  • Publication number: 20150141456
    Abstract: The present invention relates to tertiary amines of formula (I) for use in therapy, particularly for use in treating cardiovascular disorders. The compounds have been found to regulate phospholamban phosphorylation by interfering with the A-kinase anchor protein 18delta (AKAP18?) binding to the PKA substrate phospholamban. The compounds share a tri(alkylaryl/alkylheteroaryl) amine structure.

  • Patent number: 9026203
    Abstract: The invention relates to pharmaceutically acceptable salts of amphiphilic photosensitizing agents which have a water solubility of at least 0.5 mg/ml and to their use in methods of photochemical internalization. Such salts may be formed from a pharmaceutically acceptable base, for example an organic amine such as an amino alcohol, or from a pharmaceutically acceptable acid, for example a sulphonic acid or a sulphonic acid derivative. Due to their increased water solubility, such salts are particularly suitable for use in the preparation of parenteral pharmaceutical preparations, e.g. for use as solutions for injection or infusion.
