The preparation of beta-EgadMe and alpha-EgadMe, magnetic resonance (MR) contrast agents that can be used for in vivo detection of beta-galactosidase, is described. Diastereomerically pure beta-EgadMe can be synthesized by kinetically resolving the starting material as described in Step 1.

Autophagy, 6(7), 879-890 (2010-07-22)
A number of signaling mechanisms have been implicated in the regulation of autophagic trafficking. TOR kinase activity, cAMP levels, and the GAAC pathway have all been suggested to be involved. Here, we closely analyzed the stimuli that underlie induction of
