Title: Design and synthesis of an ER-specific fluorescent probe based on carboxylesterase activity with quinone methide cleavage process.
Authors: Hakamata W, Machida A, Oku T, Nishio T.
Abstract: CEs are important enzymes that catalyze the hydrolysis of prodrugs. In this Letter, we present a new mechanistic ER-specific fluorescent probe 1 based on CE activity. Permeation of 1 into cells and subsequent hydrolytic activation by CEs causes spontaneously quinone methide cleavage, resulting in bright red fluorescence in ER with high specificity. Probe 1 was developed for CE activity imaging and inhibitor screening at the cellular level.
