Abstract

Photocaging facilitates non-invasive and precise spatio-temporal control over the release of biologically relevant small- and macro-molecules using light. However, sub-cellular organelles are dispersed in cells in a manner that renders selective light-irradiation of a complete organelle impractical. Organelle-specific photocages could provide a powerful method for releasing bioactive molecules in sub-cellular locations. Herein, we report a general post-synthetic method for the chemical functionalization and further conjugation of meso-methyl BODIPY photocages and the synthesis of endoplasmic reticulum (ER)-, lysosome-, and mitochondria-targeted derivatives. We also demonstrate that 2,4-dinitrophenol, a mitochondrial uncoupler, and puromycin, a protein biosynthesis inhibitor, can be selectively photoreleased in mitochondria and ER, respectively, in live cells by using visible light. Additionally, photocaging is shown to lead to higher efficacy of the released molecules, probably owing to a localized and abrupt release.

摘要

光镊技术可利用光实现对生物相关的小分子和生物大分子的非侵入性和精确时空控制释放。然而,亚细胞细胞器在细胞内的分布方式使得对完整细胞器进行选择性光照射变得不切实际。细胞器特异性光笼可以为在亚细胞位置释放生物活性分子提供一种强大的方法。在此,我们报告了一种通用的介观甲基 BODIPY 光笼的化学功能化和进一步共轭的后合成方法,以及内质网(ER)、溶酶体和线粒体靶向衍生物的合成方法。我们还证明,线粒体解偶联剂 2,4-二硝基苯酚和蛋白质生物合成抑制剂嘌呤霉素可以分别通过可见光在活细胞中线粒体和 ER 中选择性光释放。此外,光笼化被证明可以提高释放分子的功效,这可能是由于局部和突然的释放。
