Patent number: 11154589Abstract: This invention relates to compositions including antibacterial compounds. The invention also relates to the use of the compositions in methods of treating bacterial infections. In one aspect the present invention also provides a method of increasing the susceptibility of bacteria to the anti-bacterial activity of a compound, the method comprising contacting the bacteria with a star shaped peptide polymer of the invention, thereby increasing the susceptibility of the bacteria to the anti-bacterial activity of the compound. Preferably, the method further includes the step of contacting the bacteria with the compound for which the bacteria have increased susceptibility to. The invention is further relates to the combination of a star shaped peptide polymer and an anti-bacterial compound that restore the sensitivity of antibiotic resistant bacteria to antibiotics that are otherwise ineffective when administered alone.Type: GrantFiled: November 2, 2017Date of Patent: October 26, 2021Assignee: The University of MelbourneInventors: Greg GuangHua Qiao, Neil Martin O'Brien-Simpson, Shu Jie Lam, Eric Charles Reynolds
