| DrugBank Description: | Vemurafenib is a competitive kinase inhibitor with activity against BRAF kinase with mutations like V600E. It exerts its function by binding to the ATP-binding domain of the mutant BRAF. Vemurafenib was co-developed by Roche and Plexxikon and it obtained its FDA approval on August 17, 2011, under the company Hoffmann La Roche. After approval, Roche in collaboration with Genentech launched a broad development program. |
| CAS Number: | 918504-65-1 |
| Molecular Weight: | 489.922 |
| DrugBank Indication: | Vemurafenib is approved since 2011 for the treatment of metastatic melanoma with a mutation on BRAF in the valine located in the exon 15 at codon 600, this mutation is denominated as V600E. The V600E mutation, a substitution of glutamic acid for valine, accounts for 54% of the cases of cutaneous melanoma. Vemurafenib approval was extended in 2017, for its use as a treatment of adult patients with Erdheim-Chester Disease whose cancer cells present BRAF V600 mutation. Erdheim-Chester disease is an extremely rare histiocyte cell disorder that affects large bones, large vessels, central nervous system, as well as, skin and lungs. It is reported an association of Erdheim-Chester disease and V600E mutation. |
| DrugBank Pharmacology: | BRAF activation results in cell growth, proliferation, and metastasis. BRAF is an intermediary molecule in MAPK whose activation depends on ERK activation, elevation of cyclin D1 and cellular proliferation. The mutation V600E produces a constitutively form of BRAF. Vemurafenib has been shown to reduce all activation markers related to BRAF; in clinical trials, vemurafenib treatment showed a reduction of cytoplasmic phosphorylated ERK and a cell proliferation driven by Ki-67. Studies also reported decrease in MAPK-related metabolic activity. All the different reports indicate thet Vemurafenib generates an almost complete inhibition of the MAPK pathway. |
| DrugBank MoA: | Vemurafenib is an orally available inhibitor of mutated BRAF-serine-threonine kinase. Vemurafenif is a small molecule that interacts as a competitive inhibitor of the mutated species of BRAF. It is especially potent against the BRAF V600E mutation. Vemurafenib blocks downstream processes to inhibit tumour growth and eventually trigger apoptosis. Vemurafenib does not have antitumour effects against melanoma cell lines with the wild-type BRAF mutation. |
