MedKoo Cat#: 205531 | Name: Binimetinib (MEK-162)
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Binimetinib, also known as MEK162 (ARRY-162), is an oral, highly selective MEK inhibitor. In preclinical studies, MEK162 showed significant antitumor activities in cell lines and animal models. MEK162 is the first targeted therapy to show activity in patients with NRAS -mutated melanoma and might offer a new option for a cancer with few effective treatments.

Biological target:
Binimetinib (MEK162) is an oral and selective MEK1/2 inhibitor. Binimetinib (MEK162) inhibits MEK with an IC50 of 12 nM.
In vitro activity:
Cell lines with a KRAS (V12) mutation and KRAS gains or loss (n=7) are ∼10 times more resistant than those having neither a KRAS (V12) mutation nor KRAS CNV (n=14). Significant differences in baseline and MEK162-induced gene expression exist between the sensitive and resistant lines, especially in genes involved in RAS, EGF receptor and PI3K pathways. This was further supported by difference in signal transduction. MEK 162 blocked ERK1/2, as well as inhibited PI3K and S6 and increased p27KIP1 levels in the sensitive lines. Reference: Br J Cancer. 2014 Oct 28;111(9):1788-801. https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/25167228/
In vivo activity:
Treatment with Binimetinib (ARRY-438162) reduces disease severity in a dose-related manner in both animal models. ARRY-438162 in the CIA model inhibits increases in ankle diameter by 27% and 50% at 1 and 3 mg/kg. Microscopic examination of the ankle joints show Binimetinib (ARRY-438162) significantly inhibits lesions (inflammation, cartilage damage, pannus formation and bone resorption) by 32% and 60% at 1 and 3 mg/kg. In AIA, 3 and 10 mg/kg of Binimetinib (ARRY-438162) inhibit AIA ankle diameter 11% and 34. Reference: J Pheneger, et al. 2006, ACR Annual Scientific Meeting.
