    Study Notes

    Medicinal/Pharmaceutical Chemistry

    • Involves the discovery, design, development, and characterization of drug substances.
    • Encompasses pharmacological and analytical aspects to evaluate drug efficacy.

    Role of Medicinal Chemists

    • Crucial in drug discovery and preclinical study phases.
    • Engaged in pharmaceutical quality control to ensure drug safety and effectiveness.

    Drug Discovery and Development

    • Definition of a Drug: Compounds interacting with biological systems to elicit a desired response, aimed at preventing or alleviating disease symptoms.
    • Mechanism of Action: Drugs act by binding to specific biological macromolecules at designated sites, termed binding sites, to induce a biological response.

    Key Concepts in Drug Design

    • Lead Identification: The process of selecting potential drug candidates based on their ability to interact effectively with biological targets.
    • Binding Interactions: Essential for the drug's efficacy; involves various types of molecular interactions that determine the strength and specificity of drug action.
    • Receptors as Drug Targets: Proteins or macromolecules that drugs bind to, initiating a biological response, often essential for therapeutic action.

    Additional Concepts

    • Isomers: Different compounds with the same molecular formula but distinct arrangements, affecting drug effectiveness and metabolism.
    • Isosteres: Molecules or ions with similar shapes and electronic properties but different atoms, utilized in drug design to modify activity and reduce side effects.
