Therapeutic Designer Peptide to Combat Acute Heart Muscle Weakness

12. February 2025

Researchers of the Heidelberg University, Heidelberg University Hospital (UKHD) and Heidelberg Institute for Theoretical Studies (HITS) have developed a synthetic peptide based on the natural protein S100A1, a nearly universal “fuel” for weakened hearts. The researchers combined computer-aided methods with lab studies to investigate the therapeutic effect of the so called S100A1ct peptide molecule. The results have been published in the journal “Circulation”.

The “Molecular and Cellular Modeling” group led by Rebecca Wade was part of the project. The approach was to integrate experiments on heart muscle cells and animals and computational molecular modeling. “Our lab developed a customized computer-aided modeling pipeline for this project to model the molecular structure of the peptide and interactions with the predicted molecular effectors in the diseased heart cells”, Wade says. “The computational modeling guided the design of specific experiments to investigate the molecular mechanisms.”

The framework for the successful cooperation was provided by the Informatics for Life (I4L) Initiative, which was funded by the Klaus Tschira Foundation. The project received further financial support from the German Center for Cardiovascular Research with translational project funding from the Federal Ministry of Education and Research from the “Preclinical Confirmatory Studies” program.

About HITS

HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
