Products Product structure-based drug design
  Product 2 cryogenic transmission electron microscopy (cryoEM, Cryo-EM)
Index term Index term Otsuka–LeadXPro: structure-based drug discovery, 201906– collab strategic on membrane protein structure research of Astex + LeadXPro

leadXpro AG announced today an agreement with Astex Pharmaceuticals to facilitate structure-based drug discovery of membrane protein targets by single particle cryo-Electron Microscopy (cryo-EM).

leadXpro and Astex will work on high resolution membrane protein cryo-EM structures to enable characterization of small molecules binding to drug targets. This information may facilitate the discovery and subsequent optimization of lead molecules.

Nicolas Bocquet, project leader at leadXpro said: “With the recent developments and improvements of this technology, we’re confident of the utility of cryo-EM derived structural information in small molecule drug design projects on targets which were previously not accessible to X-ray crystallography.”

Pamela Williams, project leader at Astex said: “X-ray crystallography has always been the cornerstone of Astex’ drug discovery platform starting from fragment molecules to clinical candidates. We hope that Cryo-EM will complement our efforts in structure-based lead discovery and extend the target space to include membrane proteins.”
