技术领域
本发明涉及药物化学技术领域,是一类新型磷脂胺骨架的吡唑磺胺衍生物的制备方法。
背景技术
α-氨基膦酸盐被认为是有效的抗肿瘤剂,能够通过引入其他基团来有效地改善抗肿瘤活性。许多氨基膦酸盐衍生物已显示出对人的良好抑制活性,作为天然氨基酸类似物,由于这些有机磷化合物的生物学和药理学性质,引起了人们极大的兴趣。
吡唑是一类重要的杂环化合物,广泛分布在自然界中。自从含吡唑环的安替吡啉被发现具有镇痛消炎及退热作用以来,该类化合物因其具有高效、低毒,以及其环上取代基的多方位变换的性质而在药物领域中得到广泛应用。研究发现吡唑类化合物具有消炎、止痛、抑菌、杀菌、抗高血糖、抗癌、抗凝血剂等药理活性。近年来,许多新型吡唑类医药相继商品化,对吡唑类化合物的深入研究已成为当今药物设计合成研究的热点之一。
磺胺类药物为人工合成的抗菌药,用于临床已近50年,它具有抗菌谱较广、性质稳定、使用简便、生产时不耗用粮食等优点。特别是1969年抗菌增效剂——甲氧苄氨嘧啶(TMP)发现以后,与磺胺类联合应用可使其抗菌作用增强、治疗范围扩大,因此,虽然有大量抗生素问世,但磺胺类药仍是重要的化学治疗药物。
基于此,本发明将α-氨基膦酸盐和吡唑构筑于同一分子中,设计合成了一系列一类含磷脂胺骨架的吡唑磺胺衍生物,期望具有更好的生物活性、更高的选择性、更低的毒性。

2.权利要求1中所述一类新型磷酯胺骨架的吡唑磺胺衍生物的制备方法包括如下步骤:
步骤一:将多种取代的醛(1mmol)、亚磷酸二乙酯(1mmol)、乙酸铵(1mmol)以及三氟甲磺酸铝(0.02mmol)投于反应瓶中,100℃油浴过夜,反应结束后用稀盐酸水洗,乙酸乙酯萃取4-6次取水相;再用NaOH将pH调至中性或偏碱性,用乙酸乙酯萃取4-6次取有机相,最后将有机相减压真空浓缩得氨基膦酸盐衍生物。
步骤二:将1mmol多种取代的芳香酮和2mmol草酸二乙酯溶于15ml甲醇溶液中,溶解后加入2mmol甲醇钠,TLC跟踪反应,反应结束后,冷却到室温将反应液倒入稀盐酸水中,抽滤得第二步产物;
步骤三:将第二步产物溶于甲醇中,加入1.2mmol对肼基苯磺酰胺盐酸盐,于70℃油浴回流。反应结束后,稀盐酸水洗后用乙酸乙酯萃取后减压浓缩得到第三步产物;
步骤四:将第三步的产物(1mmol)与NaOH(4mmol)分别加入反应瓶,在甲醇下回流12h,及时跟进反应进度,如反应不完全,可补加NaOH。反应结束后,加稀盐酸水洗,用乙酸乙酯萃取减压浓缩得到第四步产物;
步骤五:在0℃下,加入第四步产物(1mmol),DMAP(0.5mmol),HOBT(1.2mmol),EDC(1.2mmol)于无水CHCl2,搅拌0.5h-2h,及时点板监测,在测到活性酯后,加入氨基膦酸盐衍生物(2mmol),转移至室温反应过夜,过柱纯化得终产物。
