摘要:
Analogs of ShK toxin and methods for using such ShK analogs. The ShK analogs generally comprise ShK toxin attached to a chemical entity (e.g. an atom, molecule, group, residue, compound, moiety, etc.) that has an anionic charge. The ShK analogs may be administered to human or non-human animal subjects to cause inhibition of potassium channels or to otherwise treat diseases or disorders. In some embodiments, the chemical entity to which the ShK toxin is attached may be chosen to provide selective inhibition of certain potassium channels (e.g., Kv1.3 channels) over other potassium channels (e.g., Kv1.1 channels). In come embodiments, the chemical entity to which the ShK toxin is attached may include a fluorophore and such fluorophore-tagged ShK analogs may be used in flow cytometry alone, or in conjunction with class II tetramers that can detect autoreactive cells.
