  • Publication number: 20120282225
    Abstract: Viral vectors are potential tools for eliminating the viability of eukaryotic cells in anti-cancer therapies since they can efficiently destroy the cancer cells and trigger an immune response against tumours. Typically viruses are not specific to cancer cells and all methods known in art aiming to the construction of cancer-specific viruses suffer from serious problems. The present invention presents a universal method to overcome these problems and is usable for any DNA virus replicating in nucleus or for any layered vector of RNA viruses. In this method the viral gene expression and/or replication will be blocked by the introduction of one or more aberrantly spliced introns into crucial gene expression units of the virus or vector. Lethal effect of these mutations is reverted in a controlled manner by the delivery of splice-switch oligonucleotide (s) correcting the introduced defects and restoring the biological functionality of the virus or vector, including cytolytic properties.

  • Publication number: 20100279918
    Abstract: A construct comprising a cancer-homing peptide, an optional linker and a cell-penetrating peptide coupled to an anticancer drug and/or a diagnostic agent is disclosed. The homing peptide is for example a linear pentapeptide such as CREKA (SEQ ID NO:1), AREKA (SEQ 5 ID NO: 23) or CREKA0 (SEQ ID NO: 23), or a cyclic nonapeptide CPGPEGAGC (SEQ ID NO:2), and the cell-penetrating peptide is for example one of the peptides SEQ ID NO:3-SEQ ID NO:20. The anticancer drug may be selected from alkylating agents, antimetabolites and cytotoxic antibiotics, and the diagnostic agent may be a fluorescent label. Further, a method of delivering an anticancer drug and/or a diagnostic agent into a cancer cell 0 comprising administration of a construct according to the invention in vivo or in vitro is described.

  • Patent number: 6747060
    Abstract: Compounds which are non-natural galanin receptor ligands are disclosed. The ligands are of small size, have agonist or antagonist galanin activity and may cross the blood-brain barrier to displace galanin from galanin receptors. The ligands are useful as medicaments for treatment of convulsions (e.g. in epilepsy), diseases and disorders related to endocrinology (e.g., growth hormone, insulin or prolactin release), tumors expressing galanin receptors, feeding disorders pain, allodynia, psychiatric disorders such as depression (involving e.g., noradrenaline or serotonin), cognitive disorders (e.g. Alzeimer's disease), and the like.
