Outline of Final Research Achievements

Design and exploration of fluorescence probe compounds for the Pin1 binding pocket were performed, in which the molecules were expected to increase the fluorescence when binding to Pin1 proteins. By replacement of heteroaromatic moiety of a known Pin1 inhibitor with the fluorescent moiety which is responding to the environmental polarity. One of the inhibitory compound bearing fluorescence molecular showed good environmental response in low-polarity organic solvents and slight increase of the fluorescence in the presence of Pin1 proteins. However, the compound was assumed to have a significant amount of non-specific binding to Pin1 other than the substrate binding pocket.
Other potent Pin1 inhibitors were also explored for future development of the probe, and the compound bearing azocanyl moiety for the proline pocket was found to have potent Pin1 inhibiting activity.
