Description

一种吲哚取代的二氢异喹啉化合物及其合成方法
技术领域
本发明涉及药物化学领域,具体涉及一种吲哚取代的二氢异喹啉化合物及其制备方法,以及该类化合物作为一类新的抗肿瘤药物先导化合物的应用。
背景技术
2014年年初发布的《世界癌症报告》指出,每年全球有420万人死于癌症,每5名男性和每6名女性,就有1人在75岁之前患癌。癌症是起源于上皮组织的恶性肿瘤,尽管其诊断和治疗技术已取得了很大的进步,但仍然是致死疾病的三大主因之一,并且给人类社会带来巨大的精神与经济压力。目前,化疗、手术治疗、放射治疗已成为治疗恶性肿瘤不可或缺的重要手段。在过去的几十年中,人们在研发癌症化疗试剂先到化合物方面做了非常多的工作,并且有多种化合物也已被证明具有良好的治疗效果。1974年,Naphthyridinomycin化合物被分离出来,并且表现出很好的抗癌疗效,自此,异喹啉化合物作为一类特殊的生物碱而被应用于抗肿瘤研究中,并且被作为先导化合物不断开发出新的衍生物。
异喹啉及其衍生物广泛分布于自然界中,其骨架结构是具有生物活性的化合物必备的结构单位。其在医药、化工领域,异喹啉类生物碱发挥着极为重要的作用,其生物活性广泛,如抗肿瘤、抗菌、镇痛、调节免疫功能、抗血小板凝集、抗心律失常、降压等,特别是在抗肿瘤和心血管疾病领域有良好的作用,如klucpfel等人从Streptomyces Iusitanus中分离的到的天然产物naphthriydinomycin被证实具有抗肿瘤活性。而从黄连等植物中提取的原小檗碱对心血管疾病有较好的作用。因此,异喹啉这类具有潜在生理或药理活性的氮杂化合物的合成便成为了科研人员研究的热点。
吲哚取代的二氢异喹啉化合物引进了吲哚与异喹啉两个特殊的结构单元,将会具有不可预料的潜在生物活性。吲哚取代的异喹啉肼盐化合物已有报道,但是裸露的肼基会具有较大的细胞毒性,不适合应用于药物研发中。而其它合成异喹啉的化合物的方法基本上都需要使用过渡金属催化剂,存在污染环境以及残留的风险。因此,开发一种简洁、高效构建吲哚取代的异喹啉化合物库的方法,并系统研究这些化合物的抗肿瘤活性,对于开发自主知识产权药物具有重要的科学意义与应用价值。
