  • Patent number: 7772402
    Abstract: The invention relates to compounds having general formula I in which X represents an optically detectable moiety, n is an integer with 1?n?20, R1 is an unbranched or branched alkyl group having 1 to 20 carbon atoms, and R2 is hydrogen or —CH2—O—R3 group, wherein R3 has the same meaning as R1. These compounds are useful as inhibitors of lipolytic enzymes and can be used as tools for analysis as well as discrimination of lipolytic enzymes in biological samples.
