Abstract:
We have recently reported that allosteric modulation of the chaperone protein Hsp901 can be achieved in an allosteric fashion using a family of 2-phenyl-benzofuran derivatives that target an allosteric pocket at the C-terminal domain of the protein.2,3 These ligands are mainly activators of the chaperone ATPase activity3 and are accelerators of the protein internal dynamics.4 As a result, they tune Hsp90 chaperone activity in ways that we are just beginning to unravel.
We are going to present the synthetic approaches towards an expanded library of about 40 benzofuran derivatives diversified at positions R1 and R2 along with the interaction studies with full length Hsp905 and the effects on Hsp90 enzymatic and chaperoning activity.
