Compounds comprising a cross-linking moiety and a protecting group are described herein along with their methods of use. The cross-linking moiety may comprise an indoxyl and the protecting group may comprise a sugar (e.g., a glucuronide or glucoside), phosphoester, or sulfoester group. The cross-linking moiety and protecting group may be attached to each other via an oxygen atom, sulfur atom, or linker. In some embodiments, the linker attaching the cross-linking moiety and protecting group is a self-immolative linker. A compound of the present invention may cross-link under physiological conditions and/or in vivo.

A novel indicator platform comprises a plurality of 1 H-lndol-3-yl indicator compounds that are capable of converting to a signalophore compound in response to an external stimulus. In one class of indicator compounds, the resulting signalophores are 2-benzylideneindoline compounds that are formed by an intermolecular Aldol-type process; in a further class of indicator compounds, the resulting signalophores are 10H-indolo[1,2-a]indole compounds that are formed by an intramolecular Aldol-type process. The indicators can be used in a wide array of applications relating, for example, to biological systems or optical data storage.

The subject invention discloses materials and methods for the design, synthesis, and biochemical evaluation of chromogenic substrate compounds for sialidases of bacterial, viral, protozoa, and vertebrate (including humans) origin. In particular, this invention provides a novel class of effective compounds as chromogenic substrates of these sialidases which yield chromogenic products after reactions catalyzed by sialidase take place. Also provided are methods of making these substrate compounds, methods of diagnosis and prognosis of sialidase related diseases using these substrate compounds.

The present invention relates to synthetic compounds that are active on plants, especially as legume nodulation factors, and also as plant growth stimulators, and to methods for preparing such compounds, which are of formula (I):
This invention provides novel chromogenic enzyme substrates which are indoxyl β-D-ribofuranosides. A process for their production is provided. Methods for detecting β-D-ribofuranosidase activity are given. The advantages of these novel compounds includes: detecting β-D-ribofuranosidase activity with high sensitivity and low substrate concentrations and use with other enzyme indicators in situations where a plurality of enzyme activities is to be visualized simultaneously e.g. for identifying bacteria growth on solid growth media. The synthesis and use of 5-bromo-4-chloro-3-indolyl-β-D-ribofuranoside is exemplified.
