Potential scorpionate antibiotics: targeted hydrolysis of lipid II containing model membranes by vancomycin-TACzyme conjugates and modulation of their antibacterial activity by Zn-ions

Bioorg Med Chem Lett. 2009 Jul 15;19(14):3721-4. doi: 10.1016/j.bmcl.2009.05.064. Epub 2009 May 24.

Abstract

The antibiotic vancomycin-that binds lipid II in the bacterial cell membrane-was conjugated to a mono- and tetravalent mimic of the tris-histidine catalytic triad of metalloenzymes. Targeted hydrolysis by the conjugate was observed using model membranes containing lipid II, and in vitro MIC-values of the targeted mimic constructs could be modulated by Zn-ions.
