Description

氨基康普立停衍生物及其应用 技术领域
本发明属于药物化合物的合成制备领域，特别是涉及抗癌类药物化合物的合成、制备，更为具体的说是涉及氨基康普立停衍生物及其合成方法和应用。
背景技术
Combretastatins系列化合物最初是从南非Combretumcaffrum树干中提取分离得到的，该系列化合物具有顺式1,2-二苯乙烯结构。其中CombretastatinA-4，即CA-4(顺式-1-(3,4,5-三甲氧基)苯基-2-(3’-羟基-4’-甲氧基)苯基乙烯)具有最强的抑制微管聚合作用。1997年日本味之素株式会社(AjinomotoCo.)T.Hatanaka等人发现把CA-4的3′位的羟基改造成氨基，其抗癌活性大大提高。但是，Combretastatins系列化合物的水溶性很差，特别是将CA-4的3’位改造为氨基后，其水溶性进一步降低。日本味之素株式会社将氨基CA-4用氨基酸进行了修饰，增加了其水溶性，使其成为针剂能对癌症病人使用。但是研究表明，氨基CA-4用氨基酸进行了修饰后，其分子的毒性会大大增加，人体耐受量降低，不适于临床使用。
因此，对氨基康普立停结构式进行进一步改造，从而在满足不同制剂的水溶性要求，特别是口服制剂类药物剂型的水溶性要求的前提下，降低分子毒性，提高耐受量，保证药物疗效，是本领域技术人员，特别是针对康普立停的研究领域中技术人员关注的重点问题和亟待解决的技术难题。

实施例16 动物急性毒性试验
选取ICR小鼠，体重23±2g清洁级，雄性。给药途径采用灌胃(ig)给药，这与临床拟用口服途径一致。
小鼠按体重随机分为8组：分别为空白对照组、实施例1组、实施例5组、实施例11组、实施例12组、实施例13组、实施例14组及对照品组，其中对照品组采用氨基康普立停丝氨酰胺盐酸盐作为对照品(以下称对照品)。
实施例组中所用药物的制备：按照实施例2中公开的盐酸盐的方法，将实施例1、实施例3、实施例4、实施例5、实施例6、实施例7、实施例8、实施例9、实施例10、实施例11、实施例12、实施例13、实施例14中得到化合物制备成盐酸盐产物。
对照品的制备：以氨基乙氧基康普立停(即本专利实施例1步骤2所得产物)为原料，通过以下方法制备：
(1)将氨基乙氧基康普立停、Fmoc-丝氨酸以及DCC和HOBt溶于DMF中。在搅拌下，反应混合物室温反应5小时，TLC跟踪。反应完成后，冷却，加入乙酸乙酯稀释，混合均匀。过滤，经无水硫酸镁干燥，减压浓缩。然后，经快速柱层析分离得到白色泡沫状物质。
(2)取上述得到的(Z)-1-(3，4，5-三甲氧基苯基)-2-(3-氨基-4-乙氧基苯基)- 乙烯-Fmoc-丝氨酰胺溶于甲醇和二氯甲烷混合溶剂中。在搅拌下，加入2N氢氧化钠溶液，室温反应24小时，TLC跟踪。反应完成后，冷却，加入饱和氯化钠溶液，混合均匀。用二氯甲烷萃取3次，有机层经无水硫酸镁干燥，减压浓缩。然后，经常压柱层析分离得到无色泡沫状物质，即得。
预实验：取上述小鼠48只，实验前禁食不禁水12h，按体重随机分组，每组10只。各药物组按0.25ml/10g小鼠体重灌胃给药1次，水对照组灌胃等体积的蒸馏水。找出LD 100值(100％死亡量)、LD 0(0死亡量)和相应的剂量组间距r值，进行LD 50的测定。
正式实验：取上述小鼠160只，按体重随机分为8组,每组20只。实验前禁食不禁水12h后，各给药组按照0.3ml/10g小鼠体重灌胃给药1次，12h后无死亡情况发生，故进行第二次给药，对照组灌胃等体积水。计算各组一日内给药量；对照组灌胃等体积的水，进行急性毒性实验反应观察并记录14d内小鼠每日体重。通过计算，各药物的经口LD 50计算结果如表1所示：
