  Discovery and Structure-Guided Optimization of Diarylmethanesulfonamide Disrupters of Glucokinase–Glucokinase Regulatory Protein (GK–GKRP) Binding: Strategic Use of a N → S (n_N → σ*_S–X) Interaction for Conformational Constraint

  摘要：

  The HTS-based discovery and structure-guided optimization of a novel series of GKRP-selective GK-GKRP disrupters are revealed. Diarylmethanesulfonamide hit 6 (hGK-hGKRP IC50 = 1.2 mu M) was optimized to lead compound 32 (AMG-0696; hcK hGKRP IC50 = 0.0038 mu M). A stabilizing interaction between a nitrogen atom lone pair and an aromatic sulfur system (n(N) -> sigma*(S-X)) in 32 was exploited to conformationally constrain a biaryl linkage and allow contact with key residues in GKRP. Lead compound 32 was shown to induce GI( translocation from the nucleus to the cytoplasm in rats (IHC score = 0; 10 mg/kg po, 6 h) and blood glucose reduction in mice (POC = -45%; 100 mg/kg po, 3 h). X-ray analyses of 32 and several precursors bound to GKRP were also obtained. This novel disrupter of GK-GKRP binding enables further exploration of GKRP as a potential therapeutic target for type II diabetes and highlights the value of exploiting unconventional nonbonded interactions in drug design.
