An approach for differentiating isozymes. Construction of libraries containing short aromatic peptides as part of a method to design selective inhibitors against lipases

Bioorg Med Chem Lett. 2012 May 1;22(9):3147-51. doi: 10.1016/j.bmcl.2012.03.048. Epub 2012 Mar 21.

Abstract

Through synthesis and assays of peptidyl substrates, we could select substrates having peptidyl complementary against lipases. The best substrate showed 20-fold improved K(m) relative to non-peptidyl substrate. Using this information, we generated selective inhibitors. Lipase activities with peptidyl substrates were represented as fingerprints. Differences in fingerprints reflect different structures near active site of lipases, could be used for generating selective inhibitors.
