We synthesized and evaluated new zwitterionic inhibitors against glycoside hydrolase-like phosphorylase Streptomyces coelicolor (Sco) GlgEI-V279S which plays a role in α-glucan biosynthesis. Sco GlgEI-V279S serves as a model enzyme for validated anti-tuberculosis (TB) target Mycobacterium tuberculosis (Mtb) GlgE. Pyrrolidine inhibitors 5 and 6 were designed based on transition state considerations and incorporate a phosphonate on the pyrrolidine moiety to expand the interaction network between the inhibitor and the enzyme active site. Compounds 5 and 6 inhibited Sco GlgEI-V279S with K i = 45 ± 4 μM and 95 ± 16 μM, respectively, and crystal structures of Sco GlgE-V279S-5 and Sco GlgE-V279S-6 were obtained at a 3.2 Å and 2.5 Å resolution, respectively.
