Biological Activity for RuBi-Nicotine
RuBi-Nicotine is a ruthenium-bisbipyridine-caged nicotine, excitable by irradiation with visible light. Undergoes rapid photolysis to release nicotine (< 20 ns); exhibits a high quantum yield. Induces action potential propagation in Retzius neurons of leech ganglia with no detectable toxicity at a concentration of 1 mM.
