Abstract
Novel peptoid oligomers are disclosed that have a formula represented by the following formula I: The peptoids demonstrate antimicrobial activity and may be prepared as pharmaceutical compositions and used for the prevention or treatment of a variety of conditions in mammals including humans where microbial invasion is involved. The present cyclic and linear peptoids are particularly valuable as their effect is rapid, broad in spectrum and mostly indifferent to resistance provoked by standard antibiotics.
Claims29
A method for treating, ameliorating or managing a disease or condition, which comprises administering to a patient in need of such treatment, amelioration or management a therapeutically acceptable amount of a peptoid oligomer according to formula Ib
- a salt, stereoisomers, isotopic variants, or tautomers thereof;
- wherein each R1 is independently substituted or unsubstituted alkyl;
- each R2 is independently hydrogen, or substituted or unsubstituted alkyl;
- or each R1 and R2 are joined together to form a 4-7 membered heterocyclic ring;
- the said peptoid oligomer consists of one or more monomers selected from Nap, Nab, Nah, Ngb, Npm, Nnm, Ndp, Nip, Nib and Pro:
- and
- n is an integer between 4 and 20;
- and at least one of the monomers in the peptoid oligomer is Nap, Nab, Nah, or Ngb.
