Description

微管蛋白抑制剂Tubulin inhibitor 技术领域Technical field

本发明也涉及制备所述化合物的中间体化合物。The invention also relates to intermediate compounds for the preparation of said compounds.

背景技术Background technique
作为肿瘤治疗的主要手段,抗肿瘤药物为延长患者的生存时间以及改善其生命质量做出了相当的贡献。其中作用于微管的药物(微管抑制剂),又在肿瘤药物中具有相当重要的地位。但是目前的临床药物,受到如下不良问题的影响:较差的水溶性,不利于给药且易造成的过敏反应、严重的毒副作用以及获得性耐药性,导致疗效降低、化学结构复杂难于合成而造成来源稀少,限制了它们进一步的使用。因而,急需寻找设计新型的微管蛋白抑制剂,尤其是结构简单的小分子抑制剂。As the main means of cancer treatment, anti-tumor drugs have made considerable contributions to prolonging the survival time of patients and improving their quality of life. Among them, drugs acting on microtubules (microtubule inhibitors) have a very important position in oncology drugs. However, the current clinical drugs are affected by the following unfavorable problems: poor water solubility, unfavorable allergic reactions, serious toxic side effects and acquired drug resistance, resulting in reduced efficacy, complicated chemical structure and difficulty in synthesis. The scarcity of sources limits their further use. Therefore, there is an urgent need to find new types of tubulin inhibitors, especially small molecule inhibitors with simple structures.
微管(microtubule)是真核细胞的重要组分,也是重要的抗肿瘤药物作用靶标。微管是细胞骨架的主要组成部分,由α-微管蛋白和β-微管蛋白异二聚体组成,具有中空管状结构的特点。此外,还有一种γ微管蛋白,它不是微管的组成成分,但参与微管的组装。Microtubules are important components of eukaryotic cells and important targets for antitumor drugs. Microtubules are the main components of the cytoskeleton. They are composed of α-tubulin and β-tubulin heterodimer and have the characteristics of hollow tubular structure. In addition, there is a gamma tubulin, which is not a component of microtubules but participates in the assembly of microtubules.
微管具有聚合和解聚的动力学特性,在细胞形态、细胞***、信号转导及物质输送等过程中起着重要作用。微管在细胞***前期聚合成为纺锤体,而纺锤体在有丝***中牵引染色体向两极移动进入两个子细胞中,完成细胞增殖。由于微管在细胞***中具有极其重要的作用,现已成为抗肿瘤药物研究的重要靶点之一。作用于微管***的微管蛋白抑制剂也已成为一类有效的抗肿瘤药物。Microtubules have the dynamic properties of polymerization and depolymerization, and play an important role in cell morphology, cell division, signal transduction and material transport. Microtubules polymerize into spindles in the early stage of cell division, and the spindle in the mitosis pulls the chromosomes into the two poles and moves into the two daughter cells to complete cell proliferation. Since microtubules play an extremely important role in cell division, they have become one of the important targets for antitumor drug research. Tubulin inhibitors acting on microtubule systems have also become an effective class of antitumor drugs.
微管蛋白抑制剂有两种分类方法。一种是根据作用机制的不同分为两种类型:①抑制微管蛋白聚合的微管蛋白解聚剂;②促进微管蛋白聚合的微管蛋白聚合剂。另一种分类方法是根据微管蛋白抑制剂与微管蛋白作用位点的不同分为3类:①作用于秋水仙碱位点的微管蛋白抑制剂;②作用于长春碱位点的微管蛋白抑制剂;③作用于紫杉醇位点的微管蛋白抑制剂。There are two classification methods for tubulin inhibitors. One is divided into two types according to the different mechanism of action: 1 tubulin depolymerization inhibitor that inhibits tubulin polymerization; 2 tubulin polymerization agent that promotes tubulin polymerization. Another classification method is divided into three categories according to the different sites of tubulin inhibitor and tubulin: 1 tubulin inhibitor acting on the colchicine site; 2 microactin acting on the vinblastine site Tubulin inhibitor; 3 tubulin inhibitor acting on the paclitaxel site.
现有研究表明,微管蛋白(tubulin)中存在三个主要的药物结合位点:紫杉醇结合位点(Taxol site)、长春碱结合位点(Vinblastine sitc)以及秋水仙碱结合位点(Colchieinesite)。但在这三个位点中,秋水仙碱位点由于自身结合腔的体积较小,有利于小分子抗肿瘤抑制剂的研究。Existing studies have shown that there are three major drug binding sites in tubulin: the Taxol site, the Vinblastine sitc, and the Colchieine site. . However, among these three loci, the colchicine site is conducive to the study of small molecule anti-tumor inhibitors due to the small volume of its own binding cavity.

通过分析研究结合位点的结构性质,并模拟其与抑制剂的结合,确定各亚区域的性质、关键作用残基以及潜在的结合部位;从抑制剂结构中的共有基团入手,逐步扩充共有基团的性质,从而假设了抑制剂的结构模板。再从活性构象出发并结合已有的构效关系研究,提出抑制剂的三维药效团模型以及影响活性的部分结构因素。在此基础上,开展新型微管抑制剂的设计、合成、结构改造以及体外活性研究。By analyzing the structural properties of the binding site and simulating its binding to the inhibitor, the properties, key functional residues and potential binding sites of each sub-region are determined; starting from the common group in the inhibitor structure, the consensus is gradually expanded. The nature of the group, thus assuming a structural template for the inhibitor. Starting from the active conformation and combining with the existing structure-activity relationship studies, the three-dimensional pharmacophore model of the inhibitor and some structural factors affecting the activity were proposed.

结果表明,上述化合物对于各考察肿瘤细胞株具有很强的抑制作用,并且与参考药物[(-)苯基阿夕斯丁](商业购买)对比,该实施例中化合物抑制肿瘤的强度远高于参考药物。结合实施例12中对不同酶的影响可以看出,本实施例中化合物发挥抑制肿瘤作用的浓度大幅度低于抑制酶的浓度,因此可以推断出本实施例中化合物在抑制肿瘤增殖时,除对本申请中提及到的酶有抑制作用外,对其他尚未考察的酶活力或细胞内分子尚有较强的抑制作用,可能会不同程度地影响多种细胞内外靶点发挥强效的协同抑制肿瘤作用。The results showed that the above compounds had a strong inhibitory effect on each of the tumor cell lines examined, and compared with the reference drug [(-)phenyl Astrastin] (commercially available), the compound in this example inhibited the tumor with a high intensity. For reference drugs. In combination with the effects of different enzymes in Example 12, it can be seen that the concentration of the compound in the present embodiment to inhibit the tumor is significantly lower than the concentration of the inhibitory enzyme, so it can be inferred that the compound of the present embodiment inhibits tumor proliferation. In addition to inhibiting the enzymes mentioned in this application, it has a strong inhibitory effect on other enzyme activities or intracellular molecules that have not been investigated, and may affect various intracellular and extracellular targets to exert strong synergistic inhibition to varying degrees. Tumor effect.
实施例14:对肿瘤的增殖的抑制作用Example 14: Inhibition of tumor proliferation
实验方法experimental method
将MES-SA人子宫肉瘤细胞(来源ATCC)长期培养于低浓度的阿霉素中,保持充分的细胞活力,诱导细胞表达p-glycoprotein。培养10个月后,利用WB检测诱导表达结果。诱导成功后,利用无阿霉素培养基培养一周后,调整细胞浓度,将肿瘤细胞接种于裸鼠腋下,并待移植肿瘤增殖到一定体积后给予不同的药物进行治疗。利用空白小鼠分别给予不同药物不同剂量摸索出不影响动物体重增长的剂量即为给予移植肿瘤动物治疗的剂量(图1)。MES-SA human uterine sarcoma cells (derived from ATCC) were cultured in low concentrations of doxorubicin for a long time to maintain sufficient cell viability and induce the expression of p-glycoprotein. After 10 months of culture, the expression results were induced by WB detection. After successful induction, after one week of culture without doxorubicin medium, the cell concentration was adjusted, and the tumor cells were inoculated into the armpit of nude mice, and the transplanted tumors were proliferated to a certain volume and then treated with different drugs. The doses of different doses of different drugs were used to explore the doses that did not affect the body weight gain of the animals, which was the dose to be treated for the transplanted tumor animals (Fig. 1).
结果表明,在给予不会降低动物体重的剂量下,不同的药物对于裸鼠移植肿瘤抑制率具有一定的差异。其中(-)苯基阿夕斯丁在无毒剂量下几乎单独使用无对抗肿瘤增殖的效果。而多西他赛(商业购买)在无明显毒性该剂量下药效作用较差。化合物9、化合物11、化合物15、化合物18在对动物体重增殖无明显影 响的剂量下能有效地发挥抗肿瘤增殖的作用。The results showed that different drugs had different degrees of tumor inhibition rate in nude mice when administered at a dose that did not reduce the body weight of the animals. Among them, (-) phenyl azantin was used almost independently at a non-toxic dose without an effect against tumor proliferation. Docetaxel (commercially purchased) has a poorer pharmacological effect at doses that are not significantly toxic. Compound 9, Compound 11, Compound 15, and Compound 18 have no significant effect on animal body weight proliferation. The anti-tumor proliferation effect can be effectively exerted at a loud dose.
肿瘤抑制率(%)=(1-治疗组瘤重量/对照组瘤重量)*100%,根据图1所示,多西他赛的肿瘤抑制率接近80%,并且高于化合物9、化合物11、化合物15、化合物18。Tumor inhibition rate (%) = (1 - treatment group tumor weight / control tumor weight) * 100%, according to Figure 1, the tumor inhibition rate of docetaxel is close to 80%, and higher than compound 9, compound 11 , Compound 15, Compound 18.
本实施例中同时测试了在同等药效剂量下,药物对于不同组织器官血流分布的影响。给药后2小时,多西他赛组中包含肿瘤组织在内,血流的分布与空白溶媒组类似。而化合物9、化合物11、化合物15、化合物18以及(-)苯基阿夕斯丁对除肿瘤组织外的其他组织未发现有明显的干预组织血流分布的影响。对于肿瘤组织,化合物9、化合物11、化合物15、化合物18以及(-)苯基阿夕斯丁组与空白溶媒组比较,能显著降低肿瘤内血流分布。In this example, the effects of drugs on blood flow distribution of different tissues and organs at the same pharmacodynamic dose were simultaneously tested. Two hours after the administration, the distribution of blood flow including the tumor tissue in the docetaxel group was similar to that of the blank vehicle group. However, Compound 9, Compound 11, Compound 15, Compound 18, and (-) phenyl azantin did not significantly affect the distribution of blood flow in tissues other than tumor tissues. For tumor tissues, Compound 9, Compound 11, Compound 15, Compound 18, and (-) phenyl Axantine group significantly reduced intratumoral blood flow distribution compared with the blank vehicle group.
实施例15:化合物的抗肿瘤作用以及安全性Example 15: Antitumor effect and safety of compounds
对接种肿瘤细胞的裸小鼠分别给以空白溶媒、多西他赛、化合物9以及多西他赛与化合物9联合药物,于给药后不同的时间点测量肿瘤的体积并检测肿瘤体积变化过程,同时检测裸小鼠的体重变化,以评价药物的抗肿瘤效果以及毒性反应程度。另对正常SD大鼠,按照以上给药与分组方式,在给药前以及末次给药后检测血中性粒细胞计数水平,以评价药物对于中性粒细胞计数的影响程度。The nude mice inoculated with tumor cells were given blank vehicle, docetaxel, compound 9 and docetaxel and compound 9 in combination, and the tumor volume was measured at different time points after drug administration and the tumor volume change process was detected. At the same time, the change in body weight of nude mice was examined to evaluate the antitumor effect and the degree of toxicity of the drug. In addition, in normal SD rats, blood neutrophil counts were measured before and after the administration according to the above administration and grouping methods to evaluate the degree of influence of the drug on neutrophil counts.
实验结果表明,化合物9在体内能有效地抑制肿瘤的增殖,同时与多西他赛联合使用后能显著增加抗肿瘤活性,同时有效地降低了多西他赛单独应用时的整体不良反应,能显著降低多西他赛毒性引起的动物体重降低。在正常大鼠体内联合使用多西他赛与化合物9后,与单独使用多西他赛比较,中性粒细胞计数显著升高,有效地抑制了多西他赛引起的中性粒细胞计数降低的不良反应。综合比较,在不影响动物整体状态的剂量下,化合物9对抗肿瘤的效果显著优于多西他赛,即化合物9的肿瘤治疗窗显著地优于多西他赛,同时为进一步增加抗肿瘤效果,将多西他赛与化合物9联合应用能有效地降低多西他赛毒性反应,并增加抗肿瘤作用(图2)。The results showed that Compound 9 can effectively inhibit the proliferation of tumors in vivo, and it can significantly increase the anti-tumor activity when combined with docetaxel, and effectively reduce the overall adverse reactions of docetaxel alone. Significantly reduced animal weight loss caused by docetaxel toxicity. After the combination of docetaxel and compound 9 in normal rats, the neutrophil count was significantly increased compared with docetaxel alone, effectively inhibiting the decrease in neutrophil count caused by docetaxel. Adverse reactions. In a comprehensive comparison, the effect of Compound 9 against tumors was significantly better than that of docetaxel at doses that did not affect the overall state of the animal, that is, the tumor treatment window of Compound 9 was significantly better than docetaxel, and further increased the anti-tumor effect. The combination of docetaxel and Compound 9 can effectively reduce the toxicity of docetaxel and increase the anti-tumor effect (Figure 2).
实施例16:对中性粒细胞计数的影响Example 16: Effect on neutrophil count
实验方法experimental method
利用多剂量分别给予不同的药物对裸鼠移植肿瘤的抑制程度考察,摸索出各个药物的等效剂量,并通过物种间剂量折算后给予大鼠不同药物。即在给予大鼠相对同等药效学剂量下,考察药物对于大鼠中性粒细胞计数的影响。连续给予Wista大鼠2周后,对大鼠采血并称量各个给药组体重(图3)。The multi-dose was given different drugs to inhibit the degree of tumor xenografting in nude mice, and the equivalent dose of each drug was explored, and different drugs were given to rats by the inter-species dose conversion. That is, the effect of the drug on neutrophil count in rats was examined under the dose of the same pharmacodynamic dose to the rats. Two weeks after the continuous administration of Wistar rats, the rats were bled and the body weights of the respective administration groups were weighed (Fig. 3).
结果表明,在同等药效剂量下,连续使用各个化合物给予大鼠后,常规抗肿瘤药物多西他赛能显著降低大鼠体内中性粒细胞计数,同时实验中观察到动物整体状态不佳。(-)苯基阿夕斯丁与多西他赛相比,在同等药效学剂量下对中性粒细胞降低作用轻于多西他赛,但是中性粒细胞计数仍显著低于空白溶媒组与 化合物组。而化合物9、化合物11、化合物15、化合物18组在与其他药物同等药效剂量下,对中性粒细胞无显著影响。因此,化合物9、化合物11、化合物15、化合物18在有效对抗肿瘤增殖时,能有效避免对中性粒细胞降低的不良反应。动物体重的变化趋势与中性粒细胞计数变化百分率呈正相关。The results showed that the conventional antitumor drug docetaxel significantly reduced the neutrophil count in rats after continuous administration of each compound to the rats at the same pharmacodynamic dose. At the same time, the overall state of the animals was observed to be poor. (-) Phenyl axantine has a lower effect on neutrophils than docetaxel at the same pharmacodynamic dose compared with docetaxel, but neutrophil counts are still significantly lower than blank media Group and Compound group. The compound 9, compound 11, compound 15, and compound 18 had no significant effect on neutrophils at the same pharmacological dose as other drugs. Therefore, Compound 9, Compound 11, Compound 15, and Compound 18 can effectively prevent adverse reactions to neutrophil reduction when they are effective against tumor proliferation. The trend of animal body weight was positively correlated with the percentage change of neutrophil count.

在所述HuVEC细胞中,暴露于化合物9、11、15、18、叔丁基苯基阿夕斯丁或秋水仙碱(均为2μM)30分钟,诱导了与DMSO对照中观测结果相对的微管解聚作用(表现为缺乏完整的微管结构)和细胞膜起疱(blebbing)(细胞凋亡的明显标志),而紫杉醇在这些条件下不能诱导微管解聚作用。秋水仙碱是已知的微管解聚试剂而紫杉醇是微管素稳定剂。将CCD-27sk细胞暴露于化合9、11、15、18或秋水仙碱可观察到类似的结果。In the HuVEC cells, exposure to compounds 9, 11, 15, 18, tert-butylphenyl arstin or colchicine (both 2 μM) for 30 minutes induced a microscopic relative to the observations in the DMSO control. Tube depolymerization (expressed as a lack of intact microtubule structure) and cell membrane blebbing (a clear hallmark of apoptosis), whereas paclitaxel does not induce microtubule depolymerization under these conditions. Colchicine is a known microtubule depolymerization reagent and paclitaxel is a microtubule stabilizer. Similar results were observed when CCD-27sk cells were exposed to compounds 9, 11, 15, 18 or colchicine.
