Introduction to Drug Design explains the process of discovering and developing new drugs based on target identification and optimization.
Introduction to Drug Design
- Drug design involves discovering or creating therapeutic agents based on a biological target.
- It combines chemistry, biology, pharmacology, and computational science to develop safe and effective drugs.
Key Aspects
- Target Identification: Selecting a biological molecule for therapeutic modulation.
- Lead Discovery: Identifying active compounds from natural sources, screening, or rational design.
- Lead Optimization: Enhancing potency, selectivity, and pharmacokinetics (ADME).
- Preclinical & Clinical Testing: Assessing efficacy and safety in biological systems and humans.
Rational Drug Design
- Traditional drug discovery relied on trial-and-error screening of large chemical libraries.
- Modern rational drug design leverages:
- Molecular target structures (e.g., proteins),
- Structure–activity relationships (SAR) of known ligands,
- Computational modeling (e.g., docking, virtual screening),
- Physicochemical properties affecting bioavailability and safety.
