Abstract
本发明涉及由下列通式I代表的新型类维生素A衍生化合物或其可药用盐,其中X、R1、R2和R3如本文所定义。此外,本发明涉及通式I化合物的生产方法并涉及包括通式I化合物的抗癌组合物。本发明的通式I化合物发挥高度的抗癌作用而不会产生不良副作用。
Description
技术领域
本发明涉及具有抗癌活性的新型类维生素A衍生物或其可药用盐、所述化合物的生产方法和包括所述化合物作为活性组分的抗癌药物组合物。
背景技术
已经开发了许多用于预防和治疗癌症的特定化学物质。这类抗癌物质的代表性实例包括维生素A(视黄醇)和类维生素A。美国专利US4,310,546中公开了N-(4-酰氧基苯基)-全反式-视黄酰胺(retinamide),美国专利US4,323,581中公开了N-(4-羟基苯基)-全反式-视黄酰胺,且美国专利US4,665,098中公开了称作fenretimide的N-(4-羟基苯基)视黄酰胺。
类维生素A通过与存在于细胞核中的RAR(视黄酸受体)或RXR(类维生素A的X受体)结合以有助于RAR/RXR的转录活性而与细胞分化和个体发育有关。已知这些化合物通过与转录激活物AP-1(激活蛋白-1)间接发生相互作用并抑制AP-1活性以防止涉及癌症发展和转移的AP-1的靶基因表达而发挥出抗癌作用(Yang-Yen H.F.等《新生物学》(New Biol.)3:1206-1219,1991)。另外已知视黄醇类和类维生素A抑制细胞过度增殖并诱导分化或编程性细胞死亡且由此可能用于预防和治疗癌症(Hong W.K.和Itri L.M.,《生物化学与药物》(Biol.Chem.Med.)第2版,Sporn等编辑,New York:Raven Press;597-630,1994)。然而,类维生素A的治疗用途受到限制,因为这些化合物伴随有由类维生素A与其受体结合而活化的某些蛋白质引起的不良副作用,例如皮肤刺激、对器官的毒性和器官畸形(Hathcock J.N.等《美国临床营养学杂志》(Am.J.Clin.Nutr.)52,183-202,1990)。
此外,美国专利US6,274,742中公开了由下列通式代表的N-高半胱氨酸硫代内酯视黄酰胺化合物:
经证实上述化合物中的某些具有相当好的抗癌作用和低副作用且处于临床试验中。这类有代表性的实例包括N-(4-羟基苯基)-全反式-视黄酰胺化合物。然而,甚至N-(4-羟基苯基)-全反式-视黄酰胺化合物也不能满足对于抗癌药物的要求,即这些化合物在以高剂量口服给药时对组织有刺激作用,这是类维生素A族药物的一个固有难题。
本发明的公开内容
因此,本发明的一个目的是提供在结构上不同于迄今为止已知的类维生素A化合物且比它们发挥出提高的抗癌作用而不良副作用减少的新型类维生素A衍生物。

可以通过常规途径给予本发明的视黄酰胺衍生物,所述的常规途径例如有以片剂、胶囊剂、包糖衣丸或包薄膜衣片、溶液或混悬剂形式口服给药;以栓剂形式经直肠给药;和例如以肌内方式或通过静脉内和/或鞘内和/或脊柱内注射或输注的非肠道给药。

使用3-(4,5-二-甲基噻唑-2-基)-2,5-二-苯基四唑溴化物(MTT,Sigma)试验以剂量依赖性方式检测受试化合物对各种癌细胞增殖的作用。在MTT试验中,用不同浓度的测试化合物处理结肠、肝、宫颈、卵巢和乳腺的癌细胞系。存活的癌细胞将MTT还原成可以通过吸光度测定的深蓝色MTT甲。
将按照本发明制备的新型类维生素A衍生化合物用作测试化合物,同时将N-视黄基-4-氨基苯酚(HPR)和全反式视黄酸(ATRA)用作对照。以3000个细胞/孔的初始密度将结肠癌细胞HCT116、DLD-1和HT29、宫颈癌细胞HeLa和CaSki、卵巢癌细胞SKOV-3、2774和OVCAR-3、肝癌细胞SK-Hep-1、PLCPRF5和HepG2以及乳腺癌细胞ZR75-1和MDA-MB 231接种在96孔板中。在细胞贴附于孔壁后,用不同浓度(0.5μM、1μM、2.5μM、5μM、10μM)的新制类维生素A将培养基处理48小时。将50μl的MTT溶液(2mg/ml的PBS溶液)加入到细胞培养基中。在37℃和5%CO2气氛下将该反应混合物温育4小时。除去上清液并加入150μl的DMSO。用分光光度法在550nm处测定光密度。附图1显示用本发明类维生素A衍生物KCBG8、9、10、11或41和对照化合物HPR处理的细胞培养基的吸光度。对于本发明的其它类维生素A衍生物,通过该步骤测定吸光度并测定50%生长抑制所需的浓度即IC50值。结果如下面的表1和表2中所示。

正如表中所示,所有的类维生素A衍生物在肝癌HepG细胞中均未表现出抗癌活性。在其它细胞中,ATRA表现出极低的抗癌活性,而目前已知具有最高活性的HPR的IC50为3-20μM,KCBG10具有的IC50为0.5-12μM且KCBG41具有的IC50为0.8-5.5μM。这些衍生物对不同细胞表现出的活性存在差异。特别显示了KCBG10对诸如宫颈癌、卵巢癌和乳腺癌这样的妇女癌症更为有效,而KCBG41对结肠癌和肝癌更为有效。从这些结果中可以注意到类维生素A衍生物KCBG10和KCBG41对癌细胞的抗增殖作用明显优于HPR和ATRA,但在细胞与细胞之间存在差异。
实验例2
将结肠癌HCT116细胞和乳腺癌MCF-7细胞均用5μM类维生素A衍生物KCBG10和KCBG41处理48小时并用光学显微镜(×200)照相。作为对照化合物,使用相同浓度的HPR。结果如附图2中所示。在附图2中,对照代表未处理的细胞。
从结果中可以看出,用本发明KCBG10和KCBG41处理的细胞系比常规的抗癌化合物HPR处理的细胞系在存活癌细胞数量上显著减少。此外,根据死亡细胞的形态判断,认为细胞数量减少是由于编程性细胞死亡所导致的。此外,与实施例1中检测的对癌细胞增殖的作用结果相似,KCBG10对MCF-7细胞的杀伤远大于相同浓度的其它衍生物,KCBG41对HCT116比相同浓度的其它衍生物更为有效。这些结果证实本发明的化合物具有比HPR更优的抗癌作用且对不同类型的癌细胞以不同方式起作用。
实验例3
类维生素A衍生物诱导编程性细胞死亡的作用
为了确定本发明类维生素A衍生物抑制癌细胞增殖的机理,检测受试化合物KCBG10和KCBG41、包括KCBG40作为比较引起的癌细胞的改变。作为对照化合物,使用DMSO和HPR。将KCBG41对之有效的结肠癌HCT116细胞和KCBG10对之有效的乳腺癌MCF-7细胞用于功能差异比较。
3-1)生化DNA断裂试验
在用不同浓度(2.5、5.0、10μM)的各种类维生素A衍生物处理48小时后,将HCT116或MCF-7细胞倾入1mL的PBS并在4℃下以13,000rpm的速率离心1分钟。将所得细胞沉淀重悬于700μl含有17.5μl蛋白酶K(20mg/ml)的裂解缓冲液(500mM Tris,100mM EDTA,0.5%SDS)中并在55℃的水浴上温育3小时。将溶胞产物与700μl苯酚溶液混合,同时缓慢搅拌并以12,000rpm离心5分钟。分离出上清液并再用苯酚提取一次。将上清液与600μl的100%乙醇和60μl的3M NaOAc(pH 7.0)混合并在-20℃下保持2小时。通过以12,000rpm离心10分钟除去上清液而得到沉淀。在用70%乙醇洗涤并干燥后,将DNA沉淀重悬于100μl的TE(Tris-EDTA)缓冲液中并用RNA酶A处理。使获得的样本在1.8%琼脂糖凝胶上在75V下电泳2小时。将回收的DNA用溴化乙锭染色并通过UV灯观察而显示出DNA梯。用0.01%DMSO(表示为附图3中的C)和HPR处理的对照组没有显示出任何DNA梯,而当用本发明的KCBG10和KCBG41处理细胞时,清楚地检测到了因DNA断裂产生的梯形DNA条带(附图3)。此外,与从对细胞增殖的作用观察到的结果相似,低浓度的KCBG10在MGF-7细胞中显示出DNA断裂,而KCBG41以相似浓度在HCT116细胞中显示出DNA片断裂。
3-2)细胞生物学试验
在使用DAPI(4,6-二脒基-2-苯基吲哚)对细胞核中DNA染色的染色试验中观察到了编程性细胞死亡的特征即核浓缩和碎裂。用5μM浓度的HPR、KCBG10、KCBG40和KCBG41处理36小时的HCT116细胞大部分表现出核碎裂(附图4)。在附图4中,对照代表未处理的细胞。通过FACS(荧光激活细胞分选仪)分析来测定结肠癌HTC116细胞和乳腺癌MCF-7细胞中sub-G1 DNA含量以对编程性细胞死亡进行定量(附图5)。最终,为了进一步表征在用类维生素A衍生物处理的细胞中观察到的编程性细胞死亡,通过蛋白质印迹分析与编程性细胞死亡相关的蛋白质、包括PARP(聚(ADP-核糖)聚合酶)和CPP32(天冬氨酸特异性半胱氨酸蛋白酶-3)的裂解情况。5μM浓度的KCBG10和KCBG41诱导所述蛋白质裂解(附图6A)。PARP裂解以时间依赖性方式发生,同时诱导编程性细胞死亡(附图6B)。附图6中的C代表未处理细胞的蛋白质印迹结果。
这些结果提示本发明的类维生素A衍生物通过诱导癌细胞的编程性细胞死亡而具有抑制癌细胞增殖的作用且本发明类维生素A衍生物对癌细胞的这类抗癌细胞增殖作用主要因诱导编程性细胞死亡而导致。
实验例4
类维生素衍生物对类维生素A受体的作用
为了证实本发明类维生素A衍生物对类维生素A受体的作用,用各受体亚族的表达载体和报道基因共转染细胞。作为报道基因,使用氯霉素乙酰转移酶(CAT)基因。按照制造商提供的方案、通过使用SuperFect(QIAGEN)的活化树枝状聚合物法(activated-dendrimermethod)进行转染。将结肠癌细胞以106平板培养于6-孔中。在第2天,将DNA(2μg)和SuperFect试剂的混合物加入到细胞中。在转染过夜后,将培养基与含有不同浓度的类维生素A的新鲜培养基交换24小时并用冷的1×PBS洗涤。收集细胞、将其悬浮于100μl的0.25MTris-HCl(pH 7.6)中并通过3个冻-融循环来进行裂解。在离心(12,000×g,10分钟,4℃)后,回收100μl上清液。按照标准步骤(Sambrook等,1989)对10μl回收的上清液测试其β-半乳糖苷酶活性并通过CAT ELISA(Boeringer Mannheim,Germany)法对50μl回收的上清液测试其报道基因活性。将获得的报道基因活性的数据相对β-半乳糖苷酶活性进行校准以用于比较。用1μM作为测试化合物的类维生素A衍生物KCBG10和KCBG41和作为对照化合物的ATRA和HPR处理细胞并比较CAT酶的表达水平。结果如附图7中所示。
将KCBG10和KCBG41的活性与ATRA(全反式视黄酸)和HPR的活性进行比较。当浓度增加时,在三种RAR亚族中(视黄酸受体:RARα、RARβ、RARγ)KCBG41表现出约50%ATRA和HPR水平的活性。KCBG10在低浓度下没有活性,但随浓度增加表现出活性提高。由于ATRA的显著副作用是由于缺乏对RAR亚族的特异性或对它们的高活性所导致的,所以推定HPR具有相对低的副作用。推测KCBG41具有50%ATRA和HPR水平的副作用,而HPR和KCBG10具有与HPR相似或低于它的副作用。
实验例5
类维生素A衍生物抑制AP-1的作用
为了观察本发明的类维生素A衍生物是否类似于现存的类维生素A而直接抑制AP-1,用各受体亚族的表达载体、AP-1成分c-Jun和报道基因共转染细胞。作为报道基因,使用带有识别胶原酶AP-1位点的CAT酶基因。用1μM作为测试化合物的类维生素A衍生物KCBG10、KCBG40和KCBG41和作为对照化合物的DMS0、HPR和ATRA(视黄酸)处理细胞并比较CAT酶的表达水平。结果如附图8中所示。
本发明的KCBG10和KCBG41对AP-1活性的抑制程度(50%)类似于常规的ATRA和HPR。从这些结果中注意到KCBG10和KCBG41维持了抑制AP-1的作用。
实验例6
类维生素A衍生物抑制癌转移和浸润的作用
之前显示了合成的类维生素A衍生物抑制AP-1的转录活性。此外,众所周知AP-1的主要靶基因MMP(基质金属蛋白酶)涉及癌细胞的转移。因此,通过RT-PCR分析来检测类维生素A衍生物对癌转移的抑制作用。用1μM类维生素A将结肠癌HCT116细胞处理36小时。从该细胞中分离RNA并通过RT-PCR分析MMP-1、-2和-3的mRNA表达水平。就MMP-1和MMP-2而言,HPR和KCBG40对其表达影响极小,KCBG10对其表达影响较弱而KCBG41显著抑制其表达。作为对照,使用GAPDH且证实其表达不受类维生素A影响。同时,MMP-3的表达水平受KCBG40影响较弱、受KCBG41中度影响,而受KCBG10影响显著(附图9)。从这些结果中注意到KCBG10和KCBG41根据MMPs的种类调节其表达。
因此,可能本发明的KCBG10和KCBG41对癌细胞的转移和侵袭的抑制远强于常用的类维生素A。
实验例7
KCBG60对癌细胞增殖的作用
为了证实KCBG60对癌细胞增殖的作用,用不同浓度的KCBG60及其前体、ATRA、4-HPR和丁酸苯酯处理结肠癌细胞和肝癌细胞并用选择性渗透入死亡细胞的锥虫蓝染色。对未被锥虫蓝染色的存活细胞进行计数且结果在表3中表示为相对存活细胞(%)

当用10μM ATRA和丁酸苯酯处理结肠癌HCT116细胞时,对增殖的抑制作用低至10-30%。另一方面,KCBG60在0.5μM浓度下开始抑制增殖且在10μM抑制率达到90%以上。在结肠癌DLD-1细胞和肝癌SK-Hep-1细胞中获得了相似的数据。
从上述结果中发现KCBG60发挥对癌细胞增殖的抑制作用。
实验例8
KCBG60诱导编程性细胞死亡的作用
据推定JCBG60抑制细胞增殖的作用是由于诱导编程性细胞死亡和阻断细胞分裂所导致的。为了确定KCBG60抑制癌细胞增殖的机理,观察KCBG60及其前体导致的形态改变。
用10μM浓度的KCBG60及其前体、ATRA、HPR和丁酸苯酯将细胞处理96小时并用吖啶橙和溴化乙锭双重染色(附图10)。当用0.01%DMSO或丁酸苯酯处理时,细胞保持正常的绿色,这表明大多数细胞存活。与此相比,当用10μM的KCBG60处理时,细胞染上橙色,表明出现编程性细胞死亡,染色试剂透入细胞。因此,KCBG60的抗增殖作用是由于诱导编程性细胞死亡所导致的。
为了定量测定编程性细胞死亡的水平,对用如上所述相同条件处理的细胞进行FACS分析以测定DNA含量(附图11)。在比较具有2N或2N以下DNA含量的死亡细胞的相对比例时,KCBG60处理组和HPR处理组显示出的比例远高于其它组。
同时,已知KCBG60合成过程中的前体HPR诱导编程性细胞死亡。考虑到在用KCBG60处理时细胞聚集成小球形团,所以预计KCBG60诱导编程性细胞死亡。为了再次证实KCBG60诱导的编程性细胞死亡,用DAPI对用KCBG60处理的HCT116细胞进行染色并观察核浓缩的情况,所述核浓缩提示编程性细胞死亡(附图12)。当用0.01%DMSO或丁酸苯酯处理时,观察到细胞核是正常的。与此相比,用KCBG60和已知诱导编程性细胞死亡的类维生素A衍生物处理的细胞显示出小斑点,表明核浓缩。
为了证实上述结果,从如上所述处理的细胞中分离DNA并通过琼脂糖凝胶电泳检测DNA断裂情况(附图13)。用0.01%DMSO或丁酸苯酯处理不诱导染色体DNA的任何断裂。相反,当用KCBG60和ATRA处理细胞时,检测到了由染色体DNA0断裂产生的DNA梯。
从这些结果中注意到本发明的KCBG60通过使癌细胞编程性细胞死亡而抑制增殖。
实验例9
KCBG60对类维生素A受体活性的作用
为了证实本发明KCBG60对类维生素A受体活性的作用,用受体亚族的表达载体和报道基因共转染细胞。作为报道基因,使用带有与相应受体反应的转录控制位点的氯霉素乙酰转移酶(CAT)。用1μM浓度的KCBG60及其前体、ATRA、HPR和丁酸苯酯处理转染的细胞并测定CAT酶的表达水平(表4)。作为RA(视黄酸),将全反式RA(ATRA)用于RAR受体并将9-反式RA用于RXR受体。

已知通过受体依赖性机制起作用的HPR对于全部3种RARs均表现出约50%的ATRA活性。与此相比,KCBG60处理组表现出与对照组和丁酸苯酯处理组一样低的活性。在对RXR型受体转录活性中,获得了相似的结果。
这些结果表明KCBG60不同于常用的类维生素A而几乎对RARs和RXRs没有活性且由此可能与副作用更少相关。
实验例10
KCBG60抑制AP-1活性的作用
为了观察本发明的KCBG60是否类似于现存的类维生素A而直接抑制AP-1,用相应受体亚族的表达载体、AP-1成分c-Jun和报道基因共转染细胞。作为报道基因,使用带有识别胶原酶AP-1位点的CAT酶基因。用1μM的KCBG60及其前体、ATRA、HPR和丁酸苯酯处理细胞并比较CAT酶的表达水平(表5)。

正如表5中所示,KCBG60将AP-1活性抑制到与ATRA或HPR相似的程度(约50%)。与AP-1活性无关的丁酸苯酯正如所预计的没有产生影响。
从这些结果中注意到本发明的KCBG60维持了抑制AP-1的作用。
实验例11
KCBG60对癌转移和侵袭的作用
为了检测本发明的KCBG60是否抑制癌细胞的转移,测定由KCBG60抑制的已知涉及癌细胞转移的MMP(基质金属蛋白酶)的表达水平。用1μM的KCBG60及其前体、ATRA和丁酸苯酯将结肠癌HCT116细胞处理24小时。从该细胞中分离RNA并通过RT-PCR分析MMP-1、-2和-3的mRNA表达水平(附图14)。
RT-PCR分析显示就MMP-1而言,MMPs的mRNA水平减少了约50%,这一结果比ATRA和丁酸苯酯增加了2倍。就MMP-2而言,KCBG60表现出的抑制表达水平比ATRA高两倍。与此相比,丁酸苯酯完全不影响MMP-2的表达。
同时,为了确定KCBG60对HCT116细胞的侵袭潜力的作用,进行体外试验。用1μM浓度KCBG60及其前体、ATRA和丁酸苯酯将结肠癌HCT116细胞处理8小时并转入在表层包被了matrigel(一种人工构建的基底膜)的滤器。在培养预定时间期限后,测定迁移至滤器下侧的细胞数量以确定侵袭程度(附图15)。KCBG60显著(50%)减少了侵袭细胞的数量,超过了ATRA(40%)。丁酸苯酯没有表现出对侵袭的抑制作用。
从上述结果中注意到本发明的KCBG60与其成分相比显著抑制了癌细胞的转移和浸润。
如上所述,本发明所属领域的技术人员会理解可以按照另一种实施方式实施本发明而不会脱离本发明的实质或特征。因此,应理解上述实施例和实验例用于解释目的而不起限定作用。本发明包括由所附权利要求所定义的源于本发明实质和范围的所有改变和修改及其等同技术方案,而不仅仅限于上述对本发明的具体描述。
本发明的类维生素A衍生物通过成分之间的互补作用对癌细胞增殖的抑制作用比其前体更为有效,且由此预计会表现出极佳的抗癌作用。本发明的类维生素A衍生物对所有的类维生素A受体亚型具有相对低的活性但有效抑制AP-1的活性。因此,它们具有低于现存类维生素A类型药物ATRA的副作用且特别是与HPR的副作用相当或低于HPR的副作用。因此,包括本发明类维生素A衍生物作为活性成分的抗癌药可以克服其前体功效差和副作用的难题并表现出优越的抗癌作用,可用于对癌症进行化学预防和治疗。
