The invention relates to compounds having a structure according to formula (I), cyclo[(R1)Xaa1-B-(R2)Xaa2-(R3)Xaa3-(R4)Xaa4], or pharmaceutically acceptable salts thereof, wherein Xaa1 and Xaa3 are independently of each other, a natural or unnatural amino acid, preferably with Xaa1 and Xaa3 being, independently of each other, an amino acid comprising an aromatic moiety in its side chain, Xaa2 is a natural or unnatural basic amino acid, Xaa4 is glycine or a D-amino acid, R1, R2, R3 and R4 are independently of each other H or methyl, B is an amino acid group having a structure according to formula (II), -N(-Q)-CHR5-C(=O)-, wherein R5 is selected from the group consisting of H, optionally substituted alkyl, optionally substituted aryl and optionally substituted heteroaryl, and a moiety L, and wherein Q is a group being sterically more demanding than a methyl group. The invention also relates to compositions, methods and uses related to said compounds.
