本発明は、 医薬、 特に虚血性疾患、 動脈硬化等の予防'治療薬として有用な 新規フェノール化合物、 その製造方法およびその合成中間体に関する。 背景技術  The present invention relates to a novel phenolic compound useful as a medicament, particularly a preventive / therapeutic agent for ischemic disease, arteriosclerosis, etc., a method for producing the same, and a synthetic intermediate thereof. Background art
虚血性疾患の発症における細胞膜傷害 (細胞死を含む) の発生機序は必ずし も解明されているわけではないが、 かかる細胞傷害過程においては、 活性酸素 の産生亢進が重要な役割を担っているものと考えられている。 また、 活性酸素 は脂質の過酸ィヒのみならず、 酵素や蛋白質の変性、 及び核酸の傷害等を引き起 こし、 これらが種々の臓器障害の原因となることも知られている。 例えば、 冠 動脈閉塞による心筋梗塞発作を発症した場合、 これが心原性ショックゃ致死性 不整脈等の重篤な症状を惹起しやすいため、 初期治療として、 梗塞部位の血流 再開を目的とした再灌流療法 (血栓溶解療法、 経皮的経管的冠動脈形成術 ( P T C A) , 冠動脈バイパス手術 (C A B G) 等) がしばしば施行される。 しかし ながら、 この場合、 血行再開によって心筋組織障害が悪化すること (虚血/再 灌流障害) も少なくない。 この虚血/再灌流障害の発症機序の一つとして、 活 个生酸素の関与が報告されており、 再灌流時に発生した酸素ラジカルが再灌流不 整脈を惹起し、 A T P産生障害に伴う細胞傷害や酵素蛋白活性増加に伴う細胞 月莫破壊によって心筋障害をきたすと考えられている。  Although the mechanism of cell membrane injury (including cell death) in the onset of ischemic disease is not necessarily elucidated, enhanced production of active oxygen plays an important role in such cell injury processes. Is believed to be It is also known that active oxygen causes not only peroxidation of lipids but also denaturation of enzymes and proteins, damage of nucleic acids, and the like, which cause various organ damage. For example, when a myocardial infarction attack due to coronary artery occlusion develops, it is likely to cause serious symptoms such as cardiogenic shock and lethal arrhythmia. Perfusion therapy (thrombolytic therapy, percutaneous transluminal coronary angioplasty (PTCA), coronary artery bypass surgery (CABG), etc.) is often performed. However, in this case, revascularization often exacerbates myocardial tissue damage (ischemia / reperfusion injury). It has been reported that active oxygen is involved as one of the onset mechanisms of this ischemia / reperfusion injury.Oxygen radicals generated during reperfusion cause reperfusion arrhythmia and are associated with impaired ATP production. It is thought that myocardial damage is caused by cell destruction due to cell injury and increased enzyme protein activity.

However, the known phenol derivative has characteristics suitable for an injection in terms of solubility and other aspects. It is hard to be good.

The reaction product was extracted with 4 ml of n-butanol, and the fluorescence of the extract was measured (excitation wavelength: 536 nm, emission wavelength: 552 nm). The inhibitory effect of the addition of the sample on the production of lipid peroxide was calculated as the inhibition rate of the control group (the group containing no sample-containing DMSO) with respect to the amount of lipid peroxide produced. The results were described as the concentration (IC 50 ; μΜ) of each sample required to suppress lipid peroxide production by 50 % from the concentration inhibition curve.
