Definitions

  • the invention belongs to the field of medicine, and in particular relates to a boric acid and a boric acid ester compound, a preparation method thereof and use thereof.
  • MM Multiple myeloma
  • MM is a plasma cell carcinoma found in the bone marrow.
  • a group of plasma cells or myeloma cells
  • cancer cells are transformed into cancer cells and proliferate, resulting in a higher than normal number of plasma cells.
  • plasma cells migrate extensively in the body, it is likely to involve most of the bones in the body, which may lead to compression fractures, osteolytic lesions and related pain.
  • Multiple myeloma can cause several serious health problems, involving red blood cell counts in the bones, immune system, kidneys, and individuals. Some of the more common symptoms include bone pain and fatigue, and fatigue is a symptom of anemia.
  • Multiple myeloma is a rare cancer, with approximately 114,000 new cases worldwide each year.
  • proteasome is a protease complex with multiple catalytically active sites responsible for the degradation of most proteins in cells including cell cycle regulatory proteins and apoptotic proteins.
  • proteasome inhibitors Preclinical studies have shown that proteasome inhibitors have the effects of inducing apoptosis and sensitizing radiotherapy. Interestingly, studies have found that cells that undergo malignant transformation are more sensitive to proteasome inhibitors than non-malignant cells. Therefore, inhibition of the proteasome becomes a promising approach to tumor therapy.
  • Proteasome inhibitors have antitumor effects in part by down-regulating nuclear factor kappa B (NF ⁇ B) or regulating cyclin and apoptotic pathways.
  • NF ⁇ B nuclear factor kappa B
  • Boric acid proteasome inhibitors currently available for the treatment of multiple myeloma include bortezomib and esamizomib.
  • Bortezomib is a reversible inhibitor of the chymotrypsin-like activity of the 26S proteasome in mammalian cells. It was marketed on May 19, 2003 by the FDA for rapid review and sold under the trade name of Velcade.
  • the formulation type is powder.
  • Esazami preferentially binds to and inhibits the activity of the ⁇ 5 subunit of the chymotrypsin-like 20S proteasome, which was approved by the FDA on November 20, 2015, and esamizol citrate in combination with lenalidomide and ground.
  • Dexamethasone is used in MM patients who have previously received at least one treatment regimen, the formulation type being capsules.
  • Oral esamizomib has a distinct advantage over the injected bortezomib in the route of administration. However, the absolute oral bioavailability was only 58% based on the population PK analysis mean. Clinically, esamizomi still has toxic side effects such as diarrhea, constipation, thrombocytopenia, peripheral neuropathy, nausea, peripheral edema, and vomiting.

Description

硼酸和硼酸酯类化合物及其制备方法和用途
本申请要求申请日为2017年4月26日的中国专利申请CN201710284493.X的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属于医药领域,具体地涉及一种硼酸和硼酸酯类化合物及其制备方法和用途。
背景技术
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,疲乏是贫血的症状。多发性骨髓瘤属罕见癌症,全球每年新发病例约11.4万例。
蛋白酶体是具有多催化活性位点的蛋白酶复合体,负责包括细胞周期调控蛋白和细胞凋亡蛋白在内的细胞内绝大多数蛋白质的降解。临床前研究显示蛋白酶体抑制剂具有诱导细胞凋亡、化放疗增敏等作用。十分有趣的是,研究发现发生恶性转化的细胞对蛋白酶体抑制剂比非恶性细胞更为敏感。因此,抑制蛋白酶体成为一种很有希望的肿瘤治疗途径。蛋白酶体抑制剂部分通过下调核因子κB(NFκB)或者调控细胞周期蛋白和细胞凋亡通路而具有抗肿瘤作用。
目前已经上市的用于治疗多发性骨髓瘤的硼酸类蛋白酶体抑制剂有硼替佐米和埃沙佐米。硼替佐米是哺乳动物细胞中26S蛋白酶体糜蛋白酶样活性的可逆抑制剂,于2003年5月19日通过美国FDA的快速审查,以Velcade(万珂)商品名上市销售,制剂类型为粉剂。埃沙佐米优先结合和抑制胰凝乳蛋白酶-样20S蛋白酶体的β5亚单位的活性,于2015年11月20日由FDA批准上市,埃沙佐米柠檬酸酯联合来那度胺和地塞米松用于既往已接受过至少一种治疗方案的MM患者,制剂类型为胶囊。
在给药途径上,口服的埃沙佐米相对注射的硼替佐米有了非常明显的优势。然而,根据群体PK分析均数绝对口服生物利用度仅为58%。临床上埃沙佐米仍然存在腹泻,便秘,血小板减少,外周神经病变,恶心,外周水肿,呕吐等毒副作用。
因此,本领域仍需要开发对多发性骨髓瘤有更好药效学性能和药物动力学性能的化 合物。
发明内容
本发明的目的是提供一类具有蛋白酶体抑制作用的硼酸和硼酸酯类化合物及其制备方法和用途。本发明意外地发现,本发明所提供的氘代硼酸或硼酸酯类化合物与相应的非氘代的化合物相比,具有明显更优异的药效学性能和药物动力学性能,具体地体现在药物半衰期和生物利用度上有了非常显著的提高,因此更适合作为蛋白酶体抑制剂,进而更适用制备治疗蛋白酶体相关疾病的药物。在此基础上完成了本发明。

实施例40:体外活性测试
检测化合物对细胞水平的蛋白酶体亚单位CTL的活性抑制:
细胞培养
培养基:MEM培养基(Gibco,11095-080)+10%FBS
培养条件:37℃,5%CO 2
首先,取对数生长期的Calu-6细胞(中科院细胞,TCHu144),用胰酶消化,新鲜培养基重悬后,按照每孔2000个细胞的密度铺入384孔细胞培养板(Cat.3707,Corning),每孔20μL细胞培养液,背景信号孔中加入20μL培养基(不含细胞),放入培养箱继续 培养过夜。
用DMSO将待测化合物稀释至2mM,然后3倍倍比稀释,共10个浓度点。再用新鲜的培养基将梯度稀释的化合物稀释40倍,DMSO浓度为2.5%。
向样品孔中加入5μL稀释好的化合物。待测化合物起始浓度为10μM,3倍倍比稀释。全活对照孔和背景信号孔中加入等体积的溶媒(2.5%DMSO),最终体系中DMSO浓度为0.5%。
继续培养2hr后,每孔加入25μL Proteasome-Glo TM Cell-Based Reagent(Promega,G1200),振荡10min,用酶标仪(PE,envision 2104)读取Luminescence。
通过全活性孔(没有加入待测化合物)和背景信号孔(没有细胞)计算出每个孔的抑制率,复孔取平均值,同时用专业的画图分析软件PRISM 5.0对每个待测化合物进行抑制率的图示。
抑制率用以下公式计算:
抑制率=(RLU 100%-RLU sample)/(RLU 100%-RLU background)100%
结果如表3所示。结果表明:与对照化合物Im或IIm相比,本发明的化合物对Calu-6细胞蛋白酶体CT-L活性的抑制能力相似。

实施例41:大鼠的药代动力学评价
从上海西普尔-必凯实验动物有限公司购入雄性SPF级体检合格、无异常的健康SD大鼠。经颈静脉穿刺采血,每个样品采集约0.2mL,肝素钠抗凝,采血时间点如下:
给药前,给药后5min,15min,30min,1h,2h,4h,6h,8h,24h和48h。
血液样本采集后置于冰上,离心分离血浆(离心条件:8000转/分钟,6分钟,2-8℃)。收集的血浆分析前存放于-80℃。
血液样品由实验机构分析部门采用LC-MS/MS进行分析。
根据药物的血药浓度数据,使用药代动力学计算软件WinNonlin5.2非房室模型分别计算供试品的药代动力学参数AUC 0-∞、MRT 0-∞、Cmax、Tmax、T 1/2和Vd等参数及其平均值和标准差。此外,生物利用度(F)将通过下面的公式进行计算。
F=(AUC (0-∞)(PO)×Dose (IV))/(AUC (0-∞)(IV)×Dose (PO))×100%
对于浓度低于定量下限的样品,在进行药代动力学参数计算时,在达到Cmax以前取样的样品应以零值计算,在达到Cmax以后取样点样品应以无法定量(BLQ)计算。
氘代化合物和非氘代化合物的药代动力学参数如下表4和表5。根据实验结果可知,本发明的氘代化合物Ic、Ia,与相应的非氘代化合物Im相比,药物体内半衰期、AUC和生物利用度都有非常明显的提高。其中化合物Ic的半衰期提高了至少70%,生物利用度提高了至少80%。而化合物Ie的药物体内半衰期和生物利用度与非氘代化合物Im接近,其AUC小于非氘代化合物Im。这说明只有合适位点上的氢被氘取代才可能取得更好的药代动力学效果,这需要大量的合成工作和生物评价工作,才能筛选出比相应的非氘代化合物更加优异的药物获选化合物。

PO(1mg/Kg)。
从表5实验数据可以看出,本发明的氘代化合物IIc、IIa,与相应的非氘代化合物IIm相比,药物体内半衰期、AUC都有非常明显的提高。而化合物IIe的药物体内半衰期和AUC与非氘代化合物IIm接近。同样说明对化合物氘代位点选择的重要性和复杂性,通过氘代改善化合物的药代动力学不是显而易见的,而是需要合成大量的氘代化合物以及生物评价工作,才能筛选出比相应的非氘代化合物更加优异的药物获选化合物。
