Polaris Quantum Biotech (PolarisQB), the leader in quantum computing-based drug design, announced the development of Quantum-Aided Drug Design (QuADD) for molecular library optimization in April 2023. QuADD runs on quantum computers that solve problems with unprecedented speed and power, allowing users to search a chemical space of more than 1030 molecules for those that complement their specific binding pocket. This Software-as-a-Service platform builds custom, enriched molecular libraries, and it is currently available to customers. As a part of a series of white papers detailing how QuADD works, PolarisQB released a white paper concerning Best-in-Class mode. This new feature identifies novel molecules that are just outside the published intellectual property of a given template ligand.
The white paper reports the results for the test case of sorafenib in complex with p38 MAP kinase. QuADD’s Best-In-Class mode was able to generate a library of molecules with optimal drug-like properties and similar binding profiles as the template but with distinct structural characteristics that maintain an appropriate degree of diversity. With this approach, Best-In-Class mode is ideal for searches in the periphery of intellectual property. Dr. Kendall Byler, Director of Computational Chemistry for PolarisQB, said, “Best-In-Class allows QuADD to examine areas very close to a known drug patent by searching an enormous chemical space and recovering subtly novel structures that still resemble the template.”
