tau protein by E3 ubiquitin ligase activity in a subject by administering a compound or composition described herein.

  • Patent number: 7727740
    Abstract: The present invention provides methods for screening for one or more chemical agents that modulate the enzymatic activity of an L-2-hydroxy acid oxidase. The methods comprise the steps of (a) contacting an L-2-hydroxy acid oxidase, in a solution in vitro, with one or more chemical agents in the presence of a substrate that is capable of being oxidized by the L-2-hydroxy acid oxidase; (b) measuring the enzymatic activity of the L-2-hydroxy acid oxidase in the presence of the chemical agent to identify one or more candidate chemical agents that modulate L-2-hydroxy acid oxidase activity in vitro; and (c) administering the one or more identified candidate chemical agents to a test animal and measuring one or more physiological parameters.

  • Publication number: 20050251869
    Abstract: Transgenic mice having human CETP genes are useful models for the action of niacin in humans. Such animals exhibit an increase in HDL-C and the HDL-C/non-HDL-C ratio and a decrease in non-HDL-C when they are treated with niacin. The changes in HDL-C and non-HDL-C appear to be dose-dependent.
