Competence Center for Drug Discovery

The Competence Center for Drug Discovery (CC Drug Discovery) is dedicated to the discovery and development of new drugs for innovative therapies against serious diseases.

Translational drug discovery
The Competence Center for Drug Discovery at the ZHAW works on a national and international level with partners from industry and academia to develop new clinical drug candidates. Our mission is to address therapeutic issues in an interdisciplinary environment and to promote the synergy of biological, chemical and medical expertise. Our core competence in medicinal chemistry enables us to work with our partners on a range of indications (e.g. cancer, infectious diseases, metabolic diseases) for the benefit of patients.
2nd edition "Competencies in Drug Discovery"
The second edition of our symposium “Competencies in Drug Discovery”, brought together 160 international experts from industry and academia, providing both experienced scientists and young researchers with the opportunity for fruitful exchanges and discussions on the future of drug discovery.

1st edition "Competencies in Drug Discovery"
In June 2022, the first symposium “Competencies in Drug Discovery" took place at the ZHAW Wädenswil. During the symposium, projects from various therapeutic indications were discussed in an interdisciplinary environment to promote the synergy of biological, chemical and medical competencies.

Therapy for the NRAS melanoma subtype
Melanoma is the fifth most common cancer in Switzerland and the most lethal skin cancer. NRAS (neuroblastoma ras viral oncogene homolog)-mutated melanoma is the most aggressive subtype, with no effective therapy after immunotherapy failure. The goal of this project is to develop the first effective…

Inhibitors targeting SARS-CoV-2 proteases
So far, vaccines are available to combat the Covid-19 pandemic, which can protect against a severe course, although part of society also does not want to be vaccinated or cannot do so due to pre-existing conditions. With a drug that can fight the virus in the organism, infected patients with severe…

Developing novel and effective therapies for treatment of childhood brain cancers
Brain cancers are a leading cause of mortality in children. Brainstem glioma constitutes 10% of all pediatric central nervous system tumors, the most common type being a high grade diffuse midline glioma (DMG). Preclinical discoveries fail to translate into clinical success due to: i) drug systemic…
