This quinolinone derivative is just a regular white powder under normal light. But under ultraviolet light, it fluoresces blue. Constantinos Neochoritis, a drug design researcher at the University of Groningen, isolated the derivative contained in this 250 mL flask as part of a project to find molecules that can inhibit specific reactions between proteins. Quinolinone derivatives participate in other types of fluorescence, such as that of South American tree frogs.
