Inhibitors are an important subclass of therapeutic proteins that play a central role in regulating enzymatic activity and controlling biological pathways in the human body. By modulating the activity of specific enzymes or receptors, these therapeutic proteins can either promote or inhibit certain biochemical reactions that are critical for maintaining homeostasis. Inhibitors are particularly valuable in the treatment of a number of diseases caused by the overactivity of certain enzymes, uncontrolled cell growth or immune system dysfunction.

Therapeutic inhibitors can be derived from natural sources or created using recombinant DNA technology. They are primarily used to treat conditions such as chronic inflammation, genetic disorders, cardiovascular disease, cancer and autoimmune diseases. These inhibitors work by binding directly to target enzymes, receptors or substrates and preventing them from carrying out their harmful functions. Some inhibitors are designed to mimic natural inhibitors found in the body, while others are modified to improve their potency, specificity and pharmacokinetic properties.

Creative BioMart provides an extensive selection of inhibitor-based therapies to advance medical research and treatment.

What Are Inhibitors?

In the context of therapeutic proteins, inhibitors are bioactive molecules that interfere with or block the action of specific proteins, enzymes or receptors involved in disease processes. These inhibitors can either bind directly to their target molecule, preventing its activity, or modulate the function of the molecule by changing its structure. Inhibitors can be divided into two main types: enzyme inhibitors and receptor antagonists.

• Enzyme Inhibitors: These inhibitors prevent the action of enzymes that catalyze biochemical reactions, many of which are critical to disease progression. Enzyme inhibitors can block enzyme activity by binding to the active site (competitive inhibition) or by binding elsewhere on the enzyme to change its shape (non-competitive inhibition).
• Receptor Antagonists: These inhibitors target receptors, often proteins found on the surface of cells, to prevent their activation by ligands (e.g. hormones, neurotransmitters). By inhibiting receptor activation, these therapeutic proteins can reduce the signaling pathways that drive disease processes such as inflammation or cancer cell growth.

The Role of Inhibitors in Disease Treatment

Enzymes play essential roles in virtually every biochemical pathway, from digestion to DNA replication, but when these enzymes are overactive, they can contribute to a wide range of diseases. Inhibitors, as therapeutic proteins, are used to block or reduce the activity of these enzymes or other key molecules, providing a method to manage and treat various diseases. Some of the major therapeutic uses of inhibitors include:

• Inflammation and Immune Response: Inhibitors can be used to modulate the immune system and prevent excessive inflammation characteristic of diseases such as rheumatoid arthritis, lupus and other autoimmune disorders.
• Genetic Disorders: Certain genetic diseases result from the over- or under-activity of certain enzymes or proteins. Inhibitors can target these molecular imbalances and correct dysfunctional pathways.
• Cancer: Many cancers are driven by enzymes or proteins that promote uncontrolled cell growth. Inhibitors that target these molecules are used as part of cancer therapy to stop tumor progression and metastasis.
• Infection: Inhibitors can also be used to block enzymes produced by pathogens, such as bacteria or viruses, to stop their growth and spread.

Hot Products

• Aprotinin: Aprotinin is a broad-spectrum serine protease inhibitor that blocks the activity of enzymes involved in blood clotting and fibrinolysis. It is used to prevent excessive bleeding during heart surgery or liver transplantation. Aprotinin reduces the activation of plasminogen and other proteases, helping to maintain clot stability and minimize bleeding during surgery.
• Conestat Alfa (C1 Esterase Inhibitor): Conestat alfa is a recombinant form of human C1 esterase inhibitor used to treat hereditary angioedema (HAE), a genetic condition in which the body's inability to regulate C1 esterase activity leads to episodes of swelling and inflammation. By providing a recombinant version of this key inhibitor, conestat alfa helps control HAE symptoms by reducing the frequency and severity of swelling attacks.
• Ulinastatin: Ulinastatin is a urinary trypsin inhibitor (UTI) that has been shown to have beneficial effects in the treatment of acute pancreatitis and to reduce inflammation and protect organs from damage during severe infections. It works by inhibiting the activity of several enzymes, including trypsin, elastase, and others that contribute to tissue damage during inflammatory responses.
• Desirudin: Desirudin is a recombinant hirudin analog used as an anticoagulant to prevent venous thromboembolism in patients undergoing total hip replacement surgery. It works by directly inhibiting thrombin, a key enzyme in the blood coagulation cascade, thereby preventing clot formation and reducing the risk of deep vein thrombosis (DVT) and pulmonary embolism.
• Ecallantide: Ecallantide is a potent inhibitor of plasma kallikrein, an enzyme involved in the production of bradykinin, which is responsible for the swelling seen in hereditary angioedema (HAE). By inhibiting kallikrein, ecallantide helps prevent HAE attacks and is used as an on-demand therapy for acute attacks of this rare genetic disorder.
• Blisibimod: Blisibimod is a recombinant fusion protein designed to inhibit B cell activating factor (BAFF), which is involved in the activation and survival of B cells. By inhibiting BAFF, blisibimod reduces B-cell activity, which is beneficial in autoimmune diseases such as lupus, where excessive B-cell activity plays a central role in the disease.
