Abstract

The invention discloses an aggregation-induced emission fluorescent probe for detecting CYP450 and a preparation method and application thereof. The fluorescent probe is an organic compound based on N-oxide connected tetraphenyl ethylene compounds, and the structural formula of the fluorescent probe is shown in the invention; the fluorescence intensity of the fluorescent probe TPE-CYP changes in the oxygen-deficient environment and in the presence of CYP450, the probe can be used for qualitative and quantitative detection of CYP450, can greatly reduce interference of external detection conditions, and has high detection precision.

Description

technical field [0001] The invention relates to a fluorescent probe and its preparation method and application, in particular to an aggregation-induced emission fluorescent probe for detecting CYP450 (cytochrome P450 enzyme) and its preparation method and application, belonging to the field of chemical technology. Background technique [0002] Cancer is a complex disease with high annual morbidity and mortality. However, cancer drug resistance greatly reduces the cure rate of tumors, and cytochrome P450 enzymes (CYP450) play an important role in the formation of tumor cisplatin resistance. In clinical practice, more than 90% of drugs metabolized by the liver involve CYP450 subtypes. Therefore, a better understanding of the relationship between CYP450 and cancer drug resistance will improve existing therapeutic strategies and facilitate the development of personalized treatments. Small molecule fluorescent probes have a variety of chemical structure modifications, which mak...
