利用光药理学对细胞功能进行时空控制的扰动促进了生物网络的阐明,并为精确医学开辟了新的机会。在这里,我们引入了细胞可穿透的光开关小分子,称为光jasps,以光学控制肌动蛋白细胞骨架的动力学和依赖它的细胞功能。这些光依赖效应器是由F-肌动蛋白稳定的海洋去脂肽jasplakinolide通过偶氮苯光开关功能化来设计的。我们证明了光jasps可以用来控制细胞活力、细胞运动和细胞骨架信号,具有光提供的高空间和时间分辨率。我们预计,光针将在细胞生物学研究的不同领域得到应用。它们还可以为针对普遍存在的肌动蛋白细胞骨架的化疗药物的开发提供模板,并在μm范围内进行精确控制。
The spatiotemporally-controlled perturbation of cellular function using photopharmacology has facilitated the elucidation of biological networks and opens up new opportunities for precision medicine. Here, we introduce cell- permeable photoswitchable small molecules, termed optojasps, to optically control the dynamics of the actin cytoskeleton and cellular functions that depend on it. These light-dependent effectors were designed from the F-actin-stabilizing marine depsipeptide jasplakinolide by functionalizing them with azobenzene photoswitches. We demonstrate that optojasps can be employed to control cell viability, cell motility, and cytoskeletal signalling with the high spatial and temporal resolution that light affords. We expect that optojasps will find applications in diverse areas of cell biological research. They may also provide a template for the development of chemotherapeutics targeting the ubiquitous actin cytoskeleton with precision control in the μm range.
