Definition of Medicinal Chemistry

Medicinal Chemistry is the interdisciplinary field of science that focuses on the design, synthesis, and development of pharmaceutical agents or drugs. It combines principles of chemistry, biology, pharmacology, and computational sciences to identify and optimize compounds for therapeutic use.

Branches of Medicinal Chemistry

• Synthetic Medicinal Chemistry

Concentrates on the chemical synthesis of novel molecules with potential medicinal use.

• Pharmacological Chemistry

Studies the interaction of drugs with biological targets to understand their mechanism of action.

• Computational Medicinal Chemistry

Uses computational tools, such as molecular modeling and QSAR (Quantitative Structure-Activity Relationship), to design and predict drug activity.

• Natural Product Chemistry

Look for lead compounds in nature, such as plants, microorganisms, and marine life.

• Analytical Medicinal Chemistry

Analyses and characterises pharmaceuticals and their metabolites to guarantee purity, quality, and stability.

• Biophysical Chemistry

The utilisation of methods such as X-ray crystallography and spectroscopy to examine drug-receptor interactions is the primary focus.

Applications of Medicinal Chemistry
