  Monosaccharide-Linked Inhibitors of O⁶-Methylguanine-DNA Methyltransferase (MGMT):  Synthesis, Molecular Modeling, and Structure−Activity Relationships

  摘要：

  A series of potential inhibitors of the human DNA repair protein O-6-methylguanine-DNA methyltransferase (MGMT) were synthesized, characterized in detail by NMR, and tested for their ability to deplete MGMT activity in vitro. The new compounds, omega-[O-6-R-guan-9-yl]-(CH2)(n)-beta -d-glucosides with R = benzyl or 4-bromothenyl and omega = n = 2, 4, ... 12, were compared with the established inhibitors O-6 -benzylguanine (O-6-BG), 8-aza-O-6-benzylguanine (8-aza-BG), and O-6-(4-bromothenyl)guanine (4-BTG), which exhibit in an in vitro assay IC50 values of 0.62, 0.038, and 0.009 muM, respectively. Potential advantages of the glucosides are improved water solubility and selective uptake in tumor cells. The 4-BTG glucosides with n = 2, 4, 6 show moderate inhibition with an IC50 of ca. 0.5 muM, while glucosides derived from BG and 8-aza-BG showed significantly poorer inhibition compared to the parent compounds. The 4-BTG glucosides with n = 8, 10, 12 were effective inhibitors with IC50 values of ca. 0.03 muM. To understand this behavior, extensive molecular modeling studies were performed using the published crystal structure of MGMT (PDB entry: 1QNT). The inhibitor molecules were docked into the BG binding pocket, and molecular dynamics simulations with explicit water molecules were carried out. Stabilization energies for the interactions of specific regions of the inhibitor and individual amino acid residues were calculated. The alkyl spacer is located in a cleft along helix 6 of MGMT. With increasing spacer length there is increasing interaction with several amino acid residues which play an important role in the proposed nucleotide flipping mechanism required for DNA repair.

  Production of metallo-β-lactamases (MBLs) in bacterial pathogens is an important cause of resistance to the ‘last-resort’ carbapenem antibiotics. Development of effective MBL inhibitors to reverse carbapenem resistance in Gram-negative bacteria is still needed. We herein report X-ray structure-guided optimization of 1H-imidazole-2-carboxylic acid (ICA) derivatives by considering how to engage with the active-site
