Synthesis and evaluation of turn-on fluorescent probes for imaging steroid sulfatase activities in cells†
Abstract
We have synthesized and evaluated two self-immobilizing, turn-on fluorescent probes carrying a coumarin molecular framework for imaging intracellular human steroid sulfatase (STS) activity. The 8-fluoromethyl coumarin derivative, which gives stronger fluorescence response in the incubation study with STS preparations, was successfully applied to visualize STS activity in cells.
