Abstract

本发明提供山喜多(麦考酚酸吗乙酯)在制备抑制癌症的医药组合物中的用途。

Description

山喜多药物在用于制备抑制癌症的医药组合物中的用途 技术领域
本发明为山喜多药物的新适应症的应用,尤其该山喜多药物具有抑制多种癌症的用途。
背景技术
山喜多(CellCept,Mycophenolate mofetil、麦考酚酸吗乙酯、麦考酚酸莫酯)为一种免疫抑制剂。主成分为mycophenolic acid(MPA、麦考酚酸)的2-morpholinoethyl ester(霉酚酸酯)。MPA为具选择性、非竞争性及可逆的强力纤维核苷单磷酸去氢酶(IMPDH)抑制剂,因此能抑制鸟嘌呤核苷酸合成的重新(denovo)路径而不与DNA结合,MPA对淋巴球造成的细胞生长抑制(cytostatic)强过对其他细胞的作用。CellCept用于预防接受同种异体肾脏移植的病人器官排斥的发生,并可治疗难以控制的肾脏排斥,以及用于接受同种异体心脏或肝脏移植的病人预防器官排斥,皆相当有效。山喜多是早已被FDA所认可的用药,具有大量药物机转及人体研究成果资料。
由于临床应用上的明显差异,因此从来没有人认为山喜多具有抑制癌症细胞的可能性。
癌症长期高居全球死因之首,且罹患癌症人数更是逐年攀升,因此治疗癌症俨然成为重要的课题。一般来说,癌症药物治疗无论是化学治疗或标靶治疗,目的多是让癌细胞无法复制、分裂,来阻断肿瘤的蔓延扩张。根据统计,平均每一万个新药约只有五个能够进入第一期临床试验。进一步,许多癌细胞相继 产生抗药性,使药物的使用成效大幅降低,最终导致癌症治疗失败。由此可见药物开发具有一定的困难程度。
因此,如何能让癌症药物的快速的可以被开发出来,并且尽可能的减少临床失败的机率,在癌症病学上是一个非常急迫又重要的课题。
发明内容
为解决上述的问题,本发明针对山喜多药物进行新适应症的研发,而达到老药新用的目标。
经过实验设计结果显示山喜多药物对正常细胞没有或仅有微小的毒性,但山喜多在肿瘤细胞之间具有选择性的影响。
本发明提供一种山喜多药物在用于制备抑制癌症的医药组合物中用途,其中所述医药组合物包含有效剂量的山喜多药物及药学上可接受的盐类所组成。
本发明一实施例中,其中所述癌症是选自由胸腔相关癌症、腹腔相关癌症、内分泌相关癌症、消化道相关癌症中的一种或多种。
本发明一实施例中,其中所述癌症是选自由骨肉瘤相关癌症、皮肤癌相关癌症、血癌相关癌症中的一种或多种。
本发明一实施例中,其中所述胸腔相关癌症是指肺癌。
本发明一实施例中,其中所述腹腔相关癌症是选自由膀胱癌或/和子宫颈癌。
本发明一实施例中,其中所述内分泌相关癌症是选自由前列腺癌、乳癌及卵巢癌中的一种或多种。
本发明一实施例中,其中所述内分泌相关癌症是选自由胃癌、肝癌、大肠癌、胰脏癌及舌癌中的一种或多种。
本发明一实施例中,其中所述山喜多药物的有效剂量浓度为20~500mg/kg/ 天。

具体实施方式
各种癌症细胞株建立
将不同癌症类型的细胞株进行继代培养,癌症细胞种类包含肺癌、胃癌、肝癌、直肠癌、皮肤癌、子宫颈癌、前列腺癌、膀胱癌、乳癌、血癌、胰腺癌、卵巢癌、舌癌、骨肉瘤、肾脏癌,并且对照组亦使用肾脏(HEK293(Kidney))、肺部上皮细胞BEAS-2B(Lung Epithelial)的正常细胞做测试。(表一)
先将各细胞于培养液培养后,由于各细胞的属性不同,因此针对不同种的细胞也要用相对应的培养液(表一),计算细胞数目,回种2×106细胞数,然后加入培养该细胞株的培养液补至体积为10ml,继续培养2-3天。之后将细胞计数,并分装至96孔盘,其中每孔的细胞数目固定为3000颗,且体积为100ul。
表一、癌症测试细胞株及其培养所用的培养液

细胞存活分析方法
将96孔盘中原有的培养液吸掉,每孔加入浓度10um、体积100ul的市售药物,放置72小时后,每孔再加入100ul已稀释的WST-1试剂,该稀释比例为培养液与WST-1原液的体积比为9:1,最后每个孔盘的总体积为200ul,然后将96孔盘放置于37℃,30~90分钟,利用elisa reader(酶联免疫检测仪)于OD450侦测吸光值,并计算各癌症细胞株的存活率。
