Abstract: Heparin derivatives are disclosed that may be used to inhibit formation of metastases. One series of heparin derivatives of the invention are N-acylated with monocarboxylic acids or dicarboxylic acids and have molecular weights from about 1000 Daltons to about 30,000 Daltons. Another series of heparin derivatives of the invention have average molecular weights ranging from about 1000 to 3000 daltons, and are optionally N-acylated with residues from aliphatic monocarboxylic or dicarboxylic acids.

Abstract: Oligopeptides derived from fragments of C-reactive proteins and their use as immunomodulating agents in the therapy of cardiovascular and inflammatory diseases.

Abstract: Peptides endowed with antiinflammatory activity consisting of 25 aminoacids having a sequence with an homology of at least 25% with the 1-25 fragment of the 10 Kda heat shock protein from Mycobacterium tuberculosis.

Abstract: Diesters of carbonic acid disubstituted with primary, secondary or tertiary amine groups, pharmaceutically acceptable salts thereof, and their use as antiviral and inti-inflammatory agents.

Abstract: Heparin derivatives are disclosed which may be used to inhibit formation of metastases. The heparin derivatives of the invention are N-acylated with mono- or dicarboxylic acids, have a molecular weight from about 1,000 to about 30,000 Daltons, and have at least one unit of an open D- or L-iduronic acid.

Abstract: This invention refers to DNA sequences coding for proteins present in the plant Dianthus caryophyllus, to expression vectors containing said sequences and to hosts transformed by said vectors.
