Description
技术领域
本发明涉及一种新的羟戊苯甲酸双酯类化合物,具体涉及双分子右崁醇与2-(α-羟基正戊基)苯甲酸(即开环丁苯酞)的拼合化合物及其制备方法以及在制备药物中的应用。
背景技术
脑卒中是由脑组织缺血、缺氧所引起的一种急性脑血管性疾病,主要分为缺血性和出血性两大类,其中缺血性脑卒中占约70%以上,具有很高的发病率、死亡率和致残率,严重危害人类的健康和生命。目前对缺血性脑卒中的药物治疗手段主要有两种,一是利用溶栓、抗血小板聚集、抗凝和降纤药物,二是利用神经保护药物减轻由于缺血而导致的神经细胞损伤或凋亡。近年来,血管内血栓切除术对急性缺血性脑卒中的治疗显示出巨大的价值,然而很少有脑卒中患者能够获得这种治疗,且仅有不到一半的患者能够永久受益。组织型纤溶酶原激活剂阿替普酶(alteplase)是美国FDA批准治疗急性缺血性脑卒中的唯一药物,但其存在治疗窗口窄、易产生出血性不良反应且无神经保护活性等问题,应用受到限制,因此研发出一类具有改善脑部供血功能且有一定神经保护的药物对于治疗缺血性脑卒中具有重要意义。
丁苯酞(3-n-nutylphthalide,NBP,下式A)是从芹菜籽中提取出的一种苯并呋喃酮类化合物,其化学名为(R/S)-3-正丁基-1(3H)-异苯并呋喃酮。NBP是我国自主研发并于2002年上市用于治疗缺血性脑卒中的药物,在《中国急性缺血性脑卒中治疗指南2018》中NBP被定义为“改善脑血循环的药物”。NBP具有抗血小板聚集、抗血栓、减少脑梗死体积、改善脑微循环等多种生物活性。尽管NBP能对脑缺血的多个病理环节有治疗作用,但NBP水溶性极差,为改善其水溶性与活性,现已有通过手性拆分、在苯环上引入取代基、内酯开环后再衍生等方法对NBP进行结构修饰与改造。2-(α-羟基正戊基)苯甲酸为NBP的内酯开环产物,具有与NBP类似的生物活性和药代动力学特征,但是其在体内外均不稳定,难以制备成适合临床应用的药物。NBP因其自身的疗效有限,在临床上常与其它药物联用以增强其疗效,如CN107595874A中将丁苯酞与甲钴胺联合用药,以增加丁苯酞的治疗效果,从而降低丁苯酞起效剂量,减少用药量,长期应用降低不良反应的发生。
A:丁苯酞(NBP);B:右崁醇((+)-冰片)
右崁醇,即右旋崁醇(上式B)常由樟科植物的新鲜枝、叶提取加工而成,为双环单萜类化合物,又名(+)-冰片,有醒脑通窍、促进药物透过血脑屏障、保护心脑血管、防止血栓、镇痛抗炎、抗菌等作用。现代药理学研究表明,冰片可通过抑制转运蛋白外排、调节生物化学物质水平、改变皮肤角质层的结构及调整内皮细胞连接结构等提高心脑血管系统药物浓度、促进血脑屏障开放,因此常与其它药物配伍显著延长有效药物保留时间,提高药效,如CN105267212A中将依达拉奉与右旋崁醇组合物用于治疗心脑血管疾病的药物。专利申请CN113402543A曾试图改造丁苯酞,但其改造后的新化合物相对于丁苯酞的有效性未见明显提升,两者效果之间无统计学差异,难以制备成适合临床应用的药物。为了开发更多的治疗心脑血管疾病的药物,本发明人团队进行了锐意研究。
发明内容
基于丁苯酞与右崁醇均有改善脑循环和保护心脑血管的作用,本团队采用层层递进式的预实验,首先将丁苯酞与右崁醇进行1:1(摩尔比)简单组合形成组合物,发现该组合物采用体内注射或口服给药时,与单用丁苯酞或者右崁醇相比,降低大脑中动脉栓塞(MCAO)模型大鼠的脑梗死面积的效果并不明显;在此基础上,我们探索性地将丁苯酞开环产物与右崁醇进行1:1(摩尔比)拼合形成新的化合物(如下式B),发现该化合物活性仅略有提高;进一步地,我们将丁苯酞开环产物与右崁醇进行1:2(摩尔比)拼合,发现被两分子右崁醇取代的2-(α-羟基正戊基)苯甲酸衍生物(如下式C)的活性明显优于一分子右崁醇取代的2-(α-羟基正戊基)苯甲酸衍生物(如下式B)。此外,本发明深入考察了手性构型对活性的影响,发现在同样的两分子右崁醇取代的2-(α-羟基正戊基)苯甲酸衍生物中,左旋化合物(如下式D)的活性更优。
A:丁苯酞与右崁醇组合物(1:1);B:丁苯酞与右崁醇拼合物(1:1);C:丁苯酞与右崁醇拼合物(1:2);D:左旋丁苯酞与右崁醇拼合物(1:1)
本申请通过将丁苯酞或左旋丁苯酞的开环产物与右崁醇在特定比例下进行拼合反应,获得一系列两分子右崁醇取代的2-(α-羟基正戊基)苯甲酸衍生物,所述衍生物通过右崁醇的促进药物透过血脑屏障的功能,提高了丁苯酞开环产物在脑血管中的药物浓度,能够发挥拼合药物多靶点、多通路的协同脑保护功效。本发明通过抗脑缺血体内药效学MCAO/R模型大鼠的脑梗死面积的活性评价,获得了高活性的临床候选药物,且合成方法能够实现工业化生产。本发明通过将丁苯酞的内酯环开环产物与双分子右崁醇进行拼合反应获得一系列羟戊苯甲酸双酯化合物,实现了对丁苯酞的结构优化,能显著提高丁苯酞的抗脑缺血效果。
本发明的羟戊苯甲酸双酯化合物在临床上具有积极的治疗价值,且成药性明显,值得深入开发。
本发明的羟戊苯甲酸双酯化合物的结构通式如下:
X= H、硝基、氨基、F、Cl、Br或I。

a、将丁烯基苯酞或取代的丁烯基苯酞类物质(R-1),经催化氢化(钯碳、兰尼镍等)将双键还原,得到丁苯酞或取代的丁苯酞外消旋体(R-2)。
b、R-2经强碱水解(氢氧化钠、氢氧化钾等与R-2的摩尔比5:1~1:1),反应条件:1)加热反应,温度为20 ℃~120 ℃,1 h~5 h;2)或微波反应,温度20 ℃~60 ℃,30 min~1 h。反应结束后用稀酸调pH并用乙酸乙酯、乙醚等萃取浓缩得到中间体R-3。R-3依次与丁二酸酐(与R-2摩尔比为5:1~1:1)、DMAP和Et3N(与R-2摩尔比为5:1~1:1)混合反应得到R-4。
c、R-4经由DCC(与R-4摩尔比为10:1~2:1)催化,与右崁醇发生缩合反应(右崁醇与R-4摩尔比为10:1~2:1),得到目标产物R-5。
路线二:
化合物R-2利用化学手性拆分得到手性化合物L-1后,利用上述步骤b~c即可得到目标产物L-4。

药效学实验:NBP衍生物(实施例1的化合物1和实施例2的化合物2)对脑缺血再灌注损伤的防治作用研究
一、 实验方法:
1. 实验分组:
SHAM组:假手术组
大脑中动脉栓塞(MCAO)模型组
丁苯酞(NBP): 5 mg/kg
左旋丁苯酞(L-NBP):2.5 mg/kg
NRB(化合物1):15 mg/kg(通过折算,与NBP 4.9 mg/kg的剂量相当)
L-NRB(化合物2)低剂量:7.5 mg/kg(通过折算,与L-NBP 2.45 mg/kg的剂量相当)
L-NRB(化合物2)高剂量:15 mg/kg(通过折算,与L-NBP 4.9 mg/kg的剂量相当)
阿司匹林组(ASP):10 mg/kg
2. 给药方法:
造模前连续腹腔给药5天,假手术组和MCAO模型组大鼠给予等量生理盐水,随后进行MCAO手术。
大脑中动脉栓塞(MCAO)模型制作:
采用线栓法制作大脑中动脉栓塞(MCAO)模型,手术过程严格无菌操作,主要手术过程如下:水合氯醛腹腔注射麻醉大鼠,分离出颈总动脉(CCA)、颈外动脉(ECA)和颈内动脉(ICA),用微动脉夹夹闭颈总动脉,用双极电凝笔电凝颈外动脉的分支。游离颈外动脉主干,在距颈总动脉分叉3~4 mm 处结扎。微动脉夹暂时夹闭颈内动脉,眼科剪将颈外动脉剪一小口,插入甲聚硅氧烷涂布的4-0单丝尼龙线,在颈外动脉剪口处打一松节以阻断颈内动脉的血液返流,去除颈内动脉的微动脉夹,轻推尼龙线进入颈内动脉,到达颅内的大脑前动脉,阻断大脑中动脉(MCA)的开口,插入深度约18-22 mm。去除颈总动脉的微动脉夹,消毒后逐层缝合皮下组织和皮肤,于术后2 h缓慢抽出尼龙线进行再灌注。假手术组除了不插入尼龙线外,其它一切操作相同。所有大鼠在整个实验过程中的直肠温度维持在37 ℃。
二、检测指标:
1. 神经功能评价:
于再灌注24小时后,按照Longa 5级评分方法对所有大鼠进行神经行为评分。Longa评分标准: 0,正常,无神经功能缺损;1, 左前肢伸展障碍,功能减弱;2,向左打圈,左前肢瘫痪,功能严重减弱, 提起大鼠尾巴后,大鼠不停的扭向受损区; 3, 行走时向左侧倾倒;4, 肢体瘫痪,意识昏迷。
脑梗死面积测定:
于再灌注24小时后,采用四氮唑红(TTC)染色测定脑梗死面积。大鼠断颈处死,迅速取出全脑,置于-20 ℃冰箱短暂冷冻后,置于冰盘上去掉嗅球,将前脑沿冠状面切成厚度为2 mm的6片,将脑片置于1.5 mL 2% TTC溶液中避光孵育30 min,再将脑片置 10%多聚甲醛中固定过夜,再进行拍照分析。使用Image-J软件对脑梗塞体积进行测量计算。
三、实验结果
1. 神经功能评分
模型组神经功能评分显著高于假手术组;各给药组神经学评分显著低于模型组(p<0.05);与NBP组相比,NRB组(p<0.05)、L-NRB低剂量组(p<0.05)和L-NRB高剂量组(p<0.01)显著降低 (图29,表1 )。
表1 NBP衍生物对MCAO/R模型大鼠神经功能评分的影响.
##,P<0.01 vs 假手术组;**,P<0.01 vs MCAO/R模型组;$,P<0.05 vs NBP组;$$,P<0.01 vs NBP组; &,P<0.01 vs L-NBP组.
2. 脑梗死面积
模型组脑梗死面积显著高于假手术组;各给药组脑梗死面积显著低于模型组(p<0.05);与NBP组相比,NRB组(p<0.05)、L-NRB低剂量组(p<0.05)和L-NRB高剂量组(p<0.01)显著降低 (图30,图31,表2)。所评价的衍生物降低脑梗死面积的评价结果与其改善神经功能评分的结果一致。
表2 NBP衍生物对MCAO/R模型大鼠的脑梗死面积的影响.
##,P<0.01 vs 假手术组;**,P<0.01 vs MCAO/R模型组;$,P<0.05 vs NBP组;$$,P<0.01 vs NBP组; &&,P<0.01 vs L-NBP组。
四、实验结论
以改善脑梗死面积评价结果为例:
1、 与模型组相比,NBP组(5 mg/kg即0.026 mmol/kg)、L-NBP组(2.5 mg/kg即0.013 mmol/kg)、NRB组(15 mg/kg即0.026 mmol/kg)、L-NRB低剂量组(7.5 mg/kg即0.013mmol/kg)、L-NRB高剂量组(15 mg/kg即0.026 mmol/kg)均表现出改善脑梗死面积活性,梗死抑制率(相对于模型组)分别为34.2%、46.4%、63.7%、62.0%、77.6%,且具有显著性差异,该结果表明:本发明所合成的羟戊苯甲酸双酯化合物均具有良好的治疗脑缺血的活性,且效果显著优于丁苯酞和左旋丁苯酞。
2、 与NBP组相比,L-NBP组、NRB组、L-NRB低剂量组、L-NRB高剂量组均表现出改善脑梗死面积活性,抑制有效率(相对于NBP组)分别为18.6%、44.8%、42.3%、66.0%,且NRB组、L-NRB低剂量组、L-NRB高剂量组与NBP组之间均具有显著性差异,该结果表明:1)左旋构型的丁苯酞或衍生物,活性均优于其对应的消旋物;2)连接2个右崁醇的丁苯酞衍生物的活性优于丁苯酞原型化合物。
3、 与L-NBP组相比,L-NRB低剂量组、L-NRB高剂量组均表现出明显的改善脑梗死面积活性,抑制有效率(相对于L-NBP组)分别为29.1%、58.2%,且L-NRB低剂量组、L-NRB高剂量组与L-NBP组之间均具有显著性差异,该结果表明连接2个右崁醇的左旋丁苯酞活性优于左旋丁苯酞原型化合物。
4、与模型组相比,ASP组可表现出改善脑梗死面积活性,同样表明模型组建立成功;与ASP组(10 mg/kg即0.56 mmol/kg)相比,L-NRB高剂量组表现出显著的改善脑梗死面积活性,抑制有效率为56.6%,表明本发明所涉及的羟戊苯甲酸双酯化合物,具有很好的改善脑梗死面积和神经功能作用,明显优于临床常用药物阿司匹林的活性,在临床上具有积极的治疗作用,且成药性明显,值得深入开发。
