Study Notes
Introduction to Pharmaceutical Inorganic Chemistry
- Pharmaceutical inorganic chemistry focuses on designing, synthesizing, and characterizing inorganic compounds for medical use.
- Applications include drugs, diagnostics, drug delivery systems, and imaging agents.
Key Concepts and Applications
- Metal Complexes as Drugs: Transition metal complexes often exhibit potent biological activity due to their ability to bind specific biomolecules.
- Examples: Cisplatin, a platinum-based complex, is a widely used anticancer drug, inhibiting DNA replication.
- Mechanism of Action: Coordination with biomolecules like DNA modifies their structure or function.
- Targeted Drug Delivery: Inorganic materials can be designed for targeted delivery to diseased tissues.
- Drug Delivery Systems: Inorganic nanoparticles (liposomes, polymeric micelles) enhance drug delivery, minimizing side effects.
Diagnostic Agents
- Radiopharmaceuticals: Inorganic compounds with radioactive isotopes are used for disease diagnosis via imaging.
- Examples: Technetium-99m is crucial in nuclear medicine.
- Image contrast agents: Certain inorganic compounds enhance X-ray or MRI images for better tissue/organ visualization.
General Inorganic Chemistry Principles
- Coordination Chemistry: Understanding the formation, structure, and properties of coordination compounds is vital, as many active pharmaceutical ingredients (APIs) are metal complexes.
- Stereochemistry: The spatial arrangement of atoms in metal complexes influences biological activity.
- Spectroscopic Techniques: UV-Vis, IR, NMR, and X-ray crystallography characterize inorganic compounds' structure and properties.
