QuantumBio, Inc. develops, licenses, and customizes computer-assisted molecular modeling and computer-assisted drug design solutions for pharmaceutical, biotechnology, and life science research organizations. The firm's DivCon Discovery Suite is built on cutting-edge technology utilizing fast, high-performance linear scaling, quantum mechanical algorithms in a user-friendly format. These technologies have been used in Computational Chemistry, X-ray Crystallography, and Nuclear Magnetic resonance to better understand interaction energies, to determine ligand and fragment binding modes, to crystallographically refine X-ray structures leading to experimental structures with lower strain, and to determine ligand and active site protonation states. With these tools, even lower resolution crystal structures become more useful for drug design campaigns.
