title: Designing better coumarin-based fluorogenic substrates for PTP1B.
abstract: As part of a program to develop better PTP1B fluorogenic substrates that more closely mimic the functionality found in the natural substrate, we have prepared and evaluated nine novel analogs of 4-methylumbelliferone phosphate (MUP) with a variety of additional groups occupying the second phosphate binding pocket.
