Abstract: The present invention is directed to a pharmaceutical composition including (eg for use as an adjuvant) a polymeric carrier cargo complex, comprising as a carrier a polymeric carrier formed by disulfide-crosslinked cationic components and as a cargo at least one nucleic acid (molecule) and at least one antigen associated with a tumour or cancer disease selected from; an idiotype immunoglobulin (e.g. an idiotype antibody or an idiotype B cell receptor); or at least one idiotype T cell receptor, or in each case a fragment, variant and/or derivative thereof. The inventive pharmaceutical composition allows for efficient induction of an adaptive immune response directed against the idiotype immunoglobulin or T cell receptor, particularly of a Th1-shiftet immune response.

Abstract: The Benzofuranyl- and -thiophenyl-alkane-carboxylic acid derivatives are prepared Tby cyclisation of hydroxy acetophenones and related compounds or by Wittig-reaction of benzofuranyl aldehydes. The compounds can be used to prepared medicaments.
