Definitions

  • the present invention belongs to the field of pharmaceutical chemistry and relates to a polycyclic compound as a thyroid hormone beta receptor agonist, a pharmaceutical composition containing the polycyclic compound, a preparation method thereof, and use thereof in preparing a drug for preventing, treating or alleviating diseases regulated by the thyroid hormone beta receptor.
  • Thyroid hormone is synthesized in the thyroid gland in response to thyroid stimulating hormone (TSH) secreted by the pituitary gland. Thyroid hormone plays a very important role in regulating body growth, development, metabolism, and matrix balance. Thyroid hormones exert their functions by binding to thyroid hormone receptors (THRs). THRs belong to the nuclear receptor superfamily. Nuclear receptors form heterodimers with their common ligands, retinoid X receptors, and function as ligand-induced transcription factors. Like other nuclear receptors, THRs have ligand-binding domains and DNA-binding domains, and regulate gene expression through ligand-dependent interactions with DNA-responsive elements (thyroid response elements, THREs).
  • THRs thyroid hormone receptors
  • THR ⁇ is mainly distributed in cardiac tissue and plays an important regulatory role in cardiac function.
  • THR ⁇ is mainly expressed in the liver and pituitary gland, regulating the metabolism of fatty acids and cholesterol, as well as regulating the secretion of thyroid-stimulating hormone.
  • Both THR ⁇ and THR ⁇ are expressed in brown adipose tissue (BAT), playing an important role in regulating basal oxygen consumption, fat storage, lipogenesis and lipolysis (Oppenheimer et al., J. Clin. Invest. 87(1): 125-32 (1991)).
  • BAT brown adipose tissue
  • THR agonists can increase metabolic rate, oxygen consumption and heat production, promote cholesterol metabolism into bile acid, and also reduce lipoprotein levels associated with atherosclerosis.
  • the liver and heart are the main target organs of THR agonists. In the liver, they mainly regulate genes related to the synthesis and metabolism of fatty acids and cholesterol, and affect carbohydrates by increasing glycogenolysis and gluconeogenesis and reducing the action of insulin. In the heart, they can reduce systemic vascular resistance, increase blood volume, and produce inotropic and chronotropic effects.
  • THR ⁇ agonists can also improve cellular lipid metabolism and play a role in lowering cholesterol and blood lipids. Therefore, it is of great significance to study and develop THR ⁇ agonists for the treatment and/or prevention of diseases regulated by thyroid hormone receptors.
  • the present invention has discovered a series of polycyclic compounds that serve as thyroid hormone beta receptor agonists and have potential value in preventing and/or treating diseases regulated by thyroid hormone beta receptors.

一种多环类甲状腺激素β受体激动剂及其用途
相关申请的交叉引用
本申请要求于2023年02月17日向中国国家知识产权局提交的第202310134989.4号和2023年11月16日提交的第202311537585.6号中国专利申请的优先权和权益,所述申请公开的内容通过引用整体并入本文中。
技术领域
本发明属于药物化学领域,涉及作为甲状腺激素β受体激动剂的多环类化合物、包含其的药物组合物、其制备方法、及其在制备用于预防、治疗或减轻由甲状腺激素β受体调节的疾病的药物中的用途。
背景技术
甲状腺激素(thyroid hormone,TH)是应答垂体分泌的促甲状腺激素(thyroid stimulating hormone,TSH)而在甲状腺中合成的。甲状腺素对调控身体生长、发育、代谢、以及基体平衡起着非常重要的作用。甲状腺激素通过与甲状腺激素受体(Thyroid hormone receptor,THR)结合发挥功能。THRs属于核受体超家族,核受体与其常见配体类视色素X受体一起形成异二聚体,作为配体诱导的转录因子发挥作用。与其它核受体一样,THRs具有配体结合域和DNA结合域,并通过与DNA效应元件(甲状腺效应元件,THREs)的配体依赖性相互作用来调节基因的表达。
目前THR有两种亚型:THRα和THRβ。THRα主要分布在心脏组织,对心脏的功能起重要调控作用。THRβ主要在肝脏和脑垂体表达,调控脂肪酸和胆固醇的代谢,以及调控促甲状腺激素分泌。THRα和THRβ均在棕色脂肪组织(BAT)中表达,在调节基础耗氧量、脂肪贮存、脂肪生成和脂解方面起重要作用(Oppenheimer等人,J.Clin.Invest.87(1):125-32(1991))。
THR激动剂可增加代谢率、耗氧量和产热,促进胆固醇代谢为胆汁酸,此外,还可降低与动脉粥样硬化有关的脂蛋白水平。肝脏和心脏是THR激动剂的主要靶器官。在肝脏中主要调节脂肪酸和胆固醇的合成及代谢相关的基因,并通过增加糖原分解和糖原异生以及降低胰岛素的作用来对碳水化合物类产生影响。在心脏中,可降低全身血管阻力、增加血容量和产生变力性和变时性作用。
THRβ激动剂还可以提高细胞脂代谢,发挥降胆固醇和血脂的功能。因此,研究并开发THRβ激动剂用于治疗和/或预防由甲状腺激素受体调节的疾病具有重要意义。
