Which drugs are tyrosine kinase inhibitors?
Examples of TKIs include:
- axitinib (Inlyta)
- dasatinib (Sprycel)
- erlotinib (Tarceva)
- imatinib (Glivec)
- nilotinib (Tasigna)
- pazopanib (Votrient)
- sunitinib (Sutent)
What does tyrosine kinase inhibitors do?
Tyrosine kinase inhibitors (TKIs) are a type of targeted therapy. TKIs come as pills, taken orally. A targeted therapy identifies and attacks specific types of cancer cells while causing less damage to normal cells.
How are receptor tyrosine kinases inhibited?
Inhibition of the angiogenic growth factor includes obstruction of the VEGF from its receptors by the development of monoclonal antibodies [[110, 111] and or development of small molecules that can inhibit the phosphorylation of tyrosine kinase domain [112].
Are tyrosine kinase inhibitors biologics?
Many targeted therapies are also biologic drugs. Targeted therapies include oral agents called tyrosine kinase inhibitors and monoclonal antibodies given IV in the office. Often, these types of drugs are safer and have fewer side effects than older chemotherapy drugs.
How many TKI drugs are there?
As of now, there are over 50 FDA-approved TKIs. Comprehensive lists of FDA-approved TKIs with additional information are available at NIH PubChem and FDA.gov.
What’s the difference between a biologic and a JAK inhibitor?
Because both suppress the immune system, they increase your risk of serious infections and certain cancers. JAK inhibitors may be safer because they aren’t linked to any allergies. Biologic drugs may cause an allergic reaction in a small amount of people.
Are JAK inhibitors considered immunosuppressants?
Tofacitinib inhibits JAK family members with a high degree of kinome selectivity (27, 28), and was developed by Pfizer as a JAK3 inhibitor to be used as immunosuppressant in organ transplantation and possibly for the treatment of autoimmune diseases.
Are TKI drugs chemotherapy?
Any drug used to treat cancer (including tyrosine kinase inhibitors or TKIs) can be considered chemo, but here chemo is used to mean treatment with conventional cytotoxic (cell-killing) drugs that mainly kill cells that are growing and dividing rapidly. Chemo was once one of the main treatments for CML.
What is a tyrosine kinase inhibitor?
Mary J. Cismowski, in xPharm: The Comprehensive Pharmacology Reference, 2007 The tyrosine kinase inhibitors are a family of small molecules or peptides with the ability to inhibit either cytosolic or receptor tyrosine kinases.
How do TKIs interact with tyrosine kinases?
TKIs interact with the ATP-binding site of tyrosine kinases (e.g., vascular endothelial growth factor receptor, VEGFR; platelet-derived growth factor receptor, PDGFR; stem cell factor receptor c-KIT; RET kinase), avoiding the transfer of a phosphate moiety from ATP to tyrosine in effector proteins.
What are EGFR tyrosine kinase inhibitors?
EGFR tyrosine kinase inhibitors, such as erlotinib (Tarceva®) and gefitinib (Iressa®), are ATP mimic agents that bind to ATP-binding site on the EGFR tyrosine kinase domain and block receptor phosphorylation.
What is the role of tyrosine kinase in the pathophysiology of EAE?
EphA4 receptor tyrosine kinase is a modulator of onset and disease severity of experimental autoimmune encephalomyelitis (EAE) PLoS One. 2013;8(2)e55948. [PMC free article][PubMed] [Google Scholar] 50.
