WebMar 28, 2024 · Photocaged compounds fall in the category of light-sensitive substances that allow to hinder the function of a compound and, posteriorly, recover its bioactivity under light irradiation at a desirable location [15,17,35,36]. Photocaged compounds have a common structure in which a PPG is covalently bonded to the active site of a biologically ... WebJul 15, 2024 · Photocaged compounds are comparatively easy to design because the structure of the active form is usually known beforehand, i.e., as a validated PROTAC, and the structure-activity relationships of either ligand (for the E3 ubiquitin ligase and POI, respectively) are usually available (Figure 1 D).Photocaging of the ligand for the ubiquitin …
WebFeb 1, 2024 · Photocaging allows for precise spatiotemporal control over the release of biologically active compounds with light. Most photocaged molecules employ organic photolabile protecting groups; however, biologically active compounds often contain functionalities such as nitriles and aromatic heterocycles that cannot be caged with … WebPhotocaged compounds are applied for implementing precise, optochemical control of gene expression in bacteria.

WebDec 23, 2024 · Photoactivatable (alternatively, photoremovable, photoreleasable, or photocleavable) protecting groups (PPGs), also known as caged or photocaged compounds, are used to enable non-invasive spatiotemporal photochemical control over the release of species of interest. Recent years have seen the develop … WebPhotocaged compounds 1-4 and 6 are thermally stable in the dark. Boiling these compounds in MeOH for 1 h in a foil-wrapped vessel led to no change in the 1H NMR spectrum (see SI for spectra). Compound 5 is unstable in all forms.
