Investigation of biological systems using

chemical tools

MISSION

EU-OPENSCREEN’s objective is the development of novel research

‘tool’ compounds for all fields of the Life Sciences.

Tool compounds enable researchers to investigate molecular mechanisms of physiological

and pathological processes, many of which can only be studied with these chemical ‘tools’.

Chemical tools complement methods of molecular biology, such as mutagenesis or RNA

interference.

All generated tools and data will be made publically available to the scientific community.

EU-OPENSCREEN – Executive Summary February 2013 Page 16

Chemical compounds, such as this

small molecule, can bind to cellular

structures (e.g. proteins) and modulate

their functions.

Chemical Biology Platform

@ Biotechnology Centre

Platform overview

The Chemical Biology High Throughput Screening platform was

established in 2008 as a service based facility

Permanent staff with continuous, solid competence in the field of chemical biology including HTS, assay development and robotics/automatisation

The facility is equipped with state-of-the-art automated screening instrumentation designed for Chemical Biology screening and to be used for both biochemical and cell based screening activities

The platform is part of the EU-OPENSCREEN, the European

Infrastructure of Open Screening Platforms for Chemical Biology

Strong Nordic collaboration

Lopac and Prestwick: New uses for existing drugs

Used for

• Assay validation

• Hit finding

• Drug repositioning

• Drug sensitivity screen

• Start of new optimization program

New or additional value is generated from a drug by targeting diseases other than those for which it was originally intended.

Targeting protein protein interactions (PPI)

• Contact surfaces of PPI are mostly large and flat -contain no well defined pockets for binding of small molecules.

• Hotspots – subsets of residues that contribute most of the free energy upon binding to a protein partner or a small moelcule

• Many PPI recognise an α-helix – develop small molecules with helical mimetic scaffolds

• Generally PPI inhibitors tend to be larger in Mw and more rigid than a "typical drug"

Assay development

• Large amount of soluble recombinant protein with different tags

• Test different protein combinations, swap tags

• Obtain a robust assay with robust signal to background ratios

• Titre down bead amount and volume to reduce costs

• Transfer the bench top assay to the automated liquid handling platform
