| Abstract: | The rapid development of fluorescent probes for monitoring target enzymes is still a great challenge owing to the lack of efficient ways to optimize a specific fluorophore. Herein, a practical two‐dimensional strategy was designed for the development of an isoform‐specific probe for CYP3A4, a key cytochrome P450 isoform responsible for the oxidation of most clinical drugs. In first dimension of the design strategy, a potential two‐photon fluorescent substrate ( NN ) for CYP3A4 was effectively selected using ensemble‐based virtual screening. In the second dimension, various substituent groups were introduced into NN to optimize the isoform‐selectivity and reactivity. Finally, with ideal selectivity and sensitivity, NEN was successfully applied to the real‐time detection of CYP3A4 in living cells and zebrafish. These findings suggested that our strategy is practical for developing an isoform‐specific probe for a target enzyme. |
