  • Evaluation of the amino acid binding site of Mycobacterium tuberculosis glutamine synthetase for drug discovery
  • 2008
  • Ingår i: Bioorganic & Medicinal Chemistry. - : Elsevier BV. - 0968-0896 .- 1464-3391. ; 16:10, s. 5501-5513

    • A combination of a literature survey, structure-based virtual screening and synthesis of a small library was performed to identify hits to the potential antimycobacterial drug target, glutamine synthetase. The best inhibitor identified from the literature survey was (2S,5R)-2,6-diamino-5-hydroxyhexanoic acid (4, IC(50) of 610+/-15microM). In the virtual screening 46,400 compounds were docked and subjected to a pharmacophore search. Of these compounds, 29 were purchased and tested in a biological assay, allowing three novel inhibitors containing an aromatic scaffold to be identified. Based on one of the hits from the virtual screening a small library of 15 analogues was synthesized producing four compounds that inhibited glutamine synthetase.

  • Microwave-Enhanced Copper-Catalyzed N-Arylation of Free and Protected Amino Acids in Water
  • 2007
  • Ingår i: Journal of combinatorial chemistry. - : American Chemical Society (ACS). - 1520-4766 .- 1520-4774. ; 9:2, s. 204-209
  • Tidskriftsartikel (refereegranskat)abstract
    • A microwave-enhanced copper-catalyzed protocol for N-arylation using water as the solvent is reported. This fast transformation allows the reaction between various amino acids or amino acid esters and a diverse set of substituted aryl bromides in less than 40 min, affording good yields of non-protected N-arylated amino acids with only minor racemization (6% or less). In addition, online ESI-MS and MS/MS analysis were used to "fish-out" an anionic Cu-containing amino acid complex directly from an ongoing N-arylation reaction.
