Selumetinib Chemical Properties,Uses,Production
Indications and Usage
Selumetinib, 1 has a chemical name of 5-[(4-Bromo-2-chlorophenyl)amino]-4-fluoro-N-(2-hydroxyethoxy)-1-methyl-1H-benzimidazole-6-carboxamide. It was developed by British company AstraZeneca and is used to treat advanced non-small cell lung cancer (NSCLC). It is mainly used to treat bile duct cancer, colon cancer, NSCLC, etc. Currently, Selumetinib is in stage III clinical trials for treatment of NSCLC.
Mechanisms of Action
Selumetinib is the first mitogenextracellular kinase (MEK1/2) inhibitor to be used in thyroid cancer clinical trials. It inhibits extracellular signal regulating kinase (ERK/2) and activates caspase to dramatically inhibit ERK1/2 phosphorylation.
Clinical Research
In phase II clinical trials of radioiodine-refractory papillary thyroid carcinoma, 39 patients took daily oral doses of Selumetinib (100mg bid) for 28 days; results showed that 21 patients’ conditions stabilized (54%), 11 patients’ conditions worsened (28%), 49% patients’ conditions were stable for 16 weeks, 36% patients’ conditions were stable for 24 weeks, and survival terms did not progress to 32 weeks. Negative reactions mainly consisted of rashes (59%), diarrhea (44%), and weakness (41%). Some studies found that after treating 20 patients with thyroid cancer with Selumetinib (75mg bid) for 4 weeks, Selumetinib increased the iodine uptake and retention of patients with radioiodine-refractory papillary thyroid carcinoma. In a blind and random comparative study between a Selumetinib and Docetaxel (DOC) combination treatment group and DOC and placebo treatment group for 87 mutant NSCLSC patients, survival times were 9.4 months and 5.2 months, PFS were 5.3 months and 2.1 months, RR were 37% and 0%, thus showing dramatic differences. Selumetinib’s main negative reactions include neutrophil depletion, dermatitis, and respiratory failure.
Binding Mode
In the co-crystal structure of selumetinib in
complex with MEK1 and AMP–PNP (Fig. 3),
selumetinib binds to a unique and specific allosteric
pocket on the N-terminal domain of MEK1, next to a
typical ATP-binding site. This binding results in a
conformational change, which prevents the RAF-induced phosphorylation, and locks MEK1/2 into a
catalytically inactive state, thereby blocking the RAS
signaling. The imine nitrogen of the
benzo[d]imidazole core hydrogen bonds to the
amide NH of Ser212, and the three oxygen atoms of
the amide side chain form three hydrogen bonds with
the primary amine of Lys97. In addition, the terminal hydroxyl group hydrogen bonds to the α-phosphoryl
oxygen of AMP–PNP (Fig. 4).
Description
Selumetinib (AZD6244; ARRY-142886) is an oral MEK inhibitor. In a randomized trial, NSCLC patients with wild-type KRAS were randomized to erlotinib alone or combination therapy with selumetinib, while mutant KRAS patients were randomized to selumetinib alone or combination therapy. The primary end points were PFS for the KRAS wild-type cohort and objective response rate (ORR) for the KRAS mutant cohort. Results were not impressive, with no PFS difference in the KRAS wild-type arm (2.4 vs. 2.1months) and no ORR difference in the KRASmutated subgroup (0% vs. 10%). A planned trial of selumetinib in combination with the anti-PD-L1 antibody durvalumab has since been suspended (NCT03004105).
Uses
It is a tight-binding, uncompetitive inhibitor of mitogen-activated protein kinase kinases (MEK) 1 and 2 currently in clinical development. It is useful as biomarker in human lung cancer cell. Potent MEK inhibitor.
Definition
ChEBI: A member of the class of benzimidazoles that is 1-methyl-1H-benzimidazole which is substituted at positions 4, 5, and 6 by fluorine, (4-bromo-2-chlorophenyl)amino, and N-(2-hydroxyethoxy)aminocarbonyl groups, respectiv ly. It is a MEK1 and MEK2 inhibitor.

General Description
Class: dual threonine/tyrosine kinase; Treatment: children with NF1; Other name: AZD-6244, ARRY-142886; Oral bioavailability = 62%; Elimination half-life = 6.2 h; Protein binding = 97.7%
target
MEK1
Metabolism
Following oral administration of radiolabeled
selumetinib, the most prominent drug-related
component in the plasma was selumetinib,
accounting for 40% of the plasma radioactivity. The
major circulating metabolite was an amide
glucuronide 2, which accounted for 22% of the
plasma radioactivity. This metabolite resulted from loss of the ethanediol moiety to give the primary
amide 1, which underwent glucuronidation and an
additional loss of 2 mass units, most likely due to
further oxidation of the N-methylbenzimidazole
moiety (Fig. 5).
storage
Store at -20°C
Dosage
Selumetinib is characterized by a moderate oral bioavailability (62%) and a relatively short half-life (6.2 h), and these properties contribute to twice-daily dosing regimen (25 mg dosage).
Background
Selumetinib, also known as ARRY-142886, is a highly potent and selective non-ATP competitive inhibitor of MEK with an IC50 of 14 nM. Researchers have shown this small molecule to inhibit growth in cell lines containing B-Raf and Ras mutations with no effect on normal fibroblasts. Treatment with Selumetinib induces apoptosis and differentiation in tumors from cells with B-Raf or K-Ras mutations.
