Beta-hairpin peptidomimetics of the general formula (I), and pharmaceutically acceptable salts thereof, with P, T, Q., and optionally L being elements as defined in the description and the claims, have Gram-negative antimicrobial activity to e.g. inhibit the growth or to kill microorganisms such as Klebsiellapneumoniae and/or Acinetobacter baumannii and/or Escherichia coli and/or Pseudomonas aeruginosa. They ca n be used as medicaments to treat or prevent infections or as disinfectants for foodstuffs, cosmetics, medicaments or other nutrient-containing materials. These peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.

decarboxylation and deamination to afford showdomcyin after exposure to air. These results suggest that showdomycin could be an artifact due to aerobic isolation; however, the autoxidation may also serve to convert an otherwise inert product of the biosynthetic pathway to an electrophilic C-nucleotide thereby endowing showdomycin with its observed bioactivities.

Novel template-fixed β-hairpin peptidomimetics of the general formula (I) wherein the single elements T or P are α-amino acid residues connected in either direction which, depending on their positions in the chain, are as defined in the description and the claims, and salts thereof, have the property to antagonize the receptor CCR10. They can be used as medicaments to treat or prevent diseases or conditions in the area of dermatological and cutaneous disorders, inflammation, allergic disorders, respiratory diseases, diseases of the gastro-intestinal tract, ophthalmic diseases, haematology and cancer. These β-hairpin peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.
