Definitions

  • the present invention has a long-chain fatty acid elongation enzyme 6 (Elongation of long chain fatty acid family member 6; hereinafter abbreviated as “Elovl6”) inhibitory action, and is a fragrance useful for the prevention and treatment of diabetes and the like. It relates to a ring compound.
  • Elovl6 long-chain fatty acid elongation enzyme 6
  • fatty acids are ingested by biosynthesis or diet by fatty acid synthase (FASN, fatty acid synthase) in the cytoplasmic fraction, and a part thereof undergoes chain length extension reaction to become long chain fatty acids.
  • FSN fatty acid synthase
  • the chain-lengthening reaction of long-chain fatty acids is a long-chain fatty acid that becomes a substrate with malonyl-CoA by the Elovl family of enzyme groups consisting of seven subtypes of Elovl (Elongation of long fatty acids) 1-7 It is considered that the first-stage condensation reaction with -CoA is catalyzed, and through a further three-stage enzymatic reaction, a long-chain fatty acid-CoA reaction product with two added carbon chains is obtained (Non-patent Document) 1).
  • Elovl6 was identified as an Elovl family molecule that is particularly highly expressed in the liver of SREBP-1a (sterol regulatory element binding protein-1a) transgenic mice (Non-patent Documents 2 and 3). Elovl6 is known to localize in the endoplasmic reticulum and catalyze the condensation reaction with malonyl-CoA using fatty acid-CoA with a carbon chain number of 12 to 16 (C12 to C16) as a substrate. It is known that it is induced, decreases physiologically by fasting, and increases by refeeding.
  • SREBP-1a sterol regulatory element binding protein-1a
  • Elovl6 genetically deficient in Elovl6 have been reported to be highly resistant to the induction of hyperinsulinemia, hyperglycemia and hyperleptinemia due to dietary or genetic load (non-patented Reference 4).
  • Elovl6 genetic deficiency or decreased gene expression increases C16 fatty acids, especially palmitoleate (C16: 1n7, palmitoleate), C18 fatty acids stearic acid (C18: 0, stearate), oleic acid (C18: 1n9, oleate) These fatty acid composition changes are thought to function to improve insulin resistance, glucose tolerance, and leptin resistance.
  • Non-patent Document 5 There is also a report confirming that palmitoleic acid is one of the humoral factors that act on anti-inflammatory and insulin sensitivity enhancement. Therefore, a compound having an Elovl6 inhibitory action is useful for the prevention and treatment of diabetes and the like.

Description

芳香環化合物Aromatic ring compounds
 本発明は、長鎖脂肪酸伸長酵素6(Elongation of long chain fatty acids family member 6;以下、「Elovl6」と略記することがある。)阻害作用を有し、糖尿病等の予防・治療に有用な芳香環化合物に関する。
[発明の背景]
The present invention has a long-chain fatty acid elongation enzyme 6 (Elongation of long chain fatty acid family member 6; hereinafter abbreviated as “Elovl6”) inhibitory action, and is a fragrance useful for the prevention and treatment of diabetes and the like. It relates to a ring compound.
[Background of the invention]
 ヒト生体内において、脂肪酸は、細胞質画分の脂肪酸合成酵素(FASN, fatty acid synthase)により生合成または食事により摂取され、その一部はさらに鎖長延長反応を受けて長鎖脂肪酸となる。長鎖脂肪酸の鎖長延長反応は小胞体に存在するElovl(Elongation of long chain fatty acids)1-7の7つのサブタイプから構成されるElovlファミリー酵素群によってマロニル-CoAと基質となる長鎖脂肪酸-CoAとの第一段階の縮合反応が触媒され、さらなる3段階の酵素反応を経て、炭素鎖が2個付加された長鎖脂肪酸-CoA反応生成物を与えると考えられている(非特許文献1)。 In the human body, fatty acids are ingested by biosynthesis or diet by fatty acid synthase (FASN, fatty acid synthase) in the cytoplasmic fraction, and a part thereof undergoes chain length extension reaction to become long chain fatty acids. The chain-lengthening reaction of long-chain fatty acids is a long-chain fatty acid that becomes a substrate with malonyl-CoA by the Elovl family of enzyme groups consisting of seven subtypes of Elovl (Elongation of long fatty acids) 1-7 It is considered that the first-stage condensation reaction with -CoA is catalyzed, and through a further three-stage enzymatic reaction, a long-chain fatty acid-CoA reaction product with two added carbon chains is obtained (Non-patent Document) 1).
 Elovl6はSREBP-1a(sterol regulatory element binding protein-1a)トランスジェニックマウス肝で特に高発現するElovlファミリー分子として同定された(非特許文献2、非特許文献3)。Elovl6は小胞体に局在し、炭素鎖数12~16(C12~C16)までの脂肪酸-CoAを基質としてマロニル-CoAとの縮合反応を触媒することが知られ、また肝臓における発現はSREBPによって誘導され、生理的には絶食によって減少し、再摂食によって亢進することが知られる。さらに、Elovl6を遺伝的に欠損したノックアウトマウスは食事性あるいは遺伝的負荷による高インスリン血症・高血糖・高レプチン血症の誘導に対して強い抵抗性を示すことが報告されている(非特許文献4)。Elovl6の遺伝的欠損あるいは遺伝子発現低下は、C16脂肪酸の特にパルミトレイン酸(C16:1n7, palmitoleate)を増加し、C18脂肪酸であるステアリン酸(C18:0, stearate)・オレイン酸(C18:1n9, oleate)を減少せしめ、これらの脂肪酸組成変化がインスリン抵抗性・耐糖能・レプチン抵抗性の改善に機能していると考えられている。パルミトレイン酸が抗炎症性・インスリン感受性亢進に働く液性因子の一つであることを裏付ける報告もある(非特許文献5)。
 従って、Elovl6阻害作用を有する化合物は、糖尿病等の予防および治療に有用である。
Elovl6 was identified as an Elovl family molecule that is particularly highly expressed in the liver of SREBP-1a (sterol regulatory element binding protein-1a) transgenic mice (Non-patent Documents 2 and 3). Elovl6 is known to localize in the endoplasmic reticulum and catalyze the condensation reaction with malonyl-CoA using fatty acid-CoA with a carbon chain number of 12 to 16 (C12 to C16) as a substrate. It is known that it is induced, decreases physiologically by fasting, and increases by refeeding. In addition, knockout mice genetically deficient in Elovl6 have been reported to be highly resistant to the induction of hyperinsulinemia, hyperglycemia and hyperleptinemia due to dietary or genetic load (non-patented Reference 4). Elovl6 genetic deficiency or decreased gene expression increases C16 fatty acids, especially palmitoleate (C16: 1n7, palmitoleate), C18 fatty acids stearic acid (C18: 0, stearate), oleic acid (C18: 1n9, oleate) These fatty acid composition changes are thought to function to improve insulin resistance, glucose tolerance, and leptin resistance. There is also a report confirming that palmitoleic acid is one of the humoral factors that act on anti-inflammatory and insulin sensitivity enhancement (Non-patent Document 5).
Therefore, a compound having an Elovl6 inhibitory action is useful for the prevention and treatment of diabetes and the like.
