Definitions
- the present invention relates to a type of protein degradation targeted chimera (PROTAC) and its application in preparing medicines for treating related diseases. Specifically, it relates to a compound represented by formula (I) or a pharmaceutically acceptable salt thereof.
- PROTAC protein degradation targeted chimera
- Proteolysis Targeting Chimera is a technology that uses the ubiquitin-proteasome system to target specific proteins and induce their degradation in cells.
- the ubiquitin-proteasome system is the main pathway of intracellular protein degradation. Its normal physiological function is mainly responsible for the removal of intracellular degeneration, mutation or harmful proteins. The degradation of more than 80% of the intracellular protein depends on the ubiquitin-proteasome system.
- PROTAC uses the cell's own protein destruction mechanism to remove specific target proteins in the cell.
- the PROTAC molecule is a heterogeneous bifunctional small molecule consisting of a ligand that binds to the target protein, a ligand that binds to the E3 ubiquitin ligase, and a linker that connects the two ligands. It can be used at the same time. Binding target protein and E3 ubiquitin ligase to form a ternary complex. The mechanism of action is to make the target protein and E3 ligase close enough by binding to the target protein, so that E3 ligase can ubiquitinate and label the target protein, and then The process by which the proteasome degrades tagged proteins.
- PROTAC molecules Compared with traditional small molecule drugs, PROTAC molecules have many potential advantages: 1) The most important thing is to change the target from "non-druggable” to "druggable". Most small molecule drugs or macromolecular antibodies require Long-term and high-strength binding to the active site of the target protease can take effect. However, more than 80% of the protein surface lacks obvious drug-making sites. It is difficult to target these proteins with current drug strategies. The PROTAC molecule is different. Above, as long as there are certain cracks or gaps on the protein surface, PROTAC molecules can capture and remove these proteins; 2) Remove protein accumulation, the binding of drugs and target proteins can cause the accumulation of target proteins, and PROTAC molecules can directly degrade the proteins.
- PROTAC technology has been used to target a variety of proteins, including transcription factors, backbone proteins, enzymes and regulatory proteins. Therefore, PROTAC technology has very broad application prospects in the medical field, such as tumor, cardiovascular, degenerative and viral infections and other diseases.
- the present invention provides a compound represented by formula (I) or a pharmaceutically acceptable salt thereof,
- PTM is selected from drugs or derivatives thereof that bind to a targeted protein
- L is the chain connecting PTM and ULM
- ULM is selected from the structures shown in formulas (III-1) and (III-2),
- R 1 and R 2 are each independently selected from H and C 1-3 alkyl

本发明涉及一类蛋白降解靶向嵌合体(PROTAC),及其在制备治疗相关疾病的药物中的应用。具体涉及式(I)所示化合物或其药学上可接受的盐。
蛋白降解靶向嵌合体(Proteolysis Targeting Chimera,PROTAC)是一种应用泛素–蛋白酶体系统靶向特定蛋白质并诱导其在细胞内降解的技术。泛素-蛋白酶体系统是细胞内蛋白质降解的主要途径,其正常生理功能主要负责清除细胞内变性、突变或有害蛋白质,细胞内80%以上蛋白质的降解都依赖于泛素–蛋白酶体系统。PROTAC利用细胞自身的蛋白质破坏机制,清除细胞中的特异性靶向蛋白。
PROTAC分子是一种异质双功能小分子,由一个与目标蛋白结合的配体、一个与E3泛素连接酶结合的配体以及一个连接这两个配体的连接体三部分组成,可同时结合目标蛋白和E3泛素连接酶形成三元复合物,其作用机制是通过与目标蛋白结合使目标蛋白和E3连接酶能足够靠近,从而E3连接酶可以泛素化并标记目标蛋白,再经蛋白酶体降解标记蛋白的过程。
与传统小分子药物相比,PROTAC分子具有诸多潜在的优势:1)最为重要的是,使靶点从“不可成药性”变成“可成药性”,大多数小分子药物或大分子抗体需要与靶蛋白酶的活性位点长时间和高强度的结合才能发挥作用,但是80%以上的蛋白表面缺乏明显的成药位点,以目前的药物策略很难靶向这些蛋白,而PROTAC分子不同,理论上,只要蛋白表面有一定的裂缝或缺口,PROTAC分子就能捕获并清除这些蛋白;2)清除蛋白淤积,药物与靶蛋白的结合可以引起靶蛋白的积聚,而PROTAC分子可将蛋白直接降解,从而减少蛋白在体内的蓄积;3)克服耐药性,靶蛋白特定位点的突变通常会阻断小分子药物与蛋白的结合,产生耐药性,而PROTAC分子通过泛素–蛋白酶体途径将靶蛋白降解,克服了耐药性;4)降低毒性,PROTAC分子只需要催化剂量即可发挥药效,减少了药物在体内的大量蓄积,极大地降低了脱靶毒性的产生;5)“事件驱动”而非“占位驱动”,无论小分子抑制剂,还是大分子抗体,都需持续占据靶蛋白的活性位点以阻断功能,而PROTAC分子是“事件驱动”,只需要与靶蛋白结合后打上泛素标签就能降解蛋白,PROTAC分子可继续游离出来,从而长时间持续发挥药效。
迄今为止,PROTAC技术已可用于靶向多种蛋白质,包括转录因子、骨架蛋白、酶和调节蛋白等。因此,PROTAC技术在医药领域具有非常广阔的应用前景,诸如肿瘤、心血管、退行性和病毒感染等疾病领域的治疗潜力。

相关定义
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
术语“靶向蛋白”表示结合本发明化合物并被降解的蛋白质或多肽。
术语“药物或其衍生物”包括已开发可结合于靶向蛋白的的药物或其衍生物和将来开发的可结合于靶向蛋白的药物或其衍生物。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。

3H),碘-125(
125I)或C-14(
14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。
术语“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
术语“被置换”指特定的原子或基团可以被替换为指定的其他原子或基团。如CH
3CH
2CH
3中的CH
2可被O、S、NH置换得到CH

3、CH
3SCH
3和CH
3NHCH
3。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR)
0-,表示该连接基团为单键。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,
中连接基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成
也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定,当某一基团具有一个或多个可连接位点时,该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的,且可连接位点存在H原子时,则连接化学键时,该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。当基团为并环结构,该并环结构通过不定位化学键与其他基团相连时,该并环的任意一个或多个位点可以通过化学键与其他基团相连。所述位点与其他基团连接的化学键可以用直形实线键
直形虚线键
