Discovery of Carbohydrate Sulfotransferase Inhibitors from a Kinase-Directed Library We thank Sharon Long and Dave Keating for providing both the NodH sulfotransferase and APS Kinase during our preliminary experiments and Jack Kirsch for numerous helpful conversations. J.I.A. and K.G.B were supported by NIH Molecular Biophysics Training Grant (No. T32GM0895). This research was funded by grants to C.R.B. from the Pew Scholars Program, the W. M. Keck Foundation and the American Cancer Society (Grant No. RPG9700501BE).
