摘要

The present invention provides N-acylidihydroresorufin derivatives of the general formula: IMAGE (I) wherein R1 is a lower alkyl, aryl or aralkyl radical, which can be substituted by carboxyl or sulphonic acid residues, R2, R3 and R4, which can be the same or different, are hydrogen or halogen atoms or lower alkyl or lower alkoxy radicals, Y is an -NR5R6 or -OR7 group, wherein R5 and R6 are, in each case, hydrogen atoms or lower alkyl radicals, which can be substituted by carboxyl or sulphonic acid residues, or together represent a hydrocarbon bridge optionally interrupted by hereto atoms and R7 is a lower alkyl radical which can be substituted by a lower alkoxy or poly-lower alkoxy radical.
