| Research Abstract |
We investigated the screening of a potent inhibitor and the functional analysis of y-secretase, which was identified as an important therapeutic target for Alzheimer's disease (AD). During the course of our investigation based on potent inhibitor DAPT (1), we developed a fitile synthetic method for a photoaffinity probe by utilizing the polymer-bound reagent. Furthermore, the utility of the reagent was demonstrated by synthesis of the probe and the photoaffinity labeling experiments of the probe clarified that the major direct target molecules for the DAPT are preseniline 1 C-terminal fragments (PS1 CTFs), which were discovered from the genetically investigation of familial AD. Additionally, a competing photolabeling experiment of the probe against various class of inhibitors, we dissected the inhibitory mechanism of DAPT.
