  Efforts toward broadening the spectrum of arylomycin antibiotic activity

  摘要：

  New antibiotics are needed, and one source may be 'latent' antibiotics, natural products whose once broad-spectrum activity is currently limited by the evolution of resistance in nature. We have identified a potential class of latent antibiotics, the arylomycins, which are lipopeptides with a C-terminal macrocycle that target signal peptidase and whose spectrum is limited by a resistance-conferring mutation in many bacteria. Herein, we report the synthesis and evaluation of several arylomycin derivatives, and demonstrate that both C-terminal homologation with a glycyl aldehyde and addition of a positive charge to the macrocycle increase the activity and spectrum of the arylomycin scaffold.

  Provided herein are antibacterial compounds, wherein the compounds in some embodiments have broad spectrum bioactivity. The compounds provided herein can in other embodiments overcome the resistance conferred by single amino acid mutations at defined positions of bacterial Signal Peptidases (SPases) and in other embodiments provide for a broader spectrum of antibiotic bioactivity compared to the natural product. Pharmaceutical compositions and methods for treatment using the compounds described herein are also provided.
