Disclosed are methods for detecting analytes with indicator systems which may undergo a molecular configurational change upon exposure to the analyte. The configurational change affects a detectable quality associated with the indicator system, thereby allowing detection of the presence or concentration of the analyte.
The invention relates to indicator molecules for detecting the presence or concentration of an analyte in a medium, such as a liquid, and to methods for achieving such detection. More particularly, the invention relates to copolymer macromolecules containing relatively hydrophobic indicator component monomers, and hydrophilic monomers, such that the macromolecule is capable of use in an aqueous environment.

Compositions and methods for determining the presence or concentration of glucose in a sample which may also contain an alpha-hydroxy acid or a beta-diketone. The method uses a compound having at least two recognition elements for glucose, oriented such that the interaction between the compound and glucose is more stable than the interaction between the compound and the alpha-hydroxy acid or beta-diketone, such that the presence of the alpha-hydroxy acid or the beta-diketone does not substantially interfere with said determination.
In certain embodiments, the disclosure relates to methods of treating or preventing a PGAM1 mediated condition such as cancer or tumor growth comprising administering an effective amount of PGAM1 inhibitor, for example, an anthracene-9,10-dione derivative to a subject in need thereof. In certain embodiments, the disclosure relates to methods of treating or preventing cancer, such as lung cancer, head and neck cancer, and leukemia, comprising administering a therapeutically effective amount of a pharmaceutical composition comprising a compound disclosed herein or pharmaceutically acceptable salt to a subject in need thereof.
