Biological Barriers and Drug Delivery

While considering the confusing flood of drugs in the pharmacies it is hard to believe in a lack of medication. But there are still many infectious diseases and also cancer that cannot be treated sufficiently. During a medical treatment it is essential that the drug arrives at the envisaged body region. Read more about the research of the department “Biological Barriers and Drug Delivery” on techniques for the correct distribution of novel drugs. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS).

    Resistance to antibiotics has become one of the major global challenges regarding infectious diseases. This is specifically the issue that is being tackled by the new Helmholtz-Institute for Pharmaceutical Research Saarland (HIPS).

  • 1 cure for ALL viruses? 6 new research teams in the challenge by the Federal Agency for Disruptive Innovations [Video in German]

    Six research teams have entered the second phase of the SPRIND Challenge "A Quantum Leap for New Antiviral Agents" with their approach to developing new antiviral agents. Scientists from the Helmholtz Centre for Infection Research are involved in three of the funded projects. YouTuber Jacob Beautemps introduces the teams.

  • Kleine Teile – große Wirkung: Pharmazeuten des HIPS schleusen Medikamente zielsicher durch den Körper Wie kommt ein Medikament dahin, wo es wirken soll? Das ist eine der zentralen Fragen bei der Entwicklung neuer Wirkstoffe. Denn es reicht nicht, ein tolles neues Medikament gegen Darminfektionen im Reagenzglas zu haben – es muss auch dort hin gelangen, wo die Krankheit stattfindet. Mit Transportmolekülen schleusen die Pharmazeuten des HZI diese Wirkstoffe durch unseren Körper – über Barrieren, durch passende Lücken und an gefährlichen Stellen vorbei.
