What is ScreeningAssistant ?

ScreeningAssistant is a software developed at the laboratory of chemoinformatics (Group Leader: Pr. Luc Morin-Allory), ICOA UMR CNRS 6005. It is designed to manage chemical databases. Furthermore the software allows to select a set of compounds for screening tests (High Throughput Screening or Virtual Screening).
SDFiles of chemical compound providers can be inserted in a database. Drug-like properties are computed at the insertion of the molecules. Compounds predicted as non-Drug-like are highlighted. An unique code (IUPAC Chemical Identifier) is also computed for each molecule. With this codes doubloons are removed from the database. An ouput SDFile can be created with molecules which fit the chosen criterias (Lead-like, Drug-like, MW, logP, numbers of H acceptors, number of rotatable bonds...).

Selection of molecules by diversity will be possible. Diversity is very important in the design of screening compound set. In HTS it allows to buy the most representative products of available chemicals.
We are also working in ADME models (Caco-2, solubility and Blood-Brain Barrier permeation). Thes models are designed with MOE descriptors. But we hope we can compute this descriptors with free code, and implement them in ScreeningAssistant.

Aim

  • Create a free tool to build a chemical databases from several SDF and to select compounds for Virtual or High Throughput Screening 

Features

  • Manage chemical databases using a Database Server
  • Combine databases without duplicate structures
  • Analyse the databases
  • Identify reactivecompounds, warheads or "promiscuous aggregating inhibitors"
  • Detect privileged structures
  • Estimate "druglikeness" and "leadlikeness"
  • Allow to select compounds for screening tests
  • Select compounds by diversity and frameworks
