(Figure Presented) Unleashed inside cells: The signaling molecule PI(3,4,5)P3 is prepared in a form that allows its cellular uptake and subsequent activation by light (see picture). The rapid eight-step synthetic sequence yields a stable derivative of the signaling molecule with high biological activity after deprotection ("uncaging") with a laser flash, in live cells.
