Novel peptide compounds and pharmaceutical compositions thereof are disclosed that have a formula represented by the following formula (I) wherein L1, L2, L3, Z, R1, R2, R4 and R5 are as described herein. The compounds demonstrate antimicrobial activity and may be prepared as pharmaceutical compositions and used for the prevention and treatment of a variety of conditions in mammals including humans where microbial invasion is involved. The present peptides are particularly valuable as their effect is rapid, broad in spectrum and mostly indifferent to resistance provided by standard antibiotics.
The invention provides a method of treating tumors by adminstering to a human or animal patient an effective amount of a molecule of 2 to 4 amino acids or equivalent subunits in length, which incorporates a bulky and lipophilic group comprising at least 13 non-hydrogen atoms and containing no more than 2 polar functional groups, in which the bulky and lipophilic group incorporates one or more closed rings of 5 or more non-hydrogen atoms, and in which the molecule further has at least two more cationic than anionic moieties.

A series of synthetic antimicrobial peptidomimetics (SAMPs) have been prepared and found to be highly active against several Gram-negative and Gram-positive bacterial strains. These derivatives comprise the minimal structural requirements for cationic antimicrobial peptides and showed high selectivity for Gram-negative and/or Gram-positivebacteria compared to human red blood cells. We have found that
