1. Structure and Activity of Circular Plant Proteins : Cytotoxic Effects of Viola Cyclotides
Abstract : Cyclotides are a family of small and macrocyclic proteins that have been found in Violacaee and Rubiaceae plant species. These proteins contain a cystine knot: two disulfides bonds together with their connecting peptide backbone form an embedded ring which is penetrated by a third disulfide bond. READ MORE

2. Cyclotides : Tuning Parameters Toward Their Use in Drug Design
Abstract : Cyclotides are plant proteins with a unique topology, defined as the cyclic cystine knot motif. The motif endows cyclotides with exceptional chemical and biological stability. They also exhibit a wide range of biological activities including insecticidal, cytotoxic, anti-HIV and antimicrobial effects. READ MORE

3. Cytotoxic Cyclotides : Structure, Activity, and Mode of Action
Abstract : Cyclotides are small cyclic plant proteins, and this thesis addresses their cytotoxic structure-activity properties and their mode of action on human cancer cell lines. Cyclotides were isolated from Viola odorata and Viola tricolor; three novel cyclotide sequences and two known sequences, but of new origin, were identified using mass spectrometry, amino acid analysis, and Edman degradation.

4. Interaction of cyclotides and bacteria : A study of the cyclotide action and the bacterial reaction
Abstract : The growing problem of antibiotic resistance and the lack of promising prospective antibiotics have forced us to search for new classes of antibiotics. Among the candidates to develop into future antibacterials are antimicrobial peptides (AMPs). READ MORE
