Abstract
在通式I的细胞毒性化合物中,R是由C1-C4直链或支链烷基取代的亚甲基、甲基或H,R1选自下组:H、C1-C4直链或支链烷基、甲氧基、甲氧基取代有1至3个氟、卤素;R2是H或者C1-C4直链或支链烷基;X是CH或N;Y是CH或N。
Description
技术领域
本发明涉及在癌症患者中治疗实体癌肿瘤,尤其是弥散性实体癌肿瘤的手段和相应的方法。
发明背景
需要为患弥散性癌症的患者开发新型且有效的抗癌药物。用于实体瘤的药物开发与归因于3-D肿瘤组织中复杂生物物理和代谢情况的特定问题相关联,所述3-D肿瘤组织可能难以在实验性体外系统中模拟。已知缺氧和营养物的受限扩散导致静息和对传统抗癌剂及放射治疗的抗性。此外,抗癌药物必需能够穿透进入肿瘤实质,以有毒浓度接触癌细胞。一些临床应用于治疗实体瘤的药物显示进入3-D肿瘤块的穿透性较差,这也许是其功效有限的原因之一。多细胞球体(MCS)模拟人实体瘤优于2-D单层培养物,并且因此比单层培养物更适用于筛选在实体瘤上有活性的药物。
细胞死亡通常细分为三种细胞死亡类型:凋亡(I型)、自噬性细胞死亡(II型)和坏死(III型)。凋亡由胱冬酶活化介导。自噬是一种用于长寿细胞蛋白和受损细胞器降解的进化上保守机制。自噬的主要特征是自噬体的形成。自噬体的形成需要III类磷脂酰基醇-3激酶的活化,并且还依赖两个泛素样缀合系统(Atg-Atg12和Atg8)。自噬在营养缺失情况中保护细胞,而当自噬受到抑制时细胞经历凋亡。在胱冬酶抑制状况下的细胞死亡过程中也观察到自噬的形态学特征。
发明目的
本发明的首要目的是提供实体癌肿瘤的有效治疗手段。
本发明的另一个目的是提供采用该手段的治疗方法。
本发明的其他目的将通过以下发明内容、以附图形式说明的多个优选实施方式和所附权利要求书而显见。
发明内容
本发明公开了一种有效治疗实体癌肿瘤的手段。该手段是通式I的化合物,其中R是由C1-C4直链或支链烷基取代的亚甲基或甲基或H,R1选自下组:H、C1-C4直链或支链烷基、甲氧基、甲氧基取代有1至3个氟、卤素;R2是H或C1-C4直链或支链烷基;X是CH或N;Y是CH或N;如果R1是H或C1-C4烷基,R2是H或C1-C4直链或支链烷基,X是N且Y是N,则R不包括H或甲基。
R2优选是H。本发明的化合物的优选实施方式包括R=H,R1=6-CH3,R2=H,X和Y=CH;R=CH2C(CH3)3,R1=6-CH3,R2=H,X和Y=N;R=CH2CH3,R1=6-CH3,R2=H,X和Y=N。
根据本发明的优选的方面,该通式的化合物还可在未被R1取代的单-、双-或三-氮杂咔唑基的6、7、8、9位之一上被C1-C4直链或支链烷基取代。
本发明的化合物包含其任何药学上可接受的盐、盐/溶剂复合物、金属复合物(排除带任意Fe2+、Fe3+、Co2+的金属复合物)、溶剂复合物和前药。
本发明的化合物可以其在连接1-吡啶-2-基部分和亚氨基芴-2-基部分的N=C键处为顺式/反式异构体的混合物存在。由于异构化率在生理条件下是相当的,异构体被假定对身体发挥相似或基本相同的药理作用。
本发明的化合物是细胞穿透性铁螯合剂。尽管不希望受理论约束,发明人相信本发明化合物的抗癌作用是基于其铁螯合性质。
本发明的化合物在数种体外和体内模型中显示出细胞毒性作用。该细胞毒性作用存在为线粒体呼吸的降低。已知结肠癌组织含有的葡萄糖浓度为正常组织的约10%,并且有提出癌组织依赖通过三羧酸循环的需氧呼吸(Hirayama A等,Cancer Res 69(2009)4918-4925)。在体外HCT116结肠癌多细胞球体模型中,10μM/L浓度的本发明的化合物产生的细胞死亡对应于50%或更低的存活指数(SI)。在这种应用中,在10μM/L的化学化合物浓度下50%或更低的细胞存活的限制被认为是显著细胞毒性作用并如此界定。对于球体的细胞毒性活性表明,本发明的化合物对增殖的和静息的细胞群都有影响。虽然在常氧条件下在高葡萄糖培养基中本发明的化合物也对单层HCT116结肠癌细胞培养物的细胞增殖有影响,但是葡萄糖饥饿提高了抗增殖活性。
本发明的化合物诱导线粒体功能障碍并且增加对葡萄糖的依赖性。葡萄糖的消耗增加了癌细胞对本发明的化合物的敏感性,导致提高的细胞毒性和凋亡。
本发明公开了本发明的化合物在治疗人实体癌肿瘤中的用途。根据优选的方面,本发明的细胞穿透性铁螯合剂优选与自噬抑制剂联用用于这种治疗。
本发明的另一个优选方面公开了包含本发明的铁螯合剂和药物运载体的药物组合物。本发明的药物组合物可通过任何合适的途径(例如经口或胃肠外)给予。合适的运载体包含,例如二甲亚砜和水性介质,诸如包含二甲亚砜和水的混合物。优选的流体运载体是能够溶解本发明化合物的那些。其它优选的流体运载体,尤其是水性运载体,是以良好分散形式(例如尺寸为10μm或更小的微粒形式)包含本发明化合物的那些。
本发明的另一个优选方面公开了一种治疗人内实体癌的方法,该方法包括给予此人药理学上有效剂量的本发明的铁螯合剂或其药学上可接受的盐、前药复合物。所述药理学上有效剂量优选由本发明药物组合物包含着给予。

实施例7.本发明的化合物是细胞穿透性铁螯合剂
为了测试本发明的化合物的细胞毒性是否取决于铁消耗,先向HCT116细胞中加入氯化铁后再加入本发明的化合物。发现氯化铁完全终止了本发明的化合物对表达野生型p53的HCT116细胞和p53基因已破坏的HCT116细胞的影响。
实施例8.药物组合物
本发明的化合物溶解于包含至少2摩尔当量盐酸的有机溶剂,例如甲醇中。通过加入第二种溶剂,例如乙醇,化合物的二盐酸盐从溶液中以二盐酸盐本身或者与沉淀用溶剂形成的复合物(例如化合物·2HCl.EtOH)形式沉淀出来。二盐酸盐/乙醇复合物是本发明的化合物用于药物组合物的优选实施方式。其优选以冷沉淀物的形式使用。如果需要,该冷沉淀物可与标准粉末药物赋形剂如甘露醇、淀粉和微晶纤维素一起整合入片剂中。该赋形剂应该是低碱性的。当在水中悬浮时,它们不应该使pH升至超过7.0,而是提供5.0-7.0的pH。
用含0.1mg/L至15mg/L的二盐酸盐/乙醇复合物的5%甘露醇水溶液(用于提供等张性)进行室温稳定性研究。发现越弱的溶液降解越快。例如,在储存100小时后每升包含15mg化合物的溶液约2.5%的化合物11降解,而每升包含2mg化合物的溶液中约5%的化合物降解,并且每升包含0.1mg化合物的溶液中约三分之一的化合物降解。HPLC揭示了数种降解产物的形成。
