DeNViS

Virtual Screening as a Service (VSaaS).

Ultra-fast deep learning in silico screening for >1 Billion compounds against any target protein with minimal resources.

We strive to address one of the world’s most complex problems: drug discovery.

New drug development cost: $2.6 billion. Success rate: below 10%.

One of the first phases of drug discovery for a chosen target concerns high-throughput screening. Machine learning has the potential to substantially accelerate the drug discovery lifecycle by performing virtual screening of large databases of candidate drug molecules against a specific target a protein associated with some known disease. At the same time current approaches for structure-based virtual screening are slow.

 

drug design

Accurate and ultra-fast.

We leverage the power of DL,  avoid physics-based simulations, and  achieve state-of-the-art performance with orders of magnitude faster screening times: 10^4 times faster compared to competitors like VINA, GNINA. This renders our approach suitable for virtually screening of vast compound databases, scaling up to billions of molecules per day.

Methodology

DeNViS is based on state-of-the-art machine learning and geometric deep learning technologies:

  1. Geometric deep learning algorithmic backbone with Graph Neural Networks (GNNs)
  2. 3D protein-surface and molecular-graph modelling for the ligand  with chemical & geometric features
  3. Multi-modal fusion of such multiple representations levels to predict a binding affinity score. 
  4. Ensembling multiple models for the final binding affinity prediction.

We evaluated DeNViS in multiple benchmark datasets with impressive results.

More information to be published soon.

VALUE PROPOSITION

Our unique proposition is a Virtual Screening as a Service (VSaaS) solution. 

We propose a service for fast virtual screening, suitable for massive databases with minimal requirements.

DeNViS can be employed for tasks within early-stage drug discovery: drug repurposing, repositioning and potentially other applications within the drug discovery pipeline.

“Deeplab’s tech and outputs ranked among the top-20 worldwide"

In JEDI Grand Challenge we virtually screened 1 Billion molecules against 3 proteins of Sars-Cov2. Currently our submission is evaluated in the wet-lab together with the top-20, out of ~138 teams.

Stand-by for upcoming results which are to be published soon !
