Next Generation Opto-Jasplakinolides Enable Local Remodeling of Actin Networks.

The natural product jasplakinolide is widely used to stabilize F-actin. Based on extensive structure-activity relationship studies, we have developed a new generation of photoswitchable jasplakinolides that feature rationally designed red-shifted azobenzene photoswitches. Our lead compound, nOJ, can be activated with longer wavelengths in the visible range (e.
