Abstract
公开了具有一个带有式(VIa或VIb)结构的1,4桥稠合的海鞘素五环体系的化合物以及其中的1,4桥上的-NH2或-OH为衍化的化合物。此种化合物在肿瘤治疗方面是有用的。
Description
本发明涉及抗肿瘤海鞘素衍生物。
发明背景
海鞘素是从海洋被囊动物Ecteinascidia turbinata中分离的非常有效的抗肿瘤剂。一些海鞘素先前已在专利和科学文献中有报道。
美国专利号5256663描述包含提自热带海洋无脊椎动物Ecteinascidia turbinata的物质(在此称为海鞘素)的药用组合物,及此类药用组合物作为哺乳动物抗菌、抗病毒和/或抗肿瘤剂的用途。
美国专利号5089273描述提自热带海洋无脊椎动物Ecteinascidiaturbmata的物质(在此称为海鞘素729,743,745,759A,759B和770)的新的药用组合物。这些化合物可用作哺乳动物抗菌和/或抗肿瘤剂。
美国专利号5478932描述从加勒比海被囊动物Ecteinascidiaturbinata分离的海鞘素,所述物质体内实验证明可抑制P388淋巴瘤、B16黑素瘤、M5076卵巢瘤、lewis肺癌以及LX-1人肺和MX-1人乳腺异种移植肿瘤。
美国专利号5654426描述从加勒比海被囊动物Ecteinascidiaturbinata分离的几种海鞘素,所述物质体内实验证明可抑制P388淋巴瘤、B16黑素瘤、M5076卵巢瘤、lewis肺癌、及LX-1人肺和MX-1人乳腺异种移植肿瘤。

其中:
R1是酰氨基亚甲基基团如-CH2-NH-CO-CR25aR25bR25c,其中R25a 和R25b形成酮基或者一个是-OH、-NH2或-OCOCH3而另一个是-CH2COCH3、-H、-OH或-OCOCH3,条件是当R25a是-OH或-NH2时,则R25b不是-OH,及R25c是-H、-CH3或-CH2CH3,或者R1是酰氧基亚甲基基团如-CH2-O-CO-R,其中R是-C(CH3)=CH-CH3或-CH3;

其中,由R1、R2、R3、R4、R5、R6、R7、R8、R9、R10定义的取代基基团分别独立选自H、OH、OCH3、CN、=O、CH3;其中X是在包含在所述天然产物中的不同酰胺或酯官能团。其中每个点划线的环表示一个、两个或三个任选双键。
因此,根据本发明,我们提供新的和已知的化合物生产的半合成路径。本发明的半合成路径各自包括一些转化的步骤以达到所需的产物。各步骤本身即是按照本发明的方法。本发明不限于所举例的路径,在适宜时,例如通过改变转化步骤的顺序,可以提供其他的路径。
本发明特别涉及提供通式(XVI)的21-氰基起始原料:
其中R1、R5、R8、R14a、R14b、R15和R18如本文所定义。
其他在21位带有不同取代基的式(XVI)化合物也可作为可能的起始原料。一般来说,其中R21是羟基的能够经式(XV)化合物的21-羟基的亲核取代产生的任何衍生物为候选的化合物。合适的21-取代基的实例包括但不限于:
巯基基团;
烷硫基基团(具有1到6个碳原子的烷基基团);
芳硫基基团(具有6到10个碳原子并且是不取代或由1到5个取代基取代的芳基基团,所述取代基选自例如具有1到6个碳原子的烷基基团、具有1到6个碳原子的烷氧基基团、卤原子、巯基基团及硝基基团);
氨基基团;
单或二烷基氨基(所述烷基或每个烷基基团具有1到6个碳原子);
单或二芳基氨基基团(所述或每个芳基基团如上述涉及芳硫基基团的定义);
式-C(Ra)(Rb)-C(=O)Rc的a-羰基烷基基团,其中
Ra和Rb是选自氢原子、具有从1到20个碳原子的烷基基团、芳基基团(如上述涉及芳硫基基团的定义)和芳烷基基团(其中具有1到4个碳原子的烷基基团由如上述涉及芳硫基基团的定义的芳基基团取代),前提是Ra和Rb之一是氢原子;
Rc选自氢原子、具有从1到20个碳原子的烷基基团、芳基基团(如上述涉及芳硫基基团的定义)、芳烷基基团(其中具有1到4个碳原子的烷基基团由如上述涉及芳硫基基团的定义的芳基基团取代)、具有1到6个碳原子的烷氧基基团、氨基基团或者如上定义的单或二烷基氨基基团;
这样,在更常规的方面,本发明涉及第一步是用一种亲核试剂生成21-衍生物的方法。我们把这种化合物称作21-Nuc化合物。优选的起始原料21-Nuc化合物具有式(XIV)的结构:
其中,至少一个环A或E是醌醇(quinolic)环。
因此,除了利用21-氰基化合物外,也设计了使用其他含有亲核基(nucleophile)的化合物生产式(XVI)的类似化合物的方法,其中21-位由另一亲核基团,21-Nuc基团保护。例如,在21-位具有烷基氨基取代基的式(XVI)21-Nuc化合物可以通过其中R21是羟基的式(XV)化 合物与适当的烷基胺反应制得。在21-位具有烷硫基取代的式(XVI)21-Nuc化合物也可以通过其中R21是羟基基团的式(XV)化合物与适当的烷基硫醇反应制得。作为选择,在21-位具有a-羰基烷基取代基的式(XVI)21-Nuc化合物可以通过其中R21是羟基基团的式(XV)化合物与适当的羰基化合物,通常在碱存在下反应制得。对于其它的21-Nuc化合物,也可以采用其它可以利用的路径。
21-氰基的存在对于一些终产物是必需的,尤其是海鞘素770和phthalascidin,而对于其他终产物,由于它易于转化成另一取代基如21-羟基而起着保护基的作用。使用21-氰基化合物作为起始原料有效地稳定了随后发生的合成各步骤期间产生的分子,直至它任选被除去。其他21-Nuc化合物可以提供此种益处和其他益处。
优选的起始原料包括式(XV)或(XVI)化合物,其中R14a和R14b 均为氢。优选的起始原料也包括式(XV)或(XVI)化合物,其中R15为氢。进一步优选的起始原料包括式(XV)或(XVI)化合物,其中环E是一个酚环。优选的起始原料还包括式(XV)和(XVI)化合物,其中至少R5、R8、R15和R18中的一个,最好至少两个或三个不为氢。
本发明合适起始原料的实施例包括番红霉素A、番红霉素B、番红霉素C、番红霉素G、番红霉素H、番红霉素S、番红霉素Y3、番红霉素Yd1、番红霉素Ad1、番红霉素Yd2、番红霉素AH2、番红霉素AH2Ac、番红霉素AH1、番红霉素AH1Ac、番红霉素AR3、矶海绵霉素A、矶海绵霉素B、矶海绵霉素C、矶海绵霉素D、矶海绵霉素E、矶海绵霉素F、锉海绵霉素、番红霉素D、番红霉素F、番红霉素Mx-1、番红霉素Mx-2、番红菌素A、番红菌素B和番红霉素R。对于基团R21,优选起始原料在21位置具有氰基。
在一个特别优选的方面,本发明包括一个半合成方法,其中对番红菌素B使用转化的步骤:
番红菌素(safracin)B
番红菌素B有一个与海鞘素密切相关的环系。该化合物具有相同的五环结构及在右旋芳香环,环E上具有相同的取代形式。
本发明更优选的起始原料具有21-氰基基团。目前本发明最优选的化合物是式2化合物。该化合物直接得自番红菌素B并被认为是半合成方法中的关键中间产物。
化合物2
使产生番红菌素B的荧光假单胞菌菌株发酵,并用氰化物离子处理液体培养基,得到氰基番红菌素B。优选的荧光假单胞菌菌株是A2-2菌株,FERM BP-14,在EP-A-055299的方法中使用了该菌株。氰化物离子的合适来源是氰化钾。在通常处理中,过滤所述液体培养物并加入过量氰化物离子。在搅拌适当时间,如搅拌1小时后,pH呈碱性,如pH 9.5,接着从有机提取物得到粗提物,可将其进一步纯化得到氰基番红菌素B。
通常,由21-氰基起始化合物转化成本发明产物包括:
a)如果需要,将环E的醌体系转化成酚体系;
b)如果需要,将环A的醌体系转化成酚体系;
c)将环A的酚体系转化成亚甲基二氧基苯酚环;
d)经环B的1-位和4-位生成式(IV)、(VI)或(VII)的桥接螺环系;及
e)适当时衍生化,如酰化。
步骤(a),如果需要,环E的醌体系转化成酚体系可以通过常规的还原方法实现。尽管可以使用其他的还原体系,合适的试剂体系是氢与钯-碳催化剂。
步骤(b),如果需要,类似于步骤(a),将环A的醌体系转化成酚体系,不需要更详细叙述。
步骤(c),环A的酚体系转化成亚甲基二氧基苯酚环可以通过几种方法实现,很可能包括步骤(b)。例如,醌环A可以在7-位的甲氧基取代基上经脱甲基并还原成二氢醌,接着用合适的亲电试剂诸如CH2Br2、BrCH2Cl,或类似的二价试剂捕捉直接生成亚甲基二氧基环系;或者使用诸如可以生成取代的亚甲基二氧基环系的硫代羰基二咪唑的二价试剂捕捉,可以转化成所希望的环。
步骤(d)典型地通过用可帮助生成所需桥键的桥键形成剂在1-位适当取代来实现,在4-位形成一个exendo醌的甲基化物,并使该甲基化物与1-取代基反应得到桥结构。优选的桥键形成剂是式(XIX)化合物
其中,Fu表示保护官能基团,诸如基团-NHProt4a或OProt4b,Prot3 是保护基,以及虚线显示任选的双键。
合适地,通过首先在环A和B的结合部位10-位引入羟基,生成所述甲基化物,得到式(XX)的部分结构:
或较优选式(XXI)的部分结构:
其中,基团R”是为所需的式(IV)、(V)、(VI)或(VII)的基团进行选择的。对于前两个此类基团,基团R”一般取-CHFu-CH2-SProt3的形式。接着所述保护基可以除去并适当地加以修饰得到所需的化合物。
在通过引用结合到本文中的美国专利号5721362中提供了用于步骤(d)的典型方法。具体的参考见所述美国专利中的栏目8、步骤(1)及实施例33及相关内容。
在步骤(e)中的衍生化可以包括例如使用Ra-CO-基团的酰化,以及12-NCH3基团生成12-NH或12-NCH2CH3的转化。此种转化可以通过使用已有方法在其他步骤之前或其后实现。
通过例证的方法可以转化成中间体25;
以及由此衍生物有可能引进许多可以转变成本发明化合物的半胱氨酸衍生物。优选的半胱氨酸衍生物是以下述两个化合物作为例子:
本发明的一种方法是经一系列反应将氰基番红菌素B转化成中间体Int-25,所述的系列反应主要包括(1)去除位于环A上的甲氧基,(2)还原环A及经一罐法(one pot)生成亚甲基二氧基,(3)氢解位于碳1的酰胺基官能团,(4)将所得的氨基基团转化为羟基,见表V。
所述方法直接使用半胱氨酸残基Int-29生成中间体Int-27,避免在化合物Int-25的环B位置1的伯醇官能团的保护和脱保护。为了具有与已存在的烯丙基和MOM基团相容的能力,用β-β-β-三氯乙氧基羰基保护基团在半胱氨酸衍生物Int-29的氨基上进行保护。中间体Int-27被直接氧化及环化。这些情况与在合成的后面阶段使用的不同脱保护策略一起形成新的路径,并且该路径比US 5721362中的方法更易于修改以适于工业化生产。
2-氰基化合物转化成中间体Int-25通常包括下述步骤(见流程图V):
通过使Int-2与叔丁氧羰基酸酐反应生成式Int-14保护的化合物;
通过在乙腈中的溴甲基甲基醚与二异丙基乙胺反应将Int-14转变为式Int-15的二-保护的化合物;
通过与氢氧化钠的甲醇溶液反应选择性地消除Int-15中醌系统的甲氧基,得到式Int-16化合物;
接着通过使用下面的优选程序Int-16转化为式Int-18的亚甲基-二氧基化合物:(1)用10%Pd/C在氢气压下还原Int-16化合物的醌基;(2)通过与溴代氯甲烷和碳酸铯在氢气压下反应使氢醌中间体转化成式Int-17的亚甲基二氧基化合物;(3)通过将自由羟基保护为OCH2R基团,使Int-17转变成式Int-18化合物。此反应使用BrCH2R和碳酸铯进行,其中R可以是芳基、CH=CH2、OR’等。
通过与HCl的二氧六环的溶液反应消除Int-18的叔丁氧基羰基和甲氧基甲基保护基得到式Int-19化合物。该反应通过混合Int-18与三氟乙酸在二氯甲烷中的溶液也可以完成。
通过Int-19与异硫氰酸苯基酯反应生成式Int-20的硫尿化合物;
通过与氯化氢的二噁烷溶液反应,将式Int-20化合物转化为式Int-21的胺化合物。
通过与氯甲酸三氯乙酯和吡啶反应,将式Int-21化合物转变为 Int-22的N-Troc衍生物;
通过Int-22与溴甲基甲基醚和二异丙基乙胺反应生成式Int-23的保护的羟基化合物;
通过与乙酸和锌反应,将式Int-23化合物转变为Int-24的N-H衍生物;
通过与在乙酸中的亚硝酸钠反应,将式Int-24化合物转变为式Int-25的羟基化合物。或者,可以使用在乙酸和乙腈混合物中的氮的四氧化物接着用氢氧化钠处理。也可以在乙酸酐-乙酸混合物中使用亚硝酸钠,然后用氢氧化钠处理。
如流程VI所示进行可以由中间体Int-25转化成本发明的最终中间体化合物Int-35或Int-36:
流程VI
通过用(S)-N-2,2,2-三氯乙氧羰基-S-(9H-芴-9基甲基)半胱氨酸Int-29保护伯羟基官能团,将式Int-24化合物转变为衍生物Int-30;
经用氢化三丁基锡和二氯化钯-双(三苯基膦)清除烯丙基,将式Int-30的保护的化合物转化为酚衍生物Int-31;
经用苯亚硒酸酸酐在低温下氧化,将式Int-31的酚化合物转变为式Int-32化合物;
通过下述顺序,将式Int-32的羟基化合物转变为内酯Int-33:(1)使式Int-32化合物与2eq.的三氟甲磺酸(triflic)酐和5eq.DMSO反应。(2)接着与8eq二异丙基乙胺反应。(3)然后与4eq.叔丁基醇反应。(4)接着与7eq.2-叔-丁基-1,1,3,3-四甲基胍反应。(5)然后与10eq.乙酸酐反应;
通过用TMSI除去MOM保护基,将Int-33的内酯化合物转变为羟基化合物Int-34;
通过与Zn/AcOH反应消除式Int-34化合物的N-三氯乙氧羰基基团生成化合物Int-35;
经与N-甲基吡啶鎓甲醛(carboxaldehyde)氯化物反应,然后与DBU反应将氨基化合物Int-35转变为相应的a-酮基内酯化合物式Int-36;
以类似的方法并使用与用于半胱氨酸衍生物Int-29的相同试剂,但(f)和(g)转化除外,可以使用半胱氨酸衍生物Int-37进行中间体化合物Int-25向ET-743的转化。所述反应顺序可以下述流程VII举例说明:
