Chemical Name: Ammoniated ruthenium oxychloride

Biological Activity

Blocks Ca2+ uptake and release from mitochondria, and Ca2+ release from ryanodine-sensitive intracellular stores. Also blocks cell membrane-located capsaicin-activated cation channels (IC50 = 14 nM) and voltage-sensitive Ca2+ channels to inhibit neurotransmitter release.

Technical Data

Soluble to 10 mM in water
Store at RT
