Study Notes
Virtual Screening Techniques
- Virtual screening enables the rapid selection of biologically active compounds from larger collections.
- Methods include structure-based and ligand-based approaches, alongside other methods.
- Structure-based methods utilize the three-dimensional structure of protein targets to assess binding affinities.
Structure-Based Methods
- Two main approaches: receptor docking and de novo design.
- Receptor docking predicts how a molecule binds in the active site and its binding affinity.
- De novo design creates novel molecules tailored to fit specific active sites and biological activities.
Applications in Antibiotics
- Virtual screening can help redesign existing antibiotics and develop new ones.
- Example: Quinazoline inhibitors targeting DNA gyrase to tackle bacterial resistance.
Case Studies on Antibiotics Optimization
- Case Study 1: Utilized Lipid Maps and LipidBlast for lipid analysis, enhancing mass spectrometry searches.
- Case Study 2: Applied machine learning to predict chemical compounds based on lipidomic data related to diseases, with ongoing software development.
- Case Study 3: The Scripps Research Institute developed a high-throughput robotic platform for efficient bacterial and fungal culturing.
Machine Learning in Antibiotic Resistance
