通过L.Castedo等在《合成通讯》(Synlett)2001,7,1164中所述、通过基于硝酮与炔的1,3-偶极环加成的新途径得到层状素I和K(1)。关键的环加成得到异噁唑啉,其重排而得到中心吡咯环。
F.Albericio等在《有机通讯》(Org.Lett)2003,5,2959中描述了层状素U和L的总固相合成。
Ishibashi F.等在《天然产物杂志》(J.Nat.Prod.),2002,65,500-504中描述了某些层状素衍生物的合成和结构活性相关性。
抗癌药的主要靶的发现是更好地理解其作用机制和指导临床上有用的类似物研发的关键因素。为了解释这种情况,可以参照喜树碱(CPT),它在20世纪60年代早期被发现,但是仅成功研发就在四分之一个世纪之后,当时鉴定了其主要且可能是唯一的分子靶:拓扑异构酶I时。CPT使DNA-拓扑异构酶I复合物稳定这一在1985年中的观察结果为安全的CPT类似物的理性研发提供了起点,其研发在20世纪90年代中期达到顶点,且批准了托泊替康和伊立替康用于治疗卵巢癌和直肠癌。
在过去的10年中,对非-CPT拓扑异构酶I毒物的探索极为活跃,但仅发现了有限数量的可能的拓扑异构酶I毒物。
发明概述
我们已经发现了层状素代表着新的和有前途的系列拓扑异构酶I抑制剂。该药物刺激拓扑异构酶I-介导的DNA剪切的能力与其潜在的细胞毒性之间的相关性使得它们用作抗癌药。
本发明涉及通式III的化合物或其药物上可接受的盐、衍生物、前体药物或立体异构体:

优选R1-R8和R′2-R′6中的至少一个不为H、OH、OCH3、SO3Na,最优选至少两个不为H、OH、OCH3、SO3Na。还优选这些取代基中的至少一个含有至少2个、更优选至少3个、更优选至少4个碳原子3。我们特别优选R′4和R7,且还可能的是R1,含有这些最少的碳原子数。
这些化合物的抗肿瘤活性包括白血病、肺癌、结肠癌、肾癌、前列腺癌、胰腺癌、宫颈癌、卵巢癌、乳腺癌、肉瘤和黑素瘤。
本发明在另一个方面中涉及用作抗癌药的药物组合物,其含有本发明的化合物或其药物上可接受的盐、衍生物、前体药物或立体异构体作为活性组分和药物上可接受的载体。
本发明还涉及上述通式III或其药物上可接受的盐、衍生物、前体药物或立体异构体在治疗癌症或在制备用于治疗癌症的药物中的应用。
本发明在另一个方面中还涉及上述通式III或其药物上可接受的盐、衍生物、前体药物或立体异构体作为拓扑异构酶I抑制剂的应用。
发明详述
为发现抗癌药而在靶向拓扑异构酶I上的15年努力已经导致鉴定了能够使DNA-拓扑异构酶I共价复合物稳定的几个家族的化合物。领先的系列毫无疑问是喜树碱家族,其具有两种被批准用于癌症治疗的药物托泊替康和伊立替康和几种目前处于临床试验中的第二代(例如勒托替康,依沙替康)和第三代(例如diflomotecan)喜树碱类似物。然而,除喜树碱外,仅几种拓扑异构酶I毒物已经达到I期临床试验。已经报导了使用糖基吲哚并卡唑类有前景的结果,但迄今为止在高级临床试验中仍然没有非-CPT拓扑异构酶I毒物。对新系列的拓扑异构酶I毒物的需求仍然迫切。
目前我们已经令人意外地发现天然层状素及其类似物为有效的拓扑异构酶I抑制剂且它们表现出不同于为众所周知的拓扑异构酶I抑制剂和化疗剂的喜树碱的序列特异性分布,提示它们可以区分识别拓扑异构酶I-DNA界面。
因此,本发明涉及如上述所定义的通式III的化合物、其作为抗肿瘤药的应用和含有它们的药物组合物。
下面给出了通式III和IV中取代基的指导:

海洋生物碱层状素D(LAM-D,3)最近被表征为人拓扑异构酶I的有效毒物,对肿瘤细胞具有显著细胞毒性活性。我们在本文中报导了LAM-D系列中结构-活性相关性。
将母体生物碱的典型的6H-[1]苯并吡喃并[4′,3′:4,5]吡咯并[2,1-α]异喹啉-6-酮戊环平面生色团的8、14和20位的三个酚OH上引入不同取代基的两组三酯化合物作为拓扑异构酶I抑制剂测试。
引入氨基酸残基的化合物显著促进人拓扑异构酶I断裂DNA。被亮氨酸、缬氨酸、脯氨酸、苯丙氨酸或丙氨酸残基,或相关氨基酸侧链三取代的LAM-D衍生物使拓扑异构酶I-DNA复合物稳定。检测这些分子的DNA断裂位点T↓G或C↓G二核苷酸与LAM-D(3)的相同,但稍不同于喜树碱观察到的,喜树碱仅TIG处刺激拓扑异构酶I-介导的断裂。
在前列腺(DU-145和LN-CaP)、卵巢(耐ecteinascidin-743的IGROV和IGROV-ET)和结肠(耐阿霉素的LoVo和LoVo-Dox细胞)癌细胞(但非HT29结肠癌细胞)的情况下,最细胞毒性化合物对应于最有效的拓扑异构酶I毒物。观察到的细胞毒性与拓扑异构酶I抑制之间的相关性强烈提示可以将拓扑异构酶I-介导的DNA断裂测试用作研发该系列优秀的类似物的指导。
基于DNA松弛和DNA断裂(Bailly,C.用于研究拓扑异构酶I抑制剂的DNA松弛和断裂试验(DNA relaxation and cleavage assays to study topoisomerase I inhibitors)一《酶学方法》(Methods Enzymol.)2001,340.610-623)的两种试验用于评价层状素类似物对人拓扑异构酶I的催化活性的作用。
在第一种试验中,在没有或有测试化合物存在的情况下,用拓扑异构酶I松弛超螺旋质粒DNA,各测试化合物的浓度为1μM。然后,通过在含有用于染色DNA的溴化乙锭的琼脂糖凝胶上进行凝胶电泳分离DNA松弛产物。用作阳性对照的生物碱喜树碱显著促进通过拓扑异构酶I的DNA断裂。类似地,在有LAM-D(3)存在的情况下,对应于带切口DNA的泳带的强度显著得到增强,表明这种天然产物也使DNA-拓扑异构酶I共价复合物稳定。这种功能检测用于在合成的各种类似物中鉴定拓扑异构酶I毒物(poison)。带有5-6个饱和键(11、22、108、109、139)的类似化合物在本检测中无活性。
将不同的阳离子基团,大部分是氨基酸残基,引入LAM-D的三个苯氧基位。使用带正电荷的分子40(Ala)、39(Leu)、36(Val)、33(Pro)和25(Phe)观察到了拓扑异构酶I的显著抑制,而使用相应的NH-Boc衍生物或非平面的(non-planar)C5-C6类似物没有观察到这种现象。Phe衍生物的功效显著低于其它的均或多或少等效地抑制拓扑异构酶I的氨基酸衍生物。使用Val衍生物研究立体特异性,为此,我们比较了(L)(36、38、135、144)和(D)(17、32、34、122)异构体的活性,但这两个系列之间没有差异。化合物17和36均刺激提高所述酶的DNA断裂。使用C5-C6双链(38、122)或C5-C6单链(32、34、135、144)系列中的Boc-保护的类似物没有观察到该作用。还发现氨基化合物24和169抑制拓扑异构酶I。
使用鉴定的各阳性化合物进行浓度依赖性测定并作了比较LAM-D(3)与三种类似物Val(D)(17)、Pro(33)和氨基化合物169的抗-拓扑异构酶I活性的一些有代表性的凝胶。后一种化合物与(3)在刺激通过拓扑异构酶I的DNA断裂方面等效。在所有情况中,剂量反应分析证实阳离子LAM-D类似物有效抑制所述酶。
显然,在LAM-D(3)的8、14和20位的酚OH上导入氨基酸官能基对拓扑异构酶I抑制没有不利作用。当将Leu、Val、Ala或Pro残基引入LAM-D骨架上时,完全维持了拓扑异构酶I-介导的DNA断裂的程度,而不带电荷的基团则消除了抗-拓扑异构酶I活性。例如,苯丙氨酸残基的有利作用远低于脯氨酸或丙氨酸残基。引入阳离子基团促进拓扑异构酶I抑制这一观察结果提示药物结合DNA的能力的提高可以导致更好的酶抑制。
基于通过拓扑异构酶I的断裂放射性标记的DNA底物的第二种试验用于证实阳离子层状素衍生物确实有效地起拓扑异构酶I毒物的作用。在有不同化合物存在的情况下,使仅在3′端上末端标记的117-bp DNA限制片段进行拓扑异构酶I断裂,并用测序型聚丙烯酰胺凝胶分离DNA断裂产物。该测试的优点在于检测断裂位点并通过核苷酸分离使其定位,由此提供有关断裂的位点选择性的信息。
参比药物CPT在核苷酸位点26、48和81上产生三个位点,所有三个位置均相当于T↓G位。认为在有CPT存在下TG位点上的断裂是因拓扑异构酶I与T残基的相互作用以及CPT分子与相邻G残基的堆积所致。可以在凝胶上部检测到第四个弱位点(T↓G107)。
序列选择性分布(sequence selectivity profile)稍不同于层状素类似物。LAM-D在T↓G48和T↓G81位点上的拓扑异构酶I-介导的DNA断裂方面的有效性低于CPT,但它诱导C↓G73上的另一个断裂位点。这能够反映出与拓扑异构酶I-DNA共价复合物相互作用的不同方式。
使用诸如39(Leu)、36(Val)、33(Pro)和25(Phe)的阳离子衍生物获得了与3相同的断裂分布(profile),而使用相应的NH-Boc衍生物或非平面C5-C6类似物没有获得这类结果。还发现氨基化合物169和7刺激通过所述酶的DNA断裂且在此,我们还发现(L)(36)与(D)(17)Val异构体之间没有差异。因此,这些结果与通过松弛检测获得的那些结果完全一致且由此验证了阳离子层状素衍生物有效抑制拓扑异构酶I的结论。
