Medicinal Chemistry is a branch of science that focuses on designing and developing new drugs to treat diseases. It combines principles from chemistry, biology, and pharmacology to create effective medications. Scientists in this field study how different chemical compounds interact with biological systems, aiming to improve the safety and efficacy of treatments. The process often involves synthesizing new molecules and testing them for their ability to target specific disease pathways. By understanding how drugs work at the molecular level, medicinal chemists can optimize their properties, leading to better therapeutic options for patients suffering from various health conditions.
