Abstract: The present invention relates to the cyclic peptides that are agonists of the angiotensin II type 2 receptor (hereinafter the AT2 receptor) useful in the treatment of different types of solid cancer, in particular brain, colon, lung and ovarian cancer. The invention further relates to pharmaceutical compositions containing them and uses thereof for the treatment of cancer.

Abstract: The invention generally relates to the field of medicine and pharmacology. More particularly, it relates to novel analogs of galanin, and the use thereof in therapy. Provided is a cyclic peptide analog of galanin, wherein the galanin analog comprises a (methyl)Lanthionine bridge and wherein the analog has the general formula “X1-X2-X3-X4-X5-X6-X7-X8-X9-X10-X11-X12-X13-X14-X15-X16-X17-X18-X19-X20-X21-X22-”, or a truncated variant thereof lacking X1 and/or up to 11 of the C-terminal residues, wherein two residues selected from the group consisting of X3, X4, X6, X7, X10 and X13-X19 together form a Lanthionine bridge of the structure Ala-S-Ala, or a methylLanthionine bridge of the structure Abu-S-Ala or Ala-S-Abu.

Abstract: The invention relates to analogs of angiotensins, in particular to cyclised analogs having Ang(1-8) agonistic or antagonistic activity and to cyclised Ang(1-7) analogs with agonistic or antagonistic activity and displaying improved proteolytic resistance compared to their linear counterparts. Provided is a cyclic angiotensin peptide analog comprising a thioether-bridge linkage between the amino acids corresponding to positions Tyr4 and Pro7 in naturally occurring Angiotensin. Also provided is the use of analogs in therapy, for example hypertension.

Abstract: The invention relates to the production of heterologous polypeptides in a recombinant host cell. More specifically, it relates to the production and secretion of peptides, such as biologically active peptides, that are modified by one or more lantibiotic-synthesizing enzymes. Provided is a nucleic acid construct encoding a polypeptide comprising 1) a non-lantibiotic export signal that is recognized by a non-lantibiotic export system; 2) a lantibiotic leader peptide that is recognized by at least a lantibiotic dehydratase such as LanB and, C-terminally of said export signal and said leader peptide, 3) a peptide of interest containing one or more serine or threonine residue(s) which can be posttranslationally dehydrated by said dehydratase.

Abstract: Described are novel ways of introducing an affinity tag into a protein of interest. Provided is an enzymatic method for providing a proteinaceous substance comprising a polypeptide of interest and a cyclic affinity tag, comprising: (a) providing at least one precursor proteinaceous substance, the precursor comprising the protein of interest and at least one motif of the general formula X1-Tag-X2, wherein X1 and X2 represent amino acids whose side chains can be linked enzymatically by a covalent bond; Tag is a short amino acid sequence capable of binding to a binding partner of the tag when cyclized; (b) contacting the precursor with at least one enzyme capable of forming a covalent bond between X1 and X2, thereby introducing an intramolecular ring structure comprising the Tag sequence; and (c) isolating the resulting cyclized proteinaceous substance. Also provided are proteinaceous substances obtainable thereby and the use thereof, for instance, for preparing a peptide library.
