Inhibition
Inhibition — The decrease or prevention of a biological activity by a compound, measured by IC50 values in enzyme and receptor binding studies.
What Is Inhibition?
Inhibition is the reduction or blockade of a biological process by a molecule. Peptide inhibitors bind to enzyme active sites (substrate-based inhibitors), receptor binding sites (antagonists), or protein-protein interaction interfaces (PPI inhibitors) to prevent the target's normal function.
Inhibition Types
- Competitive: Peptide competes with substrate for active site. Overcome by excess substrate
- Non-competitive: Binds allosteric site. Cannot be overcome by excess substrate
- Irreversible: Covalent modification of target. Permanent inactivation. Suicide inhibitors
- Measurement: IC50, Ki values quantify inhibitor potency
Frequently Asked Questions
What is Inhibition?

Why is Inhibition important in peptide research?
Inhibition is a fundamental concept in pharmacology as it relates to peptide science. It directly influences experimental design, compound characterization, and the reliability of research outcomes across biochemistry and molecular biology disciplines.
