摘要:
The present invention relates to a method for predicting or designing, detecting, and/or verifying a novel cell-penetrating peptide (CPP) and to a method for using said new CPP and/or a novel usage of a known CPP for an improved cellular uptake of a cellular effector, coupled to said CPP. Furthermore, the present invention also relates to a method for predicting or designing, detecting and/or verifying a novel cell-penetrating peptide (CPP) that mimics cellular effector activity and/or inhibits cellular effector activity. The present invention additionally relates to the use of said CPP for treating and/or preventing a medical condition and to the use of said CPP for the manufacture of a pharmaceutical composition for treating a medical condition.
摘要:
Constructs of peptides and nucleic acid analogs conjugated together for transport across a lipid membrane and for delivery into interactive contact with intracellular polynucleotides are disclosed. Transport is effected through at least the exterior membrane of a cell, and most likely also through the walls of subcellular structures separated from the cytosol by lipid membranes, including the nucleus, mitochondria, ribosomes, etc. Peptide nucleic acid (PNA) analog sequences conjugated through a labile disulfide bond to transporting peptides, are intracellulary cleaved, and target mRNA (antigene) or dsDNA (antisense).
摘要:
The present invention relates to a system for intracellular delivery of a cargo comprising at least one component A chosen from aliphatic linear or branched moieties with at least 4 carbon atoms and/or cyclic ring systems comprising 2-4 rings which may contain several hetero atoms chosen from N, S, O and P, wherein component(s) A is (are) attached to a cell penetrating peptide B and/or a non-peptide analogue thereof. It also relates to methods of using the system in diagnosis of diseases, as research tool and as a targeting system, a composition comprising the system and especially a pharmaceutical composition a material covered with the system and a material having the delivery systems into the material. Finally it relates to novel peptides.

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.

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.

摘要:
A galanin antagonist which is a galanin receptor ligand is described. New peptides, Galanin (1-12)-Pro-Substance P(5-11), Galanin (1-12)-Pro-Bradykinin(2-9), Galanin (1-12)-Pro-Pro-Pro- (Leu.sup.5 -Enkephalin (5-1), Galanin (1-12)-Pro-Lys(.epsilon.-NH-)Pro-(Leu5-Enkephalin (5-1) and functional analogues and functional derivatives thereof are disclosed. The peptides are used in pharmaceutical preparations to treat a disorder in a mammal which depends on the physiological function of galanin at the galanin receptor.
