- Compounds and methods for detecting tripeptidyl protease I
-
The present invention provides compounds useful for the detection of the enzyme tripeptidyl protease I (TPP-1). The invention also provides methods of making such compounds, methods of using such compounds, and kits and compositions containing such compounds. In one embodiment, Gly-L-Pro-L-Ser-1-anthraquinonylhydrazide, in combination with p-anisaldehyde, is used to detect TPP-1.

- EDC-mediated condensations of 1-chloro-5-hydrazino-9,10-anthracenedione, 1-hydrazino-9,10-anthracenedione, and the corresponding anthrapyrazoles
-
The EDC-mediated condensation of 1-chloro-5-hydrazino-9,10-anthracenedione afforded an N-1 acyl anthrapyrazole instead of the expected hydrazide. The regiochemistry of the N-acyl substituent was assigned on the basis of an extensive set of NMR experiments, and identification of this isomer suggests a reaction sequence based on initial acylation and subsequent cyclization. In contrast, the parallel reaction of 1-hydrazino-9,10-anthracenedione proceeded to afford the expected hydrazide.
