WebAug 1, 2024 · Caged lipids are based on natural lipids to which an aromatic and photo-removable protecting group was added that prevents molecular recognition by the cellular machinery. A simple pulse of light is sufficient to cleave the chemical bond between the lipid and the protecting group, releasing the lipid of interest ( Figure 3 a) [ 50 ]. WebJan 1, 2014 · Lipid derivatives that can be activated by light, often referred to as 'caged' lipids, are useful tools to manipulate intact cells non-invasively. Here we focus on …
WebJul 19, 2024 · As reported, caged lipids bearing negatively charged sulfonate groups are selectively localized at the plasma membrane (PM) while neutral lipids mostly localized at internal membranes (IMs). 39 Therefore, we chose negatively charged Atto-532 and neutral sulfoRhB to selectively localize caged lipids at the PM and IMs, respectively . WebSphingolipid phosphate analogues bearing 7-(diethylamino)coumarin (DECM) and 4-bromo-5-hydroxy-2-nitrobenzhydryl (BHNB) groups in a photolabile ester bond were synthesized. The ability of the “caged” ceramide 1-phosphate analogues to release the bioactive parent molecule upon irradiation at 400−500 nm was demonstrated by stimulation of …
WebWe focus on photoremovable protecting groups that lead to subcellular restricted localization and activation and discuss alternative techniques. We emphasize the development of organelle targeting of caged lipids and discuss recent advances in chromatic orthogonality of caging groups for future applications. KW - Fluorescence. KW - Lipid transport Small molecules are easily modified by chemical synthesis and therefore were among the first to be modified and used in biological studies. A wide variety of caged small molecules exist. Photochemical reactions can convert a nonemissive reactant into a fluorescent product. These reactions can be exploited in super-resolution microscopy to allow localization beyond the diffraction limit.
