Rapid access to detailed structural information about drug targets and bound ligands is significant in the identification and optimization of lead compounds. The structural information of the protein-ligand complex can accelerate the optimization process of potential lead compounds and help to solve problems related to compound selectivity, pharmacokinetics, as well as patentability. X-ray crystallography has always been a major technology to provide high-resolution protein- ligand complex structures for the pharmaceutical industry.

For any project that involves determining the structure of biological macromolecules, Creative Biostructure can provide flexible MagHelix™ Gene-to-Protein and Gene-to-Structure solutions. The steps of obtaining structures of protein-ligand complexes by X-ray crystallography include construct design and cloning, protein expression and purification, protein-ligand complex crystallization and crystal optimization, collection and processing of diffraction data, and refinement of the structure for several or dozens of target-ligand complexes.

Co-crystallization Compared with soaking, protein-ligand co-crystallization usually requires more resources and time. However, it is often the best option when obvious conformational changes or crystal packing preclude other approaches. The requirement to optimize crystals for each complex makes this method resource- and time-intensive. Sometimes, the size or the chemical properties of the ligand may even require screening for new crystallization conditions.

Capabilities and advantages of our MagHelix™ Co-crystallization and Soaking services:

• Automated and robotic technologies have been applied at different aspects of the gene- to-structure path, greatly reducing the time needed to obtain structural information for lead optimization. Our high-throughput crystallography technique has been successfully utilized for fragment-based screening.
• Our soaking and co-crystallization approaches can directly validate the hit compounds obtained during the screening process.
• The protein-fragment crystal structure can identify the binding mode of a fragment, which is helpful to guide fragment evolution.
• We have some ready-made drug target crystals that can be directly used for soaking.
• Our structural biology techniques can offer information throughout the lead identification and optimization process.
• Our multi-disciplinary drug discovery team will provide you with insightful suggestions.
