Penn Engineers have developed PeptiVerse, an AI-powered platform that predicts key chemical and biological properties of peptides, the strings of amino acids whose medical potential has been demonstrated by the success of GLP-1 drugs, the widely used weight-loss treatments.

In Nature Communications, the researchers describe how they trained PeptiVerse using a wide range of data sets, allowing it to predict properties that can help determine whether a peptide is worth pursuing as a potential drug, such as the peptide’s likelihood of dissolving, entering cells, avoiding toxicity and lasting long enough in the body to have an effect.

While tools for predicting such properties exist, those tools often focus on a narrower set of traits or only one kind of peptide. PeptiVerse, by contrast, brings many of those predictions together in one open-source, easily accessible platform, allowing users to evaluate both ordinary peptides and chemically modified versions designed to work better as drugs.
