Description

具有生物活性的多取代苯化合物及其制备方法和应用
技术领域
本发明涉及药物化学领域,具体涉及具有生物活性的多取代苯化合物及其制备方法和应用。
背景技术
肿瘤疾病是人类和其他哺乳动物最主要的死亡原因之一,该病的特征为细胞增生不受正常细胞增生的控制。我国抗肿瘤药物的生产研发已经取得了长足进步,但产品还远远不能满足临床日益增长的需要,许多还依赖进口,因此开发生产抗肿瘤药物市场潜力依然巨大。传统的化疗药物临床上治疗效果明显,缺点在于:特异性低,选择性差,导致明显的毒副作用,容易产生严重的肿瘤多药耐药现象,限制了临床的应用,寻找安全和有效的抗肿瘤药物一直是医药界的追求目标。
苯环是有机化学中最重要的结构单元之一,其上有6个氢原子可以被取代,这使得苯在医药、农药、塑料和有机电子器件领域具有众多衍生物。同时,作为许多天然活性化合物的基本骨架,以及许多具有药理活性的杂环化合物的合成子,它在药物化学中也扮演重要角色。
多取代苯化合物一般具有较强的生物活性,其生物活性包括抗真菌活性、抗炎活性、抗肿瘤活性、抗氧化活性、抗内风湿活性、抗血小板活性等。如槲皮素,具有显著抑制促癌剂的作用,能抑制离体恶性细胞的生长,并且抑制艾氏腹水癌细胞DNA、RNA和蛋白质的合成;又如赤星衣酸甲酯,具有显著抑制XWLC-05、HepG2以及MCF-7细胞的增殖的作用。
合成多取代苯类化合物的传统方法主要是取代反应,包括亲电取代(如傅克烷基化反应和傅克酰化反应),亲核取代和偶联反应。这些方法往往需要苛刻的反应条件,昂贵的试剂或对环境有害的金属催化剂而且操作过程繁琐、反应区域选择性不高等缺点。
因此,研究合成一系列应用于药物制备的多取代苯环化合物,简化制备工艺,从而规模化获得具有应用于抗肿瘤等药物制备用途的多取代苯环化合物,具有重要意义。
