ленватиниб мезилат

Lenvatinib mesylate (lenvatinib) is an oral targeted therapy medicine known as a receptor‐type tyrosine kinase inhibitor. It is a small-molecule drug (a drug that can enter cells easily), which was developed at Eisai in 2015. It was approved by the FDA in 2015 for the treatment of differentiated thyroid cancer that is either locally recurrent, metastatic, or progressive and did not respond to radioactive iodine treatment. In May 2016, the FDA approved the drug as a combination therapy with everolimus for the treatment of advanced renal cell carcinoma. Because VEGF (and fibroblast growth factor receptors, known as FGFRs) are thought to play a role in cardiovascular signaling pathways, VEGF2R and FGFR inhibition are thought to be the mechanisms behind the primary side effect of lenvatinib mesylate, which is hypertension.

Lenvatinib mesylate is used in cancer:(1) Endometrial carcinoma that is advanced and got worse after other systemic therapies. It is used with pembrolizumab in patients whose cancer is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) and cannot be treated with surgery or radiation therapy.(2) Hepatocellular carcinoma (a type of liver cancer). It is used as the first treatment in patients whose cancer cannot be removed by surgery.(3) Renal cell carcinoma (a type of kidney cancer) that is advanced(4)Thyroid cancer in certain patients whose cancer got worse, came back, or has spread to other parts of the body and did not respond to treatment with radioactive iodine.(5) Lenvatinib Mesylate is used in preparation of anti-human CTLA4xPD-1 bispecific antibodies for diagnosis, prevention and treatment of tumor or anemia.
Lenvatinib mesylate is also being studied in the treatment of other types of cancer.

ChEBI: Lenvatinib mesylate is a methanesulfonate salt obtained by reaction of lenvatinib with one molar equivalent of methanesulfonic acid. A multi-kinase inhibitor and orphan drug used (as its mesylate salt) for the treatment of various types of thyroid cancer that do not respond to radioiodine. It has a role as an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor, a fibroblast growth factor receptor antagonist, an orphan drug, a vascular endothelial growth factor receptor antagonist and an antineoplastic agent. It contains a lenvatinib(1+).

Lenvatinib mesylate works by blocking proteins that signal cancer cells to multiply. It also blocks proteins that signal the formation of new blood vessels that are needed to support tumor growth. Blocking these signals keeps cancer cells from growing.

lenvatinib Mesylate is a white powder sparingly soluble in acetic acid and slightly soluble in water. It is very slightly soluble in 1,3-dimethyl-2-imidazolidinone and practically insoluble in acetonitrile, dehydrated ethanol, 1-propanol, 2-propanol, 1-octanol, and isopropyl acetate. In aqueous solutions, lenvatinib mesylate is slightly soluble in 0.1 mol/L HCl and practically insoluble in Britton-Robinson buffer, pH 3-11.
