Enzymes and Receptors

The term 'Enzymes and Receptors' represents a broad categorization of biological molecules rather than a specific therapeutic target. Enzymes are macromolecular biological catalysts that accelerate chemical reactions, while receptors are protein molecules that receive and transduce chemical signals (NIH, 2023; StatPearls, 2023). These two classes constitute the majority of known drug targets, mediating essential processes such as metabolism, gene expression, and cell communication. Because this entry refers to a general group of proteins, it lacks the specificity required for drug-target interaction analysis. In a clinical context, specific enzymes (e.g., Cyclooxygenase-2) or receptors (e.g., Mu-opioid receptor) are targeted to treat various diseases, including cancer, infections, and metabolic disorders (PubChem, 2024). Drugs interacting with enzymes usually function as inhibitors or activators, whereas those targeting receptors act as agonists or antagonists. Understanding the distinction between these classes is fundamental to pharmacology and drug design.

Enzymes are typically modulated through catalytic inhibition or activation, while receptors are targeted by agonists, antagonists, or allosteric modulators to initiate or block signaling cascades (StatPearls, 2023).
