The Pipecoliclinker is a newhighlyversatilehandle which immobilizes on solidsupport through a carboxylic acid function a wide range of amines, alcohols, and hydrazines. The anchoring step on pipecolic resin is very easy and efficient, and compounds are released with high purities upon acidic treatment. During this treatment, an oxazolonium intermediate is hydrolyzed, yielding the cleavage of ester
application of the pipecoliclinker is presented. This newversatilehandle can immobilize primary, secondary, and aromatic amines, as well as alcohols, phenols, and hydrazides, on a solidsupport. Compared with other linkers, the anchoring step is easy and efficient. The release of final products from the resin proceeds upon acidic treatment with high purities. The pipecoliclinker offers the promise

The present invention provides acetal derivatives of luciferin and methods for using such derivatives in enzyme activity assays where the luciferin derivative serves as a substrate for a desired enzyme and is a prosubstrate for luciferase (a proluciferin). Thus, by providing luciferin derivatives having a particular enzyme recognition site for a desired nonluciferase enzyme (a reactive chemical group in a molecule referred to as a substrate for the enzyme) coupled to the luciferin backbone (or other chemical moiety constituting a suitable substrate for luciferase), e.g., derivatives having modifications at the carboxyl group of D- luciferin or aminoluciferin as well as optionally other modifications, nonluciferase enzymes may be measured in a bioluminescent assay.
