Drug discovery

Specialised capabilities for research in drug discovery
Drug Discovery at Sydney Analytical provides specialist support for early-stage drug discovery. This includes capabilities in protein production and characterisation, protein X-ray crystallography and fragment-based drug discovery.

Protein Production and Characterisation (PPC) is a key node that assists researchers with the expression, purification and analysis of their proteins of interest. The facility is open to all researchers and its main objective is to facilitate the production and characterisation of proteins that most often constitute major drug targets. Services include: 

  • undertaking experiments to produce and characterise target proteins in state-of-the-art laboratories
  • providing expert advice to users and training personnel (including students and staff). 

We work with three different expression hosts (bacterial, insect, and mammalian cells), and use highly-specialised protein purification and characterisation equipment. The attached flyer (pdf, 475KB) has more information about the PPC workflow, as well as our equipment and expertise.

Protein X-ray crystallography is one of the most powerful methods to visualise the molecular structure of a protein at atomic resolution. The structure, in turn, provides a better understanding of a protein’s functionally important sites and its mechanism of action.

This facilitates the development of efficient and specifically targeted drugs. Sydney Analytical facilities provide a platform for trained crystallographers to access these state-of-the-art instruments. In addition, our expert staff provide guidance and can assist researchers, especially those new to the field of X-ray crystallography, in determining the three-dimensional structure of their target protein.

Services offered include:

  • protein crystallisation
  • in-house crystal screening
  • data collection at the Australian Synchrotron and data processing
  • structure determination and refinement.

Fragment-based drug discovery (FBDD) is a strategy that is growing rapidly in popularity. Rather than rely on large libraries of complex molecules, FBDD involves a small, carefully curated library of molecules that are about half the size of typical drugs. A drug target is screened against the library and ‘hits’ can then be chemically expanded to create lead compounds that bind with high affinity. The approach can be used to target enzymes as well as less traditional targets such as protein-protein or protein-nucleic acid interactions, and even membrane proteins.

Sydney Analytical use a fragment library curated by the medicinal chemists at the Monash Fragment Platform. Our primary screening methods are Nuclear Magnetic Resonance (NMR) and Surface Plasmon Resonance (SPR). Please see the attached flyers for more information about our FBDD workflow, as well as our equipment and expertise.
