Definitions
- the present invention relates to the field of pharmaceutical chemistry, and in particular to a class of sulfonamide compounds containing heterocyclic rings and applications thereof in preparing drugs for treating related diseases.
- Mitotic enzymes are widely used clinically as targets for tumor therapy, and many anti-mitotic drugs are clinically used, such as microtubule-targeting agents, which can stabilize microtubules or prevent microtubule assembly.
- microtubules are an important component of the mitotic spindle, and the disruption of microtubule dynamics by these drugs leads to mitotic arrest and inhibition of cancer cell growth.
- microtubule-targeting agents are widely used as standard therapies for the treatment of a variety of cancers, these drugs have significant toxicity, including bone marrow suppression and neurotoxicity, due to damage to normal cells. Therefore, it is of great significance to develop new mitotic enzymes as therapeutic targets to prevent cancer cell proliferation and improve safety.
- Kinesin is a type of mitotic enzyme that plays an important role in the dynamics of spindle assembly, chromosome separation, centriole separation, etc.
- Mitotic kinesin is a motor protein that uses ATP hydrolysis to move along microtubule filaments and coordinate proper bipolar spindle formation, chromosome alignment and separation.
- inhibitors of mitotic kinesin Eg5 and CENP-E have no significant clinical therapeutic effects and have target mechanism toxicity.
- KIF18A kinesin-like protein 18A
- KIF18A is a kinesin expressed in the G2/M phase of the cell cycle and is a member of the kinesin-8 family of kinesins. In metaphase of cell division, it mainly regulates chromosome positioning and spindle length. KIF18A is believed to control chromosome positioning and spindle tension by affecting the dynamics of the plus end of the centromere microtubules. KIF18A deficiency leads to spindle elongation, chromosome misalignment, and activation of mitotic checkpoints, and its overexpression leads to the formation of multipolar spindles.
- KIF18A is overexpressed in a variety of tumors, such as breast cancer, ovarian cancer, and colon cancer; it is associated with tumor grade and degree of metastasis. Abnormal cell cycle regulation and chromosomal instability are common characteristics of solid tumors, and chromosomally unstable cells are more sensitive to anti-mitotic treatment. In chromosomally unstable cancer cells, KIF18A knockdown is associated with impaired cell division (including activation of spindle assembly checkpoints, formation of multipolar spindles, and induction of cell apoptosis), but does not affect the division of normal cells and cancer cells with normal karyotypes.
- KIF18A small molecule inhibitors of KIF18A can effectively and selectively target cancer cells with CIN features while largely sparing normal Therefore, the development of KIF18A small molecule inhibitors is of great research significance for cancer treatment.

Description
本发明主张如下优先权
申请号:CN202211407231.5,申请日:2022年11月10日;
申请号:CN202310469318.3,申请日:2023年4月26日。
本发明涉及药物化学领域,具体涉及一类含并杂环的磺酰胺类化合物及其在制备治疗相关疾病的药物中的应用。
细胞周期调控改变及染色体不稳定是许多人类恶性肿瘤的常见特征。有丝分裂酶作为肿瘤治疗靶标,临床应用广泛,很多抗有丝分裂药物得到临床应用,如微管靶向剂,可以稳定微管或阻止微管组装。微管是有丝分裂纺锤体的重要组成部分,这些药物对微管动力学的破坏导致有丝分裂停滞和癌细胞生长的抑制。尽管微管靶向剂被广泛用作治疗多种癌症的标准疗法,但由于对正常细胞的损害,这些药物具有显着的毒性,包括骨髓抑制和神经毒性。因此,开发新型的有丝分裂酶作为治疗靶标,阻止癌细胞增殖,提高安全性,具有重要意义。
驱动蛋白是有丝分裂酶的一种,在纺锤体的组装、染色体的分离、中心粒分离等动力学过程中发挥重要角色。有丝分裂驱动蛋白是利用ATP水解,沿微管细丝定向移动并协调适当的双极纺锤体形成、染色体排列和分离的运动蛋白。其中有丝分裂驱动蛋白Eg5和CENP-E的抑制剂在临床治疗效果不显著,且具有靶点机制毒性。
KIF18A(kinesin-like protein 18A)是一种在细胞周期的G2/M期表达的驱动蛋白,是驱动蛋白kinesin-8家族中的一员。在细胞分裂中期,主要调控染色体定位及纺锤体长度。KIF18A被认为通过影响着丝点微管正端的动力学来控制染色体定位和纺锤体的张力。KIF18A缺失会导致纺锤体变长、染色体错位和有丝分裂检查点的激活,它的过表达导致多极纺锤体的形成。KIF18A在多种肿瘤中过表达,如乳腺癌、卵巢癌、结肠癌等;与肿瘤级别及转移程度相关。细胞周期调控异常及染色体不稳定是实体瘤的常见特征,染色体不稳定细胞对抗有丝分裂治疗更加敏感。在染色体不稳定癌细胞中,KIF18A敲低与细胞分裂受损具有相关性(包括纺锤体组装检查点激活、多极纺锤体形成,诱导细胞凋亡),但不影响正常细胞及正常染色体组型癌细胞的分裂。临床前研究显示,染色体不稳定细胞中微管动力学的改变使其特别依赖KIF18A来减少着丝粒-微管的周转及限制微管的生长。在缺乏KIF18A活性的情况下,染色体不稳定细胞中着丝粒-微管附着和中心体完整性的维持受到损害,随后导致有丝分裂阻滞和中心体碎裂的延长,从而抑制细胞增殖。
KIF18A的小分子抑制剂能够有效地选择性靶向具有CIN特征的癌细胞,同时在很大程度上不影响正
常体细胞的分裂。因此,开发KIF18A小分子抑制剂对于癌症治疗,具有重要的研究意义。

定义与说明
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。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。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。
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。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。
除非另有说明,“(+)”表示右旋,“(-)”表示左旋,“(±)”表示外消旋。
除非另有说明,用楔形实线键和楔形虚线键表示一个立体中心的绝对构型,用直形实线键和直形虚线键表示立体中心的相对构型,用波浪线表示楔形实线键
或楔形虚线键或用波浪线表示直形实线键或直形虚线键
除非另有说明,术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。若互变异构体是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(proton tautomer)(也称质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体过量(ee值)为80%。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚(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,取代基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。
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。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
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。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或波浪线表示。例如-OCH3中的直形实线键表示通过该基团中的氧原子与其他基团相连;中的直形虚线键表示通过该基团中的氮原子的两端与其他基团相连;中的波浪线表示通过该苯基基团中的1和2位碳原子与其他基团相连;
表示该哌啶基上的任意可连接位点可以通过1个化学键与其他基团相连,至少包括
这4种连接方式,即使-N-上画出了H原子,但是仍包括这种连接方式的基团,只是在连接1个化学键时,该位点的H会对应减少1个变成相应的一价哌啶基。
除非另有规定,术语“C1-3烷基”用于表示直链或支链的由1至3个碳原子组成的饱和碳氢基团。所述C1-
3烷基包括C1-2和C2-3烷基等;其可以是一价(如甲基)、二价(如亚甲基)或者多价(如次甲基)。C1-3烷基的实例包括但不限于甲基(Me)、乙基(Et)、丙基(包括n-丙基和异丙基)等。
