Abstract: The present invention is directed to the use of the peptide compound Gly-Leu-Ser-Lys-Gly-Cys-Phe-Gly-Leu-Lys-Leu-Asp-Arg-Ile-Gly-Ser-Met-Ser-Gly-Leu-Gly-Cys-OH as a therapeutic agent for the prophylaxis and/or treatment of cancer, autoimmune diseases, fibrotic diseases, inflammatory diseases, neurodegenerative diseases, infectious diseases, lung diseases, heart and vascular diseases and metabolic diseases. Moreover the present invention relates to pharmaceutical compositions preferably in form of a lyophilisate or liquide buffer solution or artificial mother milk formulation or mother milk substitute containing the peptide Gly-Leu-Ser-Lys-Gly-Cys-Phe-Gly-Leu-Lys-Leu-Asp-Arg-Ile-Gly-Ser-Met-Ser-Gly-Leu-Gly-Cys-OH optionally together with at least one pharmaceutically acceptable carrier, cryoprotectant, lyoprotectant, excipient and/or diluent.

Abstract: A novel peptides are complexed with HIV-I envelope protein gp120, and causes the protein to assume a CD4i conformation but without occluding the CD4 binding-site of gp120. This peptide-gp120 complex is immunogenic and, upon immunization of subjects, induces broadly-neutralizing antibodies directed to the CD4 binding site of gp120. The peptide preferably consists of a sequence of 8-20 amino acid residues which comprises (a) a core sequence Arg-Xaa1-Asp-Leu-Pro-Xaa2-Trp-Ala (SEQ ID NO: 1) in which Xaa1 and Xaa2 is any amino acid, or (b) certain substitution variants of SEQ ID NO:1.

Abstract: The invention relates to compositions comprising a compound based on the general formula (I) R1-Arg-R2—NH—CH(R3)—CH2—NH—R4??(I) The composition may be used to eliminate and/or reduce microorganisms such as bacteria, viruses, fungi and protozoa.
