Abstract
Chromogenic and fluorogenic substrates for .beta.-lactamase, methods for synthesis thereof and methods for detecting .beta.-lactamase in a sample are provided. The substrates are substantially colorless or substantially nonfluorescent .beta.-lactam compounds which include an electronegative leaving group. The leaving group comprises a carbamate, carbonate, thiocarbamate or thiocarbonate linkage and a fluorescent moiety or a moiety capable of producing a visually detectable colored product. Upon cleavage of the lactam ring by .beta.-lactamase, the leaving group is liberated and fluorescence or a colored product is produced.
