Knowledge-Based Structure Analysis

Knowledge-Based Structure Analysis for Drug Discovery

PharmAI Discovery’s DiscoveryEngine achieves industry-leading performance in early drug discovery, with 30% hit rates in vitro and 16% in vivo, validated through comprehensive biological testing.

Powered by interpretable AI, deep learning, and structure-based modeling, DiscoveryEngine explores an 80-billion-dimensional chemical-biological search space and screens against over 95% of the human proteome. This enables rapid identification of potent, selective compounds, including those targeting complex challenges like protein–protein interactions.

The platform’s built-in in vitro and in vivo validation loop ensures predictions lead to real biological activity, while its off-target profiling capabilities de-risk candidates early in the pipeline. With a track record of 40+ successful projects, DiscoveryEngine transforms discovery timelines and success rates, from digital screening to preclinical proof.

A Knowledge-Based Approach

A Knowledge-Based Approach

Our disruptive software technology identifies drug candidates based on the geometry of protein binding sites and their drug-target interactions. This method paves new ways to explore the drug-target space at a ground-breaking precision.

  • Predictions based on 3D protein structure & binding affinity data
  • Exploits hidden knowledge in vast numbers of protein-ligand complexes found in the Protein Data Bank (PDB)
  • Delivers high scaffold diversity
  • Off-target identification of up to 95% of the human genome

Case study: binders to cGMPdependent 3',5'-cyclic phosphodiesterase (PDE2)

PharmAI’s DiscoveryEngine scored 125 compounds from a library of 2M compounds, spread across the chemical space. After in vitro validation, seven compounds showed binding to PDE2 (at a hit rate of almost 6%) of which three showed affinities in the lower micromolar range.

State-of-art AI

AI-powered Predictions

Our Artificial Intelligence (AI) initiative opens the door to new compound classes. We use classical AI methods with the combination of Deep Learning to predict binding affinity and to improve the quality of our algorithm’s output.

Our aim is make the discovery of drugs cheaper and quicker while keeping it at a high precision. In addition, we contineously improve our algorithms by combining classical and semi-supervised deep-learning in a smart manner.

What We Deliver

Off-target identification service at an early stage of drug discovery

Case study: Prediction of MAPK14 Off-Targets

Using PharmAI's DiscoveryEngine, 13 off-targets were identified and further validated in the laboratory tests in collaboration with 2bind GmbH.

Of the 13 tested proteins, binding was observed for six which corresponds to an extraordinarily high hit rate of 46 percent.
