Definitions

  • the invention relates to the field of medicine, in particular to an OCT4 highly selective activator, its pharmaceutical composition and preparation method, and its application in the regulation and regulation of Oct4 and its associated genes.
  • Regenerative medicine refers to the emerging science of using a variety of new technical disciplines to rebuild aging or functionally lost tissues and organs, and to treat related diseases through a variety of medical methods.
  • the important research direction of regenerative medicine is the mechanism of normal tissue characteristics and functions, the biological basis of post-traumatic repair, the regeneration mechanism of tissues and organs and the differentiation mechanism of various stem cells, so as to finally obtain effective biological treatment methods.
  • Embryonic stem cells ESCs, referred to as ES, EK or ESC cells
  • ES Embryonic stem cells
  • Shinya Yamanaka's team invented a "cocktail" method composed of four transcription factors, OCT4, SOX2, KLF4 and c-Myc, which can successfully reprogram terminally differentiated skin fibroblasts into differentiated pluripotent cells stem cells, which are called induced pluripotent cells (Takahashi K, et al., Cell, 2006, 126(4) pp.663-676; Takahashi K and Yamanaka S, Cell, 2007, 131(5) pp. 861-872). These stem cells have similar differentiation potential to embryonic stem cells, and can form the three most basic germ layers of human development: ectoderm, mesoderm and endoderm, and eventually form a variety of adult cells.
  • This invention breaks through the ethical restrictions on the use of human embryonic stem cells in medicine, and greatly expands the application potential of stem cell technology in clinical medicine.
  • Oct4 has been shown to be a major regulator of reprogramming and induction of cell plasticity (Malik, V et al., Nat. Commun. 2019, 10, 3477).
  • the Oct4 gene encodes a protein that plays a key role in embryonic development and stem cell pluripotency, and alternative splicing results in multiple transcript variants.
  • the protein encoded by Oct4 belongs to the POU domain family of transcription factors, located in Chromosome 17:35,825,200-35,829,401.
  • POU domain The hallmark feature of the POU transcription factor family is the POU domain, which consists of two structurally independent subdomains: a highly conserved 75-amino acid POU-specific (POU) region and a 60-amino acid carboxyl-terminal homology domain ( POUh).
  • POU POU-specific
  • POUh 60-amino acid carboxyl-terminal homology domain
  • Oct4 expression is regulated at the transcriptional level by cis-acting elements upstream of the Oct4 gene and chromatin structure methylation (Klemm JD, et al., Cell, 1994, 77:21-32; Brehm A, et al., Mol Cell Biol 1997;17:154-62).
  • POU domain transcription factors bind to specific octameric DNA and regulate cell type-specific differentiation pathways.
  • Oct4 containing the POU domain and Sox2 containing the HMG domain are the key transcription factors for maintaining the pluripotency of pluripotent cells (Nichols, J., et al., Cell, 1998, 95, 379 –391; Avilion, A., et al., 2003, Genes Dev.17, 126–140), at least part of their function in pluripotent cells is to drive the transcription of target genes through a cooperative interaction between the two (Tomioka , M., et al. Nucleic Acids Res. 2002; 30, 3202–3213).
  • the reprogramming method widely used mostly uses viruses or other types of vectors to overexpress Oct4 (Takahashi K, et al., Cell, 2006, 126(4): 663-676; Takahashi K and Yamanaka S, Cell, 2007 , 131(5):861-872); Yu J, et al. Science. 2007; 318:1917–1920).
  • This type of method has potential clinical risks in the clinical use of induced pluripotent stem cells (iPSC), such as the hidden danger of tumorigenicity brought about by the use of viral vectors; The complexity of clinical supervision, further, such products will bring high costs due to the use of carriers.
  • iPSC induced pluripotent stem cells

Description

OCT4高选择性活化剂 技术领域
本发明涉及医药领域,具体涉及OCT4高选择性活化剂,其药物组合物及制备方法,及其在调控Oct4及其关联基因的调控中的应用。
背景技术
再生医学是指利用多种新型技术学科来重建老化或功能损失的组织和器官,并通过多种医学手段来进行相关疾病治疗的新兴科学。再生医学的重要研究方向为正常组织特征与功能的机理,创伤后修复的生物学基础,以及组织器官的再生机制及多种干细胞分化机理,从而最终获得有效的生物治疗方法。其中,胚胎干细胞(Embryonic stem cell,ESCs,简称ES、EK或ESC细胞)是早期再生医学研究中最受人瞩目的细胞类型。但是这一细胞的获得和使用均具有较大的伦理争议,因为进行胚胎干细胞研究就必须破坏胚胎,而胚胎是人尚未成形时在子宫的生命形式。这一伦理争议大大阻碍了再生医学的推进和应用。
2006年,山中伸弥的团队发明了一种由OCT4,SOX2,KLF4和c-Myc四种转录因子构成的“鸡尾酒”法,能够成功将终端分化的皮肤成纤维细胞重编程成为具有分化多能性的干细胞,这种干细胞被称为诱导多能干细胞(induced pluripotent cells)(Takahashi K,et al.,Cell,2006,126(4)pp.663-676;Takahashi K and Yamanaka S,Cell,2007,131(5)pp.861-872)。这些干细胞具有和胚胎干细胞(embryonic stem cells)类似的分化潜能,能够形成人体发育最基本的三个胚层:外胚层,中胚层及内胚层,并最终形成多种成体细胞。这一发明突破了在医学上使用人胚胎干细胞的伦理限制,大大拓展了干细胞技术在临床医学上的应用潜力。
在诱导多能干细胞及胚胎干细胞的研究中,Oct4已被证明是重编程和诱导细胞可塑性的主要调节基因(Malik,V et al.,Nat.Commun.2019,10,3477)。Oct4基因编码的蛋白质在胚胎发育和干细胞多能性中起关键作用,选择性剪接导致多种转录物变体。Oct4编码的蛋白质属于转录因子的POU结构域家族,位于Chromosome 17:35,825,200-35,829,401。POU转录因子家族的标志性特征是POU域,它由两个结构独立的亚域组成:一个由高度保守75个氨基酸构成的POU特异(POU)区和一个60个氨基酸的羧基末端同源域(POUh)。Oct4的表达在转录水平受到Oct4基因上游的顺式作用元件和染色质结构甲基化的调控(Klemm JD,et al.,Cell,1994,77:21-32;Brehm A,et al.,Mol Cell Biol 1997;17:154-62)。Yeom等人通过分析来自Oct4基因组基因座的18Kb片段控制下LacZ报告基因的表达,确定了两个元素,他们将其命名为可能需要调节的近端增强子(PE)和远端增强子(DE),他们在这两个增强子中确定了转录因子的精确结合位点(Yeom Y,et al.Integrated Ann Indexes 1996;122:881-94)。POU域转录因子与特定的八聚体DNA结合并调节细胞类型特异性的分化途 径。其中,在iPSC形成过程中,含有POU结构域的Oct4和含有HMG结构域的Sox2是维持多能细胞多能性至关重要的转录因子(Nichols,J.,et al.,Cell,1998,95,379–391;Avilion,A.,et al.,2003,Genes Dev.17,126–140),它们在多能细胞中的至少部分功能是通过两者之间的协同相互作用来驱动靶基因的转录(Tomioka,M.,et al.Nucleic Acids Res.2002;30,3202–3213)。这些发现表明发育上的转换可以通过Oct4来控制。而目前广泛使用的重编程方法多通过病毒或者其它类型的载体来过表达Oct4(Takahashi K,et al.,Cell,2006,126(4):663-676;Takahashi K and Yamanaka S,Cell,2007,131(5):861-872);Yu J,et al.Science.2007;318:1917–1920)。此类方法在诱导多能干细胞(iPSC)的临床使用上存在潜在的临床风险,例如病毒载体的使用带来的致瘤性隐患;此外,载体的复杂GMP生产工艺也带来了诱导多能干细胞临床监管复杂性,进一步的,此类产品会因为载体的使用带来成本的高昂。
基于上述原因,本发明设计并使用苯并咪唑衍生物及氨基吡啶衍生物,通过Oct4启动子的化学调节,实现对其下游基因的表达调控。从而避免了使用病毒或者其它载体对Oct4的调控,进一步实现安全简便的化学小分子启动生物学表达功能。
