Chloride influx measurements. (a) Chloride influx measured upon addition of 1a-d and prodigiosine measured with the chloride probe lucigenin. LUV containing lucigenin in NaNO3 were suspended in an isomolar NaNO3 solution. NaCl was added to the external solution at the beginning of the experiment. Black trace: 1a.HCl, green trace: 1b.HCl, red trace: 1 c.HCl, blue trace: 1d.HCl, magenta trace: prodigiosin and brown trace: blank (10 µL MeOH). Compound concentrations 50 nM. (b) Cartoon representation of lucigenin assay.
