About Cocrystal Pharma’s Structure-Based Drug Discovery Platform
Cocrystal Pharma is leveraging its structure based drug discovery platform technology to design next generation antiviral candidates that precisely target viral replication mechanisms. By binding to highly conserved regions of viral enzymes, the Company’s compounds aim to maintain potency against mutating strains while minimizing off target effects, offering potentially safer, broad spectrum antiviral solutions. This approach streamlines candidate identification and optimization, enabling more rapid progression of promising therapies with robust resistance and safety profiles.
The Company’s platform provides a three dimensional structure of inhibitor complexes at near-atomic resolution, providing immediate insight to guide Structure Activity Relationships. This helps identify novel binding sites and enables a rapid turnaround of structural information through highly automated X-ray data processing and refinement. This technology permits the development of novel broad spectrum antivirals.
