Description

化合物DX-52-1的稳定方法和其冻干组合物
技术领域
本发明涉及稳定DX-52-1及其衍生物的方法。
背景技术
如美国专利4650869所述,下式(I-1)的DX-52-1及其衍生物已知具有抗肿瘤活性。
Figure A9519277700041
然而,DX-52-1及其衍生物(以下统称为“DX-52-1衍生物”)在水溶液中容易分解。例如,当在PH7或更高的碱性条件下,DX-52-1在水溶液中相对稳定,但DX-52-1不具备充分的长期保存性和稳定性。因此有必要开发一种可长期保存的稳定的DX-52-1制剂。
本发明的公开
本发明的目的是克服现有技术中的这些不足。
本发明一方面提供一种稳定式(I):其中,R是氢或低级烷基,所示DX-52-1衍生物的方法,该方法包括,制备含有DX-52-1衍生物和至少一种糖的溶液,将所述溶液冻干,所述溶液的PH是7-12。
本发明还涉及含有式(I)的DX-52-1衍生物和至少一种糖的干燥组合物。
本发明涉及一种使式(I)DX-52-1衍生物的组合物保持长期稳定的方法。低级烷基优选是含1-6个碳原子的直链或支链烷基。最优选的低级烷基是甲基、乙基、丙基、异丙基、丁基、仲丁基、叔丁基、戊基和己基。
式(I)所示DX-52-1衍生物可按照美国专利4650869中公开的方法制备。该′869号专利给出了DX-52-1的冷冻干燥制剂,但它不含下文实施例1中的糖。
下表1列举了适于在本发明中使用的DX-52-1衍生物。
表1
下面详细描述本发明。
将式(I)所示的DX-52-1衍生物和一种或多种糖溶于溶剂中。优选地,常用盐酸水溶液和氢氧化钠水溶液将该混合溶液的PH调至7-12。在无菌条件下使所得溶液滤过滤膜,然后冻干。
具有代表性的糖的实例是乳糖、蔗糖、棉子糖、葡聚糖、甘露糖醇、肌醇、半乳糖、核糖、木糖、甘露糖、纤维素二糖、麦芽糖、麦芽三糖、麦芽四糖和海藻糖。优选使用乳糖。使用的糖浓度是0.005-1,000mg/ml,优选1-500mg/ml。
溶解DX-52-1衍生物和一种或多种糖的溶剂没有特别限定。优选的溶剂可保持PH在7-12范围或者允许加入盐酸水溶液或氢氧化钠水溶液。除水以外,优选的溶剂实例包括缓冲溶液,如柠檬酸/磷酸氢二钠缓冲液,磷酸盐缓冲液,硼酸盐缓冲液,醋酸盐缓冲液和柠檬酸盐缓冲液。可按需要使用浓度是0.001-0.5M的这些缓冲溶液。
如果需要,依据制剂目的的不同,本发明的制剂还可含有可药用添加剂,如抗氧剂、抗菌剂、缓冲剂、麻醉剂、增溶剂、增溶辅助剂、等渗剂、防腐剂、稳定剂、载体、粘合剂、崩解剂、润湿剂、润滑剂、着色剂、芳香剂、矫味剂、包衣剂、悬浮剂、润滑剂、增塑剂和表面活性剂。适宜添加剂的实例是抗氧剂,如抗坏血酸、维生素E、丁基羟基甲苯和苄基羟基甲苯;抗菌剂,如对羟基苯甲酸盐和氯代丁醇;缓冲剂,如磷酸和柠檬酸;麻醉剂,如苄醇和利多卡因;载体,如结晶纤维素、羟丙基淀粉、淀粉和玉米淀粉;粘合剂,如Pluran、聚乙烯醇和羟丙基纤维素;崩解剂,如羧甲基纤维素和交联羧甲基纤维素钠A;及润滑剂,如硬脂酸镁、滑石粉和硬化油。
所期望的DX-52-1衍生物的溶解浓度是0.001-1,000mg/ml,优选是0.1-50mg/ml。该溶液的冻干可如下进行:在-50℃预先冷冻5小时,在-30℃和0.05毫巴下初步干燥35小时,而后在0℃和0.05毫巴下干燥15小时,再在25℃和0.05毫巴下进行二次干燥10小时。
然后用橡胶塞和铝帽密封如此冻干的DX-52-1衍生物制品,以供重新配制或注射。这样,本发明的冻干产品直接提供了一种含有生理糖的可注射溶液,与′869号专利第3栏第11-14行相对应。另外,可将该冻干制品掺入口服剂型,如片剂、丸剂、胶囊剂和颗粒剂;及栓剂中。为制备口服或栓剂施用的药物组合物,任何有用的可药用载体均可使用。例如,口服施用的液体制剂,如悬浮液和糖浆的制备可使用水、糖(如蔗糖、山梨醇和果糖)、二元醇(如聚乙二醇和丙二醇)、油(如芝麻油、橄榄油和豆油)、防腐剂如对羟基苯甲酸盐、香味剂如草莓香精和薄荷等。粉剂、丸剂、胶囊剂和片剂的制备可使用赋形剂如乳糖、葡萄糖、蔗糖和甘露糖醇、崩解剂如淀粉和藻酸钠、润滑剂如硬脂酸镁和滑石粉、粘合剂如聚乙烯醇、羟丙基纤维素和明胶、表面活性剂如脂肪酸酯、增塑剂如甘油等。由于便于施用,片剂和胶囊剂是最常用的口服单位剂型。可使用固体药物载体来制备片剂和胶囊剂。
当含有DX-52-1衍生物的制剂被用作抗癌剂时,剂量依如患者年龄、体重和健康状况等因素而不同。当作为注射剂施用时,例如每日的推荐剂量是0.01-50mg/Kg体重,通常以单次剂量给予(只施用一次或连续施用),如每周或每三周1-3次。
