Definitions

  • the invention belongs to the field of medicinal chemistry, and in particular relates to an antitumor compound and a pharmaceutical composition thereof.
  • Ubiquitin-proteasome pathway-mediated protein degradation is an important mechanism by which the body regulates intracellular protein levels and functions. Once the proteasome exceeds normal levels, it causes a decrease in growth inhibition, a decrease in apoptosis, and promotes angiogenesis, thereby causing various tumor diseases, and thus the proteasome is an important target for drugs such as cancer. Proteasome inhibitors inhibit tumor cell growth and promote apoptosis by blocking cellular proteasome degradation.

Description

一种新的硼酸衍生物及其药物组合物 技术领域
本发明属于药物化学领域,具体涉及一种抗肿瘤化合物及其药物组合物。
背景技术
泛素蛋白酶体途径介导的蛋白降解是机体调节细胞内蛋白水平与功能的一个重要机制。一旦蛋白酶体超出正常水平,其会导致生长抑制的减弱、细胞凋亡的减少、以及促进血管生成,从而引发多种肿瘤疾病,因此蛋白酶体是抗癌等药物的重要靶点。蛋白酶体抑制剂通过阻断细胞蛋白酶体降解,从而抑制肿瘤细胞生长以及促进细胞凋亡。
多发性骨髓瘤(multiple myeloma,MM)是一种浆细胞癌,见于骨髓。多发性骨髓瘤中,一组浆细胞或骨髓瘤细胞转化为癌细胞并增生,使浆细胞的数目高于正常水平。由于浆细胞在体内广泛游走,有可能累及体内多数骨骼,可能导致压缩性骨折、骨溶解性病灶和相关疼痛。多发性骨髓瘤可导致若干严重健康问题,累及骨骼、免疫系统、肾脏和个体的红细胞计数,部分较常见症状包括骨骼疼痛和疲乏。
结肠癌也是高发的肿瘤类型,尽管已经有大量的治疗药物和手段,但该领域高价值的治疗药物仍然是未满足的临床需求。
Bortezomib以及Ninlaro(Ixazomib Citrate)都是一种蛋白酶体抑制剂,能够阻断多发性骨髓瘤细胞的酶,进而阻碍其生长及生存的能力,其结构分别如下所示:

WO2012/177835公开了Ixazomib如下结构的衍生物:(代号Ixazomib DEA)
Figure PCTCN2018000027-appb-000002
虽然Ixazomib、Ixazomib-DEA对肿瘤细胞株增殖具有抑制作用,但寻求对肿瘤细胞株增殖具有更优异的抑制作用的化合物是非常有必要的。
