Webb16 maj 2006 · We have determined that GA and the fluorescent analogue BODIPY-GA (BDGA) both demonstrate slow, tight binding to purified Hsp90. BDGA, used to characterize the kinetics of ligand–Hsp90 interactions, was found to bind Hsp90α with koff = 2.5 × 10 −3 min −1, t1/2 = 4.6 h, and Ki * = 10 nM.
