本发明涉及一种具有抗肿瘤药物功效的联合用药物。
恶性肿瘤是当前人类健康的主要杀手,是严重威胁人类生命的最主要的疾病之一。肿瘤综合治疗主要是外科手术、放射治疗和肿瘤化疗。药物在恶性肿瘤化疗中发挥着重要作用。近年来,抗肿瘤药物的研究与开发工作使肿瘤化疗取得很大进步,上世纪卡铂、紫杉醇等药物的应用,使某些特定肿瘤有了很高的治愈率。但由于抗肿瘤药物存在选择性差,毒副作用大,耐药性等缺陷,目前仍有半数以上肿瘤患者对治疗无反应或耐药而最终导致治疗失败,特别是实体肿瘤的治疗。

试验结果见表7:由表7可以看出,DX1002与多西他赛联合用药治疗Lewis肺癌,抑瘤率为89.61%,而DX1002与多西他赛单独使用的抑瘤率仅50.28%和53.65%,经金氏方程的Q值计算,本发明DX1002与多西他赛(二者的重量比为640:1)联合使用的Q值为1.16,大于1.15的协同限量值;另外,动物体重无明显降低,也未见明显毒性相加反应。

实验结果说明,治疗肺癌时,本发明DX1002与多西他赛联合使用可以发挥协同增效的作用。
实施例8DX1002联合BON对人体结肠癌HT-29的疗效
1、实验材料
试药:盐酸博来霉素(BON,批号:151102,规格:1.5万单位),公司生产,临用前用灭菌生理盐水配制需浓度。
DX1002的制备方法同实施例1。
动物:BALB/C裸鼠(SPF级,体重:19-21g,雄性)。
动物数:8只/组。
瘤株:人体结肠癌HT-29,由四川大学华西医学中心提供。
2、试验方法
取生长良好的结肠癌HT-29瘤块,无菌条件下切割成3mm大小的均匀小块,用套管针每只小鼠右腋皮下接种一块,设以下4组,给药组每组8只,Control组大于8只,分别为:
1)DX1002 200mg/kg(ig,qd×14)
2)BON 1mg/kg(ip,qod×14)
3)DX1002 200mg/kg(ig,qd×14)+CBP 1mg/kg(ip,qod×14)
4)Control
接种后14天见瘤块体积平均约100mm3,根据肿瘤大小重新分组,淘汰肿瘤过大和过小的动物,每组肿瘤平均体积基本一致,开始按以上方案给药,连续经口灌胃14天,给药体积为0.5ml/20g体重。BON腹腔注射,0.2ml/20g体重,隔日一次,连续14天。自接种第14天起每周2次用数显电子卡尺测量肿瘤长径和相垂直的肿瘤短径。接种后29天处死动物。
3、实验结果
试验结果见表8:
与Control组比较:*P<0.05,**P<0.01。
由表8可以看出,DX1002与盐酸博来霉素联合用药治疗结肠癌HT-29,抑瘤率为86.29%,而DX1002与盐酸博来霉素单独使用的抑瘤率仅48.87%和5.31%,经金氏方程的Q值计算,本发明DX1002与盐酸博来霉素(二者的重量比为400:1)联合使用的Q值为1.16,大于1.15的协同限量值;另外,动物体重无明显降低,也未见明显毒性相加反应。
实验结果说明,治疗结肠癌时,本发明DX1002与盐酸博来霉素联合使用可以发挥协同增效的作用。
综上,本发明反式苯乙烯酸类衍生物与抗肿瘤药物的联合使用可以发挥协同增效作用,与部分抗肿瘤药物联合使用还可以发挥降毒的作用,将反式苯乙烯酸类衍生物与抗肿瘤药物制成联合用药物的疗效优良,毒性小,临床应用前景良好。
