Abstract
本发明提供一种式(I)的二甲基吡啶胺化合物,另提供一种包含金属离子和这类化合物的药物组合物,再提供一种使用这类化合物治疗与含磷脂质丝胺酸进出的细胞相关病症的方法。
Description
技术领域
本发明是关于一种二甲基吡啶胺衍生物及其医药用途,尤指一种用于传输医药试剂至标的疾病部位的二甲基吡啶胺衍生物。
先前技术
磷脂质丝胺酸(PS)是一种膜磷脂质,一般位于健全细胞的膜内表面。在特定环境下,PS亦存在于膜外表面上(参见Leventis et al.,Annu.Rev.Biophys.2010,39,407-27)。
具体来说,PS暴露在癌细胞的外表面上(参见Thorpe et al.,Breast Cancer ResTreat 1995,36(2),237-51;Ran et al.,Int.J.Radiat.Oncol.Biol.Phys.2002,54(5),1479-84以及Thorpe,Thromb.Res.2010,125Suppl 2,S134-137)。此外,近年研究发现PS存在于肿瘤血管及肿瘤衍生的微血管内(参见Stafford et al.,Neoplasia.2011,13,299-308;及Yin et al.,Cancer Immunology Research 2013,1,1-13)。此外,在多种致病粒如细菌及病毒中,PS大量暴露在膜外表面上(参见Huang et al.,Cancer Res.2005,65(10),4408-16;及White et al.,Bioconjug.Chem.2010,21(7),1297-1304)。最终当细胞死亡路径异常时,PS被发现于细胞的外侧表面。举例说明,除了癌症以外的病症,例如神经退化性障碍、心血管疾病、自身免疫性疾病、以及代谢性疾病皆验证了PS的表面位置(参见Smithet al.,Mol.Pharm.2011,8(2),583-90)。因此,PS提供了用于医药试剂输送的有效标的,可应用于治疗上述病症。
现今使用磷脂结合蛋白V(Protein Annexin V)透过连结至PS。然而,此种连结需要大量钙离子(Ca2+),可能会活化“翻转酶(scramblases)”而使邻近正常细胞内的PS外露出来,导致标的到正常细胞的错误情形。
因此,目前亟需发展一种传输试剂,能够选择性连结与疾病相关的PS,以达到医药试剂的专一定位输送。

细胞存活率试验
利用MTS试验(Promega,Madison,WI,USA)检测细胞存活率。详细说明:细胞生长在平底96孔盘中(2500~3000细胞/孔)培养24小时,添加培养液时一并添加预定浓度的待测化合物。细胞再培养72小时,培养结束时,移除培养液并以100μl的3-(4,5-二甲基噻唑-2-基)-5-(3-羧基甲氧基苯基)-2H-四唑鎓/吩嗪硫酸甲酯混合物稀释。接着,细胞再于37℃、5%CO2湿度培养箱中培养1.5小时,使活细胞将四唑鎓盐转成甲臜,此转换是利用BioTekPowerWave-X吸收值微孔盘测量仪侦测于490nm下的吸收率而判定。
将得到的数据使用载剂二甲基亚砜(DMSO)处理的对照组(100%存活率)以及背景值控制组(0%存活率)进行标准化,以确认生长抑制率。IC50值是定义为:相较于载剂处理的对照组,引发细胞存活率下降50%所需的化合物浓度,这些数值是利用GraphPad Prismversion 4软件(San Diego,CA,USA)计算。
下表2显示五个Zn-DPA共轭体的IC50值,即Zn-DPA-(8)、Zn-DPA-(12)、Zn-DPA-(25)、Zn-DPA-(26)、及Zn-DPA-(42);表中同时显示作比较用的两种抗癌化合物的IC50值,即SN-38及CPT-11,参照下方的两化合物的结构。请注意Zn-DPA-(8)、Zn-DPA-(12)、Zn-DPA-(25)、Zn-DPA-(26)、及Zn-DPA-(42)、以及CPT-11为抗癌化合物SN-38的前驱药物,Zn-DPA-(26)、Zn-DPA-(42)、及CPT-11分别含约24%、18%、及58%的SN-38。
表2:Zn-DPA共轭体Zn-DPA-(8)、Zn-DPA-(12)、Zn-DPA-(25)、Zn-DPA-(26)、Zn-DPA-(42)及两种抗癌化合物SN-38及CPT-11的对抗人类癌细胞(SCM-1、MiaPaca2及Colo205)及人类胚胎皮肤纤维细胞Detroit551的IC50值。

[活体抗肿瘤试验]
两种Zn-DPA共轭体Zn-DPA-(26)及Zn-DPA-(42)是用于活体抗肿瘤试验,对抗生长于裸鼠上的Colo205或MiaPaca2肿瘤,步骤如下。
详细说明:Colo205或MiaPaca2细胞培养并维持于含RPMI-1640培养液的烧瓶中,培养液中添加10%FBS。收取1×106个细胞并皮下注射接种制公的裸鼠成鼠的左侧腹部,将平均肿瘤大小约为200mm3的待肿瘤小鼠分成一组。使用数字光标尺测量肿瘤尺寸,并利用公式:体积=(长度×宽度^2)/2计算肿瘤体积(单位:mm3)。
小鼠饲养于配置有空气过滤器和无菌垫料的灭菌笼里,位于国家卫生研究院的实验动物中心,在研究过程中,所有小鼠生活在12小时光照/12小时黑夜的循环下,并供应灭菌水和饲料(自由进食)。
在此试验中,使用one-way ANOVA analysis和Newman-Keuls多重比较法进行分析,Zn-DPA-(26)和Zn-DPA-(42)的多种剂量,即40mg/kg、20mg/kg、及10mg/kg,相较于载剂控制组皆具有显著差异(p<0.05)。Zn-DPA-(26)和Zn-DPA-(42)皆溶于10%DMSO/20%蓖麻油聚氧乙烯醚(Cremophor EL)/70%左旋糖的混合液中,采用静脉注射方式给药,剂量为20mg/kg或10mg/kg,一天一次,连续五天;或剂量为40mg/kg,一周两次,连续两周。CPT-11(40mg/kg)采用静脉注射方式给药,一周两次,连续两周;以及SN-38(10mg/kg)溶于10%DMSO/20%蓖麻油聚氧乙烯醚(Cremophor EL)/10%Na2CO3/60%dextrose左旋糖的混合液中,采用静脉注射方式给药,一天一次,连续五天,共两周。
相较于CPT-11中含有58%的SN-38,虽然包含在Zn-DPA-(26)和Zn-DPA-(42)中的SN-38含量分别仅有24%和18%,在Colo205肿瘤异种移植小鼠模式试验中,这两种Zn-DPA共轭体比SN-38和CPT-11治疗组别更显示出非预期的优异抗肿瘤活性。更具体说明,相较于SN-38(10mg/kg)及CPT-11(40mg/kg)时,Zn-DPA-(26)在10mg/kg及40mg/kg剂量时显示出非预期的优异抗肿瘤活性;并且,同样为非预期地,Zn-DPA-(42)的抗肿瘤活性显示出剂量依附(dose-dependent)现象,且在三种剂量中相较于SN-38(10mg/kg)及CPT-11(40mg/kg)皆显示出更高的抗肿瘤活性。
此外,在MiaPaca2肿瘤异种移植小鼠模式试验中,Zn-DPA-(42)显示出非预期的优异抗肿瘤活性且呈剂量依附(dose-dependent)现象,且在40mg/kg、20mg/kg、及10mg/kg剂量中相较于SN-38(10mg/kg)及CPT-11(40mg/kg)皆显示出更高的抗肿瘤活性。
