Abstract: The present invention provides a modified lactoferrin peptide which is cytotoxic, 7 to 25 amino acids in length, with three or more cationic residues and which has one or more extra bulky and lipophilic amino acids as compared to the native lactoferrin sequence, as well as esters, amides, salts and cyclic derivatives thereof as well as methods of preparing such peptides, pharmaceutical compositions containing such peptides and use of the peptides as medicaments, particularly as antibacterials or anti-tumoural agents.

Abstract: The present invention relates to a method of separating a first solute A and a second solute B using (simulated) moving bed chromatography. According to the present invention at least one of a) a feed stream; and b) a desorbent stream comprises an organic solvent. The use of different solvent liquids for the feedstream and the desorbent stream results in an increased difference in partition coefficients for solute A and solute B. According to the present invention it is possible to obtain solute A in an extract stream in a form which is more concentrated in comparison to the concentration of solute A in the feedstream.
