      • Fundamental principles in pharmacology and medicinal chemistry
      • Drug metabolism (processes by which drugs are broken down)
    • Design and Development of New Drugs
      • Steps involved in creating effective therapeutic agents
      • Methodologies to correlate chemical structure with biological activity (QSAR)

    Drug Targets

    • Specific molecules (often proteins like enzymes and receptors) in the body that drugs interact with to produce their effects
    • For example, ibuprofen targeting specific enzymes involved in the inflammatory process

    Basic Concepts in Drug Action

    • Dose-response relationships (increased doses often lead to increased effects)
    • Drug-receptor interactions (drugs binding to receptors to trigger responses)
    • Time course of action (how long a drug remains active in the body)

    Drug Metabolism

    • Process where the body transforms drugs into different chemical forms, facilitating elimination
    • Phase I: Chemical modifications (oxidation)
    • Phase II: Conjugation with other molecules (enhance excretion)
    • Examples include alcohol metabolism (converted to acetaldehyde then acetate)
    • Crucial for drug design to ensure efficacy and safety

    Quantitative Structure-Biological Activity Relationships (QSAR)

    • Predicting biological activity of chemical compounds based on their chemical structure
    • Analyzing existing data on similar compounds to design new drugs with similar or enhanced effects
    • Structural features of a drug affecting its action against specific disease targets (e.g., cancer)

    Defining Drugs

    • Active Pharmaceutical Ingredient (API): The pure substance with therapeutic activity
    • Medicine: Contains one or more APIs and other substances (excipients) for practical use
    • Examples include caffeine, found in coffee and tea
