Isosterism is a concept in medicinal chemistry where two or more chemical compounds have a similar shape and size as well as similar physical and chemical properties. These compounds can exhibit similar biological activity due to their resemblance to each other.

Isosteres are groups of atoms or molecules that have similar physical or chemical properties. These isosteres can be substituted for each other in a chemical structure without significantly altering the biological activity of the compound.

Importance in Drug Design

Isosterism plays a crucial role in drug design as it allows medicinal chemists to make strategic modifications to a compound to enhance its pharmacological properties. By replacing a functional group with an isosteric group, the compound's activity, potency, or pharmacokinetic profile can be improved.

Types of Isosteres

There are different types of isosteres that can be used in drug design, such as bioisosteres, classical isosteres, and non-classical isosteres. Each type has its own set of rules and principles that govern their application in chemical modifications.

Applications in Drug Development

Isosterism has been extensively used in the development of various drugs, ranging from antibiotics to anticancer agents. By incorporating isosteric replacements in drug molecules, scientists can optimize the therapeutic efficacy and safety profiles of medications.

Overall, isosterism is a valuable tool in medicinal chemistry that allows researchers to fine-tune the properties of drug compounds for improved clinical outcomes. Understanding the principles of isosterism can lead to the development of more potent and selective drugs with fewer side effects.
