Diaminoxanthones
WebAbstract A study of some parameters which influence the Ullmann-Goldberg condensation for the synthesis of N-phenylanthranilic acids was done, showing that these acids can be obtained efficiently using water as solvent. WebSep 5, 2024 · A sensing mechanism for single-molecule detection of enzymatic activity that could be applied to many other biologically relevant targets is introduced in this proof-of-principle study. A dual-activatable, fluorogenic probe was developed to sense esterase activity with single-molecule resolution. Without enzymatic pre-activation, the …

WebSep 5, 2024 · A quantitative framework for the development of new fluorogenic dyes is developed, determining that the lactone–zwitterion equilibrium constant (KL–Z) is sufficient to predict fluorogenicity. Rhodamine dyes exist in equilibrium between a fluorescent zwitterion and a nonfluorescent lactone. Tuning this equilibrium toward the …
