Definitions

  • the present invention belongs to the technical field of medicine, and relates to a phosphodiesterase 9 inhibitor represented by formula (I), or pharmaceutically acceptable salts, isomers, deuterated compounds, metabolites and prodrugs and applications thereof.
  • Phosphodiesterase is a class of proteases that can selectively degrade the important second messengers cGMP (cyclic guanosine phosphate) and cAMP (cyclic adenosine phosphate) in the body, thereby participating in important physiological processes in the body.
  • cGMP cyclic guanosine phosphate
  • cAMP cyclic adenosine phosphate
  • PDEs can be divided into 11 members (PDE1 ⁇ PDE11).
  • PDE9A is an important member of the PDE family, and it is widely expressed in the testis, brain, small intestine, skeletal muscle, heart, lung, thymus and pancreas.
  • PDE9A inhibitors are used to treat cognitive impairment diseases caused by central nervous system disorders, such as Alzheimer’s and schizophrenia, and brain
  • the two nucleotides cAMP and cGMP are important second messengers and play a central role in the process of cell signal transduction; they mainly activate protein kinases: protein kinase A (PKA) activated by cAMP, and activated by cGMP It is called protein kinase G (PKG).
  • PKA protein kinase A
  • PKG protein kinase G
  • the activated PKA and PKG can phosphorylate many cellular effectors, such as ion channels, G-protein coupled receptors, structural proteins, and conductance factors.
  • cAMP and cGMP may control most physiological processes in many organs in this way.
  • cAMP and cGMP can also directly act on effector proteins, thus playing the same role as mentioned above.
  • cGMP can directly act on ion receptors, thereby affecting the ion concentration in cells.
  • Phosphodiesterase (PDEs) hydrolyze cyclic monophosphate cAMP and cGMP, and convert them into inactivated monophosphate AMP and GMP.
  • Human PDE9 was first cloned and sequenced in 1998 and is the most selective PDE for cGMP reported so far.
  • the binding constant (Km) of PDE9 and cGMP is 170 nM, and the binding constant for cAMP is as high as 230,000 nM, and the selectivity is more than 1000 times.
  • Km binding constant
  • PDE9 inhibitors may increase the baseline cGMP concentration.
  • Pfizer s PF-04447943 (WO2008139293A1, Example 111) and BI’s BI-409306 (WO2009121919A1, Exp.51).

Description

PDE9抑制剂及其用途 技术领域
本发明属于医药技术领域,涉及式(I)所示的磷酸二酯酶9抑制剂,或其药学上可接受的盐、异构体、氘代化合物、代谢产物和前药及其应用。
背景技术
磷酸二酯酶(phosphodiesterase,PDEs)是一类蛋白酶,能选择性的降解体内重要的第二信使cGMP(环磷酸鸟苷)和cAMP(环磷酸腺苷),从而参与体内重要的生理过程。依据基因的序列同源性和对cGMP或cAMP的选择性,PDEs可分为(PDE1~PDE11)11个成员。其中,PDE9A是PDE家族中的重要一员,其广泛表达于睾丸、大脑、小肠、骨肌、心脏、肺、胸腺和胰脏。随着近几年的研究深入,已有多篇文献报道和临床数据证明,PDE9A抑制剂用于治疗由于中枢神经系统紊乱导致的认知损害方面的疾病,比如老年痴呆症和精神分裂症、大脑的神经变性过程疾病。cAMP和cGMP这两种核苷酸是重要的第二信使,在细胞信号传导过程中起着核心作用;它们主要活化蛋白激酶:由cAMP激活的称作蛋白激酶A(PKA),由cGMP激活的称作蛋白激酶G(PKG)。被激活的PKA和PKG可以磷酸化许多细胞效应蛋白,比如离子通道、G-蛋白耦联受体、结构蛋白、传导因子。因此,cAMP和cGMP通过这种方式可能控制许多器官中的大多数生理过程。同时,cAMP和cGMP也可以直接作用于效应蛋白,从而起到上述相同的作用。众所周知,cGMP可以直接作用于离子受体,从而影响细胞中的离子浓度。磷酸二酯酶(PDEs)水解环状单磷酸酯cAMP和cGMP,将其转化为失活的单磷酸酯AMP和GMP。
人类的PDE9最早在1998年被克隆和测序,是迄今为止报道的对cGMP选择性最高的PDE。PDE9与cGMP的结合常数(Km)为170nM,而对cAMP的结合常数值高达230000nM,选择性超过1000倍。和PDE2A及PDE5A比较,由于PDE9没有cGMP的结合区域,因此PDE9的催化活性并不会被cGMP增强,所以PDE9抑制剂可能提高基线cGMP浓度。
传统的PDE抑制剂不能抑制人类PDE9,因此,药物IBMX、dipyridamole、SKF94120、rolipram和vinpocetine对PDE9没有抑制活性或者很低。
目前市场上没有PDE9抑制剂药物,只有一些正在处于临床研发阶段的抑制剂,例如Pfizer公司的PF-04447943(WO2008139293A1,实施例111)和BI公司的BI-409306(WO2009121919A1,Exp.51),目前两个化合物正处于临床研究阶段。
另外,Merck也在专利WO2017019723A1、WO2017019726A1和WO2017019724A1中报道了一些具有PDE9抑制作用的化合物。如专利WO2017019723A1中的化合物I-8,其结构如下:
