相关申请的交叉参考
本申请要求2015年5月11日提交的美国临时申请第62/159,669号的权利,其全部内容通过引入本文而并入。
关于联邦资助研究的声明
本发明是在政府支持下根据由国立卫生研究院颁布的第2P20RR020171号合同做出的。政府享有发明中一定的权利。
发明领域
本发明涉及具有抗肿瘤活性的化合物。具体而言,本发明涉及3-芳基-4H-色烯-4-酮,通常指的是异黄酮,以及该化合物抑制有此需要的患者的癌细胞(例如,前列腺癌)生长的用途。
背景技术
前列腺癌代表着重要的医疗保健负担,是男性癌症相关死亡率的第二大主要原因。参见Siegel,R.;Ma,J.;Zou,Z.;Jemal,A.CA Cancer J.Clin.2014,64,9。这一领域的挑战是在雄激素剥夺治疗(即去势)后复发性前列腺癌的问题。医学去势最初消耗雄性激素,如睾丸激素及其还原形式5α-二氢睾酮。然而,癌症不可避免地复发,一个以前未被认可但又非常危险的后门途径(Fiandalo,M.V.;Wilton,J.;Mohler,J.L.Int.J.Bio.l Sci.2014,10,596)将胆固醇代谢中的中间体17α-氢孕酮首先转化为4-雄甾烯-3,17-二酮,然后转化为二氢睾酮,而不经过睾丸激素。因此,仍然需要开发降低这些雄激素水平的升高的疗法来作为治疗复发性前列腺癌的手段。
发明内容
本发明公开的优点包括3-芳基-4H-色烯-4-酮或其可接受的盐或其药学上可接受的组合物及其用于制备治疗前列腺癌或者用于治疗/抑制复发性前列腺癌药物中的应用。
这些或其他优点至少部分地被具有式(I)的3-芳基-4H-色烯-4-酮或其药学上可接受的盐所满足:
其中Ar是芳基或杂芳基;n为1-5的整数,每个X独立地为卤素或烷氧基,或Ar上多于一个的X一起形成环醚结构;并且其中化合物在C-2位上被H、烷基、环烷基或烷氧基取代,在C-5、C-6、C-7和C-8位独立地被H、羟基(OH)、烷基、环烷基、烷氧基取代,或者C-6和C-7或C-7和C-8上的取代基一起形成取代或未取代的、饱和或不饱和的环状或多环结构,其包括至少一个氧族元素,例如氧或硫。烷基、环烷基、烷氧基和环结构可以是未取代的或取代的。这些取代基包括一个或多个胺基(NR2R3)、羟基、酯,例如乙酰氧基、烷氧基、羰基。
实施方式包括单独的一个或多个以下特征或其组合。例如,本发明的实施方式包括3-芳基-4H-色烯-4-酮,其中Ar是杂芳基,例如吡啶基、二嗪基、嘧啶基、噁唑基或咪唑基。在一些实施方式中,Ar为芳基,例如苯基。在其它实施方式中,3-芳基-4H-色烯-4-酮具有式(II):
在各种实施方式中,3-芳基-4H-色烯-4-酮(II)上的取代基包括:其中C-2取代基为氢H或甲基;在Ar上包括一个或两个X基团的芳基,X基团可以是卤素(例如氟或氯)或烷氧基(例如甲氧基)或一起形成环结构(例如亚甲二氧基或二亚甲基二氧基);C-5取代基是氢H、羟基(OH)或烷氧基(OR1),其中R1是烷基或环烷基;C-6取代基是氢H;C-7取代基是羟基或烷氧基(OR1),其中R1是烷基或环烷基;C-8是氢H、甲基、烷基或取代的烷基,如烷基-Y,其中Y表示(NR2R3)、羟基、酯,例如乙酰氧基、烷氧基,其中R2和R3独立地为H、烷基(例如C1-8烷基)、或者C-6和C-7一起形成包含一个氧的环结构、或者C-7和C-8一起形成包含一个氧的环结构。
本发明的另一方面包括本发明的一种或多种3-芳基-4H-色烯-4-酮或其一种或多种药学上可接受的盐的药物组合物,例如一种或多种式(I)和/或式(II)的化合物和/或一种或多种根据式(I)和/或(II)的化合物的药学上可接受的盐与药学上可接受的添加剂(例如药学上可接受的载体或赋形剂)的组合。在本发明的一个方面,药物组合物包含有效量的至少一种3-芳基-4H-色烯-4-酮或其药学上可接受的盐。
本发明的另一方面包括在制备治疗前列腺癌药物中的应用。该应用包括向有此需要的患者施用有效量的本发明的一种或多种3-芳基-4H-色烯-4-酮或其药学上可接受的盐或其药物组合物。
对本领域技术人员而言本发明的另外的优点将从下面的详细描述中变得显而易见,其中仅通过预期实现本发明的最佳模式来示出和描述本发明的优选实施方式。如将认识到的,本发明能够具有其他和不同的实施方式,并且在不脱离本发明的情况下,其多个细节能够在各种显而易见的方面进行修改。
具体实施方式
本发明涉及能用于治疗前列腺癌的3-芳基-4H-色烯-4-酮。围绕与富含异黄酮家族的天然产物的食品消费相关的健康益处有相当多的学问。特别地,含有7-羟基异黄酮(例如黄豆苷原(A)和染料木黄酮(B))的大豆产品引起了关于癌症预防和前列腺癌治疗的所谓益处的关注。参见(a)Munro,I.C;Harwood,M.;Hlywka,J.J.;Stephen,A.M.;Doull,J.;Flamm,W.G.;Adlercreutz,H.Nutr.Rev.2003,61,1;(b)Adlercreutz,H.Scand.J.Clin.Lab.Invest.1990,50,3;(c)Andres,S.;Abraham,K.;Appel,K.E.;Lampen,A.Crit.Rev.Toxicol.2011,41,463。可惜的是,天然存在的异黄酮及其代谢物拥有众多的生物学活性,包括对雄激素受体表达和与雄激素代谢相关的酶的作用。Hamilton-Reeves,J.M.;Rebello,S.A.;Thomas,W.;Slaton,J.W.;Kurzer,M.S.J.Nutr.2007,137,1769。
我们发现,从这些天然产物中去除一些羟基并且用有氢键合和范德华相互作用力的官能团替代这些基团导致具有独特生物学目标的新试剂。
本发明的优点包括可用于治疗前列腺癌或在有此需要的患者中治疗或抑制复发性前列腺癌的3-芳基-4H-色烯-4-酮或其药学上可接受的盐。本发明的3-芳基-4H-色烯-4-酮包括式(I)的化合物或其药学上可接受的盐:
其中Ar表示芳基,例如苯基,或杂芳基,例如吡啶、二嗪基、嘧啶基、噁唑基或咪唑基。变量n表示Ar上X基团的数目,其可以使1-5的整数。每个X,例如X1、X2、X3、X4和/或X5独立地为卤素,例如氟、氯或溴,或烷氧基(-OR1,其中R1是烷基或环烷基),或者Ar上多于一个X一起形成环醚结构,例如Ar上的X1和X2一起形成-O-R-或-O-R-O-环,其中R为双自由基有机基团。这些基团的实例包括亚甲二氧基、二亚甲基二氧基等。3-芳基-4H-色烯-4-酮在其C-2、C-5、C-6、C-7、C-8位各自被取代。这些位置上的每个取代基可以相同或不同,并且包括氢H;羟基(OH);烷基或环烷基;例如甲基、乙基、环丙基;烷氧基;-COR1,例如乙酰基(-COCH3);酯等。此外,C-6和C-7上的取代基或C-7和C-8上的取代基可以一起形成取代或未取代的、饱和或不饱和的环状或多环结构,其包括至少一种氧族元素,例如氧或硫。在本发明的一个实施方式中,化合物在C-2位被H、烷基或环烷基取代,在C-5、C-6、C-7和C-8位置独立地被H、羟基(OH)、烷基或环烷基、烷氧基(-OR1,其中R1是烷基或环烷基)取代,或者C-6和C-7上的取代基或C-7和C-8上的取代基一起形成取代或未取代的、饱和或不饱和的环状或多环结构,其包括至少一个氧族元素。
对各种基团和取代基而言所述的烷基、环烷基、烷氧基和环结构可以是未取代的或取代的。例如,烷基、环烷基、烷氧基和环结构可以被胺(NR2R3)、羟基、酯(例如乙酰氧基、烷氧基、羰基)取代,其中R2和R3独立地表示H、烷基,例如C1-8烷基。在一些实施方式中,C-7和C-8独立地可以是CH2OY1,其中Y1是氢、烷基,例如甲基、乙酰基等。
在本发明的一个实施方式中,3-芳基-4H-色烯-4-酮是式(II)的化合物或其药学上可接受的盐:
其中C-2、C-5、C-6、C-7、C-8、X和n如上定义,包括其所有实施方式。
包括式(I)和式(II)化合物的本发明化合物,可以通过本文发明的方法或其他本领域已知的方法制备。例如,向苯酚和β-萘酚应用Betti反应(也称为曼尼希反应)的立体选择性提供了一系列取代的芳族体系,并且在本发明中适用于制备取代的3-芳基-4H-色烯-4-酮。参见(a)M.Betti,Gazz.Chim.Ital.,1900,30,301-309;(b)M.Betti,Gazz.Chim.Ital,1900,30,310-316;(c)M.Betti,Gazz.Chim.Ital,1906,36,392-394;(d)L.O.Paquette,Ed.,Encyclopedia of Reagents for Organic Synthesis,1995,Wiley,UK,4,2582。天然异黄酮,如来自大豆的染料木黄酮(B),用于前列腺癌预防和治疗的临床试验。参见Perabo,et al.,Prostate Cancer and Prostate Diseases,2008,11,6-12。
在开发合成3-芳基-4H-色烯-4-酮作为抗肿瘤剂的过程中,我们探讨了Betti反应在异黄酮中的应用。开发这些新的3-芳基-4H-色烯-4-酮的理论基础来源于天然存在的异黄酮作为抗肿瘤剂的低效能和天然存在的异黄酮及其代谢物的非特异性生物学效应。天然存在的染料木黄酮(B)在不同癌细胞系中的IC50仅为约15-100μM,天然异黄酮作为抗肿瘤药物的具体生物学靶标尚不清楚。在本发明中,使用前列腺癌PC3细胞系的增殖测定法提供了在C-2位取代的,或者在C-6或C-8位乙酰氧基甲基-、羟甲基-和甲氧基甲基-取代的3-芳基-7-羟基-4H-色烯-4-酮1和2以及环状对应物(其中在C-6和C7或C7和C8之间存在取代或未取代的、饱和或不饱和的环状或多环结构的,其包括至少一个氧族元素,例如氧或硫)内查看构效关系(SAR)的合理替代(方案1)。
方案1.生物活性的3-芳基-4H-色烯-4-酮1和2
相关天然产物中抗肿瘤活性的文献报道包括色酮如8-(甲氧基甲基)异丁香酚,其显示出对P388白血病细胞的中等细胞毒性。参见Y.Feng,J.W.Blunt,A.L.J.Cole and M.Η.G.Munro,J.Nat.Prod.2002,65,1681-1682。像这样的报道是有限的,因为在自然界中不容易发现8-(羟甲基)异黄酮。因此,本发明揭示了这些各种取代的类似物以及可用于治疗前列腺癌的生物活性化合物的通用合成途径。
使用双(N,N-二甲氨基)甲烷在1,4-二氧六环中在70℃下将Betti反应应用于羟基化的3-芳基-4H-色烯-4-酮提供了进入二甲氨基甲基取代体系的途径,并且随后的操作提供所需的乙酰氧基甲基、羟甲基和烷氧基甲基衍生物用于生物学评估。参见例如Tramontini et al.,Mannich Bases-Chemistry and Uses,1994,CRC Press,Boca Raton,FL。合适的起始材料的合成包括在碳酸钾存在下使用硫酸二甲酯使5,7-二羟基异黄酮中C-7羟基的立体选择性甲基化,以得到5-羟基-2',7-二甲氧基异黄酮(3a)和4',7-二甲氧基染料木黄铜(3b)(方案2)。
方案2.3-芳基-4H-色烯-4-酮或3-芳基-2-甲基-4H-色烯-4-酮3的Betti反应。图例:a.CH2(N(CH3)2)2,DMF,回流。
与经历双-氨甲基化的5,7-二羟基取代的3-芳基-4H-色烯-4-酮相反,5-羟基取代的3-芳基-4H-色烯-4-酮3a和3b在1,4-二氧六环中与双(N,N-二甲氨基)甲烷经历单-氨甲基化,以分别得到6-和8-(N,N-二甲基氨甲基)衍生物4a-4b和5a-5b的混合物,(方案2)其中C-6异构体占支配地位。这些异构体的结构通过HMBC NMR光谱法进行评估。6-(N,N-二甲氨基)甲基衍生物4a和4b具有H-2与C-8a以及H-8与C-8a的交叉峰。在化合物5a和5b中观察到相似的H-2与C-8a以及C-8处的亚甲基质子与C-8a的交叉峰。C-7羟基化的3-芳基-4H-色烯-4-酮3c-3e与双(N,N-二甲氨基)甲烷在异丙酮或1,4-二氧六环中的氨甲基化仅得到了8-N,N-二甲氨基的衍生物5c-5e。总之,5-羟基化和7-羟基化的3-芳基-4H-色烯-4-酮以双(N,N-二甲氨基)甲烷经历所需的氨甲基化,并在C-5羟基化的情况下表现出区域选择性,有利于C-8(二甲氨基)甲基衍生物4,以及在C-7羟基化的情况下表现出立体选择性,有利于C-6(二甲氨基)甲基衍生物5。
将Betti碱4和5直接转化成相应的C-6或C-8乙酰氧基甲基衍生物包括在乙酸钾存在下加热Betti碱4a-4b或5a-5e与乙酸酐,以良好的产率得到相应的二乙酸酯6和7(方案3)。
方案3.将Betti碱4和5分别转化成乙酰氧基甲基衍生物6和7。图例:a,Ac2O,KOAc。
用比例为2:1的0.2M含水硫酸在1,4-二氧六环中对6a-6b或7a-7e进行水解,分别提供了相应的羟甲基3-芳基-4H-色烯-4-酮8a-8b或9a-9e(方案4)。在甲醇中用盐酸对二乙酸盐6和7进行水解直接分别导致了C-6或C-8-甲氧基甲基3-芳基-4H-色烯-4-酮10和11。甲醇的乙醇或异丙醇替代如所预期的导致了其他烷氧基甲基取代的类似物。在甲醇中用盐酸处理8-羟甲基3-芳基-4H-色烯-4-酮提供了8-甲氧基甲基类似物,在甲醇中用氢氧化钠处理8-乙酰氧基甲基衍生物也导致了8-甲氧基甲基3-芳基-4H-色烯-4-酮(方案4)。
方案4.乙酰氧基甲基衍生物6和7向羟甲基和羟甲基衍生物的转化。图例:a,0.2MH2SO4,aq.1,4-二氧六环;b,HC1,MeOH;c,NaOH,MeOH。
使用体外PC3前列腺癌细胞系的筛选程序显示,数个具有C-8乙酰氧基甲基、羟甲基或烷氧基甲基取代基的7-羟基化3-芳基-4H-色烯-4-酮2在1-10μM范围内表现出抗肿瘤活性(表1)。通常,我们观察到C-8取代的类似物7、9和11分别比C-6取代的类似物6、8和10在10μM浓度下更有效。在C-8系列中,乙酰氧基甲基和羟甲基-3-芳基-4H-色烯-4-酮比相应的烷氧基甲基取代的3-芳基-4H-色烯-4-酮更有效。同样在C-8系列中,具有4-甲氧基苯基的3-芳基-4H-色烯-4-酮通常优于具有2-甲氧基苯基的那些。例如,3-芳基-4H-色烯-4-酮7d和7e比7c更有效;3-芳基-4H-色烯-4-酮9b、9d和9e比9c更有效;3-芳基-4H-色烯-4-酮11b比11c更有效。还探索了3-苯基上的除甲氧基以外的其它取代基,并且具有卤素的取代基也具有生物活性。最后,在C-8系列中,具有7-羟基取代基以及8-乙酰氧基甲基或8-羟甲基(例如7d和7e,9d和9e)的3-芳基-4H-色烯-4-酮通常比具有5-羟基-7-甲氧基的3-芳基-4H-色烯-4-酮(例如,7b和9b)更有效。具有C-8乙酰氧基甲基的3-芳基-4H-色烯-4-酮7d作为有希望的主导结构出现,其即使在1mM浓度下仍保留效力。

总之,3-芳基-4H-色烯-4-酮的C-5或C-7羟基化的Betti反应提供了易于转化为乙酰氧基甲基、羟甲基或烷氧基甲基取代的3-芳基-4H-色烯-4-酮的N,N-(二甲氨基)甲基衍生物。特别地,5-羟基化的3-芳基-4H-色烯-4-酮3a-3b立体选择性地提供了C-6Betti碱4a-4b,其通过二乙酸盐6a-6b导致C-6烷氧基甲基衍生物10a-10b。7-羟基化3-芳基-4H-色烯-4-酮3c-3e的类似反应立体选择性地提供了C-8Betti碱5c-5e,并且源自这些曼尼希碱的二乙酸盐7c-7e经过取代,导致所需的C-8烷氧基甲基衍生物11c-11e。在前列腺癌PC3细胞增殖测定中,数个C-8乙酰氧基甲基、羟甲基或烷氧基甲基取代的3-芳基-4H-色烯-4-酮在低的微摩尔范围内具有有希望的效力。
除了具有上述多种取代基的异黄酮外,我们制备了其中C-6和C-7上的取代基或C-7和C-8上的取代基一起形成取代的或未取代的、饱和或不饱和的环或多环结构(至少包括一个氧原子)的3-芳基-4H-色烯-4-酮。我们还展示了这些异黄酮中的某些的抗肿瘤活性。
嵌入3-芳基-4H-色烯-4-酮平台内的邻亚甲基苯醌的产生和Diels-Alder反应被用来制备具有这些环状排列的3-芳基-4H-色烯-4-酮的稠环类似物。在这方面,我们合成了各种稠环类似物,如取代的3-芳基-9,10-二氢吡喃并[2,3-f]色烯-4-(8H)-酮12和3-芳基-10-甲基-3,4-二氢-2H,6H-吡喃并[3,2-g]色烯-6-酮13(方案5)。

本发明前述Betti反应提供了所需的邻亚甲基苯醌前体的获得,转而又导致了3-芳基-4H-色烯-4-酮的稠环类似物。在回流下在异丙醇中将Betti反应应用至7-羟基异黄酮14与二(N,N-二甲氨基)甲烷,以良好的收率立体选择性地提供了C-8取代的N,N-二甲氨基甲基类似物15(方案6)。如预期的那样,7-羟基-8-甲基异黄酮16得到了异构体C-6类似物17。
