Selumetinib Chemical Properties,Usage,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. 2.1?months) 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.
  • brand name Koselugo
  • 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).
