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

Between 2016-2017, 2.8 million UTI diagnoses in the UK, with 24% involving resistant antibiotic prescriptions.
Predictive models were developed using patient data from over 3,000 GP practices, identifying antibiotic resistance likelihood.
Public Health data indicated a 20% resistance rate for first-line antibiotics.

Genomic Data for New Drug Targets

Low-cost genomic sequencing aids in identifying new antibiotic drug targets.
The European Community's EUROPathoGenomics focuses on determinants impacting pathogen-host interactions.
