Abstract
本发明涉及通式I的小檗胺衍生物或其药学上可接受的盐,制备这些化合物的方法、包含该化合物的药物组合物及其在制备抗肿瘤药物中的用途。
Description
技术领域
本发明属于天然药物及药物化学领域,并涉及新型5-取代的小檗胺衍生物,及制备这些化合物的方法、包含该化合物的组合物及其在制备抗肿瘤药物中的用途。
背景技术
小檗胺(berbamine,BBM)是从中国中草药小檗属植物中提取的一种双苄基异喹啉类生物碱。
小檗胺具有刺激髓细胞增殖作用,能提高造血干细胞集落因子 (GCSF)的含量,促进骨髓造血干细胞和粒祖细胞的增殖,并向粒系细胞分化,促进白细胞的增生(林传荣等,升白胶(小檗胺)治疗化疗性白细胞减少症的临床观察,中成药,1994,16(7):29)。
小檗胺对细胞毒性T淋巴细胞有抑制作用,对小鼠体外自然杀伤细胞活性有明显促进作用,在体内外可诱生出较高水平白细胞介素II (IL-2),可避免用大剂量IL-2治疗肿瘤时引起的毒副反应。实验证明,小檗胺对辐射损伤小鼠免疫系统有良好防护作用(刘新等,小檗胺对 BALB/C小鼠的免疫调节作用,中国医科大学学报,1996,25(3):229;罗崇念等,小檗胺对小鼠脾细胞毒性T淋巴细胞活性的抑制作用,中国药理学与毒理学杂志,1995,9(2):159-160;葛明珠等,盐酸小檗胺对辐射小鼠的免疫防护作用的实验研究,免疫学杂志,1998,14(4):238)。
中国已经批准盐酸小檗胺片的上市销售,用于治疗各种原因引起的白细胞减少症,包括预防癌症放疗、化疗后白细胞的减少。也报道了小檗胺对细胞增殖的抑制作用,例如小檗胺及其某些衍生物对脑恶性胶质瘤细胞、人宫颈癌细胞、腹水癌细胞及黑色素瘤细胞有明显的抑制作用 (张金红等,小檗胺及其衍生物的结构对宫颈癌(CHeLa)细胞生长增殖的影响,南开大学学报(自然科学),1996,29(2):89;张金红等,小檗胺及其衍生物对恶性黑色素瘤细胞增殖的影响,中草药,1997,28(8): 483;张金红等,小檗胺衍生物(EBB)体内抗肿瘤作用初探,中草药, 1998,29(4):243;段江燕等,小檗胺类化合物对黑色瘤细胞内钙调蛋白水平的影响,中草药,2002,33(1):59)。其中[O-(4-乙氧基)-丁基]- 小檗胺(EBB)为专一性强的CaM拮抗剂,专一性系数高出小檗胺6.5 倍。EBB诱导肺癌细胞凋亡,同时维护主要器官细胞正常生物功能(段江燕等,[O-(4-乙氧基)-丁基]-小檗胺诱导肺癌细胞凋亡的初探,山西师范大学学报(自然科学版),2001,15(4):55)。另一小檗胺衍生物为 O-丹磺酞基小檗胺(DB),其含有疏水性萤光基团。DB对依赖于CaM 的红细胞膜Ca2++Mg2+ATPase抑制活性比小檗胺强25倍;DB对细胞内的颗粒酶磷酸二酯酶活性有明显的抑制作用,且存在剂量与活性的关系。另外,还发现DB对肺癌细胞的作用比小檗胺强,而对人胚肺细胞细胞毒性小,其抑制肺癌细胞除了与抑制原癌基因有关,也与控制失活的抑癌基因有关(张金红等,钙调素拮抗剂O-丹酰基基小檗胺对磷酸二酯酶及肺细胞增殖的影响,南开大学学报(自然科学),200l,34(3): 64)。
一些小檗胺衍生物合成已有报道,在体外试验中显示一定的抗肿瘤活性(European Journal of Medicinal Chemistry 2012,54,867;European Journal ofMedicinal Chemistry 2009,44,3293),但尚无动物药效数据公布。研究已证实小分子化合物小檗胺具有明显抗人白血病作用 (Leukemia Research 2006,30,17),但达到抗白血病和抗肿瘤效果所需药量很大。
因此合成并发展新的具有更好的抗肿瘤活性的小檗胺衍生物是非常必要的。

实施例52:本发明小檗胺衍生物抗人T细胞淋巴瘤和多发性骨髓瘤细胞活性测定
(1)实验材料
肿瘤细胞株:人T细胞淋巴瘤细胞株H9和多发性骨髓瘤细胞株 RPMI8226,购于美国ATCC库。
试剂:
小檗胺(BBM)标准品购自四川什邡普康生化有限公司,
本发明小檗胺衍生物见上表。
主要仪器:细胞培养箱,酶标仪
(2)实验方法
取生长良好的H9和RPMI-8226细胞分别接种到96孔细胞培养板孔内,细胞数为7000个/孔。培养液为含10%胎牛血清的1640细胞培养液。加入不同浓度的小檗胺类化合物,混匀后,置于二氧化碳(5%CO2)细胞培养箱37℃培养72小时。然后用MTT法测定活细胞浓度。在本实验中对照组(不加化合物处理)细胞活力设为100%,并计算出化合物作用后细胞活力(%)和72小时肿瘤细胞半数生长抑制浓度(72小时IC50值)。
(3)实验结果
实验结果见表1。表1显示本发明的小檗胺衍生物能显著抑制T细胞淋巴瘤株H9和骨髓瘤细胞株RPMI8226生长,与小檗胺本身比较,本发明的小檗胺衍生物抗肿瘤细胞活性明显增强。实验结果显示,当小檗胺结构式的5位碳被取代或者酚羟基按照本申请所定义被取代时,所得到的小檗胺衍生物相较于小檗胺表现出更好的抗T细胞淋巴瘤和多发性骨髓瘤细胞活性;当小檗胺结构式的5位碳以及酚羟基同时按照本申请所定义被取代的时候,得到的小檗胺衍生物会表现出比单取代(例如5位碳被取代或者酚羟基被取代)的衍生物显著更好的抗T细胞淋巴瘤和多发性骨髓瘤细胞活性。
表1活性测定(72小时IC50μM)
