Developing an isoflavone-based fluorescent probe for monitoring carboxylesterase on studying medicine-food homology samples

Abstract

Herein, for monitoring the carboxylesterase (CE) level on studying medicine-food homology samples, an isoflavone-based fluorescent probe, IFone-CE, was developed on the basis of the representative Formonetin and the extended saturated fatty acidic chain as the recognition group. A typical turning-on was established, which remained the modification potential. The probe IFone-CE suggested general advantages including a relatively rapid response, stable optical performance in various working conditions of pH, temperature, and storage. It also exhibited practical linear range, high sensitivity, high selectivity, and low cyto-toxicity. The solution system containing IFone-CE achieved monitoring the biological efficacy of medicine-food homology samples. In the confocal imaging, IFone-CE realized the reduction and promotion effect of the samples in living colorectal cells. This work raised beneficial insights for the effective utilization of resources and medicinal chemistry research.
