Description

喜树碱衍生物在制备用于治疗多发性骨髄瘤的药物中的用途
技术领域
本发明涉及医药领域, 具体涉及抗癌药领 ¾:, 更具体涉及小分子药物化合物医药用途。 背景技术
多发性骨髓瘤 (multiple myeloma ) 是一种浆细胞的恶性克隆性疾病, 以患者骨髓中恶性 浆细胞克隆性增生为特征, 在造血组织肿瘤屮「' 10%, 占全部恶性肿瘤的 1%。 目前多发性骨 髓瘤的治疗以化疗和骨髓移植相结合办法进行 (综述: The New England Journal of Medicine 2011, 364:1046-60; Clinical Lymphoma & Myeloma 2009, vol.9, No.4, 278-288), 经有效治 疗, 患者的生命可延长数年 (Blood 200ο, 111:2521-2526)。 在二十世纪末期, 标准化疗药品 为 DNA烷化剂 (例如马法林 (Melphalan )、 环磷酰胺 (cyclophosphamide) )和肾上腺皮激素
(例如强尼松 (Prednisone)、 地塞米松 (dexa ethasone) )。 虽然由以上化疗剂组成的化疗方 案部分患者初治有效, 但这些患者在几个疗程后都不可避免地对以上化疗剂产生耐药性, 导 致病症复发和治疗失败。 稍后, "致畸剂" 的沙利度胺 (thalidomide ) 及其衍生物来那度胺
( lenalidomide), 泊利度胺 ( Pomalidomick ) 作为免疫调节剂被发现可以加强 DNA垸化剂和 肾上腺皮激素药物的治疗效果, 在 2000年左右 批准加入临床治疗。 2003年, 蛋白体酶抑制 剂硼替佐米 (Bortezomid ) 作为新机理化疗剂被批准加入临床治疗, 其对经 DNA烷化剂和肾 上腺皮激素药物的治疗复发或难治的多发性骨髓瘤有一定治疗效果, 可以延长患者生命, 但 经使用几个疗程后也因耐药性出现而失效。 由于上述治疗多发性骨髓瘤的主要化疗剂在临床 使用一段时间后都出现耐药现象, 患者最终都不可避免地面对因癌症复发而死亡的威胁。 因 此, 多发性骨髓瘤抗癌化疗领域迫切需要加入更多具有与现有药物不同药学机理和不交叉耐 药的抗癌化疗剂, 为增加有效治疗方案提供药物基础。
在近年的临床研究中, 拓扑替康被 对多发性骨髓瘤的治疗有针对性, 并对小部分经 DNA烷化剂和贤上腺皮激¾药物的治疗复犮或难治的多发性骨髓瘤有一定治疗效果, 体现了 喜树碱类拓扑异构酶 I 型抑制剂在多发性 fr髓瘤治疗的应用前景。 ϋ Clin Oncol 1998, 16:589-592; Leukemia & Lymphoma 2004, vol.45, No.4, 755-759; Bone Marrow Transplantation 2011, 46: 510-515)。 拓扑替康是天然产物喜树碱的水溶性衍生物, 目前已被批准为临床上治 疗其他多种癌症的化疗剂 (综述: Nature Review/Cancer, October 2006 Vol.6, pp789-802)。 因附 加化学修饰基团的影响, 拓扑替康已被确认是细胞耐药蛋白 ABCG¾/BCRP的底物 ( Cancer Res 1999, 59: 5938-5946)。 ABCG2是一种 ATP结合转运膜表面蛋白,在人的正常细胞和肿瘤组织中 均有表达。 作为有针对性的药物排出泵, ABCG2的高表达可导致肿瘤细胞产生多药耐药现象。 因耐药多发性骨髓瘤细胞中 ABCG2蛋白的^达水平较高, 这些高表达的 ABCG¾ BCR蛋白可以 把拓扑替康泵出这些癌细胞外,导致拓扑替康失去杀死这些骨髓瘤细胞的治疗效果 (Blood 2006, 108(12): 3881-3889; Biochem Pharmacol. 2012, 83( ): 1084-1103) =
因此很有必要发现一种适于药用的新型喜树碱类拓扑异构酶 -I型抑制剂,其一方面对多发 性骨髓瘤癌细胞有好的杀死效果, 另一方面不是细胞耐药蛋白 ABCG¾/BCRP的底物。 能满足 以上要求的适于药用的新型喜树碱类拓扑异构酶 -1 型抑制剂将是多发性骨髓瘤化疗的重要补 充。 发明内容
本发明的一个目的是提供一种喜树碱衍生物在治疗多发性骨髓瘤中的应用, 该药物具有 良好的抑制骨髓瘤生长的效果。
本发明的另一个目的是提供一种喜树碱衍 物在制备用于治疗多发性骨髓瘤的药物中的 用途, 以解决多发性骨髓瘤对现有药物具有耐药性的问题。
