Brief summary: crystals were grown in hanging drops from mixtures of 10 μl reservoir solution (0.1 M ammonium acetate and 12% polyethylenglycol 3350 in 0.1 M Hepes, pH 7) with 20 μl human liver FBPase preincubated with inhibitor. Crystals were harvested, flash cooled, and data was collected at the Swiss Light Source (SLS) beam line X10SA. The atomic coordinates of the FBPase complex structures with compounds 1b and 7a have been deposited at the Protein Data Bank under accession codes 2vt5 and 2jjk, respectively.

    • Conformational analysis of the linker with constrained sulfonylurea anchors was performed in MOE using molecular dynamics at T = 600 K with minimizations of MD snaphots saved at regular intervals. The MMFF94x potential without solvation correction was used.

    • MM-PBSA calculations were performed using the protein structure 6a. For the monomer calculations, the C-C bond in the middle of the C6-linker was cut and relaxed. MM-PBSA free energies were calculated for the minimized complex structures with parameters and general set-up as described in: Kuhn, B.; Gerber, P.; Schulz-Gasch, T.; Stahl, M. J. Med. Chem. 2005, 48, 4040.
