Enzyme inhibitors are molecules that interact with enzymes to decrease their activity. By blocking the function of specific enzymes, these compounds can eliminate harmful pathogens or restore metabolic balance, which is why many pharmaceuticals are designed as enzyme inhibitors. In addition to their use in medicine, some enzyme inhibitors also serve as herbicides or pesticides. However, not every molecule that binds to an enzyme acts as an inhibitor—some can actually enhance enzyme activity, known as enzyme activators.
New enzyme inhibitors are typically discovered through two main pathways: one involves natural sources such as plants, animals, and microorganisms, while the other relies on synthetic chemical compounds. Among currently available drugs, 52% target receptors, 22% target enzymes, and 6% target ion channels, with the remaining 3% covering other mechanisms. This highlights the significant role enzyme inhibitors play in drug development.
The potential for discovering new medicines through enzyme inhibition remains vast and continues to be a key area of research. As scientists explore more complex biological systems, the development of enzyme-targeted therapies will likely remain a cornerstone of modern pharmacology for years to come.
