イブルチニブ 化学特性,用途語,生産方法

• 用途

  イブルチニブ（Ibrutinib）は、B細胞性腫瘍（英語版）の治療に用いられる抗がん剤である。経口投与可能な選択的不可逆的酵素阻害薬であり、ブルトン型チロシンキナーゼ(Bruton's tyrosine kinase; BTK）を阻害する。 リンパ球の一つであるB細胞に由来する悪性腫瘍である瀰漫性大細胞型B細胞性リンパ腫や多発性骨髄腫の治療に使用される。

• 効能

  抗悪性腫瘍薬, ブルトン型チロシンキナーゼ阻害薬

• 商品名

  イムブルビカ (ヤンセンファーマ)

• 説明

  Ibrutinib (CAS: 936563-96-1) is a first-in-class,potent, orally administered covalently-binding inhibitor of BTK. In November 2013, the US FDA approved ibrutinib (also referred to as PCI-32765), for the treatment of patients with mantle cell lymphoma (MCL) who had received at least one prior therapy. Ibrutinib is a potent inhibitor of BTK that binds covalently to Cys-481 in the active site of BTK, resulting in inhibition of kinase activity. Ibrutinib does have significant activity against 19 other kinases, including seven with a cognate cysteine residue. These include BLK, BMX, ITK, TEC, EGFR, ERBB2, and JAK3.

• 使用

  Ibrutinib is a highly selective Bruton’s tyrosine kinase (Btk) irreversible inhibitor.

• 定義

  ChEBI: Ibrutinib is a member of the class of acrylamides that is (3R)-3-[4-amino-3-(4-phenoxyphenyl)pyrazolo[3,4-d]pyrimidin-1-yl]piperidine in which the piperidine nitrogen is replaced by an acryloyl group. A selective and covalent inhibitor of the enzyme Bruton's tyrosine kinase, it is used for treatment of B-cell malignancies. It has a role as an EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor and an antineoplastic agent. It is a pyrazolopyrimidine, an aromatic amine, an aromatic ether, a member of acrylamides, a N-acylpiperidine and a tertiary carboxamide.

• 適応症

  Ibrutinib is a non-receptor Bruton's tyrosine kinase inhibitor approved for the treatment of relapsed chronic lymphocytic leukemia(CLL), mantle cell lymphoma (MCL) and WaldenstrÖm's Macroglobulinemia (WM).

• 一般的な説明

  Class: non-receptor tyrosine kinase
  Treatment: CLL, MCL
  Oral bioavailability = 4% (fasted), 8% (fed)
  Elimination half-life = 3.2 h
  Protein binding = 97.3%

• 副作用

  The more common side effects of Ibrutinib are diarrhoea and bleeding. Therefore, you should drink plenty of water during treatment, in order to reduce the risk of dehydration using diarrhoea. Bleeding problems can be serious and may even lead to death. This may be manifested by blood or black stools (that look like tar); pink or brown urine; accidental bleeding, or severe or uncontrollable bleeding; spitting up blood or vomit that looks like coffee grounds; coughing up blood; bruising or small red or purple spots on the skin; dizziness; confusing changes in speech; or a headache that lasts for a long time or is severe. Prompt medical attention is needed if a serious condition develops.
  Other possible side effects are: increased risk of infection, fever, chills, weakness, confusion, or other signs or symptoms of infection; increased risk of heart disease, rapid and irregular heartbeat; dizziness; lightheadedness; shortness of breath; swelling of the feet, ankles, or legs; discomfort in the chest; or feeling lightheaded. High blood pressure, reduced blood counts, second primary cancer and tumour lysis syndrome (TLS). Different disease treatments exhibit different adverse effects, so the above side effects may not occur in full.
