Photocage
WebThe regioselective oxidative cleavage of a C=C bond from a boron-dipyrrolemethene (BODIPY) photocage has been realized under 630 nm illumination; this generated an aldehyde compound and a thiol fluorescent probe. This reaction was demonstrated inside live cells by monitoring the aldehyde release in real time. In particular, the photocage can … WebMar 28, 2024 · The phototoxicity to tissues is dependent on light frequency and wavelength as expressed in the Planck-Einstein equation: E = hν = hc λ where E is the energy of the photon, ν is the light frequency, λ is the light wavelength, c is light's velocity in vacuum and h is the Planck's constant (6.626×10 −34 J·s) [ 16, 99 ].

Light-controlled uncaging of the drug–fluorophore conjugate resulted in increased cellular fluorescence, which was found to correlate with cytotoxicity. ...
Webuct of the BODIPY photocage, possibly from solvent trapping of an intermediate carbocation. Curiously, unlike 1-4 and 6, the brominated compound 5 was found to be unstable. It decomposes after 1 day stored on the shelf in the dark, and photolysis of fresh-ly prepared and purified 5 led to secondary products in addition to WebThe study of the opioids, their receptors, and the development of remediation strategies has benefitted from derivatization of the opioids as chemical tools. While these studies have primarily focused on the opioids in the context of the opioid receptors, these chemical tools may also play a role in delineating mechanisms that are independent ...
