  DNA Binding Ligands Targeting Drug-Resistant Bacteria:  Structure, Activity, and Pharmacology

  摘要：

  We describe the lead optimization and structure-activity relationship of DNA minor-groove binding ligands, a novel class of antibacterial molecules. These compounds have been shown to target A/T-rich sites within the bacterial genome and, as a result, inhibit DNA replication and RNA transcription. The optimization was focused on N-terminal aromatic heterocycles and C-terminal amines and resulted in compounds with improved in vivo tolerability and excellent in vitro antibacterial potency (MIC greater than or equal to 0.031 mug/mL) against a broad range of Grainpositive pathogens, including drug-resistant strains such as methicillin-resistant Stapylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae (PRSP), and vancomycin-resistant Enterococcus faecalis (VRE). In a first proof-of-concept study, a selected compound (35) showed in vivo efficacy in a mouse peritonitis model against methicillin-sensitive S. aureus infection with an ED50 value of 30 mg/kg.

• Palladium-Catalyzed Domino C–S Coupling/Carbonylation Reactions: An Efficient Synthesis of 2-Carbonylbenzo[<i>b</i>]thiophene Derivatives
  作者：Fanlong Zeng、Howard Alper

  DOI：10.1021/ol200880m

  日期：2011.6.3

  A facile and selective palladium-catalyzed domino procedure has been developed for the preparation of 2-carbonylbenzo[b]thiophene derivatives from 2-gem-dihalovinylthiophenols. This protocol involves intramolecular C–S coupling/intermolecular carbonylation cascade sequences and allows access to various highly functionalized benzo[b]thiophenes in moderate yields.
