Description
本发明涉及海鞘素衍生物、特别是海鞘素736(ET-736)、包含它们的药用组合物以及它们作为抗肿瘤化合物的用途。
发明背景
海鞘素是从海洋被囊动物Ecteinascidia turbinata分离的非常有效的抗肿瘤药。在以前的专利和科学文献已经报道了几种海鞘素。
参见例如:
美国专利5.256.663介绍了包含从热带海洋无脊椎动物Ecteinascidia turbinata提取的物质的药用组合物,所述物质在该专利中称为海鞘素,并且介绍了这样的组合物用作哺乳动物的抗菌、抗病毒和/或抗肿瘤药。
美国专利5.089.273介绍了介绍了从热带海洋无脊椎动物Ecteinascidia turbinata提取的物质的新药用组合物,所述物质在该专利中称为海鞘素729、743、745、759A、759B和770。这些化合物用作哺乳动物的抗菌和/或抗肿瘤药。
美国专利5.149.804介绍了从加勒比海被囊动物Ecteinascidiaturbinata分离的海鞘素722和736(Et′s 722和736)以及它们的结构。Et′s 722和736在体内以非常低的浓度保护小鼠治疗P388淋巴瘤、B16黑素瘤和Lewis肺癌。
美国专利5.478.932介绍了从加勒比海被囊动物Ecteinascidiaturbinata分离的海鞘素,该化合物提供体内保护治疗P388淋巴瘤、B16黑素瘤、M5076卵巢肉瘤、Lewis肺癌以及LX-1人肺癌和MX-1人乳腺癌的异种移植物。
美国专利5.654.426介绍了从加勒比海被囊动物Ecteinascidiaturbinata分离的几种海鞘素,这些化合物提供体内保护治疗P388淋巴瘤、B16黑素瘤、M5076卵巢肉瘤、Lewis肺癌以及LX-1人肺癌和MX-1人乳腺癌的异种移植物。
美国专利5.721.362介绍了生成海鞘素化合物的合成方法以及相关结构。
美国专利6.124.292介绍了系列新的海鞘素样化合物。

国际专利申请WO 0069862公开了化合物36(一种在氰基番红菌素B转化为海鞘素743过程中的中间体)。
这种半合成的中间体用作合成海鞘素736的初始原料,海鞘素736是具有有效抗肿瘤治疗活性的天然海鞘素家族的又一成员。
以下反应流程介绍制备海鞘素736和在四氢-β-咔啉单元和位置18(-OR4)具有不同取代基的相关化合物的优选方法。
流程1
如流程1的示例性描述,中间体36可以分两步转化为ET-736(或取代的衍生物)。
第一步是从化合物36制备本发明优选的I型化合物,将其与相应的伯胺或仲胺反应引入四氢-β-咔啉单元。
第二步是与硝酸银在ACN/H2O中反应将CN基团转化为OH基团。
也可能用优选的化合物I通过酰化或烷基化反应获得具有不同取代基(-OR4,18位以及=NR5)的新衍生物。在所有上述情况下,初始原料中的R1和R2为氢原子。用相同的中间体并通过与烯丙基溴的烷基化反应或者通过与氯甲酸乙烯酯的酰化反应,可以获得N和O烯丙基化的衍生物以及N和O乙烯基化的衍生物。所有这些化合物通过与硝酸银反应获得其中CN基团转化为OH基团的终产物。
熟练技术人员很容易理解,此处介绍的反应流程可以如下修改:通过使用许多取代的伯胺生产一系列取代的海鞘素736衍生物,因此,这样产生的化合物也被认为是本发明的一部分。
特别地,可以变化反应条件以适合在四氢-β-咔啉单元中各取代基团的其它组合。
以下反应流程介绍制备海鞘素694和在5位及18位(-OR6和-OR7)具有不同取代基的相关化合物的优选方法。
流程2
在流程2中,在碱性条件下C-5的乙酰基的水解使得制备出在此位置具有羟基的中间体。用此化合物通过与酸酐、酰基氯或羧酸的酰化反应,制备单-O取代以及单和二-O取代(在C-5和C-18)的新衍生物。将CN基团转化为OH的反应在典型条件(硝酸银的CH3CN/H2O溶液)下进行。在另一方面,可以用Et-736通过在KOH/MeOH存在下进行C-5的乙酰基水解获得Et-694。
熟练技术人员很容易理解,此处介绍的反应流程可以如下修改:通过使用许多取代的伯胺生产一系列取代的海鞘素736-CN衍生物,因此,这样产生的化合物也被认为是本发明的一部分。
特别地,可以变化反应条件以适合在四氢-β-咔啉单元以及C-5和C-18位上取代基团的其它组合。
本发明将根据以下帮助理解的实施例进一步说明,但是它们不应该解释为对本发明的限制。

比色测定细胞生长抑制作用
使用磺基碱性蕊香红B(SRB)反应的比色类型测定已经用作定量检测细胞生长和存活力[按照Philip Skehan等介绍的技术进行,(1990),New colorimetric cytotoxicity assay for anticancer drugscreening,J.Natl.Cancer Inst.,82:1107-1112]。
此检测类型使用9mm直径的96孔细胞培养微板(Faircloth,1988;Mosmann,1983)。大部分细胞系衍生自人的不同癌症类型,从American Type Culture Collection(ATCC)获得。
细胞维持在RPMI 1640 10% FBS,其中补充0.1g/l青霉素和0.1g/l硫酸链霉素,然后在37℃、5%CO2和98%湿度下温育。对于各实验,用胰蛋白酶从已伸展但未汇合的培养物中收获细胞,在平板接种前重新悬浮于新鲜培养基中。
以5×103细胞/孔将细胞接种到96孔微滴定板的195μl等分量培养基,允许它们在没有药物的培养基中生长18小时以附着到板表面。然后,将溶于DMSO/EtOH/PBS(0.5∶0.5∶99)浓度范围为10-10-8μg/ml的5μl等分量样品加入。在接触48h后,抗癌效果用SRB法检测:加入50μl冷50%(wt/vol)三氯乙酸(TCA)固定细胞,在4℃温育60min。将板用去离子水洗涤,然后干燥。将100μl SRB溶液(0.4%wt/vol在1%乙酸中)加入各微滴定孔,在室温下温育10min。用1%乙酸洗涤除去未结合的SRB。风干板,用Tris缓冲液溶解结合染剂。在490nm一种波长用自动分光光度板阅读器读取光学密度。
计算一式三孔数据的平均+/-SD值。细胞反应的某些参数可以被计算:GI=生长抑制作用,TGI=总的生长抑制作用(细胞生长抑制作用)和LC=杀死细胞作用(细胞毒素作用)。
所得结果可以预测某种药物潜在的癌症治疗作用。对于这种技术,选择GI50值小于10μg/ml的化合物用于进一步的研究。GI50数据不仅可预测某种药物是否为细胞生长抑制剂,而且可以预测它是否具有潜在减小肿瘤的作用。

毒性数据
毒性通过以下文献报道的方法评价:Toxicology in Vitro,15(2001)571-577,J.Luber Narod等:“Evaluation of the use of in vitromethodologies as tools for screening new compounds for potential in vivotoxicity”。
方法
为了评价各种药物对正常细胞的细胞毒性,使用96孔板,在板上以5000细胞/孔的密度接种(除了FDC-P1以外,它以12,000细胞/孔接种)正常细胞系(ATCC,表1),所述细胞系按照ATCC的指导维持:AML-12,正常小鼠肝细胞;NRK-52E,正常大鼠肾细胞;L8,正常大鼠骨胳肌细胞;FDC-P1,正常小鼠骨髓干细胞;H9c2(2-1),正常大鼠心肌细胞。加入受试药物前让各板中细胞静置过夜。此外,原生神经元培养物用胚胎(第e-17天)的完整脑(前脑和脑干)和脊髓按照既有方法(Federoff and Richardson,1997)制备。
以不同浓度(1×10-10-0.01mg/ml终浓度)向每个孔(100μl培养基)中加入10μl溶于培养基的药物,在37℃、5%CO2下进一步温育过夜。在24h后进行检测。所有实验重复至少三次,并且以一式二份检测。
1.MTS检测(CellTiter 96AQueous)根据制造商(Promega)的说明书(针对所有细胞类型)进行。细胞存活力(线粒体活性)通过甲底物的酶法转化确定。

体外评价化合物的ADME-TOX特征
分配系数(log D)
化合物的分配系数提供其亲水亲油平衡的热力学度量。亲油性是一种影响化合物的药动学和药效学特性的主要结构因素。在水或缓冲液与1-辛醇间的分配系数是最广泛运用的化合物亲油性的量度。
分配系数的测量是基于微型化摇瓶法进行评价。缓冲液(Dulbecco氏PBS,pH7.40)用作水相。将受试化合物以100μM的浓度溶于DMSO。在辛醇-缓冲液分配后的最终DMSO浓度(1%)非常底以避免分配偏差。在相平衡60分钟后,缓冲相中化合物含量用光电二极管阵列检测器通过HPLC检测。从总的化合物含量减去缓冲液中化合物含量得到辛醇相中化合物含量,总的化合物含量用校正样品确定。
Log D计算为辛醇相中化合物含量除以缓冲相中化合物含量后的Log10。log D微测定的有效范围为约-0.5至+4.5。
体外肠吸收检测
肠上皮渗透性是确定候选药物在人的吸收速率和程度以及最终生物利用度的重要指标。Caco-2渗透性测定可快速判断膜渗透性,由此帮助进行化合物的吸收潜能排序。
Caco-2细胞系为在培养物中分化并且类似人小肠上皮内衬的人结肠腺癌细胞系。它已经被广泛用作新化合物的药物运输和渗透性筛选的体外肠上皮模型。
在顶端至基底外侧(A至B)方向穿过细胞单层(Caco-2的TC-7亚克隆)检测表观渗透系数(Papp),所述细胞单层在聚碳酸酯滤膜上培养。测试50μM的化合物,最终DMSO浓度为1%。样品通过HPLC-MS或HPLC-MS/MS分析。
将受试化合物加入顶端侧,在温育2小时后,根据受试化合物在基底外侧出现的速率确定Papp。在每个检测中测试作为对照的两种化合物心得安(高渗透性)和雷尼替丁(渗透性差)。此检测结果可以用于化合物的吸收潜能排序。Papp等于或大于20×10-6cm/s的化合物被认为是可能具有高渗透性并且很可能“没有渗透性限制”。Papp小于5×10-6cm/s的化合物被认为渗透性很差并且很可能“渗透性有限”。Papp大于5×10-6但小于20×10-6cm/s的化合物被认为具有中等渗透性。
新陈代谢
肝代谢是药动学特性的主要决定因素,快速第一遍代谢是低生物利用度的主要原因。汇集的肝微粒体和重组物细胞色素P450′s用于代谢评价新发现化合物、前导化合物和新药用化合物。代谢筛选研究结果用于以下目的:
●检测化合物产生代谢的最初速率
●调查药物代谢的主要途径
●预测体内药动学特性
●研究药物-药物相互作用的可能性
用包括微粒体酶和胞质酶活性的人肝S9匀浆确定代谢稳定性。受试化合物以1μM浓度稀释于甲醇(0.625%)和乙腈(0.625%),在人肝汇集物(蛋白质=1mg/mL)中于37℃温育60分钟。通过HPLC-MS/MS确定对应于所有被分析物(代谢产物)的峰面积。记录峰面积,确定被分析物峰面积与各被分析物内标的峰面积的比。前体化合物在60分钟后保留量与在时间为0时的保留量的比(百分数表示)报告为代谢稳定性。值越高说明代谢稳定性越高。
抑制细胞色素P450(CYP450)
细胞色素P450是一组主要位于肝的相关酶,参与药物的代谢。药物对这些CYP的抑制作用与药物-药物相互作用和毒性有关。
CYP3A4是成人中发现的CYP3A酶的最常见形式,并且是涉及大多数药物作用的形式。CYP2D6使超过25%的临床用药代谢。
对于CYP2D6抑制作用检测,一式两份测试10μM的化合物,其中甲醇和乙腈的终浓度为0.25%,并且存在浓度为1.5μM的萤光底物AMMC(3-[2-N,N-二乙基-N-甲基铵]乙基)-7-甲氧基-4-甲基香豆素)。用酶在37℃温育450分钟后,分光荧光法检测AMMC在AHMC(3-[2-N,N-二乙基-N-甲基铵]乙基)-7-羟基-4-甲基香豆素)中的转化。
对于CYP3A4抑制检测,一式两份测试10μM的化合物,其中甲醇和乙腈的终浓度为0.25%,并且存在萤光底物BFC(50μM)。用酶在37℃温育30分钟后,分光荧光法检测BFC(7-苄氧基-4-三氟甲基香豆素)在HFC(7-羟基-4-三氟甲基香豆素)中的转化。
对于这两种检测,从合适温育时间后检测的荧光强度减去在t=0检测的荧光强度。通过对比包含受试化合物的温育物的荧光性与包含相同溶剂溶媒的对照样品的荧光性计算信噪比。计算对照活性的百分数,报告为抑制百分数。
体外安全评价.细胞存活力
用原生人肝细胞(HEPG2)体外研究化合物的毒性潜能。一式两份测试30μM的化合物,其中最终DMSO浓度为1%。在37℃温育24h后,通过将氧化性alarmarBlue(刃天青)转化为还原性alarmarBlue(试卤灵)检测细胞存活力。氯丙嗪用作对照化合物。结果表达为对照值的抑制百分数。
