Abstract
Although considerable effort has been devoted to developing Grb2 SH2 domain-binding antagonists, important questions related to ligand specificity, and identification of intracellular targets remain unanswered. In order to begin addressing these issues, the design, synthesis, and evaluation of a novel biotinylated macrocycle are reported that bears biotin functionality at a C-terminal rather than the traditional N-terminal position. With a Grb2 SH2 domain-binding Keq value of 3.4 nM, the title macrocycle (5) is among the most potent biotinylated SH2 domain-binding ligands yet disclosed. This should be a useful tool for elucidating physiological targets of certain Grb2 SH2 domain-binding antagonists.
