Rose Bengal lactone is a polyhalogenated derivative of Fluorescein. Rose Bengal lactone is a dye compound described to produce cell membrane damage. Rose Bengal lactone and other Fluorescein derivatives are also described to modulate the function of ATP-sensitive K+ channels. Rose bengal lactone reacts readily with bases so treatment with triethylamine immediately yields the Rose Bengal salt.

In Vitro Use Guide

Rose Bengal lactone at 20 times the IC50 or DMSO alone was incubated with 10 nM beta-lactamase in 10 kDa dialysis tubing. Ten milliliters of this solution was dialyzed at room temperature against three 1 L volumes of 50 mM KPi buffer, pH 7.0, exchanged hourly. After dialysis, the incubation solution was diluted 10-fold and assayed for beta-lactamase activity against 100 mkM cephalothin.
