Dr John Liebeschuetz

Computational Chemist, Astex Pharmaceuticals

"Mogul is an excellent tool for identifying crystallographic problems with ligands in protein-ligand crystal structures."

Identifying truly unusual geometry in a ligand allows us to design that out, reducing strain and improving potency.

Dr Martin Stahl

Chief Scientific Officer, LifeMine Therapeutics

"The breadth and depth of CSD data is enormous today. It covers a lot of space of interest to medicinal chemistry."

Plus, you know that every structure you see has been derived from experiment. This leads to very high confidence in predictions based on CSD data, whether you predict a conformation or piece together a new structure from components.

Professor Jennifer Swift

Georgetown University

"There's no limit to what you can ask."

The ability of the database to do new and interesting types of queries has a lot of potential — there's no limit to how many questions you could ask.

Dr Gilles Ouvry

VP Chemistry, NRG Therapeutics

"Time and time again, going back to actual conformational data derived from small molecule Xray has helped me interpret structure activity relationships."

In this sense, CCDC is a truly a unique database and softwares such as ConQuest and Mercury have not only been linchpins of my design process but also a constant source of inspiration for years.
