8RK59, a Bodipy probe, is a potent UCHL1 (ubiquitin C-terminal hydrolase L1) inhibitor, with an IC50 close to 1 μM. 8RK59 could penetrate and label living cells. BodipyFL-alkyne is coupled to the azide of 8RK64 (HY-148254) using copper(I)-mediated click chemistry, resulting in compound 8RK59[1]. | [Biological Activity]
8RK59 is a cellularly active covalent fluorescent probe th at targets selectively active UCHL1 (ubiquitin carboxy-terminal hydrolase L1). 8RK59 selectively and spatiotemporally report UCHL1 activity in zebrafish embryos. | [References]
