The present invention provides compounds useful for treating, ameliorating or preventing a disease or disorder that is caused, induced or characterized by abnormal reduction in glutamate transporter activity or abnormal increase in extracellular CNS glutamate concentration in a subject. In certain embodiments, the compound stimulates a glutamate transporter.

The present disclosure relates to novel pyridine-containing macrocyclic compounds and libraries thereof that are useful as research tools for drug discovery efforts. This disclosure also relates to methods of preparing these compounds and libraries and methods of using these libraries, such as in high throughput screening. In particular, these libraries are useful for evaluation of bioactivity at existing and newly identified pharmacologically relevant targets, including G protein-coupled receptors, nuclear receptors, enzymes, ion channels, transporters, transcription factors, protein-protein interactions and nucleic acid-protein interactions. As such, these libraries can be applied to the search for new pharmaceutical agents for the treatment and prevention of a range of medical conditions.

Methods for removing oxyanions from water according to the following steps: (i) dissolving an oxyanion precipitating compound into the aqueous source to result in precipitation of an oxyanion salt of the oxyanion precipitating compound; and (ii) removing the oxyanion salt from the water containing the oxyanion to result in water substantially reduced in concentration of the oxyanion; wherein the oxyanion precipitating compound has the following composition: ##STR00001##
wherein A is a ring-containing moiety and X.sup.m is an anionic species with a magnitude of charge m. The invention employs bis-iminoguanidinium compounds according to Formula (1a) as well as neutral precursor compounds according to Formula (1), which can be used for removing undesirable species from aqueous solutions or air, such as removal of sulfate from water and carbon dioxide from air.
