Novel antibiotic chemistries: aminoglycoside-based cationic amphiphiles

Description:

The antibiotics markets: The total world market is in the range of $25 billion a year and it is growing, at a time when the antibiotics pipeline is “bone dry”.

 

The Schwiezer/Zhanel technology offers an important new opportunity with the aminoglycoside molecules; a class well established for its effectiveness and well understood safety profile.

 

Aminoglycosides constitute a large family of clinically important antibiotics They have broad spectrum activity against most Gram-negative and Gram-positive bacteria and have proven useful over decades. Although they exhibit potent bactericidal activity, their widespread use has been compromised by dose related toxicity and the emergence of aminoglycoside-resistant strains. Efforts to develop novel, active and less toxic aminoglycosides or modified analogues have been slow because they are difficult to chemically modify.

 

The Technology: provides a series of patented chemical modifications and conjugates. These are shown to be active in clinically important bacterial strains:

 

   Composition of matter patents: special aminoglycoside – lipid and aminoglycoside-ultra short
   peptide conjugates

 

   Practical methods of synthesis, cost effective and strong intellectual property “space”.

 

   In vitro data on effectiveness with important bacterial strains, MRSA and Pseudomonas.spp.

 

   Good in vitro toxicity profiles
