Fluorescent Labeling of a Target Protein with an Alkyl Diazirine Photocrosslinker Bearing a Cinnamate Moiety.
Chemistry, an Asian journal(2024)
摘要
A novel fluorogenic alkyl diazirine photocrosslinker bearing an o-hydroxycinnamate moiety has been developed for identification of the targets of bioactive molecules. The o-hydroxycinnamate moiety can be converted to the corresponding 7-hydroxycoumarin derivative, which should be created on the interacting site within the photocaptured target protein. The label yield and fluorescence intensity have been immensely improved in comparison with our previous aromatic crosslinkers to facilitate target identification in small quantities.
